Tubular pile hole following introduction hole forming method for deep sand layer geology
The invention belongs to the technical field of bridge construction, and particularly relates to a deep sand layer geological pipe pile hole following introduction hole forming method. In the process of hammering and forming the pipe pile, the previous pipe pile is driven underground, and a reserved pile head is exposed out of the ground for pile extension, hole guiding for soil taking and soil loosening are conducted in the pipe pile, the hole is guided to the pile bottom elevation of the next pipe pile, the next pipe pile is connected with the previous pipe pile and then is guided in through a heel hole, the tail pipe pile is driven underground to the original ground, and hole guiding for soil taking and soil loosening are conducted in the pipe pile. And guiding the hole to the designed pile bottom elevation, completing the hole guiding, installing a pile feeder, and feeding the pile to the designed elevation. According to the deep and thick sand layer geology pipe pile following hole introduction and hole forming method, rotary drilling rig equipment is modified, pipe pile following hole introduction of different heights is achieved, the hole introduction depth is greatly increased, and the construction work efficiency and progress are improved; the construction quality of the pipe pile is guaranteed, the hammering number is reduced, energy consumption is saved, and the construction cost is reduced.
本发明属于桥梁施工技术领域，具体涉及一种深厚砂层地质管桩跟孔引进成孔方法；管桩锤击成桩过程中，前一节管桩打入地下并预留桩头露出地面用于接桩，管桩内引孔取土、松土，引孔至后一节管桩的桩底标高，后一节管桩与前一节管桩连接后跟孔引进，末节管桩打入地下至原地面，管桩内引孔取土、松土，引孔至设计桩底标高，引孔完成，安装送桩器，送桩至设计标高。本发明提供的一种深厚砂层地质管桩跟孔引进成孔方法，通过对旋挖钻机设备进行改制，实现了不同高度管桩跟孔引进，大大增加了引孔深度，提高了施工工效与进度；保证了管桩的施工质量，减少了锤击数量，节约了能源消耗，降低施工成本。
