Pile-forming construction method for rotary excavating and hard cutting of secant piles in deep and thick rock-filled sludge stratum
The invention relates to the technical field of secant piles, and discloses a pile-forming construction method for rotary excavating and hard cutting of secant piles in a deep and thick rock-filled sludge stratum. The pile-forming construction method comprises the following construction steps that (1), a construction site is leveled, and a pile position is determined; (2), a casing pipe is rotated by a pipe twisting machine and pressed down, a rock-filled layer is crushed by a punch hammer, and soil is taken to form a plain pile hole; (3), slag in the plain pile hole is removed and concrete is poured; (4), excavating down is carried out by a rotary drilling rig, a pre-excavating hole is formed, the rotary drilling rig drives the casing pipe to drill into a soil layer, a cone drill cylinder cuts a rock filling layer, and soil is taken to form a reinforced pile hole; and (5), after slag removal treatment is carried out on the reinforced pile hole, a reinforcement cage is put down, concrete is poured, the secant piles are formed, the casing pipe is arranged through the pipe twisting machine, the impact hammer is adopted for crushing when large rocks are filled, a impact grab bucket is adopted for taking soil, the hole forming speed is high, the casing pipe is arranged through a rotary drilling driver, the rotary drilling rig is matched with a roller bit for drilling and hole forming, the perpendicularity error is small, the drilling speed is increased, and the problem that in the prior art, the construction speed of the secant piles in the rockfill sludge stratum is low is solved.
本发明涉及咬合桩的技术领域，公开了深厚填石淤泥地层旋挖硬切割咬合桩的成桩施工方法，包括以下施工步骤：(1)、平整处理施工场地，确定桩位(2)、搓管机转动套管下压，冲锤破碎填石层，取土形成素桩孔(3)、素桩孔清渣及灌注混凝土(4)、旋挖钻机下挖，形成预挖孔，旋挖钻机驱动套管钻入土层，牙轮钻筒切割填石层，取土形成荤桩孔(5)、荤桩孔清渣处理后下放钢筋笼，灌注混凝土，形成咬合桩；利用搓管机下套管，遇大块填石采用冲锤破碎，冲抓斗取土，成孔速度快，利用旋挖驱动器下套管，采用旋挖钻机搭配牙轮钻头钻进成孔，垂直度误差小，提高钻进速度，解决现有技术中，填石淤泥地层咬合桩施工速度慢的问题。
