Description
Technical field
The utility model relates to a kind of technique device of novel casing, in particular a kind of rig casing device, is applicable to there is emptying aperture on long screw auger drilling deposited pile stake top operating mode to ground.
Background technology
In pile foundation, long screw auger drilling deposited pile technique does not limit by groundwater table due to the Superfluid state concrete of its pumping, and friction factor is low, aggregate good dispersion, not easily produces the feature of segregation, in addition its pore-forming one machine once complete, easy and simple to handle; Low noise, friction, construction cost is relative moderate compared with other construction methods.Within 2005, be classified as one of ten large disseminate technologies by the Ministry of Construction.Be developed so far, long screw auger drilling deposited pile technique is widely applied at pile foundation engineering, and so along with construction demand constantly changes, many areas use long auger technique to need to carry out emptying aperture construction (non-natural ground, stake top).And this construction method exists following drawback, filling concrete will certainly be wasted concrete to ground; And not by filling concrete to ground, then stake top is to the easy collapse hole of above ground portion, affects pile quality.
Summary of the invention
A kind of casing device is the object of the present invention is to provide to carry out retaining wall to the emptying aperture part soil body in long auger process, thus reduce filling concrete amount or avoid collapse hole or the residual soil body to enter pile concrete, be lowered into quality of pile, can improve simultaneously long auger in and verticality and construction safety degree.
The object of the invention is by realize with lower device, long-spiral drilling machine casing device, comprise pulley, slideway, axis tile, fixed head, gripper shoe, otic placode, casing connection centralizer, it is characterized in that: the pulley that long-spiral drilling machine tower bar is arranged is connected the pulley that centralizer is arranged and forms assembly pulley with casing, control casing connection centralizer and move up and down; Gripper shoe is fixed on tower bar by axis tile, fixed head, dowel; Casing is connected centralizer and is connected by otic placode with gripper shoe, and casing is fixed on casing by casing steady pin and connects in centralizer.
As preferred scheme, long-spiral drilling machine tower bar arranges inverted trapezoidal crossbeam, the distribution of two ends, crossbeam left and right arranges 1 pulley.
As preferred scheme, the thick 300 ~ 400mm of inverted trapezoidal crossbeam, top margin long 1000 ~ 1500mm, bottom side length 2000 ~ 3000mm, high 500 ~ 700mm, diameter of pulley 200 ~ 300mm.
As preferred scheme, on long-spiral drilling machine tower bar, left and right arranges twice slideway, and casing is connected centralizer and is connected with tower bar slideway by both sides axis tile.
As preferred scheme, casing connects centralizer to be fixed by casing steady pin and casing.
As preferred scheme, above casing connection centralizer, corner arranges 4 otic placodes, arranges 2 pulleys, with moving up and down of tower bar upper cross-beam end pulley co-controlling casing centralizer in the middle of the casing centralizer left and right sides.
As preferred scheme, casing connects centralizer and gripper shoe and is connected the rear side otic placode of centralizer by casing and junction plate is fixed.
As preferred scheme, junction plate both sides connect casing and connect on rear side of centralizer and gripper shoe bottom otic placode, and be that rectangle is shaft-like in the middle part of junction plate, length is 900 ~ 1100mm.
As preferred scheme, gripper shoe is fixed on tower bar slideway by axis tile, fixed head, dowel.
Long-spiral drilling machine, starts boring, increases with drilling depth, and casing device controls casing and declines, until specified altitude assignment, makes a casing end face segment distance above ground level, plays retaining wall effect.
The present invention can carry out retaining wall to the emptying aperture part soil body in long auger boring procedure, thus reduce filling concrete amount or avoid collapse hole or the residual soil body to enter pile concrete, be lowered into quality of pile, can improve simultaneously long auger in and verticality and construction safety degree.

Accompanying drawing number title: 1. tower bar pulley, 2. axis tile, 3. dowel, 4. fixed head, 5. gripper shoe, 6. otic placode, 7. junction plate, 8. casing connect centralizer, 9. casing steady pin, 10. casing and connect centralizer pulley (please marking in the accompanying drawings), 11. casings, 12. tower bars, 13. slideways.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
It comprises tower bar pulley 1 and connects casing connection centralizer 8 as shown in the figure, control its lifting, gripper shoe 5 by axis tile 2, dowel 3, fixed head 4, be connected on long-spiral drilling machine tower bar, gripper shoe 5 is connected by 2 groups of otic placodes 6 with casing centering connector 8, and casing 11 is fixed on casing by casing steady pin 9 and connects in centralizer.
Long-spiral drilling machine boring starts, increase with drilling depth, to be connected centering connector pulley 10 with casing by tower bar pulley 1 and to control casing centering connector 8 and casing 11 declines, casing is fixed on casing connection centralizer 8 by casing steady pin 9, until designated depth, casing plays retaining wall effect.When boring completes, concrete perfusion completes, and takes off casing steady pin 9, removes rig, uses soil sampler, takes the residual soil body in emptying aperture part casing away.Anti-plug reinforcing cage afterwards, after reinforcing cage has been transferred, is fixed on casing by casing 11 by casing steady pin 9 and connects on centralizer 8, be connected centralizer pulley 10 by tower bar pulley 1 with casing, promote casing 11, to ground, complete whole work progress.
