Abstract
Description
Technical Field
[0001] This utility model relates to the field of slope protection retaining wall technology, and in particular to a pollution-proof slope protection retaining wall structure. Background Technology
[0002] With the progress of urban development, especially in mountainous cities, a large number of slope protection retaining walls are generated during the development and construction process. In order to maintain the structural stability of the retaining walls and alleviate the pressure of surface water or groundwater on the soil and rock layers in the protected area, according to the relevant specifications for slope protection engineering, drainage holes must be set at certain intervals on the slope protection retaining walls.
[0003] The drainage holes on the slope retaining wall ensure the mechanical stability of the retaining wall, but organized drainage has not been considered. When the soil and rock strata in the area have a large amount of water, the drainage holes will spray water, polluting the surrounding environment. At the same time, the water will flow down the wall during drainage, leaving watermarks and stains on the wall. Over time, weeds and moss will even grow around the wall, which will also cause certain damage to the structural stability of the retaining wall. Utility Model Content
[0004] The purpose of this utility model is to provide a pollution-proof slope support retaining wall structure, which aims to solve the problem that when the water volume in the soil and rock strata of the existing slope support retaining wall is large, the drainage holes on the slope support retaining wall will spray water, polluting the surrounding environment. At the same time, when the water is drained, the water will flow down the wall and leave water marks and stains on the wall, which will endanger the structural stability of the slope support retaining wall.
[0005] To achieve the above objectives, this utility model provides a pollution-proof slope support retaining wall structure, including a retaining wall body and pollution-proof components; the pollution-proof components include multiple transverse drainage pipes, longitudinal drainage pipes, drainage ditches, a wire mesh layer, a cement mortar leveling layer, and a finishing layer;
[0006] The retaining wall body has multiple drainage grooves inside; multiple transverse drainage pipes are respectively installed inside the retaining wall body; the longitudinal drainage pipes are fixedly connected to and communicate with the multiple transverse drainage pipes, and are located in the drainage grooves; the drainage ditch is installed on the side of the retaining wall body; the wire mesh layer is installed on the side of the retaining wall body; the cement mortar leveling layer is installed on the side of the wire mesh layer away from the retaining wall body; the finishing layer is installed on the side of the cement mortar leveling layer away from the wire mesh layer.
[0007] The pollution prevention component also includes a louvered vent cap; the louvered vent cap is fixedly installed on the side of the retaining wall body and is connected to the longitudinal drainage pipe.
[0008] The anti-pollution component also includes a pipe support; the pipe support is disposed between the retaining wall body and the longitudinal drainage pipe.
[0009] The retaining wall body has an inspection port located on the side of the retaining wall body and is connected to the longitudinal drainage pipe.
[0010] The anti-pollution component also includes multiple gravel filter bags, which are fixedly connected to multiple horizontal drain pipes and located on the sides of the multiple horizontal drain pipes.
[0011] This utility model discloses a pollution-proof slope support retaining wall structure. During the pouring of the retaining wall main body, transverse drainage pipes are pre-embedded, and drainage grooves are reserved within the retaining wall main body to accommodate longitudinal drainage pipes. After the longitudinal drainage pipes are installed in the drainage grooves, cement mortar is used to fill the gaps between the longitudinal drainage pipes and the drainage grooves, forming a cement mortar leveling layer. The cement mortar can more firmly fix the pipes to the wall. Then, a wire mesh layer is laid on the surface of the retaining wall main body. To ensure a clean and aesthetically pleasing final facade, the cement mortar leveling layer is used for overall leveling. Finally, real stone paint is sprayed onto the wall surface for finishing, forming the finishing layer, which serves to waterproof, reinforce, and beautify the structure. By placing the longitudinal drainage pipes in the pre-reserved drainage grooves of the retaining wall, the longitudinal drainage pipes are prevented from protruding outside the wall. The surface water or groundwater in the soil and rock strata of the area blocked by the main body of the retaining wall is discharged in an organized manner through the transverse drainage pipes and the longitudinal drainage pipes into the drainage ditch at the bottom of the main body of the retaining wall. This avoids jet-like drainage that pollutes the surrounding environment, isolates sewage from contact with the wall surface, prevents sewage from eroding the wall, inhibits the growth of weeds and moss, and maintains the structural stability of the retaining wall. The longitudinal drainage pipes are encased in the main body of the retaining wall through a cement mortar leveling layer and a finishing layer, forming an integral part of the retaining wall and presenting a clean and beautiful facade, thereby beautifying the environment. This solves the problem that when the water volume in the soil and rock strata of the existing slope protection retaining wall is large, the drainage holes on the slope protection retaining wall will spray water, polluting the surrounding environment. At the same time, when the water is drained, it will flow down the wall and leave watermarks and stains on the wall, which will endanger the structural stability of the slope protection retaining wall.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

Figure 3 yes Figure 1 A magnified view of detail A. Figure 4 This is a structural diagram of the retaining wall body of this utility model, which is a gravity retaining wall.

[0021] This utility model provides a pollution-resistant slope support retaining wall structure, including a retaining wall body 101 and pollution-resistant components. The pollution-resistant components include multiple transverse drainage pipes 102, longitudinal drainage pipes 103, drainage ditches 104, a wire mesh layer 105, a cement mortar leveling layer 106, a finishing layer 107, louvered ventilation caps 109, pipe supports 110, and multiple gravel filter bags 112. The aforementioned solution solves the problem that when the water volume in the regional soil and rock strata is large, the drainage holes on the existing slope support retaining wall will spray water, polluting the surrounding environment. At the same time, when draining water, it will flow down the wall, leaving watermarks and stains on the wall, which will endanger the structural stability of the slope support retaining wall.
[0022] In this specific embodiment, the retaining wall body 101 is provided with a plurality of drainage grooves 108 inside; a plurality of transverse drainage pipes 102 are respectively disposed inside the retaining wall body 101; the longitudinal drainage pipes 103 are respectively fixedly connected to and communicate with the plurality of transverse drainage pipes 102, and are located within the drainage grooves 108; the drainage ditch 104 is disposed on the side of the retaining wall body 101; the wire mesh layer 105 is disposed on the side of the retaining wall body 101; the cement mortar leveling layer 106 is disposed on the side of the wire mesh layer 105 away from the retaining wall body 101; and the finishing layer 107 is disposed on the side of the cement mortar leveling layer 106 away from the wire mesh layer 105. When the retaining wall body 101 is poured, the horizontal drainage pipe 102 is pre-embedded, and a drainage groove 108 is reserved in the retaining wall body 101 to accommodate the vertical drainage pipe 103. After the vertical drainage pipe 103 is installed in the drainage groove 108, the gap between the vertical drainage pipe 103 and the drainage groove 108 is filled with cement mortar to form the cement mortar leveling layer 106. The cement mortar can fix the pipe to the wall more firmly. Then, the wire mesh layer 105 is laid on the surface of the retaining wall body 101. In order to ensure that the final exterior of the retaining wall is neat and beautiful, the cement mortar leveling layer 106 is used for overall leveling. Then, real stone paint is sprayed on the wall surface for finishing, forming the finishing layer 107, which plays the role of waterproofing, reinforcement and beautification. By placing the longitudinal drainage pipe 103 in the pre-reserved drainage groove 108 of the retaining wall, the longitudinal drainage pipe 103 is prevented from protruding outside the wall. The transverse drainage pipe 102 and the longitudinal drainage pipe 103 systematically discharge surface water or groundwater from the soil and rock strata in the area blocked by the retaining wall body 101 into the drainage ditch 104 at the bottom of the retaining wall body 101. This avoids spraying water pollution of the surrounding environment, isolates sewage from contact with the wall surface, prevents sewage erosion of the wall, inhibits the growth of weeds and moss, and maintains the retaining wall. The structure is stable. The longitudinal drainage pipe 103 is encapsulated in the retaining wall body 101 through the cement mortar leveling layer 106 and the finishing layer 107, forming an integral part with the retaining wall and presenting a neat and beautiful facade, thereby beautifying the environment. This solves the problem that when the water volume in the soil and rock strata of the existing slope protection retaining wall is large, the drainage holes on the slope protection retaining wall will spray water, polluting the surrounding environment. At the same time, when draining water, the water will flow down the wall, leaving watermarks and stains on the wall, which will endanger the structural stability of the slope protection retaining wall.
[0023] The louvered vent cap 109 is fixedly installed on the side of the retaining wall body 101 and is connected to the longitudinal drain pipe 103. The louvered vent cap 109 is installed to ensure smooth drainage of water in the longitudinal drain pipe 103. This is because sewage will generate gas in the closed pipe, or a vacuum will occur when there is a large flow of water. Due to the pressure imbalance, the water cannot flow down. The louvered vent cap 109 is used to make the air pressure in the longitudinal drain pipe 103 consistent with the external atmospheric pressure, thereby allowing the water to flow out smoothly.
[0024] Secondly, the pipe support 110 is disposed between the retaining wall body 101 and the longitudinal drainage pipe 103. The disposed pipe support 110 can bear the weight of the longitudinal drainage pipe 103, preventing the longitudinal drainage pipe 103 from sinking or deforming due to its own weight, and ensuring that the longitudinal drainage pipe 103 maintains a stable position inside the retaining wall.
[0025] Meanwhile, the retaining wall body 101 has an inspection port 111, which is located on the side of the retaining wall body 101 and is connected to the longitudinal drainage pipe 103. The inspection port 111 is used to clean out mud, sand, or other foreign objects from the longitudinal drainage pipe 103 to prevent blockage and drainage problems. When it is not necessary to clean the foreign objects from the longitudinal drainage pipe 103, the inspection port is sealed with a sealing cover or other sealing material.
[0026] In addition, multiple gravel filter bags 112 are fixedly connected to multiple transverse drainage pipes 102 and are located on the sides of the transverse drainage pipes 102 respectively. The gravel filter bags 112 are used for soil filtration and drainage, which can prevent the soil in the area blocked by the retaining wall body 101 from being separated by seepage water, while ensuring that the water in the soil can enter the transverse drainage pipes 102 and be discharged.
[0027] When using this utility model, during the pouring of the retaining wall body 101, the horizontal drainage pipe 102 is pre-embedded, and a drainage groove 108 is reserved in the retaining wall body 101 to accommodate the vertical drainage pipe 103. After the vertical drainage pipe 103 is installed in the drainage groove 108, the gap between the vertical drainage pipe 103 and the drainage groove 108 needs to be filled with cement mortar to form the cement mortar leveling layer 106. The cement mortar can more firmly fix the pipe to the wall. Then, the wire mesh layer 105 is laid on the surface of the retaining wall body 101. In order to ensure that the final exterior of the retaining wall is neat and beautiful, the cement mortar leveling layer 106 is used for overall leveling. Then, real stone paint is sprayed on the wall surface for finishing, forming the finishing layer 107, which plays the role of waterproofing, reinforcement and beautification. By placing the longitudinal drainage pipe 103 in the pre-reserved drainage groove 108 of the retaining wall, the longitudinal drainage pipe 103 is prevented from protruding outside the wall. The transverse drainage pipe 102 and the longitudinal drainage pipe 103 systematically discharge surface water or groundwater from the soil and rock strata in the area blocked by the retaining wall body 101 into the drainage ditch 104 at the bottom of the retaining wall body 101. This avoids spraying water pollution of the surrounding environment, isolates sewage from contact with the wall surface, prevents sewage erosion of the wall, inhibits the growth of weeds and moss, and maintains the retaining wall. The structure is stable. The longitudinal drainage pipe 103 is encapsulated within the retaining wall body 101 through a cement mortar leveling layer 106 and a finishing layer 107, forming an integral part of the retaining wall and presenting a clean and aesthetically pleasing facade. This beautifies the environment and solves the problem that existing slope protection retaining walls, when there is a large amount of water in the regional soil and rock strata, will have jet-like drainage from the drainage holes, polluting the surrounding environment. Simultaneously, during drainage, water will flow down the wall, leaving watermarks and stains, which can damage the structural stability of the slope protection retaining wall. The retaining wall body 101 can be a pile-slab retaining wall or a gravity retaining wall; the installation method of the anti-pollution component remains unchanged, and it can be installed on both types of retaining walls. Figure 1 and Figure 2 This is a schematic diagram of the retaining wall body 101 as a pile-slab retaining wall. Horizontal drainage pipes 102 are installed on the pile-slab retaining wall panel with a horizontal spacing not greater than the spacing between the anti-slip piles 113 on the pile-slab retaining wall, arranged in a matrix pattern with a vertical spacing of 2m, and an outward inclination of 5%. Figure 3 and Figure 4 This is a schematic diagram of the main body 101 of the retaining wall as a gravity retaining wall. The gravity retaining wall body is provided with horizontal drainage pipes 102 arranged in a matrix at 2m intervals horizontally and vertically, with an outward inclination of 5%. The distance between the lowest horizontal drainage pipe 102 and the drainage ditch 104 is 300mm.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
