Pile slipping prevention control device for ocean large-diameter pipe pile installation
The invention discloses a pile slipping prevention control device for ocean large-diameter pipe pile installation. The pile slipping prevention control device comprises a limiting structure and a flow limiting device; the flow limiting device comprises an inner steel ring; the inner steel ring is provided with a center water permeable hole; the hole diameter of the center water permeable hole is designed according to the maximum penetration speed allowed by a pipe pile; a flow limiting plate is arranged at the bottom of the inner steel ring; an outer steel ring is arranged on the outer edge of the flow limiting plate; the outer diameter D1 of the outer steel ring is smaller than the inner diameter D2 of the pipe pile; the flow limiting plate is provided with reinforcing ribs; the limiting structure comprises a first limiting ring and a second limiting ring, wherein the first limiting ring and the second limiting ring are welded to the inner wall of the pipe pile and located at the lower end of the flow limiting plate, and the second limiting ring is located at the upper end of the outer steel ring; and N triangular ribs evenly distributed in the circumferential direction are welded between the upper end of the first limiting ring and the inner wall of the pipe pile, and N triangular ribs evenly distributed in the circumferential direction are welded between the second limiting ring and the inner wall of the pipe pile. According to the pile slipping prevention control device, the pile slipping problem in ocean pipe pile installation is solved by adjusting the water permeable amount, the structural design is simple, manufacturing is fast, penetration at the safe speed is achieved, the piling cost is saved, safety and reliability are achieved, and great economical efficiency is achieved.
本发明公开了一种用于海洋大直径管桩安装中防溜桩控制装置，包括限位结构和限流装置，限流装置包括内钢环，内钢环设有中心透水孔，其孔径根据管桩允许的最大贯入速度设计内钢环的底部设有限流板，限流板的外缘设有外钢环，外钢环的外径D1小于管桩的内径D2，限流板上设有加强肋；限位结构包括分别焊接在管桩内壁上、且位于限流板下端的第一限位环和位于外钢环上端的第二限位环，第一限位环的上端与管桩的内壁之间、第二限位环与管桩的内壁之间均焊接有N个周向均布的三角肋。本发明通过调节透水量大小来解决海洋管桩安装中的溜桩问题，结构设计简单，制作快捷，实现在安全速度下贯入，节省打桩成本，安全可靠，具有极大的经济性。
