Method for controlling sedimentation through recharging engineering groundwater

Abstract

The invention discloses a method for controlling sedimentation through recharging engineering groundwater, comprising the following steps of: establishing a plurality of recharging working wells; ejecting a preset pipe to establish a recharging pipe; pumping groundwater in a dewatering well, meanwhile, carrying out purification treatment on the pumped groundwater, and recharging the groundwater to a water-bearing stratum. Due to the adoption of the method for controlling sedimentation through recharging engineering groundwater in the invention, high-flow groundwater recharge is realized, and groundwater pumping and recharging are kept balanced; and the method has the advantages of low cost, high efficiency, good sedimentation control effect and environment friendliness.

Description

technical field [0001] The invention relates to a method for controlling settlement, in particular to a method for engineering groundwater recharging to control settlement. Background technique [0002] At present, a large amount of groundwater is exploited in my country's industrial production and engineering construction, and a series of serious problems such as continuous decline of groundwater level and land subsidence have emerged; among them, underground engineering dewatering construction has become an important way of groundwater exploitation. In order to improve the problems caused by the exploitation of groundwater, in addition to controlling the exploitation of groundwater from the policy, measures such as recharge can be taken to control it. Under normal circumstances, tube wells are used for groundwater recharge, but the diameter of existing tube wells is small, and the recharge volume of a single well is small, so the number of recharge wells required to be dri...

AI Technical Summary

Problems solved by technology

Under normal circumstances, tube wells are used for groundwater recharge, but the diameter of existing tube wells is small, and the recharge volume of a single well is small, so the number of recharge wells required to be drilled is large, resulting in high cost and difficult to achieve the design. The amount of recharge is relatively low, and the effect of controlling the settlement is relatively poor.
