Water milling drilling dig-hole pile construction method for pile foundation
The invention discloses a water milling drilling dig-hole pile construction method for a pile foundation. The water milling drilling dig-hole pile construction method specifically comprises the following steps that S1, preparation work before construction is conducted, specifically, a site and surrounding areas are investigated, geological, hydrological and meteorological data provided by design are rechecked, whether the pile position, the elevation and the axis position of a construction drawing conform to a design construction drawing or not is rechecked, and a construction site is leveled; S2, surveying, setting out and pile position determination are conducted, specifically, the construction site is surveyed according to a design drawing, and the center of the hole pile position is determined; S3, first section excavation is conducted, and the center of a hole pile is excavated; and S4, a wellbay and a retaining wall are constructed. The hole wall is well protected in the construction process, the pile hole size is conveniently controlled, the problem that the hole diameter is too wide and too large in a traditional technology is solved, and the concrete pouring volume is conveniently and effectively controlled.
本发明公开了一种用于桩基的水磨钻挖孔桩施工方法，该施工方法具体包括以下步骤：S1：施工前准备工作，包括调查现场及周边地区，对设计提供的地质、水文、气象资料进行复核，复核施工图纸的桩位、标高及轴线位置与设计施工图是否相符，并对施工场地进行场地平整；S2：测量放线、定桩位，根据设计图纸对施工场地进行测量，确定孔桩桩位中心；S3：首节开挖，对孔桩中心进行开挖；S4：施工井台和护壁；本发明施工过程对孔壁保护较好，便于控制桩孔尺寸，避免了传统工艺孔径超宽过大问题，便于有效控制混凝土浇筑方量。
