Anti-pollution geotechnical investigation sampling equipment for building design and geotechnical investigation method

Abstract

The invention discloses anti-pollution geotechnical investigation sampling equipment for building design and a geotechnical investigation method, and relates to the technical field of geotechnical investigation sampling devices. The anti-pollution geotechnical investigation sampling equipment comprises two supporting frames, a pair of connecting plates are installed on the side walls of one sides of the two supporting frames, sliding grooves are formed in the tops of the two supporting frames, and a sliding plate is arranged between the two supporting frames; the two ends of the sliding plate are located in the two sliding grooves, and an L-shaped plate is installed at the bottom of the sliding plate. The equipment is reasonable in structure, a water-soil mixture is sucked into the annular groove through the multiple drainage holes and discharged into the water tank through the water pump, the situation that the water-soil mixture enters the outer pipe shell from the bottom of the drill bit, and consequently rock and soil in the outer pipe shell are polluted is avoided, and the first pressing spring always presses the pressing pipe, so that the pressing pipe is always attached to the surface of the rock and soil; other impurity rock soil on the outer side of the drill bit is further prevented from entering the outer pipe shell from the drill bit, it is ensured that the rock soil is not polluted during sampling, and the rock soil sample analysis accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of geotechnical survey and sampling, in particular to a geotechnical survey sampling device and a geotechnical survey method for anti-pollution architectural design. 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. Geotechnical investigation and sampling devices are required to analyze the rock and soil bef...

Problems solved by technology

[0004] The above-mentioned existing rock and soil survey and sampling device has a simple structure and a single function. The sampling device can only take out the rock and soil, and no anti-pollution structure is installed, so that the rock and soil sample taken out is polluted, which affects the analysis results. Therefore, this The application proposes an anti-pollution architectural design with geotechnical survey and sampling equipment to solve the above technical problems
