Abstract

The invention discloses a method for cleaning a drill hole. The method comprises the following steps: S1, communicating a slurry inlet connector of a cyclone desander with a water outlet water head of a pile hole, and communicating a slurry outlet connector of the cyclone desander with a slurry pool; S2, feeding the slurry into the cyclone desander through the water outlet water head of the pile hole, wherein the slurry with certain pressure rotates in a mud-sand separation barrel; S3, separating out sand grains with large specific gravity through rotation and discharging the sand grains from a sand discharging opening, and feeding slurry with small specific gravity into the slurry pool from a slurry outlet; S4, pumping the slurry in the slurry pool after being fully mixed into the pile hole through a sewage pump and then feeding the slurry into the cyclone desander through the water outlet water head of the pile hole, and repeating the process; and S5, after the perfusion catheter is installed, repeating the steps S1 to S4 for secondary hole cleaning. The invention provides a method capable of efficiently and simply cleaning the drill hole.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for cleaning boreholes. Background technique [0002] Compared with the construction technology of prefabricated piles and manual excavated piles, the construction technology of bored piles is a pile foundation technology with low construction cost, simple construction operation, low vibration, low noise and small soil squeezing effect. Bored cast-in-place piles have the advantages of strong adaptability to geology, different pile-forming equipment for different geology, and mud wall protection piles can be used in areas rich in groundwater; therefore, bored piles construction technology has been widely used in construction projects construction field. However, the bored pile cannot be directly observed during the construction process. It is an underground concealed project, and excavation and acceptance cannot be carried out after the pile is completed, s...
