Rock-soil sampling mechanical device for civil engineering

Abstract

The invention relates to a rock-soil sampling mechanical device for civil engineering and belongs to the technical field of rock-soil analysis of civil engineering. The rock-soil sampling mechanical device comprises a top frame, a vertically arranged hydraulic telescopic rod whose upper end is fixedly connected with a bottom end of the top frame, a sampling pipe which is vertically arranged underthe top frame and is provided with sampling windows which are uniformly distributed at intervals from the top to bottom, a first rotating shaft which is vertically arranged and is rotationally arranged in the sampling pipe, a drill bit which is fixedly connected with a lower end of the first rotating shaft, and a first driving device which is fixedly connected to the top frame and is in transmission connection with an upper end of the first rotating shaft, wherein two ends of the first rotating shaft rotationally extend out of the sampling pipe. The rock-soil sampling mechanical device has theadvantages that hard rock in the soil can be drilled, the soil collection in deep soil can be facilitated, meanwhile, soil samples of different soil layers can be collected separately, and the soil sample analysis is facilitated.

Description

technical field [0001] The invention belongs to the technical field of civil engineering rock and soil analysis, and in particular relates to a rock and soil sampling mechanical device for civil engineering. Background technique [0002] Civil engineering is a general term for the science and technology of building various engineering facilities. Among them, in the actual engineering construction process, it is necessary to sample and analyze the composition of rock and soil, so as to facilitate the evaluation and design of construction projects. Therefore, the sampling of rock and soil is particularly important and critical. [0003] At present, there are many types of sampling devices, but due to the complex structure in the soil layer, there are often hard rocks and other substances in the soil layer, so most sampling devices can only drill soil samples in relatively shallow strata, and there is no way to drill. Into the deep soil, making it impossible to take deep soil...

[0003] At present, there are many types of sampling devices, but due to the complex structure in the soil layer, there are often hard rocks and other substances in the soil layer, so most sampling devices can only drill soil samples in relatively shallow strata, and there is no way to drill. Into the deep soil, resulting in the inability to collect deep soil samples, resulting in poor collection of soil samples and inaccurate analysis of soil components
