Description

Technical Field

[0001] The utility model belongs to the technical field of drainage systems, in particular to a sponge urban drainage system for municipal roads in collapsible loess sites. Background Art

[0002] In recent years, natural disasters caused by extreme weather have occurred frequently, exposing many shortcomings and weaknesses in urban emergency management. Sponge city construction, as an emerging model for urban waterlogging management, can effectively enhance the city's "resilience" in adapting to climate change and resisting rainstorm disasters. For municipal roads in collapsible loess sites, corresponding drainage systems need to be designed to prevent roads from being damaged by long-term waterlogging.

[0003] Although the existing system can effectively drain water from roads, the water pipes connected to the roads are easily blocked by plant growth, which makes maintenance inconvenient.

[0004] For example, a sponge city road graded drainage system in a collapsible loess layer with application number CN202111227247.3 includes a curb storage box, which is located at the junction of the road surface and the green belt. The side opening of the curb storage box close to the green belt is connected to the primary drainage pipe, and the water barrier wall is located at the lower part of the curb storage box. The vegetation planting layer, water absorption layer, ash soil cushion layer and anti-seepage membrane are arranged in the middle of the two water barrier walls from top to bottom. The seepage box is located in the ash soil cushion layer, and the side of the seepage box close to the road direction is provided with two openings from bottom to top, which are respectively connected to the secondary drainage pipe and the tertiary drainage pipe. The water diversion pipe connected to the road of this system is easily blocked by plant growth, which makes maintenance inconvenient. Utility Model Content

[0005] The utility model aims to provide a sponge urban drainage system for municipal roads in collapsible loess sites to solve the problems raised in the background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sponge urban drainage system for municipal roads in collapsible loess sites, comprising:

[0007] Two side-by-side watertight walls and a drainage system installed on the inner side of the watertight walls for municipal roads in collapsible loess sites;

[0008] A plurality of water pipes are plugged in side by side on the upper part of the water-blocking wall on one side, and two mounting plates are installed side by side on the inner wall of the water-blocking wall on this side, a connecting frame is arranged between the two mounting plates, and a leak-proof net is nested and installed on the inner side of the connecting frame, rotating shafts are installed in the middle of the outer walls on both sides of the symmetrical connection frame, and the rotating shafts are movably plugged in the corresponding sides of the mounting plates, a servo motor is installed on the outer side of the mounting plate on one side, and the servo motor is coaxially connected to one of the rotating shafts, a plurality of discharge pipes are plugged in side by side on the lower part of the water-blocking wall on the other side, and a baffle corresponding to the discharge pipe is hinged on the outer wall of the water-blocking wall on this side.

[0009] In a further embodiment, the drainage system includes a planting layer and cement slabs arranged on both sides of the planting layer, and the cement slabs are cast on corresponding sides of the water-retaining wall.

[0010] In a further embodiment, a water-absorbing layer is laid under the planting layer, a permeable geotextile is laid under the water-absorbing layer, and a seepage box is supported at the bottom of the permeable geotextile, and a plurality of drainage pipes are plugged in side by side at the top of the seepage box.

[0011] In a further embodiment, the drainage pipe passes through the permeable geotextile and the water-absorbing layer and contacts the bottom of the planting layer, and a filter net is nested and installed on the top of the drainage pipe.

[0012] In a further embodiment, the discharge pipe is connected to the bottom of a side wall of the seepage box, and a plurality of thin tubes are inserted side by side at the bottom of the seepage box.

[0013] In a further embodiment, a lime soil cushion layer is laid on the bottom of the seepage box, and the capillary tubes are inserted into the corresponding sides of the lime soil cushion layer.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0015] In the sponge city drainage system of the municipal road in the collapsible loess site, the water on the road reaches the top of the drainage system through multiple water diversion pipes. In order to consolidate the collapsible loess, a planting layer is usually laid above the drainage system to plant plants. The wanton growth of plant branches and trunks may block the corresponding side of the water diversion pipe, which is quite inconvenient when maintaining the water diversion pipe. This solution can effectively avoid the blockage of plant branches and trunks by shielding the water diversion pipe through the anti-leakage net. When maintenance is needed, it only needs to control the anti-leakage net to flip 180° through the servo motor to expose the corresponding side of the water diversion pipe, which makes the maintenance of the water diversion pipe connected to the road more convenient;

[0016] The accumulated water on the road seeps through the planting layer to the water-absorbing layer and the inside of the drainage pipe. The water-absorbing layer can absorb part of the rainwater, and the rest of the rainwater flows into the seepage box through the drainage pipe. Most of the rainwater in the seepage box is discharged through the discharge pipe, and a small part is discharged into the ground through the fine tube. The above structure is used to ensure the drainage performance, and it is laid from bottom to top in the water-absorbing layer, and then the planting layer is laid after the cement slab is poured. It is convenient to lay out while ensuring the drainage performance.

[0017] The sponge urban drainage system for municipal roads in collapsible loess sites is more convenient to maintain the water pipes connected to the roads and is easy to lay out while ensuring drainage performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0028] In order to make the maintenance of the water diversion pipe 2 connected to the road more convenient, Figures 1 to 4 A sponge city drainage system for a municipal road in a collapsible loess site is shown, comprising: two side-by-side waterproof walls 1 and a drainage system for the municipal road in a collapsible loess site installed on the inner side of the waterproof wall 1. A plurality of water pipes 2 are plugged in side by side on the upper part of the waterproof wall 1 on one side, one end of the water pipe 2 faces the edge of the road, and the accumulated water on the road can be led into the top of the drainage system. Two mounting plates 3 are installed side by side on the inner wall of the waterproof wall 1 on this side through multiple sets of screws, a connecting frame 4 is arranged between the two mounting plates 3, and a leak-proof net 5 is nested and installed on the inner side of the connecting frame 4, which can block the front of the mounting plate 3 to prevent plant branches from growing into the water pipe 2.

[0029] A rotating shaft (not shown in the figure) is installed in the middle of the outer walls on both sides of the symmetrical connection frame 4, and the rotating shaft is movably plugged into the corresponding side of the mounting plate 3. A servo motor 6 is installed on the outer side of the mounting plate 3 on one side through a motor seat, and the servo motor 6 is coaxially connected to one of the rotating shafts. The side wall of the servo motor 6 is provided with a waterproof shell, which can be connected to an external power supply when needed. The connection frame 4 can be driven to rotate by the servo motor 6 to adjust the connection frame 5 and the anti-leakage net 5 inside it to rotate. A plurality of discharge pipes 7 are plugged in side by side at the lower part of the water-blocking wall 1 on the other side, and the outer wall of the water-blocking wall 1 on this side is hinged with a baffle 8 corresponding to the discharge pipe 7, and the bottom of the baffle 8 is against the ground, which can block and protect the discharge pipe 8.

[0030] In order to facilitate the layout while ensuring the drainage performance, the drainage system includes a planting layer 10 and cement boards 9 arranged on both sides of the planting layer 10, and the cement boards 9 are cast on the corresponding sides of the water-blocking wall 1. The setting of the cement boards 9 can prevent plants from taking root here to a certain extent, and further prevent plant growth from clogging the water pipe 2. A water-absorbing layer 11 is laid under the planting layer 10 to absorb part of the rainwater. A permeable geotextile 12 is laid under the water-absorbing layer 11 to prevent the gravel in the water-absorbing layer 11 from wearing the seepage box 13.

[0031] The bottom of the permeable geotextile 12 supports a seepage box 13, and the top of the seepage box 13 is plugged with multiple drainage pipes 14 in parallel. The drainage pipes 14 penetrate the permeable geotextile 12 and the water-absorbing layer 11 and abut against the bottom of the planting layer 10. Rainwater is filtered by the filter net 15 and then falls into the inner side of the seepage box 13 through the drainage pipe 14. The top of the drainage pipe 14 is nested with a filter net 15. The discharge pipe 7 is connected to the bottom of one side wall of the seepage box 13. Most of the rainwater will be discharged through the multiple drainage pipes 7. The bottom of the seepage box 13 is plugged with multiple fine tubes 17 in parallel, and a small part of the rainwater located on the inner side of the seepage box 13 is discharged into the ground through the multiple fine tubes 17. The bottom of the seepage box 13 is paved with a ash soil cushion layer 16, and the fine tubes 17 are plugged on the corresponding side of the ash soil cushion layer 16. It has a strong bearing capacity and lays a good foundation for the drainage system.

[0033] How it works

[0034] The sponge urban drainage system for municipal roads in collapsible loess sites, when water accumulates on the road due to rain, the water diversion pipe 2 can lead the accumulated water on the road to the top of the drainage system, and the rainwater seeps through the planting layer 10 to the water absorption layer 11 and the inner side of the drainage pipe 14, the water absorption layer 11 can absorb part of the rainwater, and the rest of the rainwater flows into the seepage box 13 through the drainage pipe 14, most of the rainwater in the seepage box 13 is discharged through the discharge pipe 7, and a small part is discharged into the ground through the capillary 17, and the drainage performance is ensured by the above-mentioned segmented drainage structure;

[0035] The anti-leakage net 5 is usually shielded on the corresponding side of the water pipe 2, which can effectively prevent the water pipe 2 from being blocked when the branches of plants grow. When maintenance is needed, the anti-leakage net 5 on the inner side of the mounting plate 3 only needs to be turned 180° (such as Figure 1 ) can expose the corresponding side of the water pipe 2, and then the water pipe 2 can be maintained without being blocked by branches.
