Offshore wind power pile foundation anti-scouring device and construction method thereof
The invention relates to an offshore wind power pile foundation anti-scouring device and a construction method thereof. The device comprises a support table surrounding a pile foundation, a protective layer, an embedded structure, a constraint circular ring and a flip bucket. The protective layer is made of a quick-setting cement blanket; the bottom of the support table makes contact with the earth surface, the constraint ring is located above the support table, and the flip bucket is located above the constraint ring. A distance is reserved between the embedded structure and the bracket table; the protection layer and the support table are fixedly connected to form a reverse umbrella-shaped structure, and the inner edge of the protection layer and the outer edge of the flow deflecting table are fixedly connected to form a flow deflecting structure. The quick-setting cement blanket has the characteristics of high mechanical property and anti-permeability strength, convenient laying and forming and quick hardening, a protective layer of a specific structure is built, impact water flow is ejected back along the surface of the protective layer, the situation that the water flow scours foundation soil on the periphery of a pile foundation is avoided, the adverse effect of the water flow on the stability of a pile body is reduced, and the service life of the pile body is prolonged. And the application range covers the intertidal zone muddy seabed.
本发明涉及一种海上风电桩基防冲刷装置及其施工方法。该装置包括环绕桩基的支架台、防护层、内嵌结构、约束圆环以及挑流台；防护层材质为速凝型水泥毯；支架台的底部与地表相接触，约束圆环位于支架台上方，挑流台位于约束圆环上方；内嵌结构与支架台之间留有距离；防护层与支架台固定连接以形成反伞状结构，防护层内缘与挑流台外边缘固定连接并形成挑流结构。本发明利用速凝型水泥毯具有较高力学性能和抗渗强度、及铺设成型便捷和快速硬化的特性，搭建特定结构的防护层使冲击水流顺沿防护层表面挑射回去，避免水流冲刷桩基周边地基土体，降低水流对桩身稳定的不利影响，适用范围涵盖潮间带淤泥质海床。
