Title:
IN SITU REPAIR SYSTEM AND METHOD FOR IN SITU INJECTION - HIGH PRESSURE ROTARY JET INJECTION IN SOIL AND GROUNDWATER
Document Type and Number:
WIPO Patent Application WO/2017/219792
Kind Code:
A1
Abstract:
Disclosed is an in situ repair system and method for in situ injection - high pressure rotary jet injection in the soil and groundwater. The system comprises a dispensing site (1), a high pressure grouting pump (5), an air compressor (11), a rotary jet drilling machine (15), a double tube water flow joint (20), a grouting drill pipe automatic lifting mechanism (21) in the rotary jet drilling machine, a high pressure jet drill pipe (22), a high pressure jet triple inside tube (23) of the drill pipe, a high pressure jet triple outer tube (24) of the drill pipe, an agent jet nozzle (28), an air jet nozzle (30), a cemented carbide block (32) and a bit (33). Methods: arranging points according to the triangular method, wherein the parameters for arranging points ensure that the repair area is wholly covered by the agent within the range of the diffusion radius of the agent, and the hole-digging drilling machine is in place in the center of the injection point after the measurement point is GPS positioned; high pressure injection repairing using the double tube: cutting the soil from bottom to top with gas and liquid fluids at the same time, diffusion in the stratum to achieve full mixing of the repairing agent and the soil and groundwater; rapid combining laboratory testing there and then to obtain parameters of the repairing agent residues, pH value and the pollutant concentration to test the in situ repairing effect and monitor the agent residue condition.
