Green energy-saving engineering pile construction method and composite pile construction method thereof
The invention belongs to the field of soft soil foundation treatment, and particularly relates to a green energy-saving engineering pile construction method which comprises the following steps: a liquid storage hole forming step: digging a soil body at the top of a preset position to a preset depth to form a liquid storage hole; a soil body crushing step: drilling downwards from the bottom of the liquid storage hole to crush the soil body, and injecting liquid to a first depth position to form a liquid fluid channel; a dry material replacement step: injecting a dry or semi-dry curing material from the bottom of the liquid-state fluid channel and lifting the dry or semi-dry curing material to a second depth position; the slurry replaced from the liquid-state fluid channel is sucked into the liquid storage hole, the water content of the pile body can be remarkably reduced, the strength and the consolidation efficiency of the engineering pile are improved, and ground environment pollution is avoided. The invention further provides a composite pile construction method which comprises the green energy-saving engineering pile construction method and the step that before the engineering pile is not solidified, a core pile is arranged in the engineering pile, the core pile is a precast pile or a cast-in-place pile or a steel pile or a cement mixing pile, and the bearing capacity of a foundation is improved.
本发明属于软土地基处理领域，尤其涉及一种绿色节能工程桩工法，包括储液孔成型步骤：于预定位置的顶部挖除土体至预定深度形成储液孔；土体破碎步骤：于储液孔孔底起向下进钻粉碎土体并注入液体至第一深度位置形成液态流体通道；干料置换步骤：自液态流体通道底部起注入干性或半干性固化料并提升至第二深度位置；以及浆液排除步骤：于储液孔内抽吸从液态流体通道内置换出的浆液，能够显著降低桩体的含水量，提高工程桩的强度和固结效率，避免造成地面环境污染。本发明还提供一种复合桩施工方法，包括如上所述的绿色节能工程桩工法，以及在工程桩未凝固前，在工程桩内设置芯桩，芯桩为预制桩或灌注桩或钢桩或水泥搅拌桩，提高地基的承载力。
