Description

technical field

[0001] The invention relates to a novel auger drilling wall-forming machine, in particular to a multi-head small-diameter long auger drilling wall-forming machine. Background technique

[0002] Before the present invention, in the engineering anti-seepage wall constructions such as embankment, earth dam, the thin-wall anti-seepage wall of vibratory sinking formwork and multi-head small-diameter deep-stirring pile thin-wall anti-seepage wall are commonly used technologies. Vibration sinking thin-wall anti-seepage wall technology is to drive the thin-walled H-shaped hollow formwork into the ground by vibration, and then pour grout or concrete into it to form a unit anti-seepage plate. The construction process of the wall is simple, the quality is easy to control, the anti-seepage performance is good, and the treatment depth can reach more than 30 meters. The disadvantage is that due to the vibration construction method and soil squeezing effect, the embankment...
