Recharge well used for soil water storage and conservation, underground building space structure, and construction method

Abstract

The invention discloses a recharge well used for soil water storage and conservation. The recharge well comprises a well body, and a seepage pipe, wherein the well body is connected to a water permeable soil layer; and the seepage pipe is longitudinally inserted in the well body, and multiple seepage holes communication with the water permeable soil layer are formed. The invention also discloses an underground building space structure with the recharge well. The structure comprises at least one recharge well, wherein the well mouth of at least one recharge well is located on the bottom of at least one ground surface water storage facility. The invention also discloses a construction method applied to the soil water storage and conservation arrangement and comprises the steps that (a) at least one well body connected to the water permeable soil layer is excavated; and (b) the seepage pipe is longitudinally inserted into at least one well body so as to form the recharge well, wherein the multiple seepage holes are formed in the seepage pipe.

Description

technical field [0001] The invention relates to a recharge well for soil water storage and water retention, an underground building space structure and a construction method. Background technique [0002] In the prior art, the urban water supply and drainage system discharges too much rainwater or urban waste water into rivers, lakes and seas, which cannot be well preserved and reused locally. It is directly related to the replenishment of external water resources, which leads to the continuous decline of groundwater table. At present, the country is vigorously advocating the construction of sponge cities, and many technical ideas have emerged. Most of these technical ideas focus on how to collect water resources. Although it can effectively prevent the loss of water resources and achieve water conservation in a sense, but The water retention capacity is directly related to these implementation volumes. In order to achieve a larger water retention capacity, more large-capac...

[0002] In the prior art, the urban water supply and drainage system discharges too much rainwater or urban waste water into rivers, lakes and seas, which cannot be well preserved and reused locally. It is directly related to the replenishment of external water resources, which leads to the continuous decline of groundwater levels

At present, the country vigorously advocates the construction of sponge cities, and many technical ideas have emerged. Most of these technical ideas focus on how to collect water resources. Although it can effectively prevent the loss of water resources and achieve water conservation in a sense, but The water retention capacity is directly related to these implementation volumes. In order to achieve a larger water retention capacity, more large-capacity storage tanks must be built in the city, which will undoubtedly greatly increase the cost of building water storage and conservation facilities.
