Method for performing deep foundation pit waterproof curtain construction by adopting high-pressure jet grouting pile machine
The invention discloses a method for performing deep foundation pit waterproof curtain construction by adopting a high-pressure jet grouting pile machine. According to the method and for sludge, clayey soil, loess, sandy soil, artificial filling, a pebble bed, a mud rock layer and other geological layers large in pore-forming difficulty, a grouting pipe and a gas injection pipe are installed inside a CFG pile machine drill rod, a drill bit of a CFG pile machine is refit into a down-hole hammer drill bit, a construction technology that gunite pile forming is directly performed after pore forming is adopted, and constructive technical parameters are optimized, so that pore-forming quality is improved, a construction period is shortened, and construction cost is reduced.
