Construction method of high-pressure jet grouting powerful mixing pile suitable for floating pebble stratum
The invention relates to the field of civil engineering, in particular to a construction method of a high-pressure jet grouting intense stirring pile suitable for a floating pebble stratum. Comprising the following steps: staking out and fixing a pile position in survey, placing a double tubular pile machine in place and preparing cement grout, sinking, stirring and spraying to a pile end, stirring and lifting the sprayed grout to a pile top, re-stirring and spraying to sink to the pile end, re-stirring and lifting the sprayed grout to the pile top, and shifting the double tubular pile machine. According to the floating pebble bed high-pressure jet grouting powerful mixing pile, the characteristics of a high-pressure jet grouting pile and a cement mixing pile are fully combined, and meanwhile, the equipment and technical defects that a traditional high-pressure jet grouting pile cannot be effectively cut into a pile in a floating pebble bed and a traditional cement mixing pile cannot be mixed and formed in the floating pebble bed are overcome. The method can be used for anti-seepage wall construction, a traditional occlusion cast-in-place pile and diaphragm wall technology is replaced, and due to the fact that cement grout is adopted for construction, the construction cost can be greatly reduced, and the construction period can be greatly shortened.
本发明涉及土木工程领域，具体涉及一种适用于漂卵石地层的高压旋喷强力搅拌桩的施工方法，包括以下步骤：测量放样、定桩位→二重管桩机就位、制备水泥浆液→下沉搅拌喷浆至桩端→喷浆搅拌提升至桩顶→复搅喷浆下沉至桩端→喷浆复搅提升至桩顶→二重管桩机移位。本发明的漂卵石层高压旋喷强力搅拌桩充分结合高压旋喷桩和水泥搅拌桩的特点，同时克服了传统的高压旋喷桩在漂卵石层无法有效切割成桩和传统水泥搅拌桩无法在漂卵石层搅拌成形的设备和技术缺陷。本发明可以用于防渗墙施工，替代传统工艺的咬合灌注桩、地连墙工艺，因其采用水泥浆液施工，其施工成本和工期可大幅度降低。
