Problems solved by technology

[0003] Traditional groundwater in-situ remediation devices generally adopt a diaphragm wall structure (a continuous active infiltration wall is installed in the area where the groundwater flows to ensure that the groundwater in the polluted area can be treated and repaired). The maximum construction excavation depth shall not exceed 10m, and the phenomenon of aquifer collapse is likely to occur during the construction process, making the construction difficult, and it is difficult to achieve layered installation during the installation process

Abstract

The invention provides an underground water in-situ remediation device capable of enlarging a seepage path. The underground water in-situ remediation device comprises an outer wall pipe, a lower solid wall pipe, a water filtering pipe and an upper solid wall pipe, wherein the space between the outer wall pipe and the lower solid wall pipe is filled with a filter material, the space between the outer wall pipe and the lower half part of the water filter pipe is filled with a filter material, the space between the outer wall pipe and the upper half part of the water filter pipe is filled with a PRWB material, and the space between the outer wall pipe and the lower half part of the upper solid wall pipe is filled with a PRWB material. And a filter material is filled between the outer wall pipe and the upper half part of the upper solid wall pipe.

Description

technical field [0001] The present disclosure relates to a groundwater in-situ repairing device and method for increasing the seepage path. Background technique [0002] Groundwater is easily polluted, and once the groundwater is polluted, it is difficult to remediate it. At present, the content of nitrate nitrogen in groundwater in some areas of northern my country exceeds the standard, which poses a threat to drinking water safety and ecological environment, and seriously affects the safety of water supply and health of the people. [0003] The traditional groundwater in-situ remediation device generally adopts a diaphragm wall structure (a continuous active infiltration wall is installed in the area where the groundwater flows to ensure that the groundwater in the polluted area can be treated and repaired). The maximum construction excavation depth is not more than 10m, and during the construction process, the collapse of the aquifer is likely to occur, and the construct...
