The invention relates to the technical field of underground pipeline reconnaissance, and discloses a feeler inspection type underground pipeline probing shovel. The probing shovel comprises a feeler lever, a shovel head and a feeler inspection hammer moving vertically along the feeler lever. A leg base is protrusively arranged on the periphery wall of the feeler lever, the feeler inspection hammer is located above the leg base, the shovel head is located below the leg base, and the upper end of the shovel head is connected to a connecting end; groove rings and elastic clamping rings are arranged in a shovel cavity and distributed around the inner wall of the shovel cavity in the circumferential direction, in the direction from the top to the bottom of the shovel cavity, the diameters of the groove rings decrease progressively in sequence, the elastic clamping rings are in a circular ring shape with a fracture and arranged in the groove rings in a surrounding mode, and the height of the elastic clamping rings is smaller than that of the groove rings. The underground pipeline probing shovel has the advantages of being light, effective, wide in application range, small in error and high in safety and capable of penetrating buried depths of all underground pipelines and solving the problem of limited manpower, in addition, the dense state of a soil body can be evaluated according to blow counts when the probing shove penetrates into soil by a certain depth, and the problems that in the process of checking pipelines, sampling and in-situ test can not be carried out are solved.
Description
technical field [0001] The invention relates to the technical field of underground pipeline exploration shovels, in particular to a penetration type underground pipeline exploration shovel. Background technique [0002] Engineering survey is an important branch of geotechnical engineering. Its main purpose is to find out the engineering and hydrogeological conditions of the project construction site, find out the physical and mechanical properties of rock and soil, and provide rock and soil physical and mechanical parameters for design, so as to carry out foundation Design of foundations, foundation pit support and other related engineering issues. [0003] At present, the main source of danger in engineering surveys in cities lies in underground pipelines, including water supply pipes, drainage pipes, sewage pipes, rainwater pipes, power pipelines, communication cables, gas pipes, military cables, and various underground structures, such as underground boxes. Culverts, bas...
