Underwater bare rock area steel pipe pile anchoring construction method
The invention discloses an underwater bare rock area steel pipe pile anchoring construction method which comprises the following steps that firstly, hole guiding is conducted on a bare rock face through an underwater buoyancy tank percussion drill, then after steel pipe piles are put into holes through a crane and temporarily stabilized, the steel pipe piles are connected into a whole through welding and parallel connection, and a platform of a geological drilling rig is erected at the tops of the steel pipe piles; a geological core-pulling machine is installed on a pile top platform, then a guide pipe is used for extending into a riverbed rock surface in the steel pipe pile, and the steel pipe pile is drilled into the position 3 m below a rock stratum through a geological drill; after core pulling is completed, a seamless concrete core steel pipe rod with the length of 4 m is inserted into the hole bottom through a guide pipe, and then the guide pipe is pulled out; a guide pipe for pile foundation pouring is installed, and C30 underwater concrete with the height of 3 m is poured into the steel pipe pile according to the underwater pile foundation pouring technology; after the concrete in the steel pipe piles is equal in strength, the steel pipe piles and the rock stratum form an anchoring structure through the concrete and the seamless steel pipes, anchoring steel pipe pile construction is completed, the geological drilling rig construction platform is dismantled, and the trestle superstructure continues to be erected.
本发明公开了一种水下裸岩区钢管桩锚固施工方法，包括以下步骤：先通过水上浮箱冲击钻在裸露岩面上进行引孔，然后通过吊机将钢管桩下放入孔内并临时稳固后，焊接平联将钢管桩连成整体，并在钢管桩顶部搭设地质钻机的平台；在桩顶平台上安装地质抽芯机，然后在钢管桩内用导管探入河床岩面，并通过地质钻钻入岩层以下3m；抽芯完成后，通过导管插入4m长无缝砼芯钢管棒至孔底，然后拔除导管；安装桩基灌注用导管，并按照水下桩基灌注工艺，在钢管桩内浇筑3m高C30水下混凝土；钢管桩内部混凝土等强后，钢管桩通过混凝土和无缝钢管与岩层形成锚固结构，完成锚固钢管桩施工，拆除地质钻机施工平台，继续搭设栈桥上部结构。
