[0002] In water conservancy projects, reasonable drainage measures are crucial to the stability of bank protection structures. The water in the slope soil must be discharged smoothly to reduce the water and soil pressure of the bank protection structure and avoid excessive structural deformation, cracking, instability and other phenomena. In order to ensure that the water in the slope soil can be discharged smoothly, the traditional bank protection structure pre-buries drainage pipes and anti-filter bags in the slope soil, which requires large-scale excavation and backfilling of the slope soil, resulting in increased engineering volume, extended construction period, and increased engineering costs. For the pile structure, it violates the original intention of reducing earth excavation. For the retaining wall structure, the construction is difficult and the procedures are cumbersome. In addition, the construction quality is difficult to guarantee, it is easy to be blocked, the drainage effect is poor, and there are safety hazards. Utility Model Content

[0006] A prefabricated drainage pipe is inserted into the insertion hole of the bank protection structure, and the prefabricated drainage pipe penetrates into the slope soil body on one side of the bank protection structure;
[0007] The first end of the prefabricated drainage pipe is a water outlet, which corresponds to the first end position of the insertion hole. The second end of the prefabricated drainage pipe is a pointed part for facilitating the insertion of the prefabricated drainage pipe into the slope soil. The prefabricated drainage pipe body is provided with a plurality of water inlets.
[0008] A retaining ring is formed at the first end of the prefabricated drainage pipe, and the outer diameter of the retaining ring is larger than the diameter of the insertion hole.
[0009] The retaining ring is in close contact with the outer side surface of the bank protection structure, and a water-stopping sealant is filled between the retaining ring and the bank protection structure.

[0024] Embodiment 1: This embodiment is a slope revetment combined with a prefabricated drainage structure, having a revetment structure arranged next to the slope soil body. The revetment structure is a pile body constructed using non-excavation technology such as prefabricated concrete piles and cast-in-place reinforced concrete pipe piles.
[0025] In this example, a number of insertion holes are evenly distributed on the revetment structure in a plum blossom-shaped arrangement. The insertion holes penetrate the revetment structure, and the first end of the insertion hole is lower than the second end thereof, and the slope is inclined downward between 5% and 10%, wherein the first end is the end of the insertion hole away from the slope soil, and the second end of the insertion hole is close to the slope soil.
[0026] In this embodiment, a prefabricated drainage pipe is inserted into the insertion hole of the bank protection structure, and the prefabricated drainage pipe penetrates into the slope soil on one side of the bank protection structure.
[0027] In this example, the first end of the prefabricated drainage pipe is the water outlet and a retaining ring is formed at the first end; at least two rows of water inlets are provided on the pipe body of the prefabricated drainage pipe, each row of water inlets is arranged parallel to the axis of the prefabricated drainage pipe and each row has multiple water inlets; the second end of the prefabricated drainage pipe is a pointed head for facilitating the insertion of the prefabricated drainage pipe into the slope soil, and the pointed head adopts a conical solid structure and is integrally formed with the pipe body.
[0028] In this embodiment, the length of the prefabricated drainage pipe is between 1 and 3 meters, and the outer diameter is adapted to the diameter of the insertion hole, generally between 5 and 20 cm.
[0029] In this embodiment, the outer diameter of the retaining ring is larger than the diameter of the insertion hole. The retaining ring adopts a thin-walled structure and is integrally formed with the pipe body, which plays a role in fixing the drain pipe and facilitates the later replacement operation. When the prefabricated drain pipe is inserted into the slope soil through the insertion hole, the retaining ring is close to the outer side of the bank protection structure, and a water-stopping sealant with a thickness of 1 to 2 cm is filled between the retaining ring and the bank protection structure, which plays a role in bidirectional sealing and water-stopping, preventing the moisture of the soil behind the bank protection structure from flowing out from the gap between the drain pipe and the pile hole, and also preventing the water in the water body in front of the bank protection structure from infiltrating into the back of the bank protection structure.
[0030] In this embodiment, a filter module is filled in the prefabricated drainage pipe, and the filter module has a filter bag and graded sand and gravel filled in the filter bag. In this embodiment, the first end of the pipe body retains 5 to 10 cm without a water inlet, and no filter bag and graded sand and gravel are placed. The outer diameter of the filter bag is consistent with the inner diameter of the pipe body, and the mesh size of the filter bag should be smaller than the minimum particle size of the graded sand and gravel. The particle diameter and mix ratio of the graded sand and gravel are calculated and determined according to the different slope soil materials, and are densely filled inside the pipe body.
[0031] Embodiment 2: The structure of this embodiment is basically the same as that of Embodiment 1, the only difference being that the bank protection structure in this embodiment is a retaining wall constructed using excavation technology, such as gravity type, counterweight type, cantilever type, buttress type, etc.
[0032] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
