Abstract
Description
Technical Field
[0001] The present application relates to the technical field of water conservancy projects, and in particular to a retaining wall component for water conservancy projects. Background Art
[0002] At present, retaining walls, also often called retaining walls, are one of the indispensable structural elements in water conservancy projects. They are mainly used to support soil, prevent collapse and control soil erosion, ensuring the stability and safety of the project.
[0003] As an important part of water conservancy projects, the design of retaining walls should not only consider supporting and stabilizing the soil, but also effectively manage the moisture behind the wall. As an important part of retaining wall design, drainage holes are mainly used to drain water behind the wall and reduce the impact of static water pressure and dynamic water pressure on the wall, thereby ensuring the stability of the soil and the safety of the wall. In the actual construction process, drainage holes are usually generated by reserving holes in the wall or installing special drainage pipes.
[0004] Over time, the drainage holes will become clogged due to the migration of surrounding soil particles, vegetation growth or the accumulation of other foreign matter. Once the drainage holes are clogged, their drainage function will be affected, resulting in increased water pressure behind the retaining wall, which will increase the risk of instability of the retaining wall. Utility Model Content
[0005] In order to maintain the patency of the drainage holes and improve the convenience of dredging the drainage holes, the present application provides a retaining wall component for water conservancy projects.
[0006] The present application provides a retaining wall component for a water conservancy project using the following technical solution:
[0007] A retaining wall component for a water conservancy project includes a retaining wall, a first drain pipe and a filter layer are fixed on the retaining wall, the filter layer is located on the side wall of the retaining wall facing the soil, the first drain pipe runs through the retaining wall, a cleaning assembly is arranged on the first drain pipe, the cleaning assembly includes an inner pipe, a ring cutting rod and a cutter head, the inner pipe is rotatably arranged inside the first drain pipe and the center line coincides with the center line of the first drain pipe, the inner pipe rotates relative to the first drain pipe, the sum of the lengths of the inner pipe, the ring cutting rod and the cutter head is not less than the length of the first drain pipe, one end of the ring cutting rod is fixedly connected to the end of the inner pipe penetrating into the first drain pipe, the other end of the ring cutting rod is fixed to the cutter head, and the cutter head is close to the inner wall of the first drain pipe.
[0008] By adopting the above technical solution, the water in the soil on one side of the retaining wall is discharged through the first drain pipe. When the inside of the first drain pipe needs to be dredged, the inner pipe is rotated, and the inner pipe drives the ring cutting rod and the cutter head to rotate. The cutter head cuts off the roots of vegetation growing at the end of the first drain pipe, and the ring cutting rod cleans the inner wall of the first drain pipe. The cleaned debris will flow out with the subsequent water flow, so that the inside of the first drain pipe remains unobstructed, and the operation is simple and convenient.

[0010] By adopting the above technical solution, a distance is created between the outer wall of the inner tube and the inner wall of the first drain pipe, thereby reducing the friction generated when the inner tube rotates relative to the first drain pipe, allowing the inner tube to rotate more conveniently. The annular groove and the retaining ring are arranged so that when the first drain pipe drains water, water cannot flow into between the inner tube and the first drain pipe. The edge plate and the ring eaves are arranged to connect the inner tube while the exposed connection state facilitates the cleaning of the edge plate and the ring eaves, thereby maintaining the smoothness of the inner tube rotation.
[0011] Optionally, a water inlet pipe is arranged between the first drain pipe and the inner pipe. The water inlet pipe penetrates the edge plate and goes deep into the first drain pipe to be fixedly connected with the ring cutting rod. A drainage hole is opened in the ring cutting rod. One end of the drainage hole is connected to the water inlet pipe, and the other end extends to the cutter head.
[0012] By adopting the above technical solution, high-pressure water is introduced into the water inlet pipe, and the pressurized water is sprayed out from the cutter head through the water inlet pipe and the drainage hole. On the one hand, it cooperates with the cutter head to cut off the roots of plants at the end of the first drainage pipe, and on the other hand, it is convenient to flush the cut roots and other debris out of the first drainage pipe.
[0013] Optionally, the drainage hole is bifurcated at the cutter head, and the bifurcated direction is the pre-rotation direction of the cutter head relative to the first drainage pipe.

[0016] By adopting the above technical solution, the inner support rod provides a fixed position for the positioning ring, and the positioning ring provides a force point for the rotation of the inner tube, which is convenient for the operator to rotate the inner tube with the help of tools. The operator only needs to fix the positioning ring with the tool.
[0017] Optionally, a second drain pipe is fixed on the retaining wall, the first drain pipe is located above the second drain pipe and is inclined downward in the direction away from the soil, and the second drain pipe is horizontally arranged; the cleaning components are correspondingly arranged in two groups, one group is located in the first drain pipe, and the other group is located in the second drain pipe.
[0018] By adopting the above technical solution, the existence of the first drain pipe reduces the drainage pressure of the second drain pipe, and the accumulated water can be discharged through the first drain pipe during the infiltration process. The existence of the second drain pipe enables the water in the soil to be discharged as much as possible.
[0019] Optionally, the filter layer is concave at the first drain pipe port and the second drain pipe port, that is, there is a distance between the filter layer and the end of the first drain pipe and the end of the second drain pipe.
[0020] By adopting the above technical solution, the distance between the end of the first drain pipe and the end of the second drain pipe and the filter layer provides space for the spraying of the high-pressure water gun and the rotation of the blade head, while also reducing the possibility of plant roots growing into the first drain pipe and the second drain pipe.
