Building geotechnical investigation sampling device and use method

Abstract

The invention discloses a building geotechnical investigation sampling device and a use method, the building geotechnical investigation sampling device comprises a sampling box body, a combined drill rod and a blanking frame, support rods are arranged on two side walls in the sampling box body, and a fixed top plate is arranged at the top ends of the support rods. The device has the beneficial effects that the sampling box body is arranged, and universal wheels, the first hydraulic rod and the drilling motor are arranged on the sampling box body so that the design of miniaturization of large drilling equipment is realized, a worker can conveniently carry the drilling equipment for sampling when going out, and manpower is saved; the combined drill rod and the standby drill rod are arranged, and are mounted and used through the screwing studs and the combined mounting holes so that the drilling and sampling operation of rock and soil with different depths can be completed, and multi-aspect comparative analysis and research on samples are facilitated; and by arranging the discharging frame, the second hydraulic rod, the material receiving box and the buffering cushion, rock soil in the drilling barrel can be completely and safely discharged, the original pattern of the sample is kept, and the sample research precision is improved.

Description

technical field [0001] The invention relates to the technical field of geotechnical investigation, in particular to a sampling device for architectural geotechnical investigation and a method for using it. Background technique [0002] The purpose of geotechnical engineering investigation is to use testing means and methods to investigate, analyze and judge the construction site, to study the geological conditions of various engineering buildings and the impact of construction on the natural geological environment; During work, measures should be taken to ensure the strength and stability of the foundation and prevent it from inadmissible deformation; propose the bearing capacity of the foundation, provide the engineering address and geotechnical engineering data required for foundation design and construction, and foundation reinforcement when necessary. [0003] Most of the existing construction geotechnical survey and sampling devices are simple tools, which require more ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing construction geotechnical survey and sampling devices are simple tools, which require more manpower to operate and consume more energy. Moreover, the sampling depth cannot be selected, which is not conducive to the study of rock and soil at different depths. Secondly, the sampled soil is in the When unloading, it needs manpower to complete, and the process of taking out cannot keep the original state of the sample, which reduces the researchability of the sample
