Pile foundation engineering construction method
The invention discloses a construction method for pile foundation engineering. The construction method comprises the following steps: paying off at a pile position and embedding a pile casing; slurry preparation: the used slurry is prepared from high-quality bentonite; performing hole forming: performing rotary drilling to form holes; primary hole cleaning; after the formed hole reaches the designed elevation, the hole depth, the hole diameter, the hole wall perpendicularity and the sediment thickness are checked; manufacturing and hoisting a reinforcement cage; a lower conduit; cleaning the hole for the second time and measuring the sediment thickness; and underwater concrete pouring. The pile tip post-grouting is adopted to enhance the bearing capacity of the pile body, operation is convenient, the construction speed is high, materials are saved, economic benefits are obvious, and the construction efficiency is improved while the construction quality of the pile foundation is guaranteed.
本发明公开了一种桩基工程施工方法，包括如下步骤：桩位放线和埋设护筒；泥浆制备：使用的泥浆用优质膨润土制作而成；成孔：旋挖成孔；一次清孔；成孔检测：成孔达到设计标高后，对孔深、孔径、孔壁垂直度、沉淀厚度进行检查；钢筋笼制作与吊装；下导管；二次清孔、测定沉渣厚度；水下混凝土浇筑。本发明采用桩端后注浆以加强桩身承载力，操作方便、施工速度快、节约材料，经济效益明显，保证桩基施工质量的同时提高了施工效率。
