Compaction and injection mechanism of soil sampling and remedying integrated drilling machine

Abstract

The invention discloses a compaction and injection mechanism of a soil sampling and remedying integrated drilling machine. The compaction and injection mechanism of the soil sampling and remedying integrated drilling machine comprises an outer soil sampling pipe; the top end of the outer soil sampling pipe is connected with a lifting and leading joint; one side of the lifting and leading joint isconnected with one port of a three-way joint; a middle port of the three-way joint is connected with a pressure meter; another port of the three-way joint is sequentially connected with a first ball valve and a second ball valve; a movable joint is connected between the first ball valve and the second ball valve; the second ball valve is connected with a slurry injection hose which communicates with a corresponding slurry injection pump; the bottom end of the outer soil sampling pipe is connected with a compaction drill bit; a jet channel is arranged inside the compaction drill bit; and a plurality of jet holes communicating with the jet channel are evenly distributed in the side circumferential face of the compaction drill bit. The chemical injection depth is higher, pressure in the pipecan be detected in real time, chemical injection is safer, disassembly is safer after the ball valves and the pressure meter are additionally installed, and disassembly is more convenient after the movable joint is additionally installed.

Description

technical field [0001] The invention belongs to the technical field of contaminated soil remediation, and in particular relates to a compaction injection mechanism of an integrated drilling rig for soil sampling and remediation. Background technique [0002] The traditional injection method is limited by the depth of the injection, and the treatment effect is often not so perfect, and under the action of the injection pressure, the internal pressure of the pipeline is also uncontrollable, and it is very inconvenient to disassemble the pressure gauge and ball valve. Invention content: [0003] The purpose of the present invention is to overcome the above problems existing in the prior art, and provide a compact injection mechanism of a soil sampling and restoration integrated drilling rig, which can realize a deeper injection depth, make the injection process safer, and facilitate the disassembly and assembly of pressure gauges and ball valves . [0004] In order to achiev...
