Embodiment 1

[0044] Please also refer to Figure 1 to Figure 5 Now, a specific implementation of a shift-alternative recharge system provided by the present invention will be described. This alternate recharge system includes ditches 2, recharge wells 1 and extraction devices 3, wherein the ditch 2 is used as a flow path for the supply water source; there are several recharge wells 1, and each recharge well 1 is set independently of each other , the reinjection well 1 is connected with the ditch 2, and the filter layer 11 is arranged in the reinjection well 1; the extraction device 3 is connected with the reinjection well 1.

[0045] The channel 4 provides the supplementary water source for the groundwater artificial recharge system, and the ditch 2 guides the surface water body into the recharge well 1. The diameter of the recharge well 1 is 500-600mm is more suitable, and the recharge well 1 is used to replenish the recharge water source The aquifer increases the storage of groundwater ...

Embodiment 2

[0049] As a specific implementation of the embodiments of the present invention, please refer to Figure 1 to Figure 5 , the structure of the recharge system provided by this embodiment is basically the same as that of embodiment 1, the difference is that the recharge well 1 also includes a recharge well main body 12, a well cover 13, a start switch 14, a water stop 15 and a water filter pipe 16, wherein the main body of the reinjection well 12 is provided with a water inlet 121 and a water outlet 122, and the main body of the reinjection well 12 is connected with the filter layer 11; connection, the manhole cover 13 is provided with a survey port 131, and the extraction device 3 extends into the reinjection well 1 through the survey port 131; the start switch 14 is arranged at the water inlet 121; The main body 12 is connected, and a channel for water flow is formed in the middle of the water-stop layer 15; the water filter pipe 16 is arranged at the bottom of the recharge we...

Abstract

The invention discloses an alternate replacement type recharge system. The alternate replacement type recharge system comprises a ditch, a plurality of recharge wells and an extraction device, whereinthe ditch is used as a flow path of a replenishment water source; the multiple recharge wells are independently arranged, the recharge wells are communicated with the ditch, and filter layers are arranged in the recharge wells; and the extraction device is communicated with the recharge wells. The alternate replacement type recharge system is suitable for the conditions that an aquitard is distributed on the ground surface and a continuous sand layer is distributed on the lower portion, water is introduced into the sand layer through the recharge system, the infiltration efficiency is guaranteed, meanwhile, the problems that a traditional out-of-wall filtering device is difficult to clean after being blocked and the recharge efficiency is influenced are solved through alternate replacement type recharge and regular backwashing, and efficient and long-term operation of the recharge wells is guaranteed while the available quantity of underground water resources is increased. Infiltration efficiency is effectively guaranteed, blockage is relieved, practicability is high, uninterrupted recharge can be achieved, recharge efficiency is guaranteed, the construction cost is low, and the system is suitable for wide popularization.

Description

technical field [0001] The invention relates to the fields of hydrogeology, groundwater science and engineering technology, and in particular to a recharge system of alternate resting type. Background technique [0002] Under the background of global water resource shortage and serious overexploitation of groundwater, artificial groundwater recharge technology has attracted the attention of countries all over the world. Reasonable use of artificial recharge technology can effectively replenish depleted groundwater resources and solve a series of environmental geological problems such as land subsidence, seawater intrusion, and land desertification. However, the blockage problem in the process of artificial replenishment is always the key restricting factor for the popularization and utilization of this technology. In the engineering practice of artificial groundwater recharge, how to ensure and improve the infiltration efficiency, quickly and safely store the recharge water...
