[0002] As is well known, a retaining wall refers to a structure that supports the soil filling of a roadbed or a hillside soil mass and prevents the filling or soil mass from deforming and becoming unstable. In the cross-section of a retaining wall, the part in direct contact with the supported soil mass is called the wall back; the opposite, open part is called the wall face; the part in direct contact with the foundation is called the base; the top surface of the wall opposite to the base is called the wall top; the front end of the base is called the wall toe; and the rear end of the base is called the wall heel.

[0003] In the case of continuous rainfall or heavy rainfall, in the existing water conservancy retaining wall, due to the lack of through-hole structure in the wall body, there will be a phenomenon of water imbalance between the soil filling inside the retaining wall and the external water and soil, resulting in the simultaneous loss of water and soil inside the retaining wall, thus affecting the stability of the retaining wall. For this reason, we propose a water conservancy retaining wall. Content of the Utility Model

The ventilation holes, water inlet holes and drainage holes are all arranged in a uniform one-word arrangement.

[0006] Preferably, fixing strips are arranged at the edge part near the surface of the wall back, the wall back and the fixing strips are fixedly connected by anti-rust bolts, and a geotextile filter layer is fixedly connected inside the fixing strips.

[0007] Preferably, a buttress is fixedly connected to one side of the wall back, the buttresses are arranged in a triangular shape and evenly arranged, and the buttresses are arranged inside the stone skeleton.

[0008] Preferably, a wall toe is arranged at one end of the foundation main body, a wall heel is arranged at the other end of the foundation main body, and a base is arranged at the bottom of the foundation main body.

[0009] Preferably, the drainage holes are arranged in a slope shape, with the end close to the wall surface being at a lower position and the end close to the wall back being at a higher position.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] The ventilation holes provided help to eliminate the expansion pressure generated by the increased water content of the soil filler inside the stone skeleton, and can reduce the frost heaving pressure of the filler in seasonal freezing areas. The drainage holes provided can prevent surface water from infiltrating and reduce the hydrostatic pressure on the main body of the wall. Through the provided water inlet holes, it is convenient to drain the water accumulated inside the main body of the wall, avoid leakage and cracking, ensure ventilation and dryness inside the retaining wall, and extend the service life.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3 , the present utility model provides a technical solution: a water conservancy retaining wall, including a main body of the foundation 1, a main body of the wall 2 is fixedly connected to one side of the top of the main body of the foundation 1, a wall surface 3 and a wall back 4 are provided on both sides of the main body of the wall 2, a ventilation hole 11 is penetrated and opened above the surface of the main body of the wall 2, a water inlet hole 10 is penetrated and opened in the middle of one side surface of the main body of the wall 2, a drainage hole 9 is penetrated and opened below one side surface of the main body of the wall 2, a stone skeleton 8 is fixedly connected above the main body of the foundation 1, the stone skeleton 8 is fixedly connected with the wall back 4, and the ventilation hole 11, the water inlet hole 10 and the drainage hole 9 are all arranged in a uniform arrangement in a straight line.

[0018] Specifically, a fixing strip 13 is provided at a position near the edge on the surface of the wall back 4. The wall back 4 and the fixing strip 13 are fixedly connected by anti-rust bolts 14. A geotextile filter layer 15 is fixedly connected to the inner side of the fixing strip 13. A buttress 12 is fixedly connected to one side of the wall back 4. The buttresses 12 are arranged in a triangular shape and evenly installed. The buttresses 12 are arranged inside the stone skeleton 8. A wall toe 5 is provided at one end of the foundation main body 1, and a wall heel 7 is provided at the other end of the foundation main body 1. A base 6 is provided at the bottom of the foundation main body 1. The drain holes 9 are arranged in a slope shape. The end of the drain hole 9 close to the wall surface 3 is at a low position, and the end of the drain hole 9 close to the wall back 4 is at a high position.

[0019] In this embodiment, during specific use, through the opening formed by the stone skeleton 8 and the upper end of the wall body main body 2, soil materials can be filled into the inner side of the stone skeleton 8, thereby increasing the overall weight of the device and improving the overall stability. The ventilation holes 11 arranged in the upper row of the wall body main body 2 help to eliminate the expansion pressure generated by the increase in the water content of the soil filler inside the stone skeleton 8, and can also reduce the frost heaving pressure of the filler in seasonal freezing areas. By arranging the drain holes 9, surface water infiltration can be prevented, the hydrostatic pressure on the wall body main body 2 can be reduced, and at the same time, it also helps to eliminate the expansion pressure and frost heaving pressure generated by the increase in the water content, thereby maintaining the stability of the soil.
