The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

The technical solution in the present application will be described below with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention provides a technical solution, which specifically provides a retaining wall for hydraulic engineering, including a retaining wall assembly 100 and a monitoring assembly 200. The earth wall assembly 100 is mainly used for supporting a roadbed filling soil or a hillside soil body and preventing the filling soil or the soil body from deforming and destabilizing, and the monitoring assembly 200 is mainly used for monitoring the water level of the hydraulic engineering so as to avoid great potential safety hazards.

Further specifically, referring to fig. 1 to 5 in combination, the soil wall assembly 100 corresponding to the hydraulic engineering retaining wall provided in this embodiment sequentially includes a base 110, a wall 120, a platform 130, and a green plant layer 140 from bottom to top, the wall 120 is fixedly connected to the base 110, the platform 130 is fixedly connected to one end of the wall 120 far away from the base 110, and the green plant layer 140 is disposed at one end of the platform 130 far away from the wall 120. It should be noted that the base 110 is a reinforced concrete structure, and plays a role in bearing strength and supporting and fixing; the green plant layer 140 can increase the ornamental value and environmental index of the retaining wall.

Further, wall body 120 includes that buffer layer 121, infiltration layer 122 and frost resistant concrete layer 123 have set gradually from outer to inner, and buffer layer 121 is cellular concrete layer, and it contacts with the soil body, can form the buffering to soil body pressure, avoids the retaining wall body deformation that soil body pressure extrusion leads to, the fracture, even collapse, and buffer layer 121 adopts the foaming cement in addition, because there is a large amount of bubbles in the foaming cement, outside playing the buffering effect, still alleviate wall body 120 overall mass and syllable-dividing effect. The water seepage layer 122 is a pebble layer, pebbles in the pebble layer have the grain diameter of 3-5mm, the pebble layer does not absorb water and has good penetrating power, water entering the retaining wall body from a supporting soil body can be guided into the ground after being filtered by the pebble layer, and the water amount entering the subsequent anti-freezing concrete layer 123 is reduced. The frost resistant concrete layer 123 is built by the frost resistant concrete, and mainly avoids the concrete expansion and cracking. In addition, the anti-freezing concrete layer 123 is provided with a water level groove 1231, the floating block 260 is arranged in the water level groove 1231, the floating block 260 is of a hardened composite foam structure so as to ensure good corrosion resistance and stable and reliable floating attraction action (so that the floating block 260 can move upwards under the buoyancy action of water), and the buffer layer 121 is made of foamed cement. It should be noted that, the use of the foamed cement as the buffer layer 121 can reduce the load of the self-weight, and enhance the rigidity and the shock absorption performance of the buffer layer 121, thereby effectively improving the overall stability and the service life of the retaining wall.

Furthermore, one surface of the buffer layer 121 away from the water-permeable layer 122 is an arc surface and is of an inward concave structure. It should be noted that the concave arc-shaped surface has a larger contact area, and can further bear larger pressure brought by the supporting soil body, and further reduce the pressure brought by the frozen expansion of the supporting soil body to the retaining wall body.

It should be emphasized that the embodiment of the present invention is not limited to the above-mentioned exemplary arc-shaped surface structure of the buffer layer 121, and may also be other types of ways capable of sharing more load-bearing pressure, for example, in other embodiments of the present invention, the arc-shaped surfaces are arranged along the surface of the buffer layer 121, a plurality of arc-shaped surfaces are arranged on the surface of the buffer layer 121 in an array, and preferably, the radius of each arc-shaped surface does not exceed one fourth of the vertical direction of the buffer layer 121; the inner surface of each arc-shaped surface is also provided with a plurality of anti-skid projections arranged in an array. It should be noted that, the radius of each arc-shaped surface is limited not to exceed one fourth of the vertical dimension of the buffer layer 121, because the radius of the arc-shaped surface is too large or too small, which is not favorable for the arc-shaped surface structure to exert the pressure bearing function that should be, too large, the strength and toughness of the buffer layer 121 itself become poor, the originally existing bearing capacity of the buffer layer 121 is lost, and too small, the value of the arc-shaped surface itself is lost, so only the arc-shaped surfaces with the proper number and the proper radius are concave structures, the most ideal specific surface area can be possessed, the buffer layer 121 can bear stronger pressure, and the stress surface of the whole buffer layer 121 is more uniform and stable. Certainly, the inner surface of each arc-shaped surface is also provided with a plurality of anti-skidding bulges arranged in an array, so that a higher specific surface area is further provided for each arc-shaped surface structure from a microscopic angle, and the anti-skidding effect is simultaneously realized on the direction vertical to the stress surface, so that the bearing capacity of the stress is further enhanced, and the stability, uniformity and reliability are further improved.

Further, a plurality of filtering holes 131 are formed in one end, close to the installation box 210, of the platform 130, the filtering holes 131 are all made of stainless steel materials so as to ensure good corrosion resistance (in the field of hydraulic engineering, the relief is complex, atmospheric corrosion and water environment corrosion are severe, and the corrosion resistance of the materials is one of the most important performances in engineering design), and the filtering holes 131 are arranged in an array manner. It should be noted that, through the filtering holes 131, rainwater can be prevented from flushing garbage or weeds on the shore into the river, so that the river is polluted, and the arrangement of the plurality of filtering holes 131 is an optimal mode, which can have good environmental adaptability on the basis of ensuring good passing performance of the filtering holes 131, because the filtering holes 131 are easily blocked by rainwater and garbage together with weeds in actual working conditions, and due to the arrangement of the plurality of filtering holes 131 in an array, the simultaneous blocking of the filtering holes 131 on a plurality of sites can be maximally avoided, so that the functional stability of the filtering holes 131 is ensured.

Further preferably, in other embodiments of the present invention, the plurality of filtering holes 131 includes a plurality of first filtering holes 131 and a plurality of second filtering holes 131, the diameter of the plurality of first filtering holes 131 is the same, the diameter of the plurality of second filtering holes 131 is the same, and the diameter of each first filtering hole 131 and the diameter of each second filtering hole 131 are different in size. It should be noted that, the different sizes of the first filter hole 131 and the second filter hole 131 are set, so that the plurality of filter holes 131 have stronger working condition adaptability.

More specifically, the platform 130 and the fixing block 250 are both provided with a through hole 251, and the push rod 240 is slidably connected to the through hole 251. Preferably, the inner wall of the through hole 251 is provided with a graphene sliding layer, and the thickness of the graphene sliding layer is 1-1.2 mm. It should be noted that, by providing the through hole 251 with the graphene sliding layer having a certain thickness, the sliding of the lift rod 240 in the through hole 251 is more flexible and smooth, and the lift rod 240 is prevented from shaking left and right.

Further, the frost-resistant concrete layer 123 is provided with a water level groove 1231, one end of the frost-resistant concrete layer 123 close to the water level groove 1231 is fixedly connected with a water level guard block 1232, and the floating block 260 is arranged at the joint of the water level guard block 1232 and the water level groove 1231, so that the position of the floating block 260 influenced by the flow of the river can be avoided.

Further, the monitoring assembly 200 in the embodiment of the present invention includes an installation box 210, an alarm 220, a pressure sensor 230, a push rod 240, a fixed block 250, and a floating block 260, wherein the installation box 210 is fixedly connected to the platform 130, the alarm 220 is fixedly connected to the installation box 210, the pressure sensor 230 is in signal connection with the alarm 220, the pressure sensor 230 is disposed in the installation box 210, the push rod 240 abuts against the pressure sensor 230, the push rod 240 is slidably connected to the platform 130 and the fixed block 250, the fixed block 250 is fixedly connected to the wall 120, and the floating block 260 is fixedly connected to one end of the push rod 240 away from the pressure sensor 230. It should be noted that, through the structural design of the monitoring assembly 200, when the water level rises, the floating block 260 receives the buoyancy of water, and then can move upwards, and then can drive the ejector rod 240 to move upwards in the fixed block 250, and then the top of the ejector rod 240 applies upward pressure to the pressure sensor 230, and then the alarm 220 receives the signal of the pressure sensor 230, and then starts to give an alarm, and then people can find the water level rise in time, and then can handle in time, and avoid the occurrence of irretrievable consequences, so the hydraulic engineering retaining wall can monitor the water level, can handle in time the safety problem of the water level rise, and effectively avoid the occurrence of flood hazard.

The embodiment of the invention also provides a construction method of the retaining wall for the hydraulic engineering, which is simple and high in efficiency, not only greatly reduces the construction cost in the hydraulic engineering, but also can be efficiently, stably and properly built to form the retaining wall for the hydraulic engineering, so that the retaining wall for the hydraulic engineering has the advantages of good cost and working condition adaptability when being popularized on a large scale in engineering. Specifically, the construction method of the retaining wall of the hydraulic engineering comprises the following steps:

It should be noted that, when configuring and installing the monitoring assembly 200, the method includes: fixedly connecting the installation box 210 to the platform 130, fixedly connecting the alarm 220 to the installation box 210, connecting the pressure sensor 230 to the alarm 220, and arranging the pressure sensor 230 in the installation box 210, so that the push rod 240 abuts against the pressure sensor 230, and the push rod 240 can be slidably connected to the platform 130 and the fixed block 250 through the through hole 251; the fixing block 250 is fixedly connected to the wall 120, and the floating block 260 is fixedly connected to an end of the ram 240 away from the pressure sensor 230.

It should be specifically emphasized that the working principle of the retaining wall of the hydraulic engineering in the embodiment of the invention is as follows: when the water level rises, the floating block 260 is subjected to the buoyancy of water and then moves upwards, so that the ejector rod 240 is driven to move upwards in the fixed block 250, the top end of the ejector rod 240 applies upward pressure to the pressure sensor 230, the alarm 220 receives a signal of the pressure sensor 230 and then starts to give an alarm, and therefore people can find the water level rise in time, and can timely deal with the rise, and the irretrievable result is avoided; the wall body 120 is composed of a buffer layer 121, a water seepage layer 122 and an anti-freezing concrete layer 123, wherein the buffer layer 121 is a honeycomb concrete layer and is in contact with a soil body to buffer the pressure of the soil body, so that the deformation, cracking and even collapse of a retaining wall body caused by the pressure extrusion of the soil body are avoided, the water seepage layer 122 is a pebble layer, the particle size of pebbles in the pebble layer is 3-5mm, the pebble layer does not absorb water and has good penetrating power, water entering the retaining wall body from a supporting soil body can be guided into the ground after being filtered by the pebble layer, the water entering the subsequent anti-freezing concrete layer 123 is reduced, and the anti-freezing concrete layer 123 is built by anti-freezing concrete and mainly avoids the expansion and cracking of the concrete; the one side that permeable layer 122 was kept away from to buffer layer 121 is arcwall face and indent, and the arcwall face of indent can further bear the pressure that the supporting soil body brought, further reduces the supporting soil body and receives the pressure that the frost inflation brought the retaining wall body.

It should be noted that the specific model specifications of the alarm 220 and the pressure sensor 230 need to be determined by type selection according to the actual specification of the device, and the specific type selection calculation method adopts the prior art, so detailed description is omitted; the power supply of the alarm 220 and the pressure sensor 230 and the principle thereof will be clear to a person skilled in the art and will not be described in detail here.

In summary, when the hydraulic engineering retaining wall obtained through the design is used, when the water level rises, the floating block is subjected to the buoyancy of water and then moves upwards, so that the ejector rod can be driven to move upwards in the fixed block, the top end of the ejector rod applies upward pressure to the pressure sensor, the alarm receives a signal of the pressure sensor and then starts to give an alarm, so that people can find the rise of the water level in time and can timely process the rise of the water level, and irretrievable consequences are avoided; the retaining wall for the hydraulic engineering is simple in construction and high in efficiency, not only can the construction cost in the hydraulic engineering be greatly reduced, but also the retaining wall for the hydraulic engineering provided by the embodiment of the invention can be efficiently, stably and appropriately built, so that the retaining wall for the hydraulic engineering has good cost and working condition adaptability advantages when being popularized on a large scale in the engineering.
