Structure for preventing tunnel portal landslide
The invention provides a structure for preventing and treating tunnel portal landslide, and relates to the technical field of tunnel portal roadbed excavation slope construction technologies, the structure comprises various measures such as clearing and unloading, drainage, anti-slide piles, anchor pipe frame beams and micro piles, a plurality of steel anchor pipes are arranged, and the steel anchor pipes are distributed in a matrix shape and are used for being inserted into a hillside body; the multiple anti-slide piles are used for being sequentially arranged in rows and are arranged on the slope platforms of all levels. The multiple micro piles are used for being sequentially distributed at the bottom of the hillside body at intervals, and the multiple micro piles are located on the sides, away from the hillside body, of the anti-slide piles. The technical problems that in the prior art, in the tunnel construction process, the technical means for treating slope landslide at the tunnel portal is single, and the effect is poor are solved.
本发明提供一种防治隧道洞口滑坡的结构，涉及隧道洞口处路基挖方边坡施工技术的技术领域，包括清方卸载、排水、抗滑桩、锚管框架梁、微型桩等多种措施，钢锚管设有多个，且多个钢锚管呈矩阵状分布，且多个钢锚管用于插接在山坡本体内；抗滑桩设有多个，且多个抗滑桩用于依次成排状布置，设置于各级边坡平台上；微型桩设有多个，多个微型桩用于依次间隔分布于山坡本体的底部，且多个微型桩位于抗滑桩远离山坡本体的一侧。本发明缓解了现有技术中存在的隧道施工过程中在隧道洞口处处置边坡滑坡技术手段单一且效果差的技术问题。
