Composite pile construction method suitable for hard stratum
The invention provides a composite pile construction method suitable for a hard stratum, and relates to the technical field of building construction.The composite pile construction method suitable for the hard stratum comprises the steps that engineering muck and water are mixed and fully stirred, and muck slurry is formed; adding a rock-soil curing agent into the muck slurry, and fully and uniformly mixing to form fluid-state cured slurry; a rotary drilling rig is adopted for drilling and pore-forming operation, when the pile hole depth meeting the design requirement is reached, the drilling operation is stopped, a drilling tool of the rotary drilling rig is slowly pulled out of the pile hole, and in the drilling and pore-forming process, fluid-state solidified slurry is continuously injected into the pile hole for wall protection; and the prestressed pipe piles are inserted into the pile holes section by section through a static pressure pile machine, and the high-strength composite piles are formed. Compared with the prior art, the composite pile construction method suitable for the hard stratum can be used for construction in the hard stratum or a rock stratum, and the problem that a traditional stiff composite pile is difficult to construct in the stratum is solved.
本发明提供了一种适用于坚硬地层的复合桩施工方法，涉及建筑施工技术领域，适用于坚硬地层的复合桩施工方法包括将工程渣土和水混合并充分搅拌，形成渣土泥浆；向渣土泥浆内加入岩土固化剂并充分拌合均匀，形成流态固化泥浆；采用旋挖钻机进行钻进成孔作业，当达到设计要求的桩孔深度后，停止钻孔操作，将旋挖钻机的钻具缓慢从桩孔内抽出，在钻进成孔的过程中，向桩孔内不断注入流态固化泥浆进行护壁；采用静压桩机将预应力管桩逐节插入桩孔内，形成高强度复合桩。本发明的适用于坚硬地层的复合桩施工方法，相比于现有技术，可以在坚硬地层或岩石层施工，解决了传统劲性复合桩在上述地层难以施工的难题。
