Detailed Description

Various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Like elements in the various figures are denoted by the same or similar reference numerals. For purposes of clarity, the various features in the drawings are not necessarily drawn to scale.

Referring to fig. 1 and 2, the present application provides a method for constructing a through pipe of a pre-buried water supply pipe of a shear wall, including: step one, acquiring construction information; fixing the line pipe 2 on the steel bars 1 of the shear wall 3; thirdly, arranging a template outside the steel bars 1 of the shear wall 3, and pouring the shear wall 3; fourthly, picking and chiseling the upper end and the lower end of each wire pipe 2 pre-embedded on the shear wall 3 to form grooves 5; and step five, penetrating the water supply pipe 4 into the wire pipe 2 to finish pipe penetration.

In the present embodiment, the construction information includes the height of the shear wall 3, the diameter and length of the line pipe 2, the diameter and length of the water supply pipe 4, and the required number of each of the line pipe 2 and the water supply pipe 4. It will be appreciated that the height of the shear wall 3 is first determined, and then the length, diameter and location of the service pipe 4 (the conduit 2 to be pre-buried) to be plumbed is determined. Because the thickness of the concrete protective layer is generally 20-30mm, the exposed surface of the embedded conduit 2 can be generally allowed to be exposed, and because the shear wall surface also needs plastering decorative tiles, the exposed surface can be shielded, and the aesthetic property of the shear wall 3 is not influenced. However, in order to fix the embedded conduit 2 better, the entire conduit 2 is embedded in the concrete protective layer.

And in the second step, binding and fixing the wire pipe 2 to the outer side of the steel bar 1 of the shear wall 3 by adopting an iron wire. With each spool 2 pre-buried in the outside of the reinforcing bar 1 of shear force wall 3 is when avoiding the later stage because spool 2 is damaged all unexpected circumstances lead to need change spool 2, picks out chisel fluting 5 with shear force wall 3 and leads to the destruction to structures such as shear force wall 3 internal reinforcement 1, guarantees shear force wall 3's structural strength.

In this embodiment, adopt the iron wire will the ligature is carried out to at least upper and lower both ends of spool 2. The fixing and limiting of each wire pipe 2 are guaranteed, and the wire pipes 2 can be possibly displaced due to the construction processes such as pouring of the shear wall 3 in the later period, so that the problems that the water supply pipe 4 is difficult to penetrate through the pipe and the positioning is inaccurate are solved. It will be appreciated that each conduit 2 is banded at a plurality of locations to prevent problems such as displacement.

In the third step, before the shear wall 3 is poured, two ends of each line pipe 2 need to be plugged. In this embodiment, adopt the sticky tape respectively will the shutoff is carried out at the upper and lower both ends of spool 2, prevents that the concrete from getting into spool 2 avoids causing the difficulty because the jam of spool 2 carries out the poling operation to feed pipe 4, can't advance poling operation scheduling problem even.

In the fourth step, the picking and chiseling of the grooves 5 are based on that the upper end and the lower end of each wire pipe 2 pre-embedded in the shear wall 3 are exposed, and the length of the picking and chiseling grooves 5 is at least 100 mm. In the embodiment, the positions of the upper end and the lower end of each wire pipe 2 pre-buried on the shear wall 3 are provided with the slots 5 with the length of 200mm, so that the pipe penetrating operation of the water supply pipe is facilitated. As will be understood by those skilled in the art, the embedded conduits 2 are mostly in the protective layer of the shear wall 3, especially when the embedded conduits 2 are in the middle of the shear wall 3. The pre-buried positions of the upper end and the lower end of each wire pipe 2 are found through size positioning, the upper end and the lower end of each wire pipe 2 are exposed through a picking and chiseling grooving 5 process, and each water supply pipe 4 is conveniently arranged in the wire inlet pipe 2 in a penetrating mode.

In the present embodiment, the diameter of the conduit 2 is larger than the diameter of the water supply pipe 4, and at least one water supply pipe 4 is accommodated in each conduit 2. For example, the diameter of the conduit 2 is 25mm, the diameter of the water supply pipe 4 is 20mm, and the water supply pipe 4 of 20mm can be easily inserted into the conduit 2 of 25 mm. It will be appreciated that, where conduit 2 is provided with a sufficiently large diameter, two or three service pipes 4 may be provided through one said conduit 2. However, when only one water supply pipe 4 is inserted into each conduit 2, the diameter of the conduit 2 is prevented from being too large than the diameter of the water supply pipe 4. Since the water flow pressure in the water feed pipe 4 may be large, the pipe 2 having a too large diameter may cause the water feed pipe 4 to vibrate largely in a high water pressure state, thereby colliding with the inner wall of the pipe 2 to generate an increased noise.

In the embodiment, the length of the water supply pipe 4 is greater than or equal to the length of the line pipe 2 through which the water supply pipe passes. The water supply pipe 4 is also required to be in butt joint with a water pipe outside the shear wall 3, and the long water supply pipe 4 extending out of the wire pipe 2 is convenient to be in butt joint with other external water pipes.

In the present embodiment, the polyvinyl chloride conduit 2 (also referred to as "PVC") used in each conduit 2 is widely used in building materials and is low in price. The water supply pipes 4 are made of polypropylene (PPR) pipes, which have the advantages of energy saving, material saving, environmental protection, light weight, high strength, corrosion resistance, smooth inner wall, no scaling, simple construction and maintenance, long service life and the like, and are generally applied to drainage and other projects.

The application provides a pre-buried feed pipe poling construction method of shear force wall, through pre-buried spool 2 in shear force wall 3, reduced the later stage and picked the length of chiseling grooving 5 on shear force wall 3 for 1 structure of internal reinforcement of shear force wall 3 is perfect relatively, can not suffer destruction, and the surface of shear force wall 3 is more complete, practices thrift a large amount of manpower and materials simultaneously, has improved efficiency of construction etc..
