In the construction of high-rise buildings, in order to facilitate drainage of each floor, drainage pipes are usually installed through floors at balconies, toilets, kitchens, etc. for drainage. However, when the drain pipe is inserted into the floor, a gap is likely to be formed between the drain pipe and the floor, which may cause water leakage. For example, when a drainage pipe is installed through a balcony, a gap is easily formed between a balcony floor and the drainage pipe, so that accumulated water on a balcony of an upper house leaks into a lower house through the gap. The water seepage problem of the drainage pipe position of the balcony floor penetrating is always an important problem which troubles the engineering construction quality, not only influences the normal use function of a building body and destroys other working procedure achievements, but also influences the life quality of residents, and is a main quality problem with higher complaint rate of the residents.

Furthermore, the leveling layer structure 200 formed on the balcony floor 100 is enclosed around the drain pipe 10 to block the gap between the drain pipe 10 and the balcony floor 100, so as to primarily prevent water from being drained at the position of the drain pipe 10. Furthermore, the leveling layer structure 200 is formed with an anti-seepage groove 310 around the drain pipe 10, and by performing further waterproof construction on the leveling layer structure 200, not only a waterproof layer structure with further waterproof function can be formed on the balcony floor 100, but also a thicker waterproof layer structure can be formed at the anti-seepage groove 310, so that the waterproof effect of the balcony floor and the joint position of the drain pipe and the balcony floor can be further improved. In addition, the tile 600 is spread on the waterproof layer structure, so that the waterproof effect of the balcony floor 100 and the drain pipe 10 can be further enhanced, and the balcony floor 100 can be more beautiful.

Further, before the real-time step S100, that is, "performing leveling construction on a balcony floor, forming a leveling layer structure on the balcony floor, the leveling layer structure being formed with an anti-seepage groove around a drain pipe", the method may further include the following steps:

and S102, cleaning the balcony floor 100 and the drain pipe 10 to enable the surfaces of the balcony floor 100 and the drain pipe 10 to be clean and tidy. Before leveling construction, the surface of the balcony floor 100 is cleaned, accumulated dust, laitance, oil stain and sundries on the surface of the balcony floor 100 are cleaned and washed clean, cement mortar or fine stone concrete is used for leveling an obvious dent, and the smooth part of the surface is roughened and cleaned; the drain pipe 10 penetrating the balcony floor 100 is cleaned, dirt on the outer wall of the pipe protruding from the surface of the balcony floor 100 of the drain pipe 10 is cleaned, and dust and dirt on the balcony floor 100 around the drain pipe 10 are cleaned.

And S104, wetting the balcony floor 100. Before leveling construction is performed, it is necessary to keep the surface of the balcony floor 100 wet. The balcony floor 100 may be wetted by watering the surface of the balcony floor 100, but it is desirable to avoid the formation of water on the surface of the balcony floor 100, which may need to be removed when water is present.

Then, in step S100, that is, "leveling construction is performed on the balcony floor slab, and a leveling layer structure is formed on the balcony floor slab, and the leveling layer structure has an anti-seepage groove formed around the drain pipe", the method includes the following steps:

s110, a groove forming mold is arranged around the drain pipe 10 penetrated by the balcony floor 100 in an enclosing mode, and the shape of the groove forming mold corresponds to that of the anti-seepage groove 310. Namely, during the leveling construction, a groove forming mold may be disposed around the drain pipe 10, so that after the leveling construction is completed, a desired impermeable groove 10 may be formed around the drain pipe 10. When the groove forming mold is provided around the drain pipe 10, the groove forming mold may be hung on the drain pipe 10, or may be fixed to the drain pipe 10 in another manner.

And S120, leveling construction is carried out on the balcony floor 100, a leveling layer structure 200 is formed on the whole balcony floor 100, and the leveling layer structure 200 is arranged around the groove forming die in a surrounding mode. By performing the leveling construction around the groove forming mold, the leveling layer structure 200 may be formed on the balcony floor 100 outside the area surrounded by the groove forming mold.

S130, taking out the groove forming mold arranged around the drain pipe 10, and forming the anti-seepage groove 310 at the leveling layer structure 200 around the drain pipe 10. That is, after the leveling construction is completed and the leveling layer structure 200 is completely formed, the groove forming mold surrounding the drain pipe 10 can be removed, and the required impermeable groove 310 can be formed on the leveling layer structure 200 surrounding the drain pipe 10.

Further, when the "surrounding groove forming mold" in the above step S110 is implemented, the method includes the following steps:

a groove forming mold is arranged around the drain pipe 10, so that the cross section of the groove forming mold is in an inverted trapezoid shape, an inverted triangle shape or a semicircular shape. Thus, the final formation of the impermeable groove 310 corresponding to the shape of the groove forming mold can be achieved, i.e., the impermeable groove 310 having an inverted trapezoid shape, an inverted triangle shape or a semicircular shape can be formed.

In addition, when the above step S120 is performed, that is, "leveling construction is performed on the balcony floor, a leveling layer structure is formed on the entire balcony floor, and the leveling layer structure is arranged around the groove forming mold", the method includes the following steps:

and S122, performing leveling construction on the balcony floor 100 around the drain pipe 10 to form a leveling base layer around the drain pipe 10, wherein the height value of the leveling base layer is one sixth to one fifth of the height value of the leveling layer structure 200. That is, a leveling base layer can be formed under the groove forming mold disposed around the drain pipe 10 to form the bottom layer structure of the anti-seepage groove 310, and a normal leveling layer structure can be formed at a position other than the groove forming mold. Moreover, the thickness value of the leveling base layer is one sixth to one fifth of the thickness value of the leveling layer structure 200, so that the depth of the anti-seepage groove 310 reaches one fifth, four to five sixths of the thickness of the leveling layer structure 200, a waterproof layer structure with enough thickness is formed at the anti-seepage groove 310, and the waterproof effect is better. Moreover, the leveling base layer with the thickness of one sixth to one fifth of the thickness value of the leveling layer structure 200 is formed at the bottom of the anti-seepage groove 310, so that not only can a preliminary waterproof effect be realized, but also the waterproof layer structure and the leveling base layer can be well combined together during subsequent construction, and the sealing is more reliable.

Before leveling construction, dry and hard cement mortar is used for making ash cakes on the balcony floor 100 according to the elevation of the elastic line of the wall surface, and the leveling layer cement mortar is stirred according to a certain proportion; when the ash cake is well made and water is not trapped, uniformly sweeping plain cement mortar on the balcony floor slab 100 once, and paving leveling layer cement mortar while sweeping, wherein the thickness of the leveling layer cement mortar is paved according to the thickness of the attached ash cake; spreading leveling layer cement mortar, then using an aluminum alloy bar to press the height of the ash cake, leveling the leveling layer cement mortar, rubbing and compacting by using a wood trowel, eliminating sand holes, foot marks and the like, and then using a guiding rule to check the flatness; after the leveling layer cement mortar receives water, an iron trowel is used for leveling and compacting for the first time until the mortar starts to be spread. Furthermore, the cured mortar also needs to be calendered and cured.

And S124, arranging a groove forming mold on the leveling foundation layer, and continuing leveling construction around the groove forming mold to form a leveling layer structure 200 around the groove forming mold. That is, the groove forming mold is located above the leveling base layer, so that the bottom wall of the impermeable groove 310 is formed between the groove forming mold and the balcony floor 100 when the leveling layer structure 200 is constructed on the balcony floor 100. Moreover, the groove forming mold can be arranged around the drain pipe 10 before the leveling construction is carried out, and a leveling gap is formed between the groove forming mold and the balcony floor 100; in addition, after the construction of the leveling foundation layer is completed, the groove forming mold may be placed on the leveling foundation layer, and the construction operation of the leveling layer structure 200 may be performed around the groove forming mold.

In addition, when the step S200 of performing waterproof construction on the leveling layer structure and forming a waterproof layer structure on the leveling layer structure is performed, the method includes the following steps:

s210, performing flexible waterproof construction on the leveling layer structure 200 to form a flexible waterproof layer structure 300 on the leveling layer structure 200. Namely, after the leveling layer structure 200 with the anti-seepage groove 310 is constructed and formed on the balcony floor 100, the flexible waterproof layer structure 300 is constructed and formed on the whole leveling layer structure 200, so as to realize flexible waterproof for the balcony floor 100.

S220, performing waterproof protection construction on the flexible waterproof layer structure 300, and forming a waterproof protection layer structure 400 on the flexible waterproof layer structure 300. Namely, after the construction of the flexible waterproof layer structure 300 is completed on the leveling layer structure 200, the construction of the waterproof layer structure 400 is performed on the basis of the flexible waterproof layer structure 300, so that the waterproof effect of the balcony floor 100 is further enhanced, and the flexible waterproof layer structure 300 can be protected.

Further, when the step S210 of performing flexible waterproof construction on the screed-layer structure and forming a flexible waterproof layer structure on the screed-layer structure is performed, the method includes the following steps:

s212, when flexible waterproof construction is carried out on the leveling layer structure 200, flexible waterproof materials are coated on the leveling layer structure 200 on the periphery side of the anti-seepage groove 310. That is, when the flexible waterproof layer structure 300 is constructed on the leveling layer structure 200, the flexible waterproof material is required to be coated on all the leveling layer structures 200 around the anti-seepage groove 310, so as to form the flexible waterproof layer structure 300 on all the leveling layer structures 200 around the anti-seepage groove 310, and thus, the flexible waterproof of the whole balcony floor 100 is realized.

And S214, coating flexible waterproof materials in the anti-seepage grooves 310 to enable the surface of the flexible waterproof layer structure 300 formed on the whole leveling layer structure 200 to be flush. That is, the flexible waterproof material is coated in the anti-seepage groove 310, so that the periphery of the drain pipe 10 is provided with the flexible waterproof layer structure 300, and a good flexible waterproof effect is formed on the periphery of the drain pipe 10. Moreover, the flexible waterproof layer structure 300 is required to fill the whole anti-seepage groove 310, so that the thickness of the flexible waterproof layer structure 300 on the peripheral side of the drain pipe 10 is much greater than the thickness of the flexible waterproof layer structures 300 at other positions, the waterproof effect of the anti-seepage groove on the peripheral side of the drain pipe 10 can be greatly enhanced, and the leakage rate of the peripheral side of the drain pipe 10 can be greatly reduced.

Further, when step S214 is performed, i.e., "the flexible waterproof material is coated in the anti-seepage groove to keep the surface of the flexible waterproof layer structure formed on the whole leveling layer structure to be flush", the method includes the following steps:

s2142, brushing a polyurethane coating from the bottom of the anti-seepage groove 310, and tightly combining the polyurethane coating with the outer wall of the drainage pipe 10. Namely, the bottom of the anti-seepage groove 310 is coated with the polyurethane coating film to form a flexible waterproof layer structure on the periphery of the drain pipe 10, and the polyurethane coating film can be coated on the outer wall of the drain pipe 10, so that the flexible waterproof layer structure 300 formed by the polyurethane coating film is connected with the outer wall of the drain pipe 10 into a whole, and good waterproof and anti-seepage effects are achieved.

S2144, the polyurethane coating film is continuously coated in the anti-seepage groove 310 until the polyurethane coating film fills the anti-seepage groove 310 and is connected with the flexible waterproof layer structure coated on the leveling layer structure 200 outside the anti-seepage groove 310 into a whole, and the surface of the polyurethane coating film coated in the anti-seepage groove 310 is flush with the surface of the polyurethane coating film on the peripheral side. When the polyurethane coating film is coated in the anti-seepage groove 310, multiple layers of polyurethane coating films can be coated, the polyurethane coating films of all layers are tightly connected together, the polyurethane coating films of all layers are brushed on the outer wall of the drain pipe 10 to be tightly connected with the outer wall of the drain pipe 10, the drain pipe 10 is protected layer by layer from the periphery, and the waterproof and anti-seepage effects are better. Moreover, when the polyurethane coating film is coated in the anti-seepage groove 310, each layer of polyurethane coating film is required to be connected with the polyurethane coating film outside the anti-seepage groove into a whole, so that the whole waterproof effect is better.

Furthermore, when the flexible waterproof layer structure 300 is formed by coating the polyurethane coating film on the peripheral side of the drain pipe 10, the drain pipe 10 may be brushed from the outer wall of the drain pipe 10 to the anti-seepage groove 310, and the anti-seepage groove 310 may be brushed to the outer leveling layer structure 20. Moreover, the polyurethane coating film can be continuously coated when the seepage-proofing groove 310 radiates to the peripheral side, or the polyurethane coating film can be coated from a plurality of positions and drawn close to the seepage-proofing groove, and finally the polyurethane coating film in the seepage-proofing groove 310 and the polyurethane coating film on the peripheral side are connected into a whole to form an integral flexible waterproof layer structure.

Moreover, since the anti-seepage groove 310 is configured as an inverted trapezoid, an inverted triangle, or a semicircular groove, the thickness of the flexible waterproof layer structure 300 formed closer to the drain pipe 10 is greater, which has a better effect of preventing leakage between the drain pipe 10 and the balcony floor 100.

In addition, after the construction of the flexible waterproof layer structure 300 is completed, a water closing test needs to be performed for 24 hours, and after the test is qualified, the next construction operation can be performed.

In addition, when the step S220 of performing waterproof protection construction on the flexible waterproof layer structure and forming a waterproof protection layer structure on the flexible waterproof layer structure is performed, the method includes the steps of:

taking the drain pipe 10 as a center, performing waterproof protection construction on the flexible waterproof layer structure 300, forming a waterproof protective layer structure 400 on the surface of the whole flexible waterproof layer structure 300, and enabling the waterproof protective layer structure 400 to be in close contact with the drain pipe 10. Moreover, when the water-proof protection construction is performed on the peripheral side of the water discharge pipe 10, the water discharge pipe 10 may be constructed from the outer wall of the water discharge pipe 10 to the anti-seepage groove 310, and the anti-seepage groove 310 may be constructed on the flexible water-proof structure 300 on the outer side. Moreover, the waterproof protective layer structure 400 can be formed by continuing the construction when the seepage-proofing groove 310 radiates to the peripheral side, or can be formed from a plurality of positions and drawn close to the seepage-proofing groove 310, and finally the waterproof protective layer structure at the seepage-proofing groove 310 and the waterproof protective layer structure at the peripheral side are connected into a whole to form the integral waterproof protective layer structure 400.

Moreover, when the construction of the waterproof protective layer structure 400 is performed, the flexible waterproof layer structure 300 is cleaned first: cleaning and washing impurities such as soil, floating slurry blocks and the like on the surface of the flexible waterproof layer structure 300, and removing accumulated water on the surface; then pasting the ash cake: making an ash cake according to the elevation line, wherein a flashing slope for draining water to the floor drain is made according to the position of the floor drain when the ash cake is made; then, fine stone concrete for waterproof protection construction is prepared, then the fine stone concrete is laid on the flexible waterproof layer structure 300 according to the thickness of the pasted ash cake, when an operator carries out construction, the operator needs to pay special attention to the fact that the flexible waterproof layer structure 300 at the lower side cannot be damaged, an aluminum alloy rod is used for scraping and tamping along with laying, fine stone concrete is used for filling up the surface collapse position, a long aluminum alloy rod is used for scraping once, and a wood rubber is used for rubbing and tamping. And after the construction of the fine stone concrete waterproof protective layer is finished for 24 hours, starting manual watering maintenance, watering not less than twice every day, ensuring that the surface is in a wet state, and maintaining for not less than 7 days.

In addition, the implementation of step S300, namely "tiling the waterproof layer structure", includes the following steps:

and covering a mortar layer structure 500 on the waterproof layer structure, and paving ceramic tiles 600 on the mortar layer structure 500. Namely, after the construction of the flexible waterproof layer structure 300 and the waterproof protective layer structure 400 is completed on the leveling layer structure 200, the tile can be laid on the waterproof protective layer structure 400. When paving and pasting the ceramic tile, the mortar can be coated on the waterproof protective layer structure 400, so that the ceramic tile can be conveniently paved and pasted on the mortar, the connection is firm and reliable, and the waterproof effect can be further enhanced.

Furthermore, when the waterproof layer structure is covered with a mortar layer structure and the mortar layer structure is paved with tiles, the method comprises the following steps:

and S310, with the drain pipe 10 as a center, covering a mortar layer structure 500 on the waterproof layer structure, so that the mortar layer structure 500 is in close contact with the drain pipe 10. Similarly, when the mortar layer structure 500 is constructed around the drain pipe 10, the drain pipe 10 may be constructed from the outer wall of the drain pipe 10 to the anti-seepage groove 310, and from the anti-seepage groove 310 to the outer waterproof protective layer structure 400. Moreover, the construction can be continued to form the mortar layer structure 500 when the seepage-proofing groove 310 radiates to the peripheral side, or the construction can be performed from a plurality of positions and the seepage-proofing groove 310 is closed, and finally the mortar layer structure 500 at the seepage-proofing groove 310 and the mortar layer structure 500 at the peripheral side are connected into a whole to form the integral mortar layer structure 500.

And S320, after the waterproof layer structure is covered with the mortar layer structure 500, paving and pasting the ceramic tiles 600 on the mortar layer structure 500. That is, after the mortar layer structure 500 is coated on the waterproof protective layer structure 400, the tile 600 is laid on the mortar layer structure 500. Moreover, after the mortar layer structure 500 is coated on the whole waterproof protective layer structure 400, the paving of the ceramic tiles 600 on the mortar layer structure 500 can be started; alternatively, after a part of the mortar layer structure 500 is coated on the waterproof protective layer structure 400, the tiles 600 may be applied on the coated mortar layer structure 500.

Through the anti-seepage construction method for the drainage pipe of the balcony floor penetrating, the drainage pipe is more comprehensive and sufficient in waterproof performance, the seamless standard of the position between the drainage pipe and the balcony floor can be achieved, the leakage rate can be reduced, the leakage problem of the drainage pipe of the balcony floor can be effectively controlled, and the later reworking and maintenance cost can be reduced.
