Civil engineering intelligent exploration sampling device for airport pavement

Abstract

The invention relates to the technical field of exploration sampling, in particular to a civil engineering intelligent exploration sampling device for an airport pavement. The civil engineering intelligent exploration sampling device for the airport pavement comprises a driving mechanism, an outer cylinder, a coring cylinder and a coring mechanism. The coring mechanism comprises an annular spring, a plurality of pieces of elastic blocking cloth, a locking mechanism, a drilling disc, a plurality of connecting rods, a connecting mechanism and a plurality of extruding and pushing tables. When the outer cylinder rotates clockwise and is inserted downwards into soil, the drilling disc rotates anticlockwise, then rotates clockwise and moves upwards until the first end part of the connecting rod is in contact with the upper surface of the drilling disc, and the connecting drilling disc is connected with the outer cylinder; and the outer cylinder is configured to enable the locking mechanism to be unlocked when the first end part of the connecting rod is in contact with the upper surface of the drilling disc and then stops rotating and only moves downwards, so that the annular spring pulls the first end part of the connecting rod to swing inwards to abut against the sandy soil, and then when the outer cylinder rotates again, the first end part of the connecting rod further swings inwards to unfold the elastic blocking cloth.

Description

Technical field [0001] The present invention relates to the field of exploration and sampling, and specific relates to a civil engineering intelligent exploration sampling device for airport surface. Background technique [0002] Civil Engineering is the scientific technology of all kinds of engineering facilities. It is necessary to sampling the soil before the construction of the airport, so that the construction project is evaluated and designed, so the sampling of the soil is especially important and critical. The traditional dirt is sampling, the sampling soil cannot be just the soil of the surface, and it is necessary to sample the soil depth, so it is necessary to dig the pit, sample the soil below, so it needs to carry a lot of tools, while adopting This way also destroys the geomorphology and takes a lot of human and material power. And the soil that encounters loose sand in geological detection is often easily obtained, it is easily broken, and there is no reduction of ...
