Fig. 3 is use state diagram of the present utility model.
Fig. 4 is the block diagram that while adopting the utility model, pile body is shaped.
The specific embodiment
As Fig. 1, shown in 2, integrated long helix extruding-enlarging bored pile piling device described in the utility model, comprise the auger stem 2 with long spiral drilling head 1, on the auger stem near long spiral drilling head 1 place, be connected with squeezed device, this squeezed device comprises the concrete pipe 5 with upper adpting flange 3 and lower adpting flange 4, at the middle part of concrete pipe 5, perpendicular to concrete pipe direction, be arranged in order up and down that to be provided with upper and lower two of the hydraulic jack 6(that four direction is contrary be one group, middle two is one group), as required, hydraulic jack 6 can be only two, also can a plurality ofly be one group of setting.Hydraulic jack 6 can be single-unit oil cylinder, also can be telescopic cylinder, in the piston rod end of upper and lower two hydraulic jacks, be connected with left squeezed plate 7, in the piston rod end of middle two hydraulic jacks, be connected with right squeezed plate 8, left squeezed plate 7 and right squeezed plate 8 measure-alike; On piston rod, dirt-proof boot can be set with, certain dustproof effect can be played.
Hydraulic jack can be also an independently cylinder body simultaneously, and through hole is offered in centre, is communicated with upper and lower concrete pipe, and middle part is divided into the oil cylinder of two groups of symmetrical opposite directions by dividing plate, can realize this function, can also reduce the volume of hydraulic jack.
For improving the squeezed ability of squeezed device, on the concrete pipe of hydraulic jack both sides Shang Xia 6, be respectively installed with the upper support arm 9 and the lower support arm 10 that move up and down, the two ends of upper and lower support arm are articulated as one by passive support arm 11 and the two ends up and down of left squeezed plate 7 and right squeezed plate 8 respectively, and the passive support arm 11 that symmetrically arranged upper support arm 9 and lower support arm 10, bilateral symmetry are hinged and a left side squeezed plate 7 hinged with it and right squeezed plate 8 be common forms squeezed arm.
For guaranteeing that upper and lower support arm rotates moving up and down Shi Buhui, in the trepanning of upper support arm 9 and lower support arm 10, be fixedly installed the slip ring with guide groove, on concrete pipe, be provided with the raised line matching with this guide groove, during work, the guide groove on upper support arm 9 and lower support arm 10 trepanning slip rings slides up and down along the raised line arranging on concrete pipe.Equally, guide groove also can be opened on concrete pipe, and raised line is just arranged in slip ring, and function is identical.
