Long spiral guide hole and pressing immersed tube combined noise reduction construction method for immersed tube cast-in-place pile
The invention relates to the technical field of cast-in-place pile construction, and discloses an immersed tube cast-in-place pile long spiral guide hole and pressing immersed tube combined noise reduction construction method which comprises the following construction steps that (1) a long spiral drilling machine is driven to a construction site; (2) the long spiral drilling machine drives a spiral drilling rod to cut through a power head, and a guide hole is formed; (3) the sleeve is downwards pressed into the guide hole through the static pressure pipe sinking pile press, and a pile hole is formed in the sleeve; (4) after a reinforcement cage is lowered into the pile hole, the reinforcement cage and the concrete form a pile in the pile hole; (5) a hydraulic oil cylinder in the static pressure pipe sinking pile press clamps and pulls out the casing pipe through a pile clamping box; a long spiral drilling machine is used for guiding holes, so that the problem that the pipe-sinking cast-in-place pile is difficult to sink when encountering a dense stratum or a hard interlayer sleeve is solved; during pipe sinking, a static pressure pipe sinking pile press is adopted for construction, no noise is generated during hole guiding and pipe sinking, the problem that noise disturbs residents in pipe sinking cast-in-place pile construction is solved, and the sleeve pressing and pulling-out construction efficiency is effectively improved.
本发明涉及灌注桩施工的技术领域，公开了沉管灌注桩长螺旋引孔与压沉管组合降噪施工方法，包括以下施工步骤：1)、将长螺旋钻机开至施工场地；2)、长螺旋钻机通过动力头驱动螺旋钻杆切削，形成引孔；3)、利用静压沉管压桩机将套管下压在引孔中，套管内形成桩孔；4)、往桩孔内下放钢筋笼后，钢筋笼与混凝土在桩孔中形成桩；5)、静压沉管压桩机中的液压油缸通过夹桩箱将套管夹紧拔出；通过长螺旋钻机引孔，避免了沉管灌注桩遇密实地层或硬质夹层套管难以下沉问题；沉管时采用静压沉管压桩机施工，引孔、沉管时均无噪声，解决了沉管灌注桩施工中存在噪声扰民的问题，有效提升了套管下压和拔出施工效率。
