Description

Technical Field

[0001] This utility model relates to the field of drainage structure technology for retaining walls, specifically a drainage structure for preventing water accumulation in retaining walls for mountain roads. Background Technology

[0002] Retaining walls, as structures specifically designed to support roadbed fill or hillside soil and effectively prevent deformation and instability due to various external forces, play a crucial role in civil engineering. Especially in rainy weather conditions, retaining walls often accumulate large amounts of water, which, if not drained promptly, poses a serious threat to the stability and safety of the wall. Therefore, a reasonable and efficient drainage system is particularly important to ensure the normal function of retaining walls and extend their service life.

[0003] In existing drainage system technology, filter screens are installed inside the device to prevent the pipes from being clogged by large amounts of silt. The filter screen effectively intercepts silt particles that enter the pipes with the water flow, ensuring unobstructed drainage. However, in actual operation, it has been gradually discovered that while the filter screen plays a positive role in preventing silt blockage, a large amount of silt easily accumulates at its top. This accumulated silt accumulates over time, gradually forming a thick layer of sediment.

[0004] The long-term accumulation of silt not only occupies the effective space of drainage pipes and reduces their drainage capacity, but also seriously affects the drainage effect and speed of the system. More seriously, this accumulation may also cause filter screen blockage, rendering the drainage system ineffective and posing a potential threat to the overall stability and safety of the retaining wall. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a retaining wall structure for preventing water accumulation and drainage in mountainous areas. This solves the problem that while the aforementioned filter screen plays a positive role in preventing silt blockage, its top is prone to trapping large amounts of silt. This trapped silt accumulates over time, gradually forming a thick layer of sediment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a technical solution, please refer to Figure 1 and Figure 2 A retaining wall structure for preventing water accumulation and drainage in mountainous areas includes: a retaining wall 1 and a filter layer 2. The filter layer 2 is embedded in the top of the retaining wall 1. A water storage box 3 is embedded in the top of the retaining wall 1. A water pump 31 is connected to the bottom of the water storage box 3. A spray pipe 32 is connected to the outlet of the water pump 31. A sewage collection box 4 is embedded in the inner cavity of the retaining wall 1. A filter plate 41 is installed inside the sewage collection box 4. A sludge storage box 5 is installed on the left side of the retaining wall 1. A sludge discharge pipe 43 is connected to the outside of the sludge storage box 5. The other end of the sludge discharge pipe 43 is connected to the sewage collection box 4. A drain pipe 42 is connected to the bottom of the sewage collection box 4.

[0024] Please see Figure 3 and Figure 4 The retaining wall 1 is a common type of retaining wall in the prior art. The retaining wall 1 consists of a back wall, a base, a wall surface, a top wall, a toe wall, and a heel wall. The filter layer 2 can filter the water entering the sewage collection box 4. The sewage collection box 4, together with the filter plate 41, can filter and discharge the water inside the retaining wall 1. The drain pipe 42 can discharge the sewage. The sludge discharge pipe 43 can discharge the sludge in the sewage. The sludge storage box 5 can collect the sludge.

[0025] The top of the sludge storage box 5 is equipped with a protective cover 51, and the top of the protective cover 51 is equipped with a handle. The protective cover 51 can seal the sludge storage box 5 to prevent external soil from entering the interior of the sludge storage box 5. The sludge storage box 5 includes a square tube, and the bottom of the square tube is evenly distributed with filter holes. The filter holes at the bottom of the sludge storage box 5 can remove water from the collected sludge.

[0026] The top of the sewage collection box 4 has a slot located directly below the water spray pipe 32. The slot allows the water spray pipe 32 to discharge rainwater at an angle into the top of the filter plate 41 for cleaning. The filter layer 2 includes a square box with gravel evenly distributed inside. The bottom of the square box is connected to the top of the sewage collection box 4 via a square tube. The filter layer 2 can filter sewage through the gravel, preventing a large amount of mud from entering the sewage collection box 4. The top of the inner cavity of the water storage box 3 is fitted with a filter element 33. The filter element 33 has water inlet holes evenly distributed inside. The filter element 33 can filter and collect rainwater. At the same time, the filter element 33 is set on the top of the retaining wall 1, which facilitates cleaning and maintenance.

[0027] This solution first involves installing the retaining wall 1. During use, sewage or rainwater enters the filter layer 2 and the sewage collection box 4, is filtered by the filter plate 41, and is finally discharged through the drain pipe 42. The sludge in the sewage is retained on the top of the filter plate 41. Due to the inclined design of the filter plate 41, the sludge is discharged into the sludge storage box 5 along the filter plate 41 and the sludge discharge pipe 43 for storage, waiting for the staff to clean the inside of the sludge storage box 5. When the sludge on the top of the filter plate 41 reaches a certain amount, the water pump 31 is started to draw out the rainwater inside the filter element 33 and spray it into the inside of the filter plate 41 through the spray pipe 32 at an angle. With the inclined design of the filter plate 41, the sludge on the top is cleaned and discharged, thereby preventing the filter plate 41 from being blocked by sludge.

[0028] The added filter element 33 automatically filters and collects rainwater during rainy weather. At the same time, the added inclined filter plate 41 prevents sludge from the sewage discharged from the filter layer 2 from remaining on the outside of the filter plate 41 for a long time, thus preventing the filter plate 41 from becoming clogged. The added water pump 31 and spray pipe 32 pressurize and spray the rainwater collected by the filter element 33 onto the outside of the filter plate 41. Combined with the inclined design of the filter plate 41, the sludge on the top is cleaned and discharged for a second time, thereby preventing the filter plate 41 from being clogged by sludge. At the same time, all the sludge is collected into the sludge storage box 5, which is convenient for the staff to clean and recycle the sludge in the future.
