Secant pile, sleeve for plain secant pile and construction method of sleeve
The invention relates to the technical field of pile hole concrete pouring, and discloses a secant pile, a sleeve for a plain pile of the secant pile and a construction method of the sleeve, and the construction method comprises the steps that the plain pile is prefabricated, and the position of a pile hole is measured and positioned; the drilling machine conducts hole digging in the preset position, and meanwhile slurry is poured into the pile hole; after hole digging is completed, the multiple plain piles sleeved with the sleeves are hoisted in the pile holes, the multiple plain piles are arranged at intervals, and gaps matched with the meat piles in size are formed between the adjacent plain piles; and a reinforcement cage of the meat pile is hoisted in the pile hole, and pouring of the meat pile is conducted in the gap. The process of cutting off the pile body of the plain pile is omitted, the high complexity of underground engineering and the limitation of the construction technology are avoided, the construction amount of manpower, concrete materials and construction machines is reduced, and the construction cost is reduced.
本发明涉及桩孔混凝土浇筑技术领域，公开了一种咬合桩、用于咬合桩素桩的套筒及其施工方法，其中施工方法为预制素桩，对桩孔的位置进行测量和定位；钻机在预设位置进行挖孔，同时朝桩孔中灌注泥浆；挖孔完成后，将多个套设有套筒的素桩吊装于桩孔中，多个素桩间隔设置，相邻的素桩之间具有与荤桩尺寸配合的空隙；在桩孔中吊装荤桩的钢筋笼，并在空隙中进行荤桩的浇筑。本发明使素桩减少了省去切除桩身的工序，避免了地下工程的高度复杂性和施工工艺的限制，减少了人工、混凝土材料和施工机械的施工量，降低了施工成本。
