Civil engineering intelligent exploration sampling device for airport pavement

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 f
