Abstract

The embodiment of the invention provides a high-pressure injection device for contaminated soil and underground water as well as a vehicle. The high-pressure injection device comprises an air supply device, a first liquid medicine supply device, a second liquid medicine supply device, a first liquid medicine injection device, a second liquid medicine injection device, an injection part and an aircompression device, wherein through the air supply device and the first liquid medicine supply device, first liquid medicine is injected into the first liquid medicine injection device; through the air supply device and the second liquid medicine supply device, second liquid medicine is injected into the second liquid medicine injection device; through the first liquid medicine injection device and/or the second liquid medicine injection device; the first liquid medicine and/or the second liquid medicine are/is conveyed to the injection part; through the air compression device, air is conveyedto the injection part; and through the injection part, the air, the first liquid medicine and/or the second liquid medicine are/is injected into soil. Consequently, the problem that the ground rigidity and the ground endurance are reduced due to a conventional tubular rock breaking device, and then a surface bump is formed and adjacent structures are destabilized can be solved.

Description

technical field [0001] The invention relates to the field of soil pollution treatment and high-pressure injection devices, in particular to a high-pressure injection device and a vehicle for polluting soil and groundwater. Background technique [0002] Fracturing is a soil remediation technology that sprays water or air at high pressure into the site to expand the intervals in the soil or form new fragmentation intervals, improve the permeability of the soil, and improve the extraction and treatment efficiency of pollutants. It is divided into air crushing technology that injects high-pressure air according to the injection medium and hydraulic crushing technology that injects water or mud. in, [0003] (1) Air crushing, pouring air into the fracturing wells, blowing compressed air intermittently at specified depths (for a short time, about 20 seconds) to crush the site. [0004] (2) Hydraulic crushing, the injection fluid can be a slurry mixed with water, sand and glue. ...
