Construction method of cast-in-place concrete full-protection foam light soil widening embankment
The invention relates to a construction method of a cast-in-place concrete full-protection foam light soil widening embankment, the construction of a standard section widening embankment and a bridgehead section widening embankment is synchronously carried out, and the construction of the standard section widening embankment comprises the following steps: excavating a foundation trench of the standard section widening embankment, processing a prefabricated part, and constructing a prefabricated cantilever type reinforced concrete retaining wall. The construction method comprises the steps of gravel replacement and filling construction, foam concrete pouring, limestone soil leveling layer construction, precast concrete inner wall construction and cast-in-place concrete full-protection construction. The prefabricated side ditch has the beneficial effects that the prefabricated concrete inner wall is mounted below the drainage hole of the prefabricated cantilever type reinforced concrete protection wall, and then the prefabricated side ditch outer wall is mounted; the winch pulls the hanging rod to drive the movable steel formwork to conduct cast-in-place concrete full-protection construction. And the movable operation platform structure is fixedly connected with the prefabricated cantilever type reinforced concrete retaining wall through the overturn-preventing pull rod, so that the construction efficiency and the construction quality of the newly-spliced wide embankment are improved.
本发明涉及一种现浇混凝土全防护泡沫轻质土拼宽路堤的施工方法，同步进行标准段拼宽路堤和桥头段拼宽路堤的施工，标准段拼宽路堤的施工包括步骤：标准段拼宽路堤基槽开挖，预制构件加工，预制装配悬臂式钢筋混凝土护壁施工，换填碎石施工，泡沫混凝土浇筑，石灰土找平层施工，预制混凝土内壁施工，现浇混凝土全防护施工。本发明的有益效果是：在预制装配悬臂式钢筋混凝土护壁的泄水孔下方安装预制混凝土内壁，再安装预制边沟外壁；卷扬机拉动吊杆带动移动钢模板进行现浇混凝土全防护施工；移动式操作平台结构通过防倾覆拉杆与预制装配悬臂式钢筋混凝土护壁固定连接，提高了新拼宽路堤施工效率及施工质量。
