Occlusive pile construction method combining high-strength deep solidified stirring pile and rotary excavating cast-in-place pile
The invention relates to the technical field of secant piles, and discloses a secant pile construction method combining a high-strength deep curing stirring pile and a rotary excavating cast-in-place pile, which comprises the following construction steps: 1) stirring and mixing a curing agent and a water body to form curing slurry, the curing agent is formed by stirring and mixing sulphoaluminate cement, Portland cement, superfine slag powder, desulfurized gypsum, fine aggregate, silica fume and a water reducing agent; (2) a grouting pipe is arranged on the cage type stirring head, in the stirring and drilling process of the cage type stirring head in the soil body, a slurry outlet pipe sprays solidified slurry into the soil body, the solidified slurry and the soil body are stirred and mixed, and a stirring pile is formed; (3) the step (2) is repeated, and a plurality of stirring piles are formed in the soil body; (4) a rotary excavating pile hole is formed through drilling of the cutting tooth drilling barrel; a reinforcement cage is put into the rotary excavating pile hole, concrete is poured, and a cast-in-place pile is formed; and (5) the step (4) is repeated, a plurality of cast-in-place piles are formed, the cast-in-place piles are meshed with the two adjacent stirring piles, and the multiple stirring piles and the multiple cast-in-place piles form secant piles.
本发明涉及咬合桩的技术领域，公开了高强深层固化搅拌桩和旋挖灌注桩结合的咬合桩施工方法，包括以下施工步骤：1)、将固化剂与水体搅拌混合形成固化浆液，固化剂由硫铝酸盐水泥、硅酸盐水泥、矿渣微粉、脱硫石膏、细骨料、微硅粉以及减水剂搅拌混合形成；2)、笼式搅拌头上设有注浆管，笼式搅拌头在土体中搅拌钻进的过程中，出浆管往土体中喷射固化浆液，固化浆液与土体搅拌混合，形成搅拌桩；3)、重复步骤2)，在土体中形成多个搅拌桩；4)、利用截齿钻筒钻进形成旋挖桩孔；在旋挖桩孔中下入钢筋笼、灌注混凝土，形成灌注桩；5)、重复步骤4)，形成多个灌注桩，灌注桩与相邻的两个搅拌桩相互咬合，多个搅拌桩与多个灌注桩形成咬合桩。
