Lining supporting system for tunnel framing reconstruction tunnel bottom structure and construction method thereof
The invention discloses a lining supporting system for a tunnel framing reconstruction tunnel bottom structure and a construction method thereof. The supporting system comprises an inverted arch lining, a primary support, steel flower tube lock feet, a blocking isolation wall and a pre-reinforcing pile, wherein the inverted arch lining and the primary support are arranged at the tunnel bottom, thesteel flower tube lock feet are driven into surrounding rock from side walls on the two sides, and the blocking isolation wall and the pre-reinforcing pile are positioned above and below a central ditch correspondingly; the inverted arch lining comprises two half-range inverted arch linings which are symmetrically arranged in the transverse direction of a tunnel; the primary support comprises twohalf-range primary supports which are symmetrically arranged in the transverse direction of the tunnel; and the pre-reinforcing pile is fixedly connected with the two half-range inverted arch liningsand the two half-range primary supports. According to the lining supporting system for the tunnel framing reconstruction tunnel bottom structure and the construction method thereof, the risk of framing reconstruction of the tunnel bottom structure in the operating state of the tunnel is reduced in the form of framing excavation and framing support, the operation time of reconstruction of the tunnel bottom structure can be not limited, the overhead reinforcing procedure of a steel cushion beam is omitted, interference to a track structure is reduced, and the construction progress in the operating state can be greatly improved on the premise of ensuring safety.
本发明公开了一种隧道分幅重构隧底结构的衬砌支护体系及其施工方法，其中支护体系包括设置在隧底的仰拱衬砌、初期支护，由两侧边墙打入围岩中的钢花管锁脚，以及分别位于中心水沟上、下方的封堵隔离墙和预加固桩，仰拱衬砌包括沿隧道横向对称设置的两个半幅仰拱衬砌，初期支护包括沿隧道横向对称设置的两个半幅初期支护，预加固桩分别与两个半幅仰拱衬砌、两个半幅初期支护固结。本发明通过“分幅开挖、分幅支护”的形式来降低隧道在营运状态下分幅重构隧底结构的风险，重构隧底结构作业时间可以不受限制，减少了钢垫梁架空加固工序，减少了对轨道结构的干扰，在保证安全的前提下能极大地提高运营状态下施工进度。
