Abstract
The utility model discloses an underground pile removing apparatus with a door plate clamp. The underground pile removing apparatus with the door plate clamp comprise a sleeve. The underground pile removing apparatus with the door plate clamp is characterized in that the bottom of the sleeve is evenly distributed with multiple bottom doors along a side wall circumference; each bottom door is hinged with a door plate clamp; and the door plate clamp can turn over toward the sleeve and is at a horizontal supporting state. The bottom door is arranged on the sleeve bottom; when a broken pile is present or steel reinforcement cage is in shortage, the door plate clamp can be installed on the bottom door; after the installation of the door plate clamp, the casing pipe top is clamped by vibratory hammer; davit of crane sinks slowly to a middle and close to the lower part of the pile or a pile bottom; the door plate clamp stretches out to a horizontal supporting state on the pile bottom, so that pile bottom is held; air and water charging operation is performed for two or three minutes; stress is slowly applied to the crane until the pile is loosened; and then after the pulling force is reduced, the whole pile casing is lifted up, so that the whole pile is removed.
Description
Technical field
The utility model relates to field of civil engineering, specifically a kind of plucking device for removing the obstructions such as the residual castinplace pile of underground soil layer, preformed pile, pile for prestressed pipe, underground residual old steel concrete, piece stone.
Background technology
In subway construction; shield machine advances operation often can run into the various engineering piles that old building carries over; stop the propelling of shield structure; must pull out it; in the engineering pile of leaving over, some engineering pile does not stay any engineering design, construction information owing to building the age early; the data such as the layout of the front engineering pile foundation of pile pulling construction, quantity, degree of depth length of reinforcing cage etc. all have no data available, and have so just increased the difficulty of processing stake.Existing job practices commonly used is to adopt full-sleeve double fluid high-pressure jet, jetting vibration, immersed tube clear hole method pile pulling to solve above problem, but can run into no-reinforcing-bar cage phenomenon bottom pile body fracture and pile body in actual withdrawal process, and the pile pulling device that uses in above-mentioned pile pulling method can't solve problems, causes temporal waste.
The utility model content
The utility model provides a kind of underground pile foundation plucking device for fear of the weak point that prior art exists, and this device can effectively be pulled out broken pile, residual pile body.
The utility model technical solution problem adopts following technical scheme:
A kind of underground pile foundation plucking device that is provided with the door-plate folder, comprise sleeve, its design feature is, the bottom of described sleeve circumferentially is evenly distributed with a plurality of bottom doors along sidewall, is hinged with on described bottom door and to be in the door-plate folder of horizontal support state to upset in sleeve.
The utility model design feature also is:
The sleeve lateral wall that is positioned at bottom door left and right side is provided with the rotating shaft engaging lug, and described door-plate folder is movably connected on engaging lug by rotating shaft.
Described rotating shaft and engaging lug, door-plate folder removably connect.
Described bottom door is three.
The length of described door-plate folder be sleeve diameter 1/3 to 1/2 between.
Compared with the prior art, the utility model beneficial effect is embodied in:
The utility model arranges bottom door bottom sleeve, when running into broken pile or no-reinforcing-bar cage, the door-plate folder is installed on bottom door, after installing the door-plate folder, the recycling vibrating hammer is clamped the sleeve pipe top, crane hangs slowly vibration-sunk to remaining position, pile body lower middle or pile body bottom, and door-plate is clipped in the open and flat one-tenth horizontal support state in pile body bottom, thereby carries the stake bottom; Then begin not stop the inflation bath after 2,3 minutes, slowly make loop wheel machine afterburning, until pile body is loosening, pulling force is directly mentioned whole casing after descending, and just whole pile body can be pulled out.

Fig. 2 is the utility model sleeve and door-plate holder mounting structure schematic diagram.
Fig. 3 is the utility model sleeve bottom door part-structure schematic diagram.
Fig. 4 is the utility model door-plate clamping structure schematic diagram.
Number in the figure: 1 sleeve, 2 door-plate folders, 3 engaging lugs, 4 bottom doors, 5 rotating shafts.
The specific embodiment
Technical solutions of the utility model are done further by the specific embodiment below in conjunction with accompanying drawing and explained.
As shown in the figure, the pile foundation plucking device, comprise sleeve 1, sleeve 1 evenly is provided with a plurality of through holes vertically, the mixing spraying mechanism of inject high pressure gas, water under high pressure in the outer wall of sleeve is provided with from sleeve bottom to sleeve, injection equipment comprises sparge pipe, air jet pipe and nozzle (more than be existing structure, do not provide corresponding structure in figure); Bottom at sleeve circumferentially is evenly distributed with a plurality of bottom doors 4 along sidewall, is hinged with on bottom door also to be in to upset in sleeve the door-plate folder 2 of horizontal support state.
During concrete enforcement, bottom door 4 is more than three or three, and the sleeve lateral wall that is positioned at bottom door left and right side is provided with engaging lug 3, and the door-plate folder is movably connected on engaging lug 3 by rotating shaft 5; Rotating shaft 5 removably connects with engaging lug 3, door-plate folder 2.The length of door-plate folder 2 be sleeve diameter 1/3 to 1/2 between.
The pile pulling device construction method step:
(1) make steel sleeve according to long 1 metric system of adding of stake in advance, after machining sleeve pipe, connect the high-pressure water pipe tracheae to the sleeve pipe top, vibrating hammer is clamped the sleeve pipe top, and the 150t crawler crane lifts by crane sleeve pipe is slowly erect.
(2) vibrating hammer is opened by locating sleeve centrally aligned pile center, and sleeve pipe is shaken in the soil body, opens simultaneously the high-pressure water gas device in the process of shaking, and auxiliary sleeve pipe sinks, until sleeve opening is flat with the stake top.Repeated multiple times lifting sinks pile body and the soil body are broken away from fully.
(3) remove vibrating hammer, at pile crown downward 1.5 meters, wire rope is installed, loop wheel machine lifting bowden cable, the lasso trick pile body of tying tight, under the effect of high-pressure water gas, because pile body separates with the soil body, loop wheel machine only need overcome the pile body own wt can hang out sleeve pipe with pile body.
(4) when running into broken pile or no-reinforcing-bar cage pile foundation, for the pile body that remains in sleeve pipe, again sleeve pipe is mentioned, at sleeve pipe bottom installation door-plate folder, utilize vibrating hammer to clamp the sleeve pipe top, crane hangs slowly vibration-sunk to remaining position, pile body lower middle or pile body bottom, and door-plate is clipped in the pile body bottom and rotates open and flat one-tenth horizontal support state by vertical state, thereby carries the stake bottom; Then begin not stop the inflation bath after 2,3 minutes, slowly make loop wheel machine afterburning, until pile body is loosening, pulling force is directly mentioned whole casing after descending, and just whole pile body can be extracted.When getting, must utilize crane sleeve being carried to be put in ground local stably, first the door-plate pin be dismantled, after taking away three door-plates, slowly mention sleeve and possible rotation crane, broken pile is fallen down stably, accomplish safety, effectively construction.
