Abstract

The invention discloses a geotechnical engineering investigation drilling machine soil sampler which comprises a soil sampler body, the soil sampler body comprises a gasket and a connector seat connected with a drilling machine underframe, a vertically-arranged main rod is installed on the connector seat, a rotating seat is rotationally arranged at the top of the main rod, a handle is arranged on one side of the rotating seat, and the gasket is arranged on the handle. And a soil jacking rod is arranged on one side of the rotating seat. The invention further discloses a soil sampling method of the geotechnical engineering investigation drilling machine. The geotechnical engineering investigation drilling machine soil sampler and the soil sampling method belong to the technical field of geotechnical engineering investigation detection equipment, soil sampling is carried out through the soil sampler, disturbance to a soil sample is small, and the original shape of the soil sample can be fully maintained; the device is labor-saving, time-saving, efficient and high in sampling success rate; the soil sampling structure is light, energy-saving, environment-friendly and convenient to mount and dismount.

Description

technical field [0001] The invention relates to geotechnical engineering investigation and detection equipment technology, more specifically, it relates to a geotechnical engineering investigation drilling rig soil fetcher and soil fetching method. Background technique [0002] With the rapid development of science and technology, geotechnical engineering investigation is playing an increasingly important role in engineering construction. In geotechnical engineering investigation, it is often necessary to sample soil, and most of the existing soil fetchers rely on manual methods. It is slow, inefficient, and sometimes even destroys the soil sample, affecting the construction progress. Contents of the invention [0003] The technical problem to be solved by the present invention is to address some of the above-mentioned deficiencies in the prior art. One of the purposes of the present invention is to provide a geotechnical engineering reconnaissance drilling rig soil fetche...
