The specific embodiment
The present invention further specifies as follows in conjunction with specific embodiments:
A kind of hugging pressure type static-pressure driven cast-in-place pile job practices, the equipment that this method adopted is a kind of hugging pressure type static pressure, immersed tube stake machine, its general structure is referring to accompanying drawing 1, mainly comprise manipulation device 1, fuselage 2, walking mechanism 3, pile hoist crane 4, with folder stake and piling mechanism 5, the folder stake is that side is embraced stake of formula folder and piling mechanism with piling mechanism 5, referring to accompanying drawing 2, it is vertically fixed on the fuselage 2 by piling frame 9, there is vertical slide rail piling frame 9 inboards, be equipped with on the slide rail along on the slide rail, the pile clamping box 10 that slides down, piling frame 9 connects with pile clamping box 10 through piling oil cylinder 8, and the cylinder body of piling oil cylinder 8 is fixed on the piling frame 9, and the piston-rod lower end of piling oil cylinder 8 connects with pile clamping box 10, folder stake oil cylinder 11 is housed in the pile clamping box 10, folder stake oil cylinder 11 connects grip block 12, and clamping stake pipe 7 is referring to accompanying drawing 3.
Hugging pressure type static-pressure driven cast-in-place pile job practices of the present invention is to adopt above-mentioned hugging pressure type static pressure, immersed tube ram machine construction, mainly comprises the pile sinking pipe, inserts reinforcing cage, concrete perfusion, all operations of tube drawing pile, and referring to accompanying drawing 5, concrete implementation step is:
A), pile-forming machine perching: hugging pressure type static pressure, immersed tube stake machine is transported to the building site debug, operation pile hoist crane 4 is inserted in stake pipe 7 in the pile clamping box body 10, and operation folder stake oil cylinder 11 stretches out it again, drives the clamping that grip block 12 is realized stake pipe 7; Operate all-hydraulic walking mechanism 3, the order of walking mechanism by four supporting leg hoist cylinders and long and short shipping agency cooperates, and observes the omnirange level gauge that is contained on the operating desk panel, realize fast the leveling of stake machine with to stake;
