Highway tunnel portal section collapsed mass slope protection reinforcing structure and construction method
The invention provides a highway tunnel portal section collapsed mass slope protection reinforcing structure. The highway tunnel portal section collapsed mass slope protection reinforcing structure comprises a tunnel, a step-shaped anchoring frame beam arranged on at least one side of the tunnel, a lower retaining wall, an end anti-slide pile and a long open cut tunnel. The stepped anchoring frame beam comprises multiple stages of frame beams distributed along a slope in a stepped mode, self-propelled anchor rods are arranged at lattice intersection points of the frame beams to be anchored to a mountain rock layer, net hanging grass planting protection is arranged in lattices, and net hanging spray ramming protection is arranged on a transition section between a tunnel upward slope and the multiple stages of frame beams. The lower retaining wall is an inclined retaining wall which is arranged at the toe of the side slope and inclines towards the side slope; the end anti-slide pile is arranged at the end of the hole; the long open cut tunnel comprises a first-level open cut tunnel, a second-level open cut tunnel and a third-level open cut tunnel. The protective structure is designed aiming at the collapsed mass side slope, and a series of technical problems of loose collapsed mass, bias pressure, high side slope, operation falling stone, greening and environmental protection and the like are effectively solved.
本发明提供了一种公路隧道洞口段塌滑体边坡防护加强结构，包括隧道、设于隧道至少一侧的阶梯状锚固框架梁、下部挡墙、端部抗滑桩和长明洞；所述阶梯状锚固框架梁包括沿边坡阶梯状分布的多级框架梁，在框架梁的框格交点处设置自进式锚杆锚固于山体岩石层，所述框格中设置挂网植草防护，所述隧道仰坡与多级框架梁之间的渐变段设置挂网喷夯防护；所述下部挡墙设置于边坡坡脚处的向边坡倾斜的倾斜式挡墙；所述端部抗滑桩设置于洞口端部；所述长明洞包括一级明洞、二级明洞和三级明洞。针对塌滑体边坡采用上述结构设计防护结构，有效解决松散塌滑体、偏压、高边坡、运营坠石、绿化环保等一系列技术难题。
