Further arrange and be:
Described pulling force mobile jib is hollow steel tube.
Be preferably between described pressure-control valve control liquid or the gas turnover pulling force mobile jib, pulling force mobile jib and pressure-control valve and be threaded, 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 being filled with easily gas or liquid, and Exhaust Gas or liquid carry out recycling.
Anchoring liquid capsule provides the anchoring pulling force by the extruding surrounding soil when the topping up state, anchoring liquid capsule retracts to its nature after internal liquid is emitted.
Described friction particles preferably is set to the taper shape of bottom surface diameter 0.5cm, high 1cm, when can effectively provide pulling force for anchored end, finishes easily again recycling.
Another aspect of the present invention provides a kind of using method of recyclable liquid-filled tension anchor rod, it is characterized in that, comprises the steps:
(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: 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 by pressure-control valve;
(3) place anchor pole: accurately be placed in the hole forward to the tension anchor rod afterbody that applies after the 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 is complete, 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: from the design hole, reclaim tension anchor rod, use in order to next, and fill up the design hole with the coarse sand backfill.
Useful result of the present invention is:
The slurry material and the anchor pole that have overcome traditional tension anchor rod are forever stayed in the soil body, the defectives such as construction of follow-up building around the impact, bleed by topping up work and tapping and reclaim to realize that anchor recovering is recycling, namely save material and environment is not produced again and pollute, easy to operate.
The invention will be further described below in conjunction with the drawings and specific embodiments.
