老路路堑边坡防护拆除施工在高速公路改扩建工程施工中占据着重要的位置,影响着老路的通行安全。现结合连霍高速公路改扩建工程老路路堑边坡防护拆除施工经验,浅谈老路路堑边坡防护拆除施工控制措施。原老连霍高速公路路堑边坡防护采用浆砌片石、浆砌块石护面墙全硬化的防护方式,部分高填方路段下边坡采用浆砌片石防护,边沟采用砼预制块、浆砌片石防护,这次路基改扩建加宽拆除的边坡防护工程圬工数量较大。1.边坡防护拆除施工措施原有老路基路堑采用的是浆砌片石、浆砌块石、砼挂板全防护,部
Old road cutting slope protection and demolition construction in the highway reconstruction project occupies an important position, affecting the safety of the old road. In combination with the construction experience of the old road cutting slope protection and reconstruction of the Lianhuo Expressway reconstruction project, the control measures of the protective and dismantling construction of the old road cutting slope are discussed. The original Lao-Huo Expressway cutting slope protection using mortar masonry, masonry stone masonry wall hardening method of protection, some high-fill road slope with mortar rubble protection, ditches using concrete prefabricated block, masonry Stone protection, the roadbed to expand the demolition of the slope protection project to expand a large number of workers. 1. Slope protection and removal of construction measures The original old roadbed is used mortar rubble, masonry stone, concrete siding full protection, Department
