Abstract
One kind button tubular type pile extractor, is related to civil engineering equipment technical field, and what is solved is the technical problem for reducing construction cost and shortening the construction period.The pile extractor includes button and managed, and is hubbed at four pile pulling fixture blocks that can be pivoted up and down of button inside pipe wall bottom；The button pipe is the straight tube that upper and lower ends open, and four pile pulling fixture blocks are symmetrically laid along the circumferential of button pipe, and the inner wall lower for detaining pipe is fixed with four limit card blocks, and four limit card blocks are laid in the underface of four pile pulling fixture blocks respectively；When each pile pulling fixture block is switched to length direction perpendicular to the central axis of button pipe, the pile pulling fixture block props up the limit card block immediately below it, and the inner of the pile pulling fixture block is located at the inner side of the limit card block.Pile extractor provided by the utility model, suitable for pulling out the waste and old pile tube being embedded in the soil body.
Description
Technical field
Civil engineering equipment and technology is the utility model is related to, more particularly to a kind of technology for detaining tubular type pile extractor.
Background technology
During civil engineering, it is often necessary to remove waste and old pile pipe originally embedded in the soil body.Existing waste and old pile pipe
Sweep-out method mainly has two kinds：One kind is water drawn and iron stake method, and this method washes away the waste and old pile pipe periphery of dilution using giant
The soil body, finally realize pile pulling；Another kind is full circle swinging pile pulling method, and this method is using full circle swinging obstacle cleaning machine to waste and old pile pipe surrounding
Obstruction carries out quick circumgyration incision, and old stake is extracted or removed after pile peripheral earth is separated with old stake.Existing waste and old pile pipe
Sweep-out method needs more auxiliary equipment to carry out auxiliary construction, and construction procedure is complicated, cumbersome, has construction cost high and constructs
The defects of long in time limit.
Utility model content
For defect present in above-mentioned prior art, technical problem to be solved in the utility model is to provide one kind and applied
The button tubular type pile extractor that work cost is low, the construction period is short.
In order to solve the above-mentioned technical problem, a kind of button tubular type pile extractor provided by the utility model, it is characterised in that：Bag
Button pipe is included, and is hubbed at four pile pulling fixture blocks that can be pivoted up and down of button inside pipe wall bottom；
The button pipe is the straight tube of upper and lower ends opening, circumferential symmetrical laying of four pile pulling fixture blocks along button pipe, detains pipe
Inner wall lower is fixed with four limit card blocks, and four limit card blocks are laid in the underface of four pile pulling fixture blocks respectively；
When each pile pulling fixture block is switched to length direction perpendicular to the central axis of button pipe, under the pile pulling fixture block props up it just
The limit card block of side, and the inner of the pile pulling fixture block is located at the inner side of the limit card block.
Button tubular type pile extractor provided by the utility model, is pulled out using the cooperation of button pipe and its four pile pulling fixture blocks of bottom
Except waste and old pile pipe, pile pulling is convenient and swift, and required auxiliary equipment is few, has the characteristics of construction cost is low, the construction period is short.
Brief description of the drawings
Fig. 1 is the top view of the button tubular type pile extractor of the utility model embodiment；
Fig. 2 is the upward view of the button tubular type pile extractor of the utility model embodiment；
Fig. 3 is the button tubular type pile extractor of the utility model embodiment along the main view cut away view after the line A-A cutting in Fig. 1；
Fig. 4 is the schematic diagram that the pile pulling fixture block in the button tubular type pile extractor of the utility model embodiment is dug upwards.
Embodiment
Embodiment of the present utility model is described in further detail below in conjunction with brief description of the drawings, but the present embodiment and not had to
It is every to use similar structure of the present utility model and its similar change in limitation the utility model, the utility model all should be included in
Protection domain, the pause mark in the utility model represents the relation of sum.
As Figure 1-Figure 4, a kind of button tubular type pile extractor that the utility model embodiment is provided, it is characterised in that：Bag
Button pipe 1 is included, and is hubbed at four pile pulling fixture blocks 2 that can be pivoted up and down of button inside pipe wall bottom；
The button pipe 1 is the straight tube that upper and lower ends open, and four pile pulling fixture blocks 2 are laid along the circumferentially symmetrical of button pipe, detain pipe 1
Inner wall lower be fixed with four limit card blocks 3, four limit card blocks 3 are laid in the underface of four pile pulling fixture blocks 2 respectively；
When each pile pulling fixture block 2 is switched to length direction perpendicular to the central axis of button pipe 1, the pile pulling fixture block 2 props up it
The limit card block 3 of underface, and the inner of the pile pulling fixture block 2（Side towards button tube hub is inner side）Positioned at the limiting card
The inner side of block 3.
The utility model embodiment is used to pulling out the waste and old pile tube that is embedded in the soil body, uses Static pressure pile driver during use（Or
Vibration hammer）As power-equipment, button pipe is clamped with the fixture of Static pressure pile driver, the lower end mouth of pipe of button pipe is directed at waste and old pile tube, so
Drive button pipe at the uniform velocity to push using Static pressure pile driver afterwards, button pipe sleeve is put on waste and old pile tube, now four pile pulling fixture blocks are waste and old
Dug upwards under the block resistance of pile tube so that the diameter in the space that four pile pulling fixture blocks are enclosed is more than the external diameter of waste and old pile tube, makes
Pipe, which must be detained, smoothly to be pushed, and after four pile pulling fixture blocks that button pipe presses to its underpart are less than waste and old pile tube bottom, utilization is quiet
Pile press machine drives button pipe at the uniform velocity to rise, and now four pile pulling fixture blocks downwardly turn under the resistance of soil, until spacing by four
Fixture block blocks respectively, and now the diameter in the space that four pile pulling fixture blocks are enclosed is less than the external diameter of waste and old pile tube, with button pipe
Rise, four pile pulling fixture blocks hold the bottom of waste and old pile tube so that waste and old pile tube rises together with button pipe, so as to by waste and old stake
Pipe is extracted from the soil body.
Claims (1)
1. one kind button tubular type pile extractor, it is characterised in that：Managed including button, and be hubbed at pivot above and below four energy of button inside pipe wall bottom
The pile pulling fixture block turned；
The straight tube that the button pipe opens for upper and lower ends, the circumferential symmetrical inwall laying, detain pipe of four pile pulling fixture blocks along button pipe
