Description

The pile pulling device
Technical field
The utility model relates to a kind of pile pulling device, particularly relates to a kind of pile pulling device that residues in underground useless stake that is used to pull out.
Background technology
At present, along with transform the old town, factory's resettlement, road construction, especially construction of tunnel, a large amount of esidential buildings, old factory building, old road need to remove, and the stake of laying on has in situ just become useless stake, need in time it be pulled out, so that newly build.
For removing of these useless stakes, present way has following several: the one, adopt the method for pounding stake, promptly will play weight with equipment slings and pounds to useless stake, by pounding and extruding makes it to pulverize, displace disintegrating slag with thickened drilling fluid, pounded until whole useless stake and removed, whole process is time-consuming and cost is high, long in time limit, big to the influence of periphery, damage ratio is more serious; A periphery that will give up is exactly in addition squeezed into large diameter sleeve pipe and is entangled pile body, excavate the soil body in the sleeve pipe, extract the muddy water in the sleeve pipe, manually enter sleeve pipe, classification cuts pile body, extract pile body, also need extract outside steel sleeve then, this construction period is long, and labour intensity is big, the stacking of a large amount of soil bodys that dig out also is a problem, and it also is a high-risk operation that the workman cuts the earth at useless stake periphery; Another method directly drills through useless stake with imported large-scale equipment exactly, grinds pile body by force with the rig drill bit, and pulverize the back and extract disintegrating slag out with mud, this method cost height, the time is long, and is seriously polluted.
Chinese patent notification number CN2806566Y, a kind of steel bushing water vapor injection method pile pulling device is disclosed, it has a steel sleeve, has some through holes around the steel sleeve, vertically is fixed with one group of water conduit, airway at least along the outer wall of steel sleeve, water, airway are merged into one group of gas-vapor mix nozzle, this device promptly belongs to above-mentioned second kind of pile pulling method, and whole process is time-consuming and cost is high, and is long in time limit, influence to periphery is big, and damage ratio is more serious.
The utility model content
The purpose of this utility model is to provide a kind of pile pulling device of extracting that can will give up simply fast, and is long in time limit to solve the cost height that exists in the background technology, big to the influence of periphery, the problem that damage ratio is more serious.
To achieve these goals, the technical solution of the utility model is: a kind of pile pulling device comprise the sleeve pipe of tubular, but the bottom of described sleeve pipe is provided with the string bag of folding.When pressing down sleeve pipe with the vibrating hammer vibration, the string bag is in closed form, is positioned at the bottom of sleeve pipe bottom surface, can smoothly sleeve pipe be depressed into the position that is lower than useless stake, pull out sleeve pipe then, the string bag was subjected to useless stake or stopping of earth and was in deployed condition this moment, so just from a bottom of giving up it was caught, and was pulled out ground with sleeve pipe, this pile pulling device is simple to operate, cost is low, can not produce a large amount of mud, and is less to the pollution of environment.
As preferably, the described string bag comprises the steel bar of two circular arcs, and the two ends of described steel bar are all hinged with the bottom surface of sleeve pipe, and the bottom surface of steel bar and sleeve pipe is when fitting, and the steel bar internal diameter of circular arc is less than the internal diameter of sleeve pipe, and the circular arc inboard of described steel bar is provided with sawtooth.When pressing down sleeve pipe with the vibrating hammer vibration, steel bar all fits in the bottom surface of sleeve pipe, do not influence sleeve pipe, can smoothly sleeve pipe be depressed into the position that is lower than useless stake, pull out sleeve pipe then, this moment since the internal diameter of steel bar circular arc less than the internal diameter of sleeve pipe, and be subjected to useless stake or stopping of earth and rotate and be the expansion shape, so just the bottom from useless stake catches it, useless then stake is pulled out ground with sleeve pipe, be provided with sawtooth and then can become flexible useless stake soil layer on every side, earth and useless stake are broken away from, reduce to promote the resistance of pile pulling device.
As preferably, the described string bag comprises two laterally and two steel bars of circular arc longitudinally, the two ends of described steel bar are all hinged with the bottom surface of sleeve pipe, and when fit in the bottom surface of steel bar and sleeve pipe, the internal diameter of described two horizontal steel bar circular arcs is less than the internal diameter of sleeve pipe, and the inboard of two horizontal steel bar circular arcs is provided with sawtooth, described two longitudinally the external diameter of steel bar circular arc greater than the external diameter of sleeve pipe, and two longitudinally the outside of steel bar circular arc be provided with sawtooth.When pressing down sleeve pipe with the vibrating hammer vibration, steel bar all fits in the bottom surface of sleeve pipe, do not influence sleeve pipe and sink, can smoothly sleeve pipe be depressed into and be lower than useless position, pull out sleeve pipe on then, this moment is because steel bar is subjected to stopping to rotate and being the expansion shape of useless or earth, so just the bottom from useless stake catches it, and useless then stake is pulled out ground with sleeve pipe, is provided with sawtooth and then can becomes flexible soil layer around the useless stake, earth and useless stake are broken away from, reduce to promote the resistance of pile pulling device.
As preferably, described sleeve pipe cylinder bottom is provided with the ring-type sawtooth.Be provided with sawtooth and can become flexible useless stake soil layer on every side, earth and useless stake are broken away from, reduce to promote the resistance of pile pulling device.
The advantage of the utility model pile pulling device is: press down sleeve pipe to the position that is lower than useless stake with the vibrating hammer vibration, pull out sleeve pipe then, the string bag of sleeve bottom catches it from the bottom of useless stake, be pulled out ground with sleeve pipe, this pile pulling device is simple to operate, cost is low, can not produce a large amount of mud, and is less to the pollution of environment.
