Abstract

The invention discloses a novel soil sampler which is composed of a ring cutter, a sampling tube, an end cover and a joint. The ring cutter is fixed at the bottom of the sampling tube, the end cover is sealed on the top of the sampling tube, and the joint is fixed on the top of the end cover. The ring cutter is inserted into the bottom of the sampling tube composed of two semicircular segments. The end cover is inserted into a tube cavity of the sampling tube and connected by a fixing screw, and the bottom surface of the end cover is provided with a cylindrical limiting groove. The surface ofthe end cover is provided with a venting hole communicated with the limiting groove, the top of the end cover is provided with a joint groove, and the joint is embedded in the joint groove. A throughhole is respectively opened in the central axes of the joint and the end cover, and the piston rod is inserted into the ring cutter through the through hole in the joint. A piston is fixed at the bottom of the piston rod. The bottom surface of the piston is flush with the bottom surface of the ring cutter, the top surface of the piston is provided with a limiting protrusion, and the outer diameterof the limiting protrusion is equal to the inner diameter of the limiting groove. The soil sampler is simple in structure, capable of preventing failure of sampled soil and preventing sampling failure caused by scattering of the sampled soil in the lifting process.

Description

technical field [0001] The invention relates to the technical field of exploration equipment, and in particular to a novel soil fetcher. Background technique [0002] In engineering geological prospecting and reconnaissance work, in order to obtain the physical and mechanical performance indicators of the foundation soil, it is necessary to insert the earth taker into the foundation at a certain depth to take out the undisturbed soil samples for analysis, so as to obtain the three-phase state parameters of the soil, and then provide the basis for the pile foundation. Calculations are provided for reference. Due to the shortage of urban land, the height of buildings has also increased, which also puts forward extremely high requirements on the bearing capacity of the foundation. Therefore, architectural survey has become an extremely important part. Parameters are critical to the stability of a building. [0003] During foundation investigation, it is necessary to use an au...
