[0025] like Figure 1 and Figure 2As shown, a retaining wall that is easy to drain includes a base plate 1 and a wall body 8. The base plate 1 is made of reinforced concrete, and a gravel layer 2 is arranged at the bottom end of the base plate 1, a rammed earth layer 3 is arranged at the bottom of the gravel layer 2, and soil 4 is arranged at the bottom of the rammed earth layer 3. A pile hole 5 is opened on the inner side of the soil 4, and a prefabricated foundation pile 6 is arranged inside the pile hole 5. The prefabricated foundation pile 6 is made of reinforced concrete, and the outer wall of the prefabricated foundation pile 6 is provided with an annular convex pattern 7, and there are multiple annular convex patterns 7. The wall body 8 is fixed to the top of the base plate 1. When constructing the device, the construction personnel can first divert the river channel, and then use silt solidification equipment to solidify the soil 4 on the river bank. After solidification, the soil 4 is compacted to form a rammed earth layer 3, and then pile holes 5 are punched in the rammed earth layer 3 and the soil 4, and the prefabricated foundation pile 6 is buried. The height of the prefabricated foundation pile 6 is higher than the hole of the pile hole 5 by a certain distance, and then the gap between the prefabricated foundation pile 6 and the pile hole 5 is filled. Cement mortar or backfill soil is added, and then gravel is used to lay a gravel layer 2. The surface of the gravel layer 2 is basically level with the top height of the precast foundation pile 6. After the laying is completed, the construction personnel can use steel bars to weave a grid on the top of the gravel layer 2 and the precast foundation pile 6, and use concrete to cast a base plate 1, and finally build a wall 8 on the top of the base plate 1. The retaining wall constructed in this way has a rammed earth layer 3, so the soil 4 and the gravel layer 2 themselves are not easily compressed and caused to settle. In addition, the outer surface of the precast foundation pile 6 is provided with annular convex patterns 7, so the friction between it and the soil 4, the rammed earth layer 3, and the gravel layer 2 is very large, which can effectively disperse the pressure of the building on the ground into the soil layer and deep underground, further reducing the possibility of settlement of the retaining wall. Through the above structure, the retaining wall can be effectively prevented from settling, breaking and even collapse, which is beneficial to improving the service life of the device.

[0026] like Figure 1 and Figure 3As shown, the cross-section of the wall 8 is stepped, and a hydrophobic wall panel 9 is arranged on the outer wall of one side of the wall 8. The hydrophobic wall panel 9 is made of modified permeable concrete, and the hydrophobic wall panel 9 is fixed to the wall 8 by inlaying. A surface drainage pipe 10 is arranged on the top of the inner part of the wall 8, and an underground drainage pipe 11 is arranged on the bottom of the inner part of the wall 8. A plurality of gabion cages 12 are arranged on the top of the outer wall of the wall 8 away from the hydrophobic wall panel 9, and stones 13 are stacked inside the gabion cages 12. A safety protection component 14 is arranged on the top of the wall 8, and the safety protection component 14 includes a guardrail 1401 and a warning sign 1402. A warning sign 1402 is fixed on one side of the guardrail 1401. The guardrail 1401 can effectively prevent pedestrians from accidentally falling into the water, and the warning sign 1402 can effectively prevent pedestrians from accidentally falling into the water. Warning words such as "Dangerous water depth, no climbing over" can be marked on the sign 1402, thereby fulfilling the warning obligation to prevent people from climbing over the guardrail 1401 without permission and causing drowning accidents, and can also reduce the responsibility borne by the management after people drown from climbing over the guardrail 1401 without permission. The wall 8 is in a stepped shape, so the gabion cage 12 placed on the wall 8 is also in a stepped shape, which not only reduces the possibility of people slipping, but also allows people to climb ashore along the gabion cage 12 even if they fall into the water, avoiding the situation where the shore slope is steep and they cannot go ashore, thereby further reducing the possibility of people drowning. Through the above structure, the retaining wall can reduce the probability of people drowning, and can also facilitate the drowning people to escape ashore, which is beneficial to improving the safety of the device.

[0027] In summary: when using the retaining wall that is easy to drain, firstly, the surface drainage pipe 10 can quickly drain the surface water into the river when it rains. The hydrophobic wallboard 9 is made of hydrophobic modified concrete material, so the underground seepage can also be quickly discharged into the river through the hydrophobic wallboard 9 and the underground drainage pipe 11. At the same time, the hydrophobic wallboard 9 can block the soil 4 to prevent the soil 4 from entering the underground drainage pipe 11 and causing blockage. The gabion cage 12 is a mesh cage woven from hot-dip galvanized plastic-coated steel wire, and its material has the characteristics of strong wear resistance, weather resistance and corrosion resistance. The gabion cage 12 is filled with stones 13. When the water flow impacts the wall 8, the gabion cage 12 and the stones 13 in the gabion cage 12 can It can effectively disperse the water flow, not only disperse the impact force of the water flow, but also prevent the water flow from directly impacting the wall 8, thereby preventing the wall 8 from being impacted for a long time and collapsing due to water erosion. When constructing the device, the construction personnel can first divert the river channel, and then use the silt solidification equipment to solidify the soil 4 of the river bank. After solidification, the soil 4 is compacted to form a rammed earth layer 3, and then pile holes 5 are punched in the rammed earth layer 3 and the soil 4, and prefabricated foundation piles 6 are buried. The height of the prefabricated foundation piles 6 is higher than the hole of the pile hole 5 by a certain distance. Then, cement mortar or backfill soil is filled into the gap between the prefabricated foundation piles 6 and the pile hole 5, and then gravel is used to pave a gravel layer 2. The surface of the gravel layer 2 is at a height of 1.5 meters from the top of the prefabricated foundation pile 6. The rammed earth layer 3 of the retaining wall constructed in this way has been compacted, so the soil 4 and the gravel layer 2 are not easily compressed and caused to settle. In addition, the outer part of the prefabricated foundation pile 6 is provided with annular convex patterns 7, so the friction between the prefabricated foundation pile 6 and the soil 4, the rammed earth layer 3 and the gravel layer 2 is very large, which can effectively disperse the pressure of the building on the ground into the soil layer and deep underground, further reducing the possibility of settlement of the retaining wall. The guardrail 1401 can effectively prevent If a pedestrian accidentally falls into the water, the warning sign 1402 may be marked with warning words such as "Dangerous water depth, no climbing over" to serve as a warning and prevent people from climbing over the guardrail 1401 without permission and causing drowning accidents. It can also reduce the responsibility of the management after people drown by climbing over the guardrail 1401 without permission. The wall 8 is in a stepped shape, so the gabion cage 12 placed on the wall 8 is also in a stepped shape, which not only reduces the possibility of people slipping, but also allows people to climb ashore along the gabion cage 12 even if they fall into the water, avoiding the situation where the bank slope is steep and they cannot go ashore, thereby further reducing the possibility of people drowning. This is the working principle of the retaining wall that is easy to drain.
