Soil obtaining device special for construction soil detection

Abstract

The invention relates to the technical field of soil detection equipment, and discloses a soil obtaining device special for construction soil detection. The soil obtaining device comprises a rigid supporting sleeve, a connecting disc sleeves the middle of the rigid supporting sleeve through threads, and a threaded pipe sleeve is fixedly connected to the top of the connecting disc; an adjusting handle is arranged on one side of the top of the threaded pipe sleeve, and a soil sampling probe located below the rigid supporting sleeve is fixedly connected to the bottom of the connecting disc; evenly distributed soil obtaining grooves are formed in the periphery and the top of the soil sampling probe respectively. According to the soil obtaining device special for construction soil detection, three groups of auxiliary supporting devices and positioning devices are in pin connection with the ground at the same time, so that it is guaranteed that the upper end and the lower end of the whole device is fixed at the same time in the soil obtaining process, when drilling is carried out, the device cannot incline, the perpendicularity of a drill rod moving downwards is guaranteed, then soil indifferent soil layers can be conveniently taken out, the soil obtaining uniformity is improved, and accurate measurement data can be obtained conveniently.

Description

technical field [0001] The invention relates to the technical field of soil testing equipment, in particular to a special soil-taking device for construction soil testing. Background technique [0002] The earth taker is used to lift the undisturbed soil of the lower layer of the test soil as a sample to understand its properties. In order to understand more about the properties of the base, and in engineering geological exploration and survey work, in order to obtain the physical and mechanical performance indicators of the foundation soil, sometimes even To take the original soil at a deeper level, and this soil-taking equipment is called a soil-taking device. [0003] In engineering geological prospecting and reconnaissance, in order to obtain the physical and mechanical performance indicators of the foundation soil, in addition to in-situ testing, the indoor geotechnical experiment after drilling and sampling is mainly used. To obtain undisturbed soil samples close to t...

AI Technical Summary

Problems solved by technology

[0010] Aiming at the deficiencies of the prior art, the present invention provides a special soil-taking device for construction soil detection, which has good stability, better soil distribution uniformity, accurate detection results, electric drive, and more convenient and labor-saving soil-taking process. and other advantages, it solves the problem that the driving of the drilling rod is artificially driven. Since the underground situation is position-dependent, it will encounter the problem of hard geology when drilling. The artificial driving is more laborious, and the stability of the device cannot be guaranteed. The process of taking soil will cause the deviation of the device, which will result in poor uniformity of the soil taken out and affect the accuracy of detection.
