The invention relates to the field of geological investigation and particularly relates to an environment-friendly sampling device for geotechnical engineering investigation. The environment-friendly sampling device for geotechnical engineering investigation comprises a sampling pipe, a bottom plate, a driving device, an impact cylinder, a clamping assembly and a reset device, wherein the sampling pipe is sleeved with the impact cylinder, the driving device is configured to drive the impact cylinder to ascend by a preset height so that the impact cylinder freely falls; the clamping assembly is located at a preset distance under the impact cylinder; the sampling pipe penetrates through the clamping assembly, and the impact cylinder is coaxial with the sampling pipe when being located at the highest position; the clamping assembly clamps the sampling tube under the impact of the impact cylinder; the reset device comprises a supporting rod and a first compressed spring, the first compressed spring is horizontally installed on the bottom plate, one end of the supporting rod is connected with the first compressed spring, the other end of the supporting rod is connected with the clamping assembly, and the first compressed spring enables a lower end of the supporting rod to abut against the bottom plate in the initial state, so when the impact cylinder impacts the clamping assembly, the clamping assembly clamps the sampling pipe and then synchronously moves downwards along with the impact cylinder; and energy loss of the impact cylinder is reduced.
Description
technical field [0001] The invention relates to the field of geological survey, in particular to an environment-friendly sampling device for geotechnical engineering survey. Background technique [0002] In the prior art, it is necessary to use sampling devices to collect rocks and soils at different depths during geotechnical engineering investigation. The existing sampling device is to drive a hollow sampling tube into the ground to a certain depth and then take it out. Therefore, in order to obtain rock and soil samples in deep underground layers, the length of the sampling tube often needs to be longer. The existing sampling device uses the method of hitting the top of the sampling tube to drive the sampling tube into the ground, but when the length of the sampling tube is long , this kind of hitting method is inconvenient to operate, so a sampling device that can adapt to different sampling tube lengths is needed to meet the sampling requirements of rock and soil at dif...
