Document Type and Number:
WIPO Patent Application WO/2023/236912
Kind Code:
A1
Abstract:
A contaminated site in-situ remediation system and remediation method. The contaminated site in-situ remediation system comprises a direct-push drilling rig (1), a drilling tool supply apparatus (2) and a chemical agent supply apparatus (3). The direct-push drilling rig (1) is configured to act on a drilling tool (21) in the drilling tool supply apparatus (2), so as to cause the drilling tool (21) to reach a preset remediation position (101). The chemical agent supply apparatus (3) comprises at least two chemical agent tanks (31), an injection pump (32), an air compressor (33) and a fluid switching device (34), wherein the chemical agent tanks (31) are in communication with the injection pump (32) via pipes; the injection pump (32) and the air compressor (33) are in communication with the fluid switching device (34) via pipes; and the fluid switching device (34) is in communication with the drilling tool (21) in the drilling tool supply apparatus (2) via a pipe, so that chemical agent channels in the chemical agent tanks (31) and the drilling tool (21) form different paths, and chemical agents in the chemical agent tanks (31) reach the preset remediation position (101) through the drilling tool (21).
