Soil stratified sampling preservation device for geological prospecting and use method

Abstract

The invention discloses a soil stratified sampling preservation device for geological prospecting and a use method, and relates to the technical field of the soil sampling equipment. The device is specifically composed of a soil exploration layer, an upper flat plate frame and a hollow transition block; a disk bracket is arranged on an upper surface of the soil exploration layer, a big circular groove is arranged in the middle of the upper flat plate frame, a hydraulic cylinder penetrates the internal of the big circular groove, an upper end of a hollow cylinder rod is arranged in the hollow transition block in a sleeve manner; a locating slot is formed on the surface of the hollow cylinder rod, fixed bolts are screwed at a left side and a right side of a threaded connecting rod, and a sliding rail is formed on an inner wall of the hollow cylinder rod. The simple assembling and disassembling can be performed between a support pillar and the upper flat plate frame, thereby facilitatingthe knocked-down shipping work of the device; secondly, three collection boxes are arranged on the device, the soil at different layers in the hollow cylinder rod corresponding falls in the collectionboxes, thereby performing stratified sampling on the soil.

Description

technical field [0001] The invention relates to the technical field of soil sampling equipment, in particular to a layered soil sampling and storage device for geological exploration and a method for using it. Background technique [0002] Geological prospecting is the investigation and research activities of conducting geological survey and detection through various means and methods, determining the appropriate bearing layer, determining the foundation type and calculating the foundation parameters according to the foundation bearing capacity of the bearing layer. When carrying out geological exploration, it is necessary to sample and analyze the soil at its location. Soil sampler refers to the tool used to obtain soil samples. Commonly used are soil drills, shovels and shovels. The soil drills are made of hard materials (steel or hard Plastic) drill bit and handle. [0003] However, the structure of the existing soil sampling device is too simple, and the soil layer is u...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a soil stratified sampling and preservation device for geological exploration and a method of use thereof, which solves the problem that the structure of the existing soil sampling device proposed in the above-mentioned background technology is too simple, and a drilling rig is usually used to carry out soil sampling. Broken, this kind of setting makes the soil of different layers in the soil mixed together, which is not conducive to the layered sampling of the soil. Secondly, the general soil sampling device is fixed and integrated, which is not conducive to the problem of splitting and carrying.
