Novel offshore wind power foundation suitable for shallow covering layer and construction method thereof
The invention discloses a novel offshore wind power foundation suitable for a shallow covering layer and a construction method thereof. The novel offshore wind power foundation comprises a single pile, wherein a gravity disc is fixedly mounted on the single pile; a plurality of spiral piles are uniformly distributed and fixedly mounted at the periphery of the gravity disc; and the adjacent spiral piles are fixedly connected to form an integral structure. The anti-pulling bearing capacity and the horizontal bearing capacity of the foundation are improved through the spiral piles and the gravity disc, the horizontal displacement of a pile body is reduced, and the bending moment of the pile body is reduced; the spiral piles, the gravity disc and the single pile are spliced and rigidly connected, so that various mechanical indexes of the whole foundation are improved; and therefore, the engineering needs of safe and stable operation of offshore wind power are met under the condition that the single pile does not need to be embedded into bed rock.
本发明公开了一种适用于浅覆盖层的海上风电新型基础及其施工方法，它包括单桩，所述单桩上固定安装有重力盘，所述重力盘的外围均布固定安装有多根螺旋桩；相邻的螺旋桩之间固定相连并构成整体结构。通过螺旋桩与重力盘提高基础的抗拔承载能力与水平承载能力，降低桩身水平位移，减小桩身弯矩；通过将螺旋桩、重力盘、单桩拼接，刚性连接，提高整个基础的各项力学指标；从而实现在单桩无需嵌入基岩情况下，满足海上风电安全稳定运行的工程需要。
