Drilling rig for landfill

Abstract

The invention relates to a drilling machine for a garbage landfill. The drilling machine for the garbage landfill comprises a working platform, a supporting frame, a rotating driving part, a drillingrod, a hydraulic driving mechanism, a sampling cylinder, a squeezing and pushing rod and a drilling bit; a plurality of annular clamping grooves are formed in the outer wall of the drilling rod at intervals; the hydraulic driving mechanism comprises at least one hydraulic cylinder and a clamping part; the clamping part is arranged out of the drilling rod in a sleeving mode and can be fastened in one of the annular clamping grooves; the clamping part is driven to go up or go down by the hydraulic cylinder; the sampling cylinder is in detachaly connected to the bottom end of the drilling rod; apiston head is arranged at the end of the squeezing and pushing rod and is slidably arranged in the sampling cylinder; a rod body of the squeezing and pushing rod is arranged in a through hole of thetop end of the sampling cylinder in a penetrating mode; the drilling bit is fixed at the bottom end of the sampling cylinder and is of an annular structure, and a plurality of cutting teeth are arranged on the bottom end of the drilling bit at intervals; and the cutting teeth are remaining parts after the rectangular arc face teeth. The drilling machine for the garbage landfill can reduce difficulty of hole drilling and obtain garbage samples of core morphology.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a drilling rig for landfill. Background technique [0002] Borehole sampling is an important method for assessing landfill contamination and remediation indicators. However, due to the complex composition of domestic waste (including plastic bags, worn-out clothes, branches, etc.) and large discrete types, there are many differences between landfill sampling and traditional geotechnical engineering sampling techniques. The sampling methods of impact and hammering are not effective when encountering loose and elastic garbage, and the auger will destroy the garbage sample and form a core. [0003] The drilling sampling equipment in the prior art is difficult to drill holes in fresh garbage mixed with plastic bags or fabrics, and the samples are easily broken and difficult to form cores after being taken out. Contents of the invention [0004] The invention prov...
