Engineering geology deep soil sampling equipment

Abstract

The invention discloses engineering geology deep soil sampling equipment, and relates to the technical field of soil sampling, the engineering geology deep soil sampling equipment comprises a support, a sampling straight pipe is arranged in the middle of the support, the outer end of the sampling straight pipe is respectively connected with a moving frame and a shell from inside to outside, and the bottom end of the sampling straight pipe is provided with a base; the lower end of the base is slidably connected with a plurality of evenly-distributed soil scraping supports, the soil scraping supports can move to the outer side of the base in the direction away from the center position of the base, a vertically-through inclined groove is formed in the middle of each soil scraping support, and a soil scraping tool with the bottom end extending to the lower side of the corresponding soil scraping support is arranged in each inclined groove. The soil scraping device has the technical effects that the soil scraping support in an unfolded state can bear downward acting force applied by soil above the soil scraping support, so that upward counter-acting force borne by the soil scraping support in the soil cutting process is resisted, and the situation that equipment jumps and inclines due to the counter-acting force in the soil cutting process is avoided.

Description

technical field [0001] The invention relates to the technical field of soil sampling, in particular to an engineering geological deep soil sampling device. Background technique [0002] In the engineering and construction industry, it is usually necessary to sample and analyze the local soil before construction to achieve the purpose of geological exploration. [0003] Existing soil sampling equipment is mostly divided into vehicle-mounted equipment that is convenient for deep soil sampling and portable equipment that is convenient to move in complex terrain. In order to improve construction efficiency, it is impossible to conduct soil sampling after comprehensive leveling work in the construction environment. Therefore, when soil sampling needs to be performed at multiple points, portable soil sampling equipment is more convenient to use. [0004] In the prior art, the portable sampling equipment is usually stabilized on the ground in the form of triangular support, and th...

Problems solved by technology

[0003] Most of the existing soil sampling equipment is divided into vehicle-mounted equipment that is convenient for deep soil sampling and portable equipment that is easy to move in complex terrain. In order to improve construction efficiency, soil sampling cannot be performed after comprehensive leveling of the construction environment , therefore, portable soil sampling equipment is more convenient to use when soil sampling needs to be carried out at multiple points

[0004] In the prior art, the portable sampling equipment is usually stabilized on the ground in the form of a triangular support, and then the moving sampler goes deep into the soil. When the sampler digs down and goes deep into the soil, the upward reaction force on the sampler will It will cause the equipment to jump and tilt, which will affect the soil sampling work
