Background technology
The static-pressure driven cast-in-place pile engineering method is a kind of novel pile foundation construction technology, and this job practices is to utilize filling pile machine of static-pressure immersed will be with the pile cover steel pipe to be pressed into ground, and then concrete perfusion inserts reinforcing cage, and then steel pipe is extracted in vibration.This construction method pile quality is high, and is applied widely, uses more and more wider.But because the hopper of the concrete perfusion that uses in this job practices does not at present have automatic exhaust device, so that during concrete perfusion, the air in the steel pipe is difficult to discharge, and affects construction quality and efficient.
Summary of the invention
Technical problem to be solved in the utility model is: in the static-pressure driven cast-in-place pile work progress in the above-mentioned prior art during concrete perfusion, air in the steel pipe be difficult for to be discharged and is affected the deficiency of construction quality and efficient, and a kind of automatic vent magazine attachment is provided.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of automatic vent magazine attachment, formed by lifting arm and hopper, be characterized in: this lifting arm is hollow structure, the top is provided with hanger, the below of hanger is provided with exhaust opening, and the bottom of this lifting arm is provided with port, and is provided with annular slab; This hopper comprises the upper and lower, and this top is cylindrical drum, and the bottom is taper cone barrel, the upper end on top is provided with cross-arm, and the cylindrical drum inwall is fixed at the two ends of this cross-arm, and the central authorities of this cross-arm are provided with steel pipe socket, this lifting arm is installed in this steel pipe socket, and can slide up and down in steel pipe socket; The lower end of bottom has circular injected hole, and the annular slab of this injected hole and lifting arm matches to open or close hopper.
Described annular slab is provided with endoporus, and the inner hole sleeve of this annular slab is located at the port outside of lifting arm.
Be welded with reinforcing rib between described annular slab and the lifting arm.
The top of described hopper is provided with the reinforcing ring that the cross-arm two ends are reinforced.
The beneficial effects of the utility model are, adopt this automatic vent magazine attachment, during concrete perfusion, hopper can be placed on the immersed tube steel pipe top safely, as long as the suspension hook of loop wheel machine is slowly transferred, lifting arm can descend automatically, injected hole is opened, concrete promptly is injected in the immersed tube steel pipe, air in the immersed tube steel pipe enters in the lifting arm exhaust opening through top by the port of lifting arm bottom and automatically discharges, thereby automatic vent when realizing perfusion has reduced the filling concrete difficulty, improve the pile driving construction quality, improved efficient and the safety of construction.This apparatus structure is simple, making, installation, use, convenience easy to maintenance.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings
