通过对在地质条件复杂的高潮夕深水长大直径钻孔桩施工工艺的梳理,重点探讨了该施工工艺的工法特点、适用范围、工艺原理、工艺流程以及实施过程中的操作要点。通过合理的技术实施和流程设置,从施工准备、护筒安装、造浆钻进、钢筋制作吊装到混凝土灌注等方面,详细总结了高潮汐深水长大直径钻孔桩施工工艺,为同类地质条件的同类工程的施工建设提供了重要的参考依据。
Through the combing of construction process of high and deep water long and large diameter bored piles with complicated geologic conditions, this paper mainly discusses the characteristics of working method, applicable scope, process principle, process flow and key points in the process of implementation. Through reasonable technical implementation and process setting, the construction process of high-diameter and long-diameter-diameter bored pile at high tide and high water depth is summarized in detail from construction preparation, casing installation, cementing and drilling, steel making and hoisting to concrete pouring, The construction of similar projects provides an important reference.
