Embodiment 1

[0044] Example 1: Sponge city construction includes various technical measures such as "infiltration, stagnation, storage, purification, use, and drainage", covering low-impact development, urban stormwater pipe and channel systems, and stormwater runoff discharge systems that exceed standards, focusing on source runoff control, drainage pipes, etc. Various technical measures should be planned and designed simultaneously for the improvement of canal standards, the construction of waterlogging prevention projects, and the management of river and lake ecology. The current records on the construction of sponge cities are all based on the landscape design of the overall planning of the city, which is essentially land design and material space planning. It is based on the research process of exploring solutions to environmental, ecological and social problems existing on the land, and It requires a discussion process combined with engineering technology and humanities, social arts a...

Embodiment 2

[0055] Embodiment 2: A rainwater resource utilization system, which is planned in stages according to the current situation of the city, and divides the urban area into ecological water storage areas suitable for renovation, areas not suitable for renovation, and areas with pollution sources.

[0056] Set up settlement storage tanks at low-lying positions in part or all of the ecological water storage areas, such as Figure 1-Figure 3 shown. Areas that are not suitable for renovation should be discharged to corresponding settlement reservoirs through surface runoff and underground confluence hidden pipes by setting up ecological water storage areas, and sell water and store water through surface infiltration. The flow passage used refers to dredging from the high terrain in the adjacent area to the low terrain in the adjacent area, or dredging from the low terrain in the adjacent area to the high terrain in the adjacent area with the pump. In the end, the areas that are not s...

Embodiment 3

[0064] Embodiment 3: On the basis of Embodiment 2, an outwardly expanding conical protrusion is further provided in the sewage well, such as Figure 12 shown. The conical protruding part includes the upper conical surface of the well wall and the lower conical surface of the well wall. The inner side of the conical protruding part is set with a floating body. The floating body includes the upper conical surface of the floating body and the lower conical surface of the floating body. The suspension chain is fixed or driven, and when the floating body is located in the center of the conical protrusion, there is a matching gap between the floating body and the inner wall of the conical protrusion. After the downward movement, the lower cone surface of the floating body can be matched with the lower cone surface of the shaft wall.

Abstract

The invention discloses a rain flood resource utilization method and system. An urban region is divided into a plurality of independent subregions, wherein the subregions suitable for modification areartificially modified into ecological water storage regions; and sedimentation reservoirs are established at the lower positions of the terrains of the subregions suitable for modification, and the regions not suitable for modification communicate with the adjacent ecological water storage regions until the regions communicate with the ecological water storage regions with the sedimentation reservoirs by arranging flow passages. Each flow passage is formed by establishing an artificial water flow dredging passage on the surface or underground between adjacent regions and draining the artificial water flow dredging passage to a corresponding sedimentation reservoir in a surface runoff or underground confluence concealed pipe confluence mode. The rain flood resource utilization method and system of the invention can be transformed by combining the current situation of each city, and can arrange the regions suitable for modification at present as the modification regions of the ecological water storage regions no matter how the modification degree of the city is; and multiple functions of the ecological water storage regions are matched, effective reconstruction and rainwater resource utilization are carried out, and the urban rainwater resource utilization rate is continuously improved.

Description

technical field [0001] The invention belongs to the technical field of resource utilization of rainwater, and in particular relates to a pollution-free rainwater resource utilization method and system. Background technique [0002] my country is located in the Asian monsoon climate zone. The monsoon climate determines the relative concentration of my country's rainy season in a year. Whenever the summer monsoon goes north, the southwest and southeast warm and humid air flow meets the cold air from the westerly belt, or is affected by typhoons, which often produce heavy rainstorms. . The average annual precipitation in my country is 62 trillion m 3 , equivalent to an annual rainfall of 648mm. Abundant rainfall provides a prerequisite for the development of rainwater utilization. The purpose of urban rainwater utilization is precisely to change the high concentration of time and space distribution, and disperse it by means of interception and storage, so as to turn waste int...
