Description

Technical Field

[0001] The utility model application relates to the technical field of drilling devices, in particular to a drilling device for measuring rock and soil permeability. Background Art

[0002] Rock permeability refers to the water-permeability capacity of rock pores and cracks under the action of water (or fluid) pressure. It has an important influence on the stress and stability of the rock mass. It is closely related to the crack occurrence, distribution density, crack aperture, connectivity, the presence or absence of fillings, and changes in stress state. When measuring rock permeability, it is necessary to drill a hole and observe the water seepage state deep in the rock.

[0003] When using the existing drilling devices for measuring rock and soil permeability, the drill rig is directly moved to the drilling point, and the drill bit is aligned before drilling. However, since the terrain of the bottom of most rocks is irregular when drilling rocks, the drill rig needs to be handheld during drilling, which makes the operation very laborious and dangerous.
