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.
