Novel geotechnical engineering investigation sampler

Abstract

The invention discloses a novel geotechnical engineering investigation sampler and relates to the field of a sampler. The novel geotechnical engineering investigation sampler comprises a top plate, a shaft sleeve is fixedly connected to the middle of the top end of the top plate in a penetrating mode, a soil sampling barrel is movably inserted into the top end of the shaft sleeve in a penetrating mode, the outer wall of the top of the soil sampling barrel is in threaded connection with the inner wall of the shaft sleeve through an formed threaded groove, and a push rod is movably inserted into the top end of the soil sampling barrel in a penetrating mode; the bottom end of the push rod is fixedly connected with a push plate and provided with a reset mechanism; and the top end of the push rod is provided with a rotating mechanism. The push rod and the push plate which are arranged in the soil sampling cylinder are matched with the reset mechanism for use, so that a rock-soil sample obtained in the soil sampling cylinder can be quickly discharged, meanwhile, the soil sampling cylinder does not need to be manually knocked or disassembled, the unloading convenience of the sampler is improved, the labor intensity of an operator is reduced, and the subsequent soil sampling efficiency is improved.

Description

technical field [0001] The invention relates to the field of samplers, in particular to a novel geotechnical engineering investigation sampler. Background technique [0002] Engineering survey refers to the activities of surveying and mapping, surveying and testing terrain, geology and other conditions to meet the needs of engineering construction planning and construction, and providing corresponding results and materials. With the acceleration of urbanization, the demand for engineering surveys is gradually increasing. The equipment used for engineering investigation has also been improved, and the sampler used for rock and soil sampling is widely used. [0003] Most of the samplers used today use a sampling cylinder or a drill pipe with a threaded groove to rotate and drill into the rock and soil, thereby pressing the rock and soil into the sampling cylinder or the threaded groove of the drill pipe, so as to realize the detection of rock and soil at different depths.

Problems solved by technology

[0003] Most of the samplers used today use a sampling cylinder or a drill pipe with a threaded groove to rotate and drill into the rock and soil, thereby pressing the rock and soil into the sampling cylinder or the threaded groove of the drill pipe, so as to realize the detection of rock and soil at different depths. Carrying out soil-borrowing operations, and such a soil-borrowing method will cause the operator to tap or remove the soil-borrowing tube when taking out the rock and soil in the soil-borrowing tube, and use a pole to remove the rock and soil in the soil-borrowing tube Push out, and then re-install the sampling cylinder to the sampler. This unloading method is cumbersome, time-consuming and labor-intensive, which seriously increases the labor intensity of the operator, and reduces the subsequent soil extraction efficiency, which is not easy to use.
