Grouting-free piston type suction foundation and method
The invention belongs to the technical field of foundation construction in ocean engineering, and provides a grouting-free piston type suction foundation and a method. The grouting-free piston type suction foundation comprises a suction foundation body and a piston partition plate. The piston partition plate is clamped in the suction foundation and can move up and down along the inner side wall of the suction foundation; the piston partition plate comprises a partition plate, a rotary one-way plate and a hollow hole; the hollowed-out holes are evenly formed in the partition plate, and rotary one-way plates are arranged on the hollowed-out holes. The rotary one-way plate can completely cover the hollowed-out hole and is larger than the hollowed-out hole in size, one end of the rotary one-way plate is a fixed end, the other end of the rotary one-way plate is a movable end and can be opened in the direction from the fixed end to the top of the suction foundation, and soil plug formation is effectively restrained in the process that the suction foundation penetrates into a soil body; and grouting treatment is omitted after foundation penetration is completed, so that the stability of foundation penetration into the seabed is improved.
本发明属于海洋工程中的基础施工技术领域，提供了一种免注浆活塞式吸力基础及方法。其中，免注浆活塞式吸力基础包括吸力基础和活塞隔板；所述活塞隔板卡设在吸力基础内部，且可沿吸力基础内侧壁上下移动；所述活塞隔板包括隔板、转动式单向板和镂洞；所述镂洞均匀设置在隔板上，所述镂洞上设置转动式单向板；所述转动式单向板可完全覆盖镂洞且尺寸大于镂洞，所述转动式单向板的一端为固定端，另一端为活动端且可沿固定端向吸力基础顶部方向打开，其使得吸力基础贯入土体的过程中有效抑制土塞的形成，并且基础贯入完成后免除注浆处理，从而提高基础贯入海床的稳定性。
