Rock-soil sampling mechanical device for civil engineering

Abstract

The invention discloses a rock-soil sampling mechanical device for civil engineering, which comprises a mounting frame, a support plate and a vertical linear slide rail, and the support plate can slide along the vertical linear slide rail; the mechanical device also comprises a sliding mechanism which is arranged at the upper end of the supporting plate, and a drilling and sampling mechanism whichis arranged below the supporting plate. The drilling and sampling mechanism comprises a pile casing and a strip-shaped guide hole; the strip-shaped guide hole is communicated with the inner cavity ofthe pile casing; a baffle is arranged in the pile casing; the interior of the pile casing is divided into upper and lower cavities; a sliding rod is arranged in the upper cavity; the bottom of the sliding rod is in sliding connection with a baffle through a moving guide mechanism. The top of the sliding rod penetrates through the strip-shaped guide hole to be in sliding connection with the sliding structure, a plurality of sampling assemblies are arranged on the sliding rod in the height direction of the sliding rod, a plurality of sampling openings matched with the sampling assemblies are formed in the side wall of the pile casing in the height direction of the pile casing, and a first driving motor and a drill bit assembly are arranged in the lower cavity. Through cooperation of the sliding mechanism and the moving guide mechanism, sampling of different rock-soil layers is realized.

Description

technical field [0001] The invention belongs to the field of civil engineering devices, in particular to a rock 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. It refers to the materials, equipment, technical activities such as survey, design, construction, maintenance and repair, as well as the object of engineering construction, that is, the construction in Various engineering facilities on the ground or underground, on land or in water, directly or indirectly serving human life, production, military affairs and scientific research, such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, power stations, aircraft Fields, offshore platforms, water supply and drainage, and protection projects, etc. Civil engineering refers to the survey, planning, design, and construction of buildings, structures, and ...

AI Technical Summary

Problems solved by technology

[0004] Existing soil extractors for civil engineering sampling are mostly used to pull out after entering the soil rock layer by turning the head when sampling the soil. In this way, when the storage chamber is pulled out, part of the internal soil will fall under the action of gravity or other factors, so that when studying the soil stratification, and It is impossible to see the soil stratification more intuitively and specifically, which makes the original mechanical separation rock-soil device for civil engineering sampling have certain limitations in the process of use.
