Abstract

The invention discloses a construction method of a spiral percussion drilling device suitable for rock and soil. The drilling device includes a drilling machine system and a drilling machine support. The drilling machine support includes a walking chassis mechanism. The chassis mechanism is provided with a rotating mechanism. There is a working platform on the top, and a driving and operating room is set on the working platform. The front end of the working platform is equipped with a boom, and the front end of the boom is connected to the drilling system; the drilling system includes power distribution system, air pressure system, and rock drilling components. , earth drilling components, gears, drill pipes and bits. The construction method includes driving the drilling rig support to the designated position; installing the drilling system; adjusting the initial height and drilling angle of the drill bit; and starting drilling. The invention solves the problem that the drilling equipment cannot be applied to different soil layers, and the helical percussion drilling device suitable for rock and soil can adapt to different stratum conditions, can precisely control the drilling angle, has strong mobility, is environmentally friendly, saves energy and reduces Noise, the drill bit is solid and reliable, suitable for slope and foundation pit support projects.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to a construction method of a spiral percussion drilling device suitable for rock and soil. Background technique [0002] Bolt support is a common form of support in the field of geotechnical engineering. Usually, the soil layer is drilled with an auger drill, and the rock layer is drilled with percussion down-the-hole drilling. In actual engineering, complex formations with both soil and rock formations are often encountered. The conventional solution to such problems is to replace drilling equipment. However, there are following problems in this type of solution: (1) the replacement, transportation, assembly, and check of machine tool equipment take a lot of time and increase the construction period. (2) Replacement of different drilling equipment according to different formation conditions will increase the engineering cost virtually. (3) The replac...
