Problems solved by technology

[0002] Traditional engineering geological survey equipment often uses drilling or hoisting hammer to lift and impact the soil to press down the soil when sampling soil. However, the existing technology often involves circulating water or mud when drilling and taking soil. The soil is polluted before the sample is taken out, which affects the representativeness of the soil sample taken out, and the way of hoisting and impacting is extensive, which has certain potential safety hazards

Abstract

The invention provides a directly-pushing type soil sampling drilling tool assembly. The directly-pushing type soil sampling drilling tool assembly comprises an impact holding shaft, an impact inner tube, an impact outer tube, a sampling tube and a drill bit. The sampling tube is connected with the bottom end of the impact inner tube. The drill bit is connected with the bottom end of the impact outer tube. The impact outer tube is arranged on the outer sides of the sampling tube and the impact inner tube in a sleeving mode, wherein the sampling tube and the impact inner tube are connected together. The drill bit is hollow and communicates with the bottom end of the sampling tube. The impact holding shaft is mounted at the top end of the impact outer tube. The directly-pushing type soil sampling drilling tool assembly can avoid formation of earth-surface wound surface, sampling is convenient, and secondary pollution of samples can be avoided.

Description

technical field [0001] The invention relates to geological survey equipment, in particular to a direct-push soil sampling drilling tool assembly. Background technique [0002] Traditional engineering geological survey equipment often uses drilling or hoisting hammer to lift and impact the soil to press down the soil when sampling soil. However, the existing technology often involves circulating water or mud when drilling and taking soil. The soil is polluted before the sample is taken out, which affects the representativeness of the soil sample taken out, and the way of hoisting and impacting is extensive, which has certain potential safety hazards. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a direct-push soil sampling drilling tool assembly, which can not only avoid the formation of surface wounds, facilitate sampling, but also avoid secondary pollution of samples. [0004] According to the technical...
