Description
Technical Field
The invention belongs to the technical field of sponge city construction and rainwater resource utilization, and particularly relates to a sponge city rainwater deep well linkage permeation supply system.
Background
The sponge city is a new generation of city rainfall flood management concept, and refers to a city which can be like a sponge and has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters caused by rainwater and the like, and the city can also be called as a water elasticity city. The international general term is 'low-impact development of rainwater system construction', water absorption, water storage, water seepage and water purification are carried out when raining, and the stored water is released and utilized when needed, so that rainwater can freely migrate in cities. Sponge city construction should follow ecological priority principle etc. combines together natural way and artificial measures, under the prerequisite of guaranteeing urban drainage waterlogging prevention safety, furthest realizes that rainwater stores up, permeates and purifies in the urban area, promotes the utilization of rainwater resource and ecological environment protection. Rainwater is used as an important source of urban water resources, and is collected, purified and reused, so that the urban flood control and drainage pressure can be reduced, and the construction cost of pipe network engineering is reduced; but also can adjust and supplement regional water resources. The sponge city is used as a path for restoring city water ecology, can realize the recycling and reutilization of water, saves water, solves the increasingly serious ecological crisis of water environment in more and more cities, and reduces the damage to the original water ecological environment of the city to the maximum extent.
A large amount of rainfall can only be discharged outside through a rainwater pipe network due to the fact that a large amount of hardened pavements exist in a traditional city, rainwater resources cannot be well utilized, and underground water in the city cannot be effectively supplemented. After the concept of sponge city is proposed, some relevant technical publications about the construction of sponge city systems are provided, for example, the Chinese patent publication with application number of CN201710158680.3 discloses a comprehensive system for collecting, purifying and utilizing rainwater in sponge city, which comprises a roof rainwater collecting region, a road rainwater collecting region, a greenbelt rainwater collecting region, a water collecting and sand precipitating tank, a purifying device and a reservoir, wherein the roof rainwater collecting region is sequentially provided with an evaporation-proof layer, a soil layer, a water supply layer and a purifying layer from top to bottom; a transverse water collecting pipe and a longitudinal water collecting pipe are arranged in the crushed stone layer at the bottom of the road rainwater collecting region; the green land rainwater collecting area is sequentially provided with an evaporation prevention layer, a soil layer, a coarse sand layer and a purification layer from top to bottom; the middle part of the reservoir is provided with a filtering grid, the upper part of the reservoir is provided with a water inlet hole and an overflow hole, and the bottom of the reservoir is provided with a water pump. The invention not only can green and beautify urban environment, but also can relieve urban rainfall flood pressure, absorb pollutants in rainwater, save water resources, improve rainwater utilization efficiency, and has important reference significance for non-point source pollution control of sponge cities and relieving urban water shortage. However, the system has a complex structure, is difficult to operate practically and has high cost.
For another example, the chinese patent with application number CN201710158689.4 discloses a three-stage rainwater collection, purification and utilization system for mountain sponge cities, which comprises a rainwater collection system, a rainwater purification system and a rainwater utilization system, wherein the rainwater collection system comprises a plurality of greening grooves, a plurality of sand settling ponds and a plurality of water collection tanks sequentially arranged along the top of a mountain to the waist of the mountain; the rainwater purification system is formed by mutually arranging a plurality of primary purification tanks and a plurality of secondary purification tanks in a stepped manner downwards along a mountain, wherein the primary purification tanks are sequentially provided with an anti-scouring layer, a soil layer, a coarse sand layer and a purification layer from top to bottom; the secondary purification tank is sequentially provided with a soil layer and a filter layer from top to bottom; the rainwater utilization system comprises an upper landscape pool and a lower reservoir, and a concrete partition plate is arranged between the landscape pool and the reservoir. The invention can not only green and beautify mountain environment, has good landscape effect, but also can absorb pollutants in rainwater to purify water, and is particularly suitable for mountain sponge city construction with water resource shortage. But the system is more suitable for mountain cities, and has a smaller application range.
In summary, the current urban rainwater collection and utilization system still needs to be improved, so that the concepts of natural storage, natural infiltration and natural purification of a sponge city are necessarily combined, and the rainwater deep well linkage infiltration replenishment system with comprehensive functions, which can not only green and beautify the urban environment, but also relieve the urban waterlogging, reduce the ground runoff and replenish the underground water through infiltration, so as to realize the utilization of energy-saving rainwater in the sponge city and the control of urban non-point source pollution, is developed.
