Description
Technical Field
[0001] The utility model belongs to the technical field of retaining walls, and in particular relates to an inland river retaining wall. Background Art
[0002] Generally speaking, in order to reduce the collapse of soil on both sides of the river channel, retaining walls are built in the river channel during the excavation and construction of the river channel to effectively support both sides of the river channel and reduce the occurrence of collapse.
[0003] At present, vertical retaining walls are a common river retaining wall in life. Vertical retaining walls are vertical walls composed of stacked bricks. This type of retaining wall can reduce soil erosion on both sides of the river, thereby playing a protective role on both sides of the river.
[0004] During long-term use, the existing vertical retaining walls are eroded by the water flow of the river on both sides, and the silt on both sides of the river is easily washed into the river. How to improve the waterproofness of the retaining wall is a technical problem that technical personnel in this field need to solve. Utility Model Content
[0005] The utility model aims to solve the above-mentioned technical problems existing in the prior art and provides an inland river retaining wall. By arranging bored concrete piles on both sides of the river channel and arranging water-stop curtains between the bored concrete piles, the river water on both sides of the river channel scours the reinforced concrete retaining wall. The setting of the water-stop curtains prevents the soil around the bored concrete piles from flowing into the river channel through the pores of the reinforced concrete retaining wall, thereby improving the waterproof performance of the retaining wall and the stability of the bored concrete piles. It can effectively support both sides of the river channel and reduce the occurrence of collapse.
[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

The utility model arranges bored concrete piles on both sides of the river channel, and arranges water-stop curtains between the bored concrete piles, so that the river water on both sides of the river channel scours the reinforced concrete retaining wall, and the arrangement of the water-stop curtains prevents the soil around the bored concrete piles from flowing into the river channel through the pores of the reinforced concrete retaining wall, thereby improving the waterproof performance of the retaining wall, and at the same time improving the stability of the bored concrete piles, and can effectively support both sides of the river channel and reduce the occurrence of collapse.
[0008] Furthermore, the bottom of the river channel is paved with geotextiles, the top of the geotextiles is paved with a crushed stone cushion layer, the top of the crushed stone cushion layer is paved with a second plain concrete cushion layer, and the top of the second plain concrete cushion layer is paved with a concrete bottom protection layer. The bottom of the river channel is poured to maintain the flatness and stability of the bottom of the river channel, and the hardness of the foundation is also improved to withstand the impact and erosion of the water flow on the bottom, thereby maintaining the stability of the river channel.
[0009] Furthermore, reinforced concrete facings are installed on both sides of the river. The installation of reinforced concrete facings increases the anti-scouring ability of the retaining wall, which can reduce soil erosion on both sides of the river, thus playing a protective role on both sides of the river.
[0010] Furthermore, a coarse stone paving is laid on the top of the reinforced concrete paving near the river channel. The coarse stone paving has a long service life, prevents soil erosion, and also has a landscape function.
[0011] Furthermore, double-layer bidirectional mesh reinforcement is laid in the reinforced concrete face, which increases the structural strength of the reinforced concrete face and improves the anti-scouring capability of the retaining wall.

They not only have excellent anti-corrosion properties, but also have strong shape and low water absorption, especially earthquake resistance, easy nailing, and easy sawing. Pine piles have high compressive and bending bearing capacity when subjected to water and soil pressure, and can effectively support the weight of the retaining wall and ensure the stability of the retaining wall.
[0013] Furthermore, the pinewood piles are arranged in a rectangular shape, so that the retaining wall is evenly stressed and the stability of the retaining wall is improved.
[0014] Furthermore, drainage pipes are evenly distributed in the reinforced concrete retaining wall, so that water accumulated on the back of the wall and water seepage from the soil can be discharged in time, thus ensuring the stability of the retaining wall.
[0015] Furthermore, one end of the drainage pipe is connected to a sand filter, and one end of the drainage pipe is wrapped with a geotextile. The drainage pipe and the outer side of the sand filter are tied and fixed by the geotextile. The setting of the sand filter prevents soil particles from leaking outward. It can effectively prevent the loss and excretion of soil particles, maintain the stability of the retaining wall, and protect the surrounding environment.
[0016] Furthermore, the diameter of the sand filter is greater than or equal to 40 cm, and the sand particle size in the sand filter is between 0.5 mm and 2 mm, which can effectively prevent the loss and discharge of soil particles, maintain the stability of the retaining wall, and protect the surrounding environment.
