Tunnel construction method suitable for urban underground boulder area
The invention discloses a tunnel construction method suitable for an urban underground boulder area. The tunnel construction method comprises the steps that firstly, full-section grouting reinforcement is conducted on a tunnel face soil body; secondly, an advanced pipe shed support is arranged at the position of a tunnel portal; and thirdly, boulder removing construction of the horizontal drill of the down-the-hole hammer is conducted. According to the construction method, the shallow-buried excavation method and the down-the-hole hammer horizontal drilling boulder removal are combined, the risk of manual operation existing in the shallow-buried excavation method can be avoided, horizontal drilling crushing can be conducted on a soil layer with complex geology and boulder, the content of large rock in the stratum is reduced, it is guaranteed that the pipe jacking tunneling posture is controllable, and the construction efficiency is improved. And safe and efficient construction and smooth penetration of the jacking pipe are ensured.
本发明公开一种适用于城市地下孤石区域的隧道施工方法，其包括：步骤一、对掌子面土体进行全断面注浆加固；步骤二、洞门处设置超前管棚支护；步骤三、潜孔锤水平钻孤石清除施工。本发明的施工方法结合了浅埋暗挖法和潜孔锤水平钻孤石清除两种施工工艺，不仅能解决浅埋暗挖法存在人工作业的风险，还可以对地质复杂且存在孤石土层进行水平钻孔破碎，减少地层中大块岩石含量，保证顶管掘进姿态可控，确保顶管安全高效的施工及顺利贯通。
