Positioning installation platform suitable for large-diameter single pile driving and construction method
The positioning installation platform comprises a suction anchor, a pile leg, a box-shaped deck, a hydraulic pile embracing device and a lifting frame, the pile leg penetrates through a guide hole of the box-shaped deck and is welded to the suction anchor into a whole, the hydraulic pile embracing device is fixedly arranged on the box-shaped deck, and the hydraulic pile embracing device is fixedly arranged on the box-shaped deck. The lifting frame is welded to the upper portion of the box-shaped deck, the lifting pile mechanism is arranged between the pile leg and the box girder deck, and lowering or lifting of the pile leg and the suction anchor can be achieved. Through self-floating of the box-shaped deck, the problems of marine transportation and displacement of the single-pile positioning and mounting platform are solved, and operations such as marine in-place, suction foundation penetration and deck lifting of the platform are completed under the assistance of a single tug; through the self-floating and intelligent mechanical design of each part structure, a self-installation process without floating crane and barge transportation in offshore installation is realized, the installation operation is simple, the operation period is short, the device can be repeatedly used, the requirement on auxiliary installation machines and tools is low, and the comprehensive cost is relatively low.
本发明公开了一种适用于大直径单桩打入的定位安装平台及施工方法，包括吸力锚、桩腿、箱形甲板、液压抱桩装置和吊装架，桩腿穿过箱形甲板的导向孔并与吸力锚焊接为一体，箱形甲板上固定设置有液压抱桩装置，吊装架焊接安装于箱形甲板上部，桩腿与箱梁甲板之间设有升降桩机构，可实现对桩腿和吸力锚的下放或提升。本发明通过箱形甲板自浮，解决了单桩定位安装平台海上运输和移位问题，实现平台在单条拖轮辅助下完成海上就位、吸力基础贯入、甲板提升等操作；通过各部结构的自浮和智能化机械设计，实现海上安装无需浮吊和驳船运输的自安装工艺，安装作业简易，作业周期短，可重复使用，对辅助安装机具的要求低，综合成本较低。
