Tunnel portal crossed pipe shed supporting structure
The invention relates to the technical field of tunnel supporting, in particular to a tunnel portal crossed pipe shed supporting structure, and solves the problem that the reinforcing stability of a tunnel portal of a bias high slope is insufficient. A tunnel portal cross type pipe shed supporting structure comprises a side slope soil body and further comprises a cover arch, a supporting retaining wall, a longitudinal pipe shed and a transverse pipe shed. The cover arch is poured at the bottom of the front side of the slope soil body; the supporting retaining wall is poured at the bottom of the left side of the slope soil body; the longitudinal pipe shed comprises a plurality of steel pipes A which are inserted into the cover arch and the side slope soil body in the longitudinal direction, and a plurality of grouting holes A are formed in the pipe wall of each steel pipe A; the transverse pipe shed comprises a plurality of steel pipes B which are transversely inserted into the supporting retaining wall and the side slope soil body, and a plurality of grouting holes B are formed in the pipe wall of each steel pipe B; the area defined by the supporting retaining wall, the transverse pipe shed and the side slope soil body is filled with a backfill body A. The method is suitable for reinforcing the tunnel portal of the bias high slope.
本发明涉及隧道支护技术领域，具体是一种隧道洞口交叉式管棚支护结构，解决了偏压高边坡的隧道洞口加固稳定性不足的问题。一种隧道洞口交叉式管棚支护结构，包括边坡土体，还包括套拱、支护挡墙、纵向管棚、横向管棚；套拱浇筑于边坡土体的前侧底部；支护挡墙浇筑于边坡土体的左侧底部；纵向管棚包括若干根沿纵向插设于套拱和边坡土体内的钢管A，且每根钢管A的管壁上均开设有若干个注浆孔A；所述横向管棚包括若干根沿横向插设于支护挡墙和边坡土体内的钢管B，且每根钢管B的管壁上均开设有若干个注浆孔B；支护挡墙、横向管棚、边坡土体围成的区域内填充有回填体A。本发明适用于偏压高边坡的隧道洞口加固。
