Long spiral bagged fluid pile construction method
The invention relates to the field of civil engineering, in particular to a long spiral bagged fluid pile construction method in the field of geotechnical control engineering. The method mainly comprises the following steps of a) moving a long spiral drilling machine with a hollow drill rod (1) to a pile position; b) rotating the long spiral drill rod (1) to the depth of a pile bottom; c) injecting a fluid (5) into a seal bag (4) arranged in the hollow drill rod (1); and d) pulling out the long spiral drill rod, and leaving the seal bag (4) filled with the fluid (5) in soil. A bagged fluid pile can be quickly constructed in a soil body, the construction noise is low, the effects of zero slurry, zero vibration and zero soil squeezing are generated, the quality is easy to control, and the manufacturing cost is low.
本发明涉及土木工程领域，特别是土工控制工程领域中的一种长螺旋袋装流体桩施工方法，该方法主要步骤包括：a)将带有中空钻杆(1)的长螺旋钻机移至桩位；b)旋转长螺旋钻杆(1)至桩底深度；c)向置于中空钻杆(1)内的密封袋(4)内注入流体(5)；d)拔出长螺旋钻杆，并将充有流体(5)的密封袋(4)留置于土中，本发明可以快速在土体中施工完成袋装流体桩，施工噪音小，无泥浆，无振动，无挤土效应，质量易控，造价低。
