Abstract

The invention provides a sampling device for civil engineering rock-soil detection, which belongs to the technical field of rock-soil detection and comprises a support frame, a sampling unit and two groups of power units, the sampling unit comprises a sampling cylinder, an auger stem and a rotary motor; sliding parts are arranged on the inner sides of the supporting frames, the two ends of each sliding part are slidably connected with the supporting frames, motor protection boxes are arranged at the bottoms of the sliding parts, rotating motors are arranged in the motor protection boxes, sleeves are arranged at the bottoms of the motor protection boxes, the upper ends of sampling cylinders are in threaded connection with the sleeves, and blades are arranged at the lower ends of the sampling cylinders in the circumferential direction; the two power units are symmetrically arranged on the two sides of the top of the supporting frame, each power unit comprises a lifting motor, a first bevel gear, a second bevel gear, a rotating shaft, a straight gear, a force application rod and a rack, the lifting motors are arranged on the top of the supporting frame, and the power units are used for driving the sampling units to move vertically. The device can control the height of the sampling unit through the power unit, so that the sampling depth is conveniently adjusted, and the sampling barrel is pulled out.

Description

technical field [0001] The invention belongs to the technical field of geotechnical detection, and in particular relates to a sampling device for geotechnical detection in civil engineering. Background technique [0002] Rock and soil is a general term for any kind of rock and soil that makes up the earth's crust from the perspective of engineering and construction. Rock and soil can be subdivided into five categories: hard (hard rock), semi-hard (soft rock), weakly connected, loose and unconnected, and with special composition, structure, state and properties. People are used to referring to the first two categories as rocks, and the last three categories as soil, collectively referred to as "rock and soil". Before various constructions, it is very important to collect samples of rock and soil and detect the basic properties of rock and soil, which has an important guarantee for the quality of construction. [0003] To sample rock and soil, a sampling device is essential....
