The invention belongs to the technical field of marine anchoring foundations, and provides a novel umbrella anchor for resisting uplift load and a mounting method thereof.The novel umbrella anchor comprises a conical umbrella anchor body, the top of the umbrella anchor body is vertically downwards provided with a containing space, a connecting piece is arranged in the containing space and fixedly connected with the umbrella anchor body, and a plurality of rib plates are evenly arranged on the periphery of the connecting piece; one ends of the rib plates are fixedly connected with the connecting piece, the other ends of the rib plates are fixedly connected with the inner wall of the umbrella anchor, and clamping grooves are formed in the tops of the rib plates; the umbrella anchor is installed through pile hammer driving or self-elevating platform ballast penetration. Aiming at long-term continuous cyclic dynamic load generated by the floating platform, the device has high in-place bearing efficiency, is high in applicability to engineering geological conditions of a site, is not influenced by scouring, and is low in mounting noise and high in environmental friendliness when ballast injection is adopted, so that cost reduction and efficiency improvement of floating wind power are realized, and the construction cost is reduced. And particularly, the industrial development of tension leg type floating wind power can be obviously promoted.
本发明属于海洋锚固基础技术领域,提供了一种用于抵抗上拔荷载的新型伞锚及其安装方法,包括伞锚,伞锚为锥形,伞锚顶部竖直向下开设有容纳空间,容纳空间内设置有连接件,连接件与伞锚固定连接,连接件四周均匀设置有多个肋板,多个肋板一端与连接件固定连接,另一端与伞锚内壁固定连接,多个肋板顶部均开设有卡槽;伞锚通过桩锤打入或自升式平台压载贯入进行安装。本发明针对漂浮式平台产生的长期持续的循环动荷载,有较高的在位承载效率,对场地的工程地质条件适用性强,不受冲刷影响,在采用压载贯入时,安装噪音小,环境友好性高,因此对于漂浮式风电的降本增效,特别是张力腿式漂浮式风电的产业化发展,有显著的促进作用。
