摘要
隧道穿越深厚土层采用桩筏基础加固时,为解决隧道洞内桩基快速安全施工及运输通道畅通等问题,研究了通过改装低空旋挖钻机进行隧道内桩基成孔技术。实际应用效果表明,该技术为隧道内桩筏基础施工提供了施工保障,加快了施工速度,保证了施工安全,可为同类工程提供借鉴。
In order to solve the problems of fast and safe construction of pile foundation and unblocked transportation passage in tunnel when the tunnel passes through deep soil layer and is reinforced by pile raft foundation,the drilling technology of pile foundation in tunnel is studied by retrofitting low-level rotary drilling rig.The practical application results show that this technology can provide guarantee for the construction of pile raft foundation in tunnel,accelerate the construction speed,ensure the construction safety,and can provide reference for similar projects.
