Novel marine suction pile and construction method thereof
The invention provides a novel marine suction pile and a construction method thereof. The novel marine suction pile is characterized in that the novel marine suction pile comprises a hollow pile body and an inner adding cover arranged on the inner side of the pile body, a pile top cover through hole used for water drainage, air exhaust and water pumping is formed in a pile top cover of the pile body, and the inner adding cover is provided with an inner adding cover through hole used for water drainage and air exhaust. The novel marine suction pile is also known as a novel marine suction barrel, the internal design of the suction pile is optimized, the problem that the bearing capacity of a pile foundation is insufficient due to the fact that a drainage/exhaust hole or a water pumping hole of the pile top cover loses efficacy in the suction pile operation period is solved, and then the risks of accidental sinking, large-amplitude inclination or continuous sinking of the suction pile is avoided; and meanwhile, grouting is not needed during installation operation of the novel marine suction pile, and the construction period and marine operation expenditure are greatly saved.
本发明提供一种海洋新型吸力桩及其施工方法，所述海洋新型吸力桩，其特征在于，包括中空的桩体和设置在桩体内侧的内增盖，所述桩体的桩顶盖上开设有用于排水、排气和抽水的桩顶盖通孔，所述内增盖上开设有用于排水、排气的内增盖通孔。该海洋新型吸力桩也称海洋新型吸力桶，该海洋新型吸力桩通过优化吸力桩内部设计，消除了吸力桩作业期间因桩顶盖排水/排气孔或抽水孔封锁失效的情况下导致桩基础承载力不足，进而避免吸力桩意外下沉，大幅度倾斜或持续下沉的风险；同时本海洋新型吸力桩安装作业时无需灌浆，大量节省工期和海上作业经费。
