[0002] In order to solve the problems existing in the urban water environment, the country has creatively proposed to build a sponge city with "natural storage, natural infiltration and natural purification". The construction of sponge cities is an important conceptual change in the urban development mode, an important part of the construction of ecological civilization, and a manifestation of the mainstream values ​​of ecological civilization. Among them, "source emission reduction" is the top priority. In actual engineering practice, the "two rates" of "source emission reduction", namely, "annual runoff total control rate" and "annual runoff pollution reduction rate", are the most important indicators.

[0003] However, at present, most urban sidewalk pavements only have the function of providing pedestrian access and separating vehicles from pedestrians. The underground part of the sidewalk pavement is not effectively utilized, does not have the function of regulating and storing water and purifying water, and does not have the function of automatic monitoring and early warning, and cannot be operated and maintained in a timely manner.

DETAILED DESCRIPTION

[0022] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings.

[0023] Embodiment: A sidewalk pavement with adjustable water storage and intelligent monitoring, such as Figure 1-3 This structure is set up on both sides of the road, including sidewalk pavement 1, storage and purification facilities 2 and monitoring equipment 3.

[0024] The sidewalk pavement 1 includes a surface layer 10, a bonding layer 11, a cushion layer 12 and a soil base 13 from top to bottom, and slopes toward the regulating, storing and purifying facility 2, and is fully connected therewith. When it rains, the slope can be fully utilized to smoothly collect rainwater into the regulating, storing and purifying facility 2, preventing a large amount of water from accumulating on the sidewalk pavement.

[0025] The regulating and purifying facility 2 is set in a concrete well 25 (compacted with a well soil foundation 26 below), and a concrete and cement mortar waterproof layer is provided on the concrete surface, mainly including a landscape drainage cover plate 20, a sewage interception hanging basket 21, a regulating and slow-release device 22, a retaining wall 23 and an overflow pipe 24. Among them, the landscape drainage cover plate 20 is connected with the sidewalk pavement 1, including a rainwater grate 200 and a seamless rainwater cover plate 201, and the two are separable. Among them, the rainwater grate 200 is set on the side close to the sidewalk pavement 1, and a water collection channel 32 is set below the rainwater grate 200, so that the rainwater on the sidewalk pavement 1 can smoothly flow into the water collection channel 32, and flow and drain along the slope of the water collection channel 32 toward the position of the regulating and slow-release device 22; the seamless rainwater cover plate 201 is close to the rainwater grate 200, and its main function is to prevent pedestrians from falling into the well 25, ensure safety, and facilitate the subsequent staff to operate and maintain the facilities. The drainage trough at the bottom of the rainwater well water collection channel 32 flows into the concrete well body 25. After some suspended matter and impurities are intercepted by the sewage interception hanging basket 21, the rainwater is stored in the storage and purification facility 2 due to the storage and release device 22 at the bottom.

[0026] The regulating storage and slow-release device 22 includes a non-powered regulating storage and slow-release device 220, a sewage pipe 221 and a slow-release outlet pipe 222, which are fixed at the bottom of the well body 25. A retaining wall 23 is provided near the overflow pipe 24. Multiple groups of regulating storage and slow-release devices 22 are arranged in parallel as needed. The bottom of the non-powered regulating storage and slow-release device 220 is connected through a slow-release outlet pipe 222, and the accumulated rainwater can be slowly discharged into the overflow pipe 24 through the retaining wall and discharged into the municipal rainwater pipe network. Its advantages are fully automatic operation, no power consumption, and automatic output of the accumulated rainwater, achieving the purpose of non-powered, fully automatic, slow-release water delivery; the bottom of the non-powered regulating storage and slow-release device 220 is connected to the sewage pipe 221, which can automatically discharge the pollutants enriched at the bottom of the facility into the sewage pipe network, achieving the purpose of sewage purification. The regulating storage and slow-release device 22 is fully automatic, does not require power consumption, and has an emptying cycle of ≤24 hours, which can effectively reduce the peak value of rainwater discharge and greatly reduce the pollution of initial rain runoff.

[0027] When the rainfall is small, the rainfall runoff flows through the sidewalk pavement 1 to the opening, passes through the interception basket 21, and is stored in the storage and purification facility 2. After the rainwater is slow-released and purified by the storage and slow-release device 22, the purified rainwater flows into the overflow pipe 24 and the municipal pipe network through the slow-release outlet pipe 222, and the enriched pollutants are discharged to the sewage pipe network through the sewage pipe 221, so that it has both storage and purification functions.

[0028] When the rainfall is heavy, in addition to the above-mentioned situation where rainwater is stored in the regulation and purification facility 2, when the water level is higher than the height of the retaining wall 23, the excess rainwater can directly overflow into the overflow pipe 24 and be discharged into the municipal pipe network to prevent overflow and water accumulation due to insufficient regulation and storage.

[0029] In order to better play the storage and purification functions of the facility, monitoring facilities A30 and B31 are respectively set at point A of the drainage trough at the bottom of the water collection channel and point B of the overflow pipe 24. Monitoring facilities A30 and B31 can be set in multiple groups as needed to monitor parameters such as water volume and suspended solids (SS) concentration in real time or periodically, and comprehensively judge the operation status of the facility. When it is in an abnormal state, the staff is reminded to maintain the facility in time. The operation and maintenance warning issued by the monitoring facility varies according to the designed SS removal efficiency of the facility, and depends on the actual situation. The following is one of the cases. For example, the designed SS removal efficiency is 50%, and the monitoring facility detects that the SS concentration at point A is CA and the SS concentration at point B is CB. When the SS removal rate is automatically detected to be greater than or equal to 50%, the facility is displayed as normal; when the SS removal rate is automatically detected to be less than 50%, an early warning signal is automatically issued to the staff to remind them to clean or replace it in time. Therefore, monitoring facilities can automatically send out early warning signals, eliminating the need for staff to manually judge the condition of the facilities, and preventing certain facilities from being out of operation for a long time and not being discovered until the road is flooded, causing difficulties in operation and maintenance.

[0030] The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
