Problems solved by technology

The disadvantage is that due to the vibration construction method and soil squeezing effect, the embankment or dam body is easy to crack, deform and lose stability, resulting in engineering quality problems, and the vibration will also have a certain impact on the surrounding environment.
The disadvantage of this technology is that the mixing of cement and soil is not uniform, and the construction quality is not easy to control, resulting in insufficient strength of the pile body and lack of anti-seepage effect. In addition, the treatment depth of this technology is also limited, generally less than 15 meters
Also there is the same defective in above-mentioned two kinds of methods, promptly inefficiency, labor-intensive and time-consuming

Abstract

The present invention relates to a multithread minor diameter long auger drilling wall forming machine. Said invention adopts portal shaped piledriver side-by-side set at least auger stems, lower end set drill, top connected with spacer, spacer slip connection with portal shaped piledriver, spacer set rotating power unit, auger stem connected with rotating power unit, auger stem being hollow in middle part, connected with concrete delivery pipe, guideway set below the chassis. Said invention solves uneven soil stirring, weak intensity, inefficiency etc shortage.

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...
