Micro-disturbance formed steel pipe cement composite pile and pile forming method thereof
The invention provides a micro-disturbance formed steel pipe cement composite pile and a pile forming method thereof, and the method comprises the following steps: determining the position of a pile foundation, then drilling, and forming a vertical slurry pre-guide hole in a soil layer; mud replacement with cement is completed in the mud pre-leading hole; the steel pipe is hoisted and lowered into the pre-guiding hole; the lowered steel pipe is fixed and compacted, and the cement is solidified into a pile; surface soil is removed, pile top cement is chiseled away to the designed elevation, and the hanging bracket is dismantled for use. According to the micro-disturbance formed steel pipe cement composite pile and the pile forming method thereof, the construction procedure is simple, the needed construction equipment and personnel investment is small, then it is guaranteed that the pile forming process is economical and efficient, meanwhile, the disturbance influence of the construction process on the surrounding environment is very low, and the micro-disturbance formed steel pipe cement composite pile is particularly suitable for a supporting main body with the strict vibration control requirement.
本发明提供了一种微扰动成型钢管水泥复合桩及其成桩方法，步骤为：确定好桩基位置后钻孔，在土层形成竖直泥浆预引孔；在泥浆预引孔内完成水泥置换泥浆；将钢管起吊下放至预引孔内；将下放的钢管固定压实，待水泥凝固成桩；清除表土，凿除桩顶水泥至设计标高，并拆除吊架备用。本发明所述的一种微扰动成型钢管水泥复合桩及其成桩方法，施工工序简单，所需施工设备及人员投入较少，进而保证成桩过程的经济高效，同时，施工过程对周边环境的扰动影响非常低，特别适用于有较为严格震动控制要求的支护主体。
