Low pile cap rapid construction method suitable for rock foundation
The invention provides a low pile cap rapid construction method suitable for a rock foundation. The low pile cap rapid construction method comprises the steps of cofferdam construction, enclosing purlin inner support construction, enclosing purlin construction, bottom sealing concrete construction, main body drilling pile construction, counter-force pile construction, dry operation environment construction, concrete pouring and the like. According to the method, underwater leveling operation is changed into waterless excavation operation, the excavation area and volume are minimum, the construction period is short, needed manpower and material resources are few, the flatness, the integrity and the waterproofness of the bottom elevation of the bearing platform can be accurately controlled conveniently, and the construction requirement can be met.
本发明提供一种适用于岩石地基的低桩承台快速化施工方法,包括：围堰施工、围檩内支撑施工、围檩施工、封底混凝土施工、主体钻孔桩施工、反力桩施工、干作业环境施工和混凝土浇筑等步骤。本发明将水下整平作业改为无水开挖作业，不仅开挖面积和方量最小，施工周期较短，所需的人工和材料资源较少，而且便于精确控制承台底标高平整度、完整度和防水性，能够满足施工要求。
