Technical Field
[0001] The utility model belongs to the field of retaining walls, and in particular relates to an anti-seepage retaining wall structure. Background Art
[0002] A retaining wall refers to a structure that supports roadbed fill or hillside soil and prevents the fill or soil from deforming and becoming unstable. In the cross section of the retaining wall, the part that is in direct contact with the supported soil is called the back of the wall; the part facing the air opposite to the back of the wall is called the wall surface.
[0003] Because the back of the wall is in contact with the soil, on rainy days, the soil is rich in moisture. Under the action of gravity, the moisture on the top of the slope will penetrate downward, making the soil on the back of the wall sufficient in moisture. The retaining wall soaked in water for a long time will affect the stability of the wall structure and reduce the service life of the wall. If not handled in time, water will penetrate to the bottom of the retaining wall, causing the roadbed to be hollowed out, causing the road surface to become muddy, sink, break, crack and misalign, affecting the use of the road.

DETAILED DESCRIPTION
[0023] The utility model is described in detail below in conjunction with the accompanying drawings.
[0024] like Figure 1-5 As shown, an anti-seepage retaining wall structure includes a wall body 1, a plurality of filter units 16 and a collection box 5 are arranged on the back side of the wall body 1, the filter unit 16 is connected to the collection box 5 through a water pipe 4, a drainage pipe 6 is connected to the collection box 5, and the drainage pipe 6 runs through the wall body 1 and leads to a drainage ditch 17 on the road surface. A filter net is arranged at the input end of the water pipe 4.
[0025] The filtering unit 16 includes an L-shaped mounting plate 3 and a first net box 7, a second net box 9, and a third net box 10 which are sequentially mounted from the outside to the inside. The first net box 7, the second net box 9, and the third net box 10 are filled with different fillers, and the particle sizes of the fillers in the first net box 7, the second net box 9, and the third net box 10 decrease sequentially. The first net box 7, the second net box 9, and the third net box 10 are all U-shaped structures. The opening sides of the first net box 7, the second net box 9, and the third net box 10 are all connected to the side plate of the L-shaped mounting plate 3, and the bottoms of the first net box 7, the second net box 9, and the third net box 10 are all connected to the bottom plate of the L-shaped mounting plate 3; the water pipe 4 passes through the first net box 7, the second net box 9, and the third net box 10 and is connected to the inner space of the third net box 10.
[0026] The side plates of the L-shaped mounting plate 3 are mounted on the wall 1 , and the bottom plate of the L-shaped mounting plate 3 is mounted on the collection box 5 .
[0027] There are multiple collecting boxes 5 , and each collecting box 5 is provided with two filtering units 16 .
[0028] The first net box 7 is filled with gravel, the second net box 9 is filled with slag, and the third net box 10 is filled with ceramsite.
[0029] A waterproof layer 2 is provided on the back side of the wall 1 .
[0030] A submersible pump 14 is provided in the collecting box 5 , and an output end of the submersible pump 14 is connected to the drain pipe 6 .
[0031] A water level sensor 11 is provided in the inner space of the third net box 10 , and the water level sensor 11 is connected to a submersible pump 14 .
[0032] It also includes a cleaning mechanism, which includes a bottom support 13, a top cover 8 and a lifting rod 12. The lifting rod 12 is connected between the bottom support 13 and the top cover 8. The bottom support 13 is arranged in contact with the side plate of the L-shaped mounting plate 3 and the inner side of the third net box 10. The bottom support 13 is placed on the bottom plate of the L-shaped mounting plate 3. The position of the bottom support 13 is lower than the position of the drain pipe 6. The top cover 8 is buckled and sealed at the opening formed by the upper end of the side plate of the L-shaped mounting plate 3 and the upper end of the third net box 10. Rubber pads are arranged around the bottom support 13 to make the bottom support 13 better fit the mounting plate 3 and the third net box 10. The side of the lifting rod 12 is provided with anti-slip ridges to facilitate the lifting operation of the staff. A handle ring 15 is provided on the upper surface of the top cover 8.
[0033] On rainy days, the water on the top of the slope penetrates downward, making the soil on the back of the wall 1 sufficiently hydrated. The water in the soil is infiltrated through the gravel inside the first net box 7, the slag inside the second net box 9, and the ceramsite inside the third net box 10, so that the water enters the inner space of the third net box 10 and is collected into the collection box 5 through the water pipe 4, thereby preventing the water in the soil from damaging the wall 1. When the collection box 5 is full of water, the water in the inner space of the third net box 10 will no longer enter the collection box 5 through the water pipe 4. The water level in the inner space of the third net box 10 rises. When the water level reaches the position of the water level sensor 11, the water level sensor 11 sends a signal to the submersible pump 14, and the submersible pump 14 starts to discharge the water in the collection box 5 through the drainage pipe 6 to the drainage ditch 17 on the road surface. Then the water in the inner space of the third net box 10 continues to enter the collection box 5 through the water pipe 4.
[0034] After a period of use, impurities in the inner space of the third net box 10 are deposited on the bottom bracket 13, and maintenance and cleaning are required. The staff pulls the lifting ring 15 to lift the top cover 8, the lifting rod 12 and the bottom bracket 13, and then pulls out the bottom bracket 13 by holding the lifting rod 12 to clean out the impurities deposited on the bottom bracket 13. During the lifting process of the bottom bracket 13, impurities on the L-shaped mounting plate and the side wall of the third net box 10 can also be scraped off. After cleaning, the bottom bracket 13 is put back and the top cover 8 is covered.
