The construction method of the recyclable steel pipe pile of above-mentioned self-advancing type comprises the following steps:
Smooth and place cleaning, measurement and positioning unwrapping wire, marks a heart position;
Off-balance bit, impactor pack into certainly entering in the steel pipe pile of connector, pile-forming machine perching;
Hoisting steel pile tube, adjust the verticality of steel pipe pile pore-forming, rig work, top injecting compressed air, off-balance bit hits sandstone around, compressed air drives bottom sandy soil to blow out from top along steel pipe pile inwall, when 60-80mm above ground level is pushed up in heavy first segment stake to stake, stops calming the anger, carry out pile extension, pile extension is complete, continues to play second section stake, until reach the required supporting degree of depth;
According to same step, according to the stake heart position marking, complete piling;
Recyclable Guan Liang is set;
Vertical cut, every downward 2 meters arrange anchor cable one, and anchor cable adopts lockset and the locking of waist rail channel-section steel, and rises and draw with drawing meter, reaches design lock value;
Linked network mask between stake;
Major project construction exceeds ground line, after pit backfill, from bottom to top, withdraws from per pass waist rail lockset, steel strand, waist rail; Unclamp again Guan Liang and the connecting bolt of being preced with beam connection, split out Guan Liang and hat beam connection; With special pipe extractor, steel pipe pile is reclaimed, taxonomic revision warehouse-in, completes the recyclable steel pipe pile support system of self-advancing type again.
The preferred version of above-mentioned construction method is: steel pipe pile section adopts rectangle left hand thread to be connected with joint, the initial end that is steel pipe pile with the steel pipe pile that certainly enters connector, off-balance bit with certainly enter connector and be connected by draw-in groove, off-balance bit tail end and impactor pass through spline joint, in the time of the injecting compressed air of top, impactor impacts off-balance bit by the reciprocating motion of piston, off-balance bit hits sandstone around, due to wobbler action, drilling diameter is greater than the diameter of steel pipe pile, steel pipe pile advances along with off-balance bit and from entering connector automatically, the air of compression constantly drives bottom sandy soil to blow out from top along steel pipe pile inwall, thereby pore-forming, piling once completes.
Described from entering the key component that connector is the recyclable steel pipe pile of self-advancing type, connect off-balance bit, impactor and steel pipe pile, thereby reach advancing voluntarily of steel pipe pile.
Described Guan Liang is recyclable Guan Liang, pushing up with every recyclable steel pipe pile stake the flange welding is connected by high-strength bolt, start every downward 2 meters from Guan Liang, one anchor cable of horizontally set, every anchor cable is arranged on steel pipe pile spacing center, anchor cable angle of incidence is 15 ° or 25 °, and anchor cable is locked on waist rail.
The recyclable steel pipe pile support system of described self-advancing type adopts steel pipe pile and anchor cable to be criss-cross arranged, and is locked the supporting and protection structure of linked network between stake by Guan Liang, waist rail.Described self-advancing type is exactly that off-balance bit and impactor pass through compressed-air actuated pressure, drives steel pipe pile to advance voluntarily.
Compared with prior art, this steel pipe pile replaces castinplace pile and the miniature steel pipe pile of cement steel composition to the utility model, no longer injects cement in pipe, is convenient to reclaim, and can repeatedly use, and has saved a large amount of steel and cement.This steel pipe pile is applicable to the deep foundation pit support of cobble, miscellaneous fill geologic structure, has solved the collapse hole problem of constructing under this geological conditions, and support rigidity is large, stability is strong, the supporting degree of depth is large.This steel pipe pile is easy to adjust the verticality of pore-forming while construction, has ensured the vertical arrangement of steel pipe pile on a mask.This steel pipe pile pore-forming, lower once complete, and speed of application improves twice.
The advantage of this construction method: pore-forming, piling once complete, solve the collapse hole phenomenon of cobble, miscellaneous fill geologic structure, the rigidity of structure is large, stability is strong, and supporting effect is good, and steel pipe pile easily recycles and reuses, efficiency of construction improves greatly, save construction cost, be easy to adjust the verticality of pore-forming while construction, ensured the vertical arrangement of steel pipe pile on a mask.
