Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of municipal drainage, and in particular to a municipal road drainage system. Background Technology
[0002] With urbanization, road network density has increased, and the area of paved roads has expanded. The impermeability of the ground surface has also increased, meaning rainwater cannot naturally infiltrate through the road surface. Instead, it is collected by roadside rainwater collection inlets and transported through municipal stormwater pipe networks, significantly increasing the pressure on municipal drainage systems. When rainfall intensity exceeds the drainage system's capacity, urban flooding is highly likely. Roads constitute a large proportion of the urban surface area, and the volume of surface runoff generated during rainfall is also substantial. Due to the porosity and permeability limitations of paved road structures, approximately 80% of road surface runoff is directly discharged through roadside rainwater collection inlets, failing to replenish groundwater or be utilized.

[0012] Preferably, a filter screen is provided at the connection between the connecting pipe and the drainage ditch.
[0013] Compared with the prior art, this utility model provides a municipal road drainage system with the following beneficial effects: When it rains, rainwater on the municipal road flows into the drainage ditches on both sides, and then flows into the storage tank through the connecting pipe, preventing rainwater from flowing directly into the municipal drainage system and effectively mitigating the impact of heavy rain on the municipal drainage system.

[0023] Example 1
[0024] Please refer to Figure 1-3 A municipal road drainage system specifically includes: drainage ditches 1 set on both sides of the municipal road, a water storage tank 2 arranged corresponding to the drainage ditches 1, multiple connecting pipes 3, and multiple overflow seepage pipes 4. The drainage ditches 1 and the water storage tank 2 are arranged parallel to the municipal road. One end of the multiple connecting pipes 3 extends into the drainage ditches 1, and the other end of the multiple connecting pipes 3 extends into the water storage tank 2. One end of the overflow seepage pipe 4 extends into the upper part of the water storage tank 2, and the other end of the overflow seepage pipe 4 extends underground. Furthermore, the multiple overflow seepage pipes 4 are symmetrically arranged on both sides of the water storage tank 2 and are evenly distributed. The water storage tank 2 is made of concrete to ensure the structural strength of the water storage tank 2. The drainage ditches 1 are used to collect rainwater on both sides of the municipal road.
[0025] For details, please refer to Figure 1 The upper part of the water storage tank 2 is provided with an open pool 12; furthermore, the open pool 12 is used for planting plants for road green belts.
[0026] For details, please refer to Figure 2 A filter screen 19 is provided at the connection between the connecting pipe 3 and the drainage ditch 1.
[0027] For details, please refer to Figure 3 or Figure 4 The top wall of the water storage tank 2 is made of a porous permeation plate 17; furthermore, the top wall of the water storage tank 2 is made of a ceramic permeation plate or other permeation plate that allows water to pass through; a reinforcing beam can be set at the bottom of the porous permeation plate 17 to improve the load-bearing strength of the porous permeation plate 17.
[0028] The municipal road drainage system provided in this embodiment can bury the water storage tank 2 under the green belt on both sides of the road, plant green plants in the open pool 12, and the loose soil in the open pool 12 can also store rainwater in the early stage. When there is too much rainwater in the open pool 12, some rainwater seeps down into the water storage tank 2 through the porous infiltration plate 17. In sunny weather, after the rainwater in the water storage tank 2 evaporates, it enters the soil in the open pool 12 through the porous infiltration plate 17 to replenish the water for the green plants. The filter screen 19 can prevent external debris from entering the water storage tank 2 to ensure the cleanliness of the rainwater collected in the water storage tank 2.
[0029] For details, please refer to Figure 3 It also includes a booster pump 5 and an outlet pipe 6. The lower part of the water storage tank 2 is provided with a partition plate 7, which divides the water storage tank 2 into an upper chamber 8 and a lower chamber 9. The input end of the booster pump 5 extends into the upper chamber 8, and the output end of the booster pump 5 is connected to the input end of the outlet pipe 6. The output end of the outlet pipe 6 extends into the lower chamber 9. The bottom of the water storage tank 2 is provided with multiple pressurized seepage pipes 10 that are connected to the lower chamber 9. It should be noted that the pressurized seepage pipes 10 should avoid underground subway tunnels, etc. The booster pump 5 is fixedly installed on the upper part of the partition plate 7.
[0030] For details, please refer to Figure 3-4 It also includes a level gauge 11, which is coupled to the pressure pump 5; furthermore, the level gauge 11 is used to monitor the liquid level at the upper cavity 8 inside the water storage tank 2. The level gauge 11 is preferably an ultrasonic level gauge, and the level gauge 11 is connected to the pressure pump 5 via an external PLC system.
[0031] For details, please refer to Figure 4 The outlet pipe 6 extends upward to the upper part of the water storage tank 2 and then downward to the lower cavity 9. A switch valve 15 is installed on the outlet pipe 6, and an outlet valve 16 communicating with the inside of the outlet pipe 6 is provided on the outlet pipe 6. Furthermore, the switch valve 15 is preferably an electrically controlled valve, which is connected to the level gauge 11 via an external PLC system signal. The electrically controlled valve can also be a manual butterfly valve. The outlet valve 16 is preferably a water pump connector.
[0032] For details, please refer to Figure 1 and Figure 3 A manhole 13 is provided on the top of the water storage tank 2, and a manhole cover 14 is hinged to the manhole 13.
[0033] For details, please refer to Figure 5 Both the overflow seepage pipe 4 and the pressurized seepage pipe 10 have multiple seepage holes 18 at the bottom outer wall that communicate with the inside of the overflow seepage pipe 4.
[0034] In the municipal road drainage system provided in this embodiment, after the level gauge 11 detects that the liquid level in the upper chamber 8 of the water storage tank 2 is too high, it transmits the signal to the booster pump 5 via the external PLC system. After the booster pump 5 is turned on, the water in the upper chamber 8 is pressurized and injected into the lower chamber 9. The water pressure in the lower chamber 9 increases, and some rainwater seeps into the ground through the pressurized infiltration pipe 10, replenishing the urban groundwater while further reducing the pressure on the urban drainage system; while the infiltration hole 18 can improve the overflow infiltration pipe 4 and The pressurized infiltration pipe 10 increases the infiltration area of rainwater, thereby improving the efficiency of rainwater infiltration into the ground. When it is necessary to extract rainwater from the upper cavity 8 of the water storage tank 2, the switch valve 15 is closed and the outlet valve 16 is opened. After the pressurization pump 5 is started, the rainwater in the upper cavity 8 is discharged through the outlet valve 16. The rainwater discharged through the outlet valve 16 can be used for washing urban roads or watering green plants. Operators can enter the upper cavity 8 through the manhole 13 to facilitate maintenance and repair of the equipment in the upper cavity 8.
[0035] The usage process of the municipal road drainage system provided by this utility model is as follows: When it rains, the rainwater on the municipal road flows into the drainage ditches 1 on both sides. The rainwater flows into the storage tank 2 through the connecting pipe 3, avoiding the rainwater from flowing directly into the municipal drainage system and effectively mitigating the impact of heavy rain on the municipal drainage system. When the liquid level in the storage tank 2 is higher than the overflow infiltration pipe 4, some rainwater flows into the ground through the overflow infiltration pipe 4. When the rainwater level in the upper cavity 8 rises further, the pressure pump 5 is started, and some rainwater seeps further into the ground through the pressurized infiltration pipe 10. In this way, the water storage and buffering of urban rainwater and the effective replenishment of urban groundwater are achieved.
