Suction type anchor pile combined structure and installation and construction method thereof
The invention discloses a suction type anchor pile combined structure and an installation and construction method thereof. The combined structure comprises a suction anchor device and a steel pipe pile; the suction anchor device at least comprises an outer cylinder, an inner cylinder, an annular top cover, water pumping holes, a water pumping and draining pipe, a water pump, a suspension hook, an inner rib plate and an outer rib plate; the inner cylinder is arranged in the center of the outer cylinder; the annular top cover, the outer cylinder and the top end of the inner cylinder are welded in a seamless mode to form a semi-closed annular cylinder; one end of the water pumping and draining pipe is connected with the two water pumping holes in a sealed mode, and the other end of the water pumping and draining pipe is connected with the water pump; the suspension hook is welded to the edge of the annular top cover; the inner rib plate is welded to the joint of the inner cylinder and the annular top cover; the outer rib plate is welded to the joint of the outer cylinder and the annular top cover; and he steel pipe pile penetrates through the inner cylinder to be subjected to static pressure pile sinking to a preset depth and is coupled with the suction anchor device through high-pressure rotary jet grouting. According to the suction type anchor pile combined structure and the installation and construction method thereof, the suction anchor device and the steel pipe pile are coupled together to reinforce an ocean pile foundation, the combined structure is convenient to transport and install and has high scouring resistance and horizontal deformation resistance, and the engineering cost is reduced.
一种吸力式锚桩组合结构及其安装施工方法，组合结构包括吸力锚装置和钢管桩，吸力锚装置至少包括外筒、内筒、环形顶盖、抽水孔、抽排水管、抽水泵、悬挂吊钩、内肋板和外肋板，内筒设置于外筒的中心，环形顶盖与外筒及内筒顶端无缝焊接形成一个半封闭式环形筒；抽排水管一端与两个抽水孔密封连接、另一端与抽水泵连接；悬挂吊钩焊接在环形顶盖边缘；内肋板焊接在内筒与环形顶盖交接处，外肋板焊接在外筒与环形顶盖交接处；钢管桩穿过内筒静压沉桩至预定的深度，通过高压旋喷灌浆与吸力锚装置耦合在一起。本发明将吸力锚装置和钢管桩耦合在一起对海洋桩基进行加固，组合结构便于运输安装且具有较强的抗冲刷性和抗水平变形能力，节约工程成本。
