Embodiment 1

[0044] Such as figure 1 with figure 2 As shown, a recharge system for rainwater storage and monitoring (hereinafter referred to as recharge system) of the present invention is built in a rainwater garden. The aforementioned rainwater garden refers to artificially excavated shallow concave green spaces, which are mainly used for gathering and combining Absorb rainwater from the ground, purify rainwater through the comprehensive action of plants and sand, and gradually infiltrate the soil to conserve groundwater. It can be used as an ecologically sustainable rainwater control and rainwater utilization facility. The recharge system of the present invention combines the natural hydrogeological conditions of the rainwater garden to transform the vadose zone and natural aquifer in the soil, and quickly stores the rainwater on the spot; further, it can also perform natural water quality filtering and filtering for rainfall. Biodegradation prevents rainwater from infiltrating into the ...

Embodiment 2

[0057] The content of this embodiment is basically the same as that of embodiment 1, except that: a recharge system for rainwater storage and monitoring of the present invention includes a buried recharge well 100 and a monitoring well 200. The buried recharge well 100 is arranged around the monitoring well 200, and the center distance D between the buried recharge well 100 and the monitoring well 200 is 2m; the number of buried recharge wells 100 is greater than the number of monitoring wells 200, and the buried recharge wells in this embodiment The number of irrigation wells 100 is 5, and the number of monitoring wells 200 is one. The buried recharge well 100 and the monitoring well 200 are located in the same aquifer area.

[0058] The diameter d1 of the reinjection well pipe 110 in this embodiment is 1.1m. The reinjection well pipe 110 is successively provided with an upper seepage section 111, a water diversion section 112 and a lower seepage section 113 from top to bottom, ...

Embodiment 3

[0060] Such as Figure 5 As shown, in the construction method of a recharge system of the present invention, the specific steps of the construction method are as follows:

Abstract

The invention discloses a recharge system for rainwater storing and monitoring and a construction method of the system, and belongs to the technical field of urban water conservancy facilities. The recharge system involves buried type reperfusion wells and monitoring wells, wherein the buried type reperfusion wells are arranged around the monitoring wells in a surrounding mode, the number of the buried type reperfusion wells is greater than the number of the monitoring wells, the circle center distance of the buried type reperfusion wells and the monitoring well is D, and D is larger than or equal to 1 meter and less than or equal to R / 2, R is the influence radius of the monitoring well. According to the system, the recharge system is built in the rainwater garden, natural water quality filtration and biodegradation are performed on rainfall by using the recharge system, secondary pollution to underground water caused by rainwater is avoided, and meanwhile, the permeation rate of the rainwater stored in the water-containing layer in situ is accelerated.

Description

Technical field [0001] The invention relates to the technical field of urban water conservancy facilities, and more specifically, to a recharge system for rainwater storage and monitoring and a construction method of the system. Background technique [0002] Problems such as river accumulation and traffic paralysis caused by floods have severely restricted urban construction. At the same time, more than 400 cities in my country still have insufficient water supply. One of the important reasons for the concurrent occurrence of water shortages and flood disasters is that water resources are not fully utilized, but are discharged through the drainage system. However, the design standards of urban drainage facilities in my country are low, and there is no complete urban drainage standard system. Severe water accumulation and waterlogging problems occurred during heavy rain, which aggravated the problems of urban water pollution and deterioration of the ecological environment. [0003] ...
