Abstract

The invention discloses a stirring device for a bidirectional stirring pile machine and a using method, the stirring device comprises a suspension mechanism, a stirring mechanism and a driving mechanism, the driving mechanism comprises an upper power head, a lower power head and a lifting assembly for driving the lower power head to be close to or away from the upper power head; the stirring mechanism comprises a drill rod assembly and a bidirectional stirring drill bit which are axially connected, the upper power head is connected with an upper output shaft used for being connected with the upper end of an inner drill rod unit of the drill rod assembly, and the lower power head is connected with a lower output shaft used for being connected with the upper end of an outer drill rod unit of the drill rod assembly. The lower end of the upper output shaft is slidably arranged in an inner hole of the lower output shaft in a penetrating mode. According to the stirring device for the bidirectional stirring pile machine and the installation method, accurate and stable installation of the inner drill rod and the outer drill rod of the drill rod assembly can be achieved, installation is convenient, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of stirring pile machines, in particular to a stirring device for two-way stirring pile machines. Background technique [0002] Compared with the one-way mixing pile driver, the two-way mixing pile driver has higher efficiency, uniform mixing, and better pile quality, and is highly praised by the geotechnical engineering field. However, most of the mixing pile machines currently used in the market are one-way mixing pile machines, which take a long time to form piles and are difficult to guarantee the quality of piles. When constructing large-depth and large-diameter mixing piles, it is difficult to output two-way high torque, which greatly limits the application of two-way mixing technology. In addition, the installation and disassembly of the bidirectionally rotating drill pipe and the corresponding dual power heads of the bidirectional mixing pile machine is very complicated, and there are many installat...
