Problems solved by technology

[0004] The object of the present invention is to provide a rock soil sampling device for geotechnical engineering, aiming to solve the problem in the prior art that the contact between the sampling drill pipe and the rock and soil will cause the sampling drill pipe to vibrate, thereby making the sampled rock The sand and gravel in the soil are mixed during shaking, which affects the technical problem of sampling accuracy

Abstract

The invention discloses a geotechnical sampling device for geotechnical engineering, a vertical stand column is installed on the ground through a supporting device, a driving device drives a sampling drilling barrel to conduct rotary sampling, the sampling drilling barrel shakes with rock-soil in the sampling process, then a driving base is driven to shake, a horizontal supporting frame drives a guiding sliding block to slide up and down in the guiding sliding rail, the guiding sliding block extrudes the damping hydraulic rod in the sliding process, and the bottom of the damping hydraulic rod and the buffering piston slide in the buffering air cylinder together. Due to the fact that gas in the buffer air cylinder is extruded through sliding of the buffer piston, sliding of the guide sliding block is slowed down, shaking of the driving base and the sampling drill barrel is slowed down, the rock and soil sampling process of the sampling drill barrel is more stable, and gravel in sampled rock and soil is prevented from being mixed.

Description

technical field [0001] The invention relates to the field of geotechnical engineering, in particular to a rock soil sampling device for geotechnical engineering. Background technique [0002] At present, rock and soil include five categories: hard rock, soft rock, weakly connected, loose and unconnected, and special composition, structure, state and properties. [0003] In order to obtain the hard and soft rock and soil completely, the sampling equipment presses downwards to extend the sampling drill barrel into the rock and soil layer, and then takes out the rock and soil through the sampling drill barrel. However, during the sampling process In the process, the contact between the sampling drill barrel and the rock and soil will cause the sampling drill barrel to vibrate, and then the sand and stone in the rock and soil sampled will be mixed in the shaking, which will affect the accuracy of sampling. Contents of the invention [0004] The object of the present invention...
