Low displacement excavation method for high slope road
The invention discloses a high slope road low displacement excavation construction method which comprises the following steps that S1, soil filling is conducted on a roadbed slope above a foundation pit to be excavated, a filling soil layer is formed, and the height of the filling soil layer reaches the middle of the roadbed slope; s2, row piles are constructed at the intersection of the roadbed slope and the surface of the filling soil layer, the row piles are perpendicular to the ground, and the row piles extend to the position below the ground; and S3, the surface of the filling soil layer is vertically excavated in the underground direction till a foundation pit is formed. Large displacement of the roadbed slope in the excavation process can be avoided, instability of the roadbed slope in the foundation pit excavation process is prevented, and the steep slope construction retaining structure problem is solved.
本发明公开了一种高边坡道路低位移开挖工法，包括如下步骤：S1、在待挖基坑上方对路基边坡进行填土，形成填充土层，所述填充土层高度达到所述路基边坡中部；S2、在所述路基边坡与所述填充土层表面相交处施工排桩，所述排桩与地面垂直，所述排桩延伸进地面下方；S3、从所述填充土层表面沿地下方向垂直开挖，直至形成基坑。本发明能够避免路基边坡在开挖的过程中产生较大位移，防止基坑开挖过程中路基边坡失稳，解决了陡坡施工支档结构问题。
