Further arrange and be:
Described pulling force mobile jib is hollow steel tube.
Described pressure-control valve is controlled liquid or gas turnover pulling force mobile jib, be preferably and be threaded between pulling force mobile jib and pressure-control valve, with convenient, accurately control entering of gas or liquid.
Described liquid hole is provided with 4, and two of every sides are centrosymmetric and are arranged on the pulling force mobile jib.
Described anchoring liquid capsule is preferably the elastic polyethylene leather bag, and to be filled with easily gas or liquid, and Exhaust Gas or liquid carry out recycling.
Anchoring liquid capsule, when the topping up state, provides the anchoring pulling force by the extruding surrounding soil, and anchoring liquid capsule, after internal liquid is emitted, retracts to its nature.
Described friction particles preferably is set to the taper shape of bottom surface diameter 0.5cm, high 1cm, when can effectively for anchored end, provide pulling force, completes easily again recycling.
Using method of the present utility model is as follows:
(1) boring: in the design attitude boring of foundation ditch side, the diameter of boring is greater than the diameter of pulling force mobile jib, and the length of boring is greater than the length of pulling force mobile jib;
(2) apply negative pressure: by pressure-control valve, to the tension anchor rod internal air exhausting, in the inner negative pressure that produces of tension anchor rod, make anchoring liquid capsule evenly be wrapped in pulling force mobile jib tail end;
(3) place anchor pole: accurately be placed in hole forward to the tension anchor rod afterbody applied after negative pressure;
(4) topping up work: be filled with the liquid of setting volume by pressure-control valve to the anchoring liquid capsule internal high pressure of tension anchor rod, make tension anchor rod reach duty;
(5) discharge liquid: after pattern foundation pit supporting structure, discharge the anchoring liquid capsule internal liquid of tension anchor rod by pressure-control valve, make anchoring liquid capsule retract to reset condition;
(6) apply negative pressure: repeating step (2) breaks away from anchoring liquid capsule and surrounding soil fully and evenly is wrapped in pulling force mobile jib tail end;
(7) recycle: reclaim tension anchor rod from the design hole, in order to using next time, and fill up the design hole with the coarse sand backfill.
Useful result of the present utility model is:
The slurry material and the anchor pole that have overcome traditional tension anchor rod are forever stayed in the soil body, the defects such as construction of follow-up building around impact, bleed to reclaim by topping up work and tapping and realize that anchor recovering recycles, save material and environment is not produced and pollutes again, easy to operate.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
