Description

technical field

[0001] The invention belongs to the technical field of drilling technology, and mainly relates to the drilling technology for pile hole construction. Background technique

[0002] According to different conditions, piles can be divided into: vertical piles, horizontal piles, inclined piles; soil-squeezing piles, soil-stirring piles (such as powder-spraying piles, etc.), soil-discharging piles (such as non-squeezing soil bored piles, small amount of soil-squeezing bored piles, etc.); dry work piles, wet work piles; large width piles, medium width piles, thin piles; large diameter piles, medium diameter piles, small piles. The pile hole described in the present invention is a large diameter, large width, wet operation, soil discharge, vertical pile hole.

[0003] As a specialized branch of drilling technology, pile hole construction drilling is in its initial stage of formation. Therefore, the technical background of the present invention will be described be...
