Problems solved by technology

However, when the rotary drilling machine is used in the construction of the rock and soil layer with good cohesiveness, the artificial experience construction method is currently used. Various hole-forming failures are also prone to occur during drilling, resulting in damage to the components of the rotary drilling machine itself, which not only affects the progress of the project, but also causes great economic losses

Abstract

The invention is a dry earth drawing-hole forming construction process of a helical digging driller, comprising in turn site layout process, pile position templating process, helical digging driller seating process, steel sleeve burying process, drilling construction process, geologic condition recording process, hole forming checking process, residues cleaning process, etc, and having the characters of replacing traditional manmade experience construction method, needing no slurry to protect walls in the hole forming course, reasonable and convenient to operate, low operating cost, etc.

Description

technical field [0001] The invention relates to a construction technology of a dry soil-taking hole-forming method for a rotary drilling machine. The rotary drilling machine has the characteristics of large power, large output torque, large axial pressure, flexible maneuverability, high construction efficiency and multi-function. The rotary drilling machine is suitable for the soil and geological conditions in most areas of our country, and has a wide range of applications. It can basically meet the needs of bridge construction, high-rise building foundations and other projects. It is especially suitable for the dry (short spiral) hole-forming operation of the rotary drilling machine. Background technique [0002] Rotary drilling machine is a kind of construction machine suitable for hole forming in building foundation engineering, and is widely used in foundation construction projects such as municipal construction, highway bridges, high-rise...
