Problems solved by technology

However, when the rotary drilling machine is used in the construction of loose and easy-to-collapse strata, strata with groundwater distribution, and unstable hole walls, manual construction methods are mostly used. The disadvantages are: it is very inconvenient to construct, and the rotary drilling machine is easy Various failures occur, and various hole-forming failures are prone to occur during hole formation, 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 discloses a method for static slurry protecting wall drilling hole molding of rotational hole driller, which comprises: area distribution, post sampling, removing blocks, digging protecting cylinder, inserting tube, drilling hole, embedding protecting cylinder, checking the position of post, measuring the mixing parameter of slurry, removing drilling slag, drilling a hole with driller, checking the hole diameter. The invention can replace traditional manual-experiment construction method which need slurry protective wall in the hole forming process. Wherein, the drilling head is moving between the hole bottom and the ground in the drilling process, with easy operation, simplified process and lower cost.

Description

technical field [0001] The invention relates to a static mud protection wall drilling method construction technology of 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 my 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 loose and easy-to-collapse areas with groundwater Pore-forming operations in formations with unstable distribution and pore walls. 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 suc...
