Cast-in-situ bored pile construction technology
The invention discloses a cast-in-situ bored pile construction technology, and belongs to the technical field of building construction. The technology comprises the steps that S1, equipment inspection is submitted, and drilling machine drill bit equipment enters a site; s2, pile position lofting; s3, embedding a pile casing; s4, drilling and positioning, wherein the deviation of the position of a drilling machine is not larger than 2 cm; s5, drilling holes and recording footage; s6, final hole inspection, including hole depth measurement and primary hole cleaning; s7, the mud index, the drilling inclination, the thickness of a sinking layer and the hole diameter are measured; s8, the woven reinforcement cage and the slurry guide pipe are put down, and secondary hole cleaning is conducted; s9, the sediment thickness is checked again, and the mud index is measured; s10, underwater concrete is poured; s11, measuring: recording the concrete surface elevation and the concrete quantity, and measuring the concrete slump; s12, after concrete pouring is completed, the elevation of the top face of the concrete is measured; s13, dismounting and pulling the pile casing; and S14, the pile head is cleaned. Through two times of hole cleaning, the index is reached before pouring, the problem that the reinforcement cage floats upwards is solved by fixing the reinforcement cage and the hole opening, the quality of a later-stage pouring pile is better, and engineering is safe and reliable.
本发明公开了一种钻孔灌注桩施工工艺属于建筑施工技术领域，包括S1：设备报验，钻机钻头设备进场；S2：桩位放样；S3：埋置护筒；S4：钻孔定位，钻机位置的偏差不大于2cm；S5：钻孔并记录进尺；S6：终孔检查，包括测孔深和一次清孔；S7：测泥浆指标、钻孔倾斜度、沉底层厚度和孔径；S8：将编织好的钢筋笼和导浆管下放并二次清孔；S9：再次检查沉淀厚度，测泥浆指标；S10：灌注水下混凝土；S11：测量、记录混凝土面标高、混凝土数量和测混凝土塌落度；S12：混凝土浇筑完毕，测混凝土顶面标高；S13：拆、拔护筒；S14：清理桩头。通过两次清孔，在灌注前达到指标，钢筋笼通过与孔口固定解决了钢筋笼上浮的问题，是后期灌注桩质量更好，工程安全可靠。
