Description

Technical Field

[0001] The utility model relates to a greening slope drainage retaining wall structure, belonging to the technical field of retaining wall structures. Background Art

[0002] Slope greening is an emerging ecological slope protection method that can effectively protect exposed slopes. Combined with traditional engineering slope protection, it can effectively restore the ecological vegetation on the slope. During the construction process, in order to prevent the fill or soil from becoming unstable, retaining wall structures are often designed to withstand the pressure of the back soil and ensure the stability of the soil and the slope foot. Retaining walls are often made of impermeable materials such as concrete and rubble concrete.

[0003] In order to avoid the increase in pressure caused by water accumulation behind the retaining wall, drainage pipes are often installed in the retaining wall to ensure that the water behind the retaining wall is removed in time. If there is a lot of water in front of the retaining wall, it will flow back from the inside of the drainage pipe to the back of the retaining wall, thereby causing damage to the green vegetation behind the retaining wall.

In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments can also be implemented by those skilled in the art without these specific details.

[0026] like Figure 1-Figure 5As shown, a green slope drainage retaining wall structure includes a concrete retaining wall 1, the bottom of the concrete retaining wall 1 is fixedly connected to a concrete base 11, an anti-backflow drainage mechanism 2 is provided on the right side of the concrete retaining wall 1, and an auxiliary mechanism 3 is provided on the top and left side of the concrete retaining wall 1. The anti-backflow drainage mechanism 2 includes a drainage pipe 21, the drainage pipe 21 is fixedly connected to the right side of the concrete retaining wall 1, the top of the drainage pipe 21 is fixedly connected to a one-way pipe 22, an inner ring 221 is fixedly installed on the inner wall of the one-way pipe 22, a sliding rod 222 is slidably connected to the inner wall of the inner ring 221, a sealing plate 223 is fixedly installed on the bottom of the sliding rod 222, and the top of the sealing plate 223 is movable with the bottom of the inner ring 221 The one-way tube 22 is connected to the inner wall of the one-way tube 22 with a support plate 224 located below the sealing plate 223. The top of the support plate 224 is fixedly installed with an elastic member 225. The top of the elastic member 225 is fixedly connected to the bottom of the sealing plate 223. When accumulated water seeps into the inner cavity of the one-way tube 22, the gravity of the accumulated water itself can press down the sealing plate 223, and at the same time vertically compress the elastic member 225, so that the water can move downward from the top of the one-way tube 22 for discharge. When there is too much water in front of the concrete retaining wall 1, the initial elastic force of the elastic member 225 prompts the sealing plate 223 to fit tightly against the top of the inner ring 221, thereby sealing the inner cavity of the one-way tube 22 and realizing the function of preventing backflow.

[0027] The top of the one-way tube 22 is fixedly connected to the filter cartridge 23, and the outer wall of the filter cartridge 23 is movably sleeved with a bracket 24, which is detachably connected to the right side of the concrete retaining wall 1. A stainless steel mesh 231 is fixedly installed on the inner wall of the filter cartridge 23, and a support ring 232 is fixedly installed on the inner wall of the filter cartridge 23. The top of the support ring 232 is fixedly connected to the stainless steel cover 233. The inner cavity of the filter cartridge 23 is filled with a gravel filter layer located on the top of the stainless steel mesh 231 and in the inner cavity of the stainless steel cover 233. A geotextile anti-filter cover 234 is fixedly sleeved on the outer wall of the stainless steel cover 233. Through the cooperation of the stainless steel mesh 231, the support ring 232 and the stainless steel cover 233, the sand and gravel can be blocked in the inner cavity of the filter cartridge 23 to form a sand and gravel filter layer. Through the cooperation of the geotextile anti-filter cover 234 and the sand and gravel filter layer, the accumulated water can be filtered to avoid the problem of soil loss with the accumulated water. The design of the bracket 24 can provide a stable support for the filter cartridge 23.

[0028] The cam 314 is fixed on the top of the cam 316, and the cam 315 is fixed on the top of the cam 316. The cam 315 is fixed on the top of the cam 316 to prevent the cam 316 from sliding off. The second locking member 312 is fixed to the upper edge of the support frame 314, and the locking member 312 is fixed to the upper edge of the support frame 314, so that the locking member 312 can be fixed to the support frame 314 to secure the support frame 314 to the upper edge of the support frame 314.

[0029] The working principle of the greening slope drainage retaining wall structure of the present invention is as follows: when erecting, the overall length and angle of the strip tube 312 and the strip rod 313 are adjusted to firmly support the concrete retaining wall 1, and then a specified number of heightening strips 324 are erected on the top of the top support strip 32. When water accumulates behind the concrete retaining wall 1, the accumulated water will seep into the inner cavity of the one-way pipe 22, and the sealing plate 223 can be pressed down by the gravity of the accumulated water itself, and then discharged through the one-way pipe 22, the drainage pipe 21 and the inner cavity of the concrete retaining wall 1. When there is too much water in front of the concrete retaining wall 1, the initial elastic force of the elastic member 225 prompts the sealing plate 223 to fit tightly against the top of the inner ring 221, thereby sealing the inner cavity of the one-way pipe 22 and realizing the function of preventing backflow.
