Offshore pile foundation anti-scouring device and pile foundation scouring pit construction method
The invention particularly discloses an offshore pile foundation anti-scouring device and a pile foundation scouring pit construction method. The anti-scouring device for the offshore pile foundation comprises a barrel-shaped foundation, a pumping and discharging opening and a stacking layer, the barrel-shaped foundation is provided with a cavity with a downward opening, at least part of the section of the barrel-shaped foundation is embedded in a soil layer of the seabed, the barrel-shaped foundation is arranged in the circumferential direction of the pile foundation, the pumping and discharging opening is formed in the barrel-shaped foundation and communicates with the cavity, and the stacking layer is arranged on the barrel-shaped foundation. The cavity is connected with negative pressure pumping and discharging equipment through the pumping and discharging opening so that materials in the cavity can be pumped and discharged, negative pressure can be formed in the cavity, and the materials are stacked on the barrel-shaped foundation and above the soil layer between the barrel-shaped foundation and the pile foundation to form a material stacking layer. The anti-scouring device effectively solves the scouring problem of the pile foundation in the service period, and safe and stable operation of a unit in the expected life cycle is achieved.
本发明具体公开一种海上桩基防冲刷装置及桩基基础冲坑施工方法。所述海上桩基防冲刷装置，包括筒型基础、抽排口和堆料层，筒型基础具有开口向下的腔室，筒型基础的至少部分区段嵌设在海底的土层中，筒型基础设在桩基的周向，抽排口设在筒型基础上并与腔室连通，腔室通过抽排口与负压抽排设备连接，以抽排腔室内的物质并使腔室内形成负压，物料堆叠于筒型基础上、以及筒型基础与桩基之间的土层上方以形成堆料层。本发明公开的防冲刷装置有效地解决桩基基础在服役期的冲刷问题，实现机组预期生命周期内的安全稳定运行。
