Abstract 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.
