Underwater pile foundation scouring protection device and construction method thereof
The invention discloses an underwater pile foundation scouring protection device and a construction method thereof, and belongs to the technical field of offshore wind power pile foundation scouring protection tooling. The underwater pile foundation scouring protection device comprises a plurality of sinking row assemblies arranged in an array mode; adjacent sinking row assemblies are connected through flexible cables and are laid on a seabed around an offshore wind power pile; each sinking drainage assembly comprises a framework and a sand quilt; and the sand quilts are fixed to the frameworks. Due to the fact that the sheet-shaped frameworks formed by connecting the ropes are arranged below the sand quilts, a certain supporting effect is achieved between the sheet-shaped frameworks and the sand quilts, the whole scouring protection device cannot generate large displacement due to formation of a local small scouring pit, and the situation that the exposed area of the seabed is enlarged is avoided; and the local scouring pit reaches a stable state after reaching a small depth, the area and the depth do not continue to be expanded any more, and therefore fundamental prevention of scouring of a seabed around a pile foundation is achieved from the mechanism of scouring.
本发明公开的一种水下桩基础冲刷防护装置及其施工方法，属于海上风电桩基础冲刷防护工装技术领域。包括若干阵列排布的沉排组件，相邻沉排组件之间通过柔性索相互连接，铺设在海上风电桩柱周围的海床上；沉排组件包括骨架和沙被，沙被固定在骨架上。由于沙被下面是由绳索连接而成的成片的骨架，相互之间起到一定的支撑作用，因而整个冲刷防护装置不会因为局部小的冲刷坑的形成而产生大的位移，避免了海床裸露面积扩大，由于海床裸露面积较小，局部冲刷坑在达到较小深度以后即达到稳定状态，面积和深度不再继续扩展，从而从冲刷机理上实现了对桩基础周边海床冲刷的根本扼制。
