The invention discloses an adjustable remediation well
system for soil and underground water remediation. The adjustable remediation well
system comprises a well lid, a well body, an adjustable telescopic
pipe and a high-pressure chemical injection
pipe. The well body comprises a prefabricated screen
pipe serving as the inner wall, a hole sealing section serving as the outer wall and a filtering section. The adjustable telescopic pipe is vertically arranged in the center in the well body, is hydraulically driven and comprises at least two telescopic pipe fittings. A packer is arranged on the outer wall, close to the lower end, of each telescopic
pipe fitting; all the packers are connected with external
hydraulic control equipment through control hoses and are driven by the external
hydraulic control equipment to expand;
medicine outlets are formed in the positions, corresponding to the lower portions of the packers, of the lower portion of the high-pressure
medicine injection pipe; a
submersible pump is arranged at the bottom of the well body; the
submersible pump is connected with a ground extraction pump through an extraction pipeline. By means of the application, the injection depth and the injection section of the repairing agent can be adjusted, so that the pertinence and accuracy of repairing agent injection are improved, and the accurate repairing target is achieved.
