PLC construction method pile cofferdam construction method
The invention provides a pile cofferdam construction method based on a PLC construction method. The pile cofferdam construction method comprises the steps of lofting, pile planting, pouring and supporting. After lofting and groove milling, multiple groups of PLC construction method piles are matched with an arc-shaped tray, are inserted and driven to a preset depth and then are closed, grouting and water stopping are performed in multiple times after closing, a gap between a rock surface and bottom sealing concrete is closed, then a lower system is assembled through a cofferdam, an inner support is assembled in multiple stages, and four supporting systems are lowered in multiple stages; when counter-acting force generated by the cofferdam acts on the arc-shaped tray, force is transferred to the inner support and the system is balanced, supporting is completed, compared with an existing construction method, four supporting systems are arranged, the better supporting effect can be achieved, the cofferdam can adapt to more diversified construction environments, and the construction efficiency is improved. And the constructors can increase or decrease the number of the supporting systems according to own requirements, so that the supporting is more flexible.
本发明提供一种PLC工法桩围堰施工方法，包括：放样步骤、栽桩步骤、浇筑步骤和支撑步骤。本发明在放样铣槽后，将多组PLC工法桩与弧形托盘吻合，插打至预设深度后进行合龙，合龙后分次注浆止水，封闭岩面与封底混凝土之间的空隙，而后通过围堰拼装下方系统，分阶段拼装内支撑，并分阶段下放四道支撑系统，当围堰产生的反作用力作用到弧形托盘上，传力给内支撑，系统建立平衡后，支撑完毕，相较于现有的施工方法，设置四道支撑系统，能够实现更好的支撑效果，能够适应更多样化的施工环境，且施工人员可根据自身需求增加或减少支撑系统的数量，支撑更加灵活。
