Construction method of construction system of complex interactive silty-fine sand layer super-long large-diameter pile foundation
The invention relates to a construction method of a construction system of a complex interactive silty-fine sand layer super-long large-diameter pile foundation. The construction method comprises the steps that construction preparation is conducted; positioning and sinking the steel casing; drilling to form a hole and cleaning the hole; manufacturing a reinforcement cage; and lowering and mounting the reinforcement cage. The method has the beneficial effects that the reinforcement cage shaping jig frame is adopted for manufacturing the reinforcement cage, the construction speed is high, and the machining quality is stable and reliable; the main reinforcements are uniformly distributed, and the main reinforcements between the reinforcement cages are mechanically connected, so that the construction cost is reduced; the on-site construction quality and efficiency are improved, the on-site construction difficulty is reduced, the hole forming stability of the cast-in-situ bored pile is ensured, and construction operation is convenient, environmentally friendly, safe and reliable; and by adopting the settling pond slurry cyclic regeneration system, the sediment is treated by the slurry purifier, the content of the slurry discharged into the hole again is small, the repeated slag discharge amount is reduced, the technical index of the slurry is good, and the hole cleaning effect is good.
本发明涉及一种复杂交互粉细砂层超长大直径桩基的施工体系的施工方法，包括步骤：施工准备；钢护筒定位下沉；钻进成孔及清孔；钢筋笼制作；钢筋笼下放安装。本发明的有益效果是：本发明采用钢筋笼定型化胎架来制作钢筋笼，施工速度快，加工质量稳定可靠；主筋分布均匀，钢筋笼之间的主筋采用机械连接，降低了施工成本；提高现场施工质量和效率，降低现场施工难度，确保钻孔灌注桩成孔稳定性，施工操作方便、绿色环保、安全可靠；采用的沉淀池泥浆循环再生系统，使得沉渣经过泥浆净化器处理，重新排入孔的泥浆含渣量小，减少重复排渣量，泥浆技术指标好，清孔效果佳。
