Abstract
The invention discloses a kind of cast-in-situ bored pile pile making method, replaces existing steel reinforcement cage by steel pipe, commerical ready-mixed concrete is replaced by rubble and cement mortar.First, punched by rig, empty after reaching designed elevation, then transfer hollow steel pipe (steel tube surface has made aperture), steel pipe is laid and be outwardly and inwardly covered with graded broken stone and while transferring Grouting Pipe in steel duct in steel pipe after terminating, start high-pressure injected water mud when rubble is covered with whole stake, the i.e. pile after slurry is filled.It is possible that steel reinforcement cage is separated and deviateed in avoiding work progress, and the phenomenon of concrete disintegration.In addition, the inventive method is simple, sound construction, construction cost be not high, it is adapted to promote the use of in correlative technology field.
Description
Technical field：Patent of the present invention is related to building engineering field, more particularly to cast-in-situ bored pile pile making method.
Technical background：
Existing reinforced concrete bored pile, such pile foundation pile by way of transferring steel reinforcement cage and then casting concrete.There are shortcomings in reinforced concrete bored pile, steel reinforcement cage first belongs to colligation splicing, it is possible that steel reinforcement cage separation and the problem for deviateing in work progress.If pile foundation is deeper, vibrate in addition uneven, easily segregation phenomenon is produced in concreting process, have a strong impact on pile foundation quality.
The content of the invention：
The purpose of patent of the present invention be for the deficiencies in the prior art in place of, there is provided a kind of cast-in-situ bored pile pile making method.
Patent of the present invention uses steel pipe instead as the framing structure of foundation pile, reduces the problem that steel structure framework is separated with aggregate and deviateed, effectively improves the globality of foundation pile internal structure.
Patent of the present invention is during concreting, it will usually the phenomenon of concrete disintegration occur, and our invention is used, then Reperfu- sion cement mortar with the construction technology vibrated, and effectively solves this problem.
The inside of patent stake of the present invention is no longer steel reinforcement cage, but high tensile steel tube, and steel pipe side for convenience slip casting and beaten aperture in advance.
Description of the drawings：
Fig. 1：1, steel pipe；2, cement mortar and macadam-aggregate mix；3, Grouting Pipe.
Fig. 2：The top view of Fig. 1
Specific embodiment：
1：Rig pore-forming is first passed through, borehole cleaning after designed elevation is reached.
2：Make the hollow steel pipe of aperture in decentralization side.
3：Outwardly and inwardly be covered with graded broken stone in steel pipe, while Grouting Pipe is transferred in the middle of steel duct, treat that rubble is covered with whole stake.
4：Start high-pressure injected water mud, the i.e. pile after slurry is filled.
