A kind of pressurized spring maintenance and reinjection well and its method

Abstract

The invention discloses a pressurizing and spring protection recharge well and method. The pressurizing and spring protection recharge well comprises a push rod pressure device, wherein the push rod pressure device is used for transmitting pressure to recharged water of a well pipe by a pressure conduction device; the pressure conduction device is arranged on the well pipe; a water filtering pipe is arranged under the well pipe; a water inlet channel is arranged on one side of the well pipe; a check valve is arranged at the connection part of the water inlet channel and the well pipe; the upper part of the water filtering pipe is connected with a pressure sensor; the pressure sensor is connected with a pressure control system by a steel pipe; the pressure control system is connected with a push rod pressurizing device by a pressure control connection device. According to the pressurizing and spring protection recharge well, the problems of ground subsidence caused by consolidation deformation of a ground layer adjacent to a construction region, which is caused by foundation pit dewatering, and waste of underground water resources in hydrogeological units of the construction region, which is caused by the foundation pit dewatering are solved; a series of problems that equipment and procedures are complicated, the occupying area is large, citizens are disturbed by construction and the like in a popularization process of an underground water recharge technology are solved, so that the recharge efficiency is improved and the recharge cost is reduced.

Description

technical field [0001] The invention relates to the field of construction, in particular to a treatment technology for precipitation in foundation pit engineering, which is a technology for water recharge and water conservation in foundation pits, in particular an integrated spring water conservation technology that improves recharge efficiency and reduces costs and is highly applicable. Irrigation device and method. Background technique [0002] For a relatively closed hydrogeological unit, the groundwater in the spring area has the characteristics of shallow burial and large amount of rich water. During the construction of the underground project, the excavation of the foundation pit of the soil has a large amount of precipitation, which poses a threat to the spewing of the springs, and at the same time damages the surrounding geological environment and affects the surrounding buildings. In order to balance urban construction and geological environment protection, groundw...

AI Technical Summary

Problems solved by technology

Pressurized recharge should be carried out according to the regional hydrogeological characteristics, but the general pressurized recharge equipment is cumbersome, the process is complicated, and the area is large, which is not conducive to the use in urban areas with dense buildings.

With the reform and development of the country and the improvement of people's living standards, the economy needs better development and the city needs better construction. Along with the urban construction process, foundation pit precipitation has brought more and more geological environment, construction safety, and damage to hydrogeological units. and groundwater circulation, groundwater recharge is currently an effective solution, but it is difficult to popularize and apply it due to the large area that affects the lives of surrounding residents and cumbersome construction.
