Landslide mass upper deformation road outer retaining wall reinforcing structure and construction method thereof
The invention discloses a landslide mass upper deformation road outer retaining wall reinforcing structure and a construction method thereof. The landslide mass upper deformation road outer retaining wall reinforcing structure is characterized in that a plurality of self-propelled hollow grouting anchor rods are arranged in a deformation retaining wall, a plurality of steel pipe piles which are internally provided with steel bar bundles and are poured and filled are vertically arranged at the bottom of the outer side of the deformation retaining wall, stepped enlarged foundations are fixed at the tops of the steel pipe piles; a fitting slope reinforcing layer is poured on the surface of the deformation retaining wall; and at least two rows of anchor cables connected with the ground are fixed on the deformation retaining wall. According to the construction method of the landslide mass upper deformation road outer retaining wall reinforcing structure, reinforcing construction can be conducted on the deformation retaining wall on the premise that an existing retaining wall is not dismantled, the landslide mass on the lower portion of the deformation retaining wall is deeply reinforced, the foundations are expanded after the anti-sliding force of a side slope is improved, half-range communication can be achieved, road breaking construction is not needed, the sliding resistance of the side slope is improved, the natural side slope is reinforced, and the phenomenon of uneven settlement or overturning of the retaining wall foundations can be effectively prevented.
本发明公开了滑坡体上部变形公路外挡加固结构及施工方法，滑坡体上部变形公路外挡加固结构在变形挡墙内布置多根自进式中空注浆锚杆，变形挡墙的外侧底部竖直设置多根内置钢筋束并浇注填充的钢管桩，钢管桩的顶部固定有台阶式的扩大基础；变形挡墙的表面浇筑有贴坡加固层；变形挡墙上固定至少两排与地面相连的锚索。本发明所公开的滑坡体上部变形公路外挡加固结构的施工方法可在不拆除现有挡墙的前提下对变形挡墙进行加固施工，本发明对变形挡墙的下部滑坡体进行深层加固，在提高边坡的抗滑力后再扩大基础，可以实现半幅保通，不需要断道施工，提高了边坡的抗滑力、加固了自然边坡，能够有效防止挡墙基础出现不均匀沉降或倾覆现象的发生。
