摘要
在深圳地铁安托山站—侨香站区间矿山法隧道超前支护施工中,由于采用了水平旋喷桩施工工艺,成功地解决了安-侨区间暗挖隧道在饱和粉细砂层及砾砂层中近距离穿越大断面雨水箱涵及φ500 mm次高压燃气管线的难题,节约了施工成本,充分显示了水平旋喷桩施工工艺在富水砂层浅埋暗挖隧道开挖预支护工程应用上的经济优势。文章论述了水平旋喷桩的工艺机理、适应性、优缺点以及在该工程中的应用效果。
By using horizontal jet grouting piles during the construction of advance support for the mined tunnel section between the Antuoshan and Qiaoxiang Stations,the project successfully passed through a large-section water box culvert in a saturated fine siltstone and grit layer and ？ 500 mm gas lines with intermediate pressure,cutting down on construction costs.This paper presents the technology mechanism as well as its adaptability,merits,deficiencies,and effects.
