Construction method of urban environment large-section cast-in-place comprehensive pipe gallery structure system
The invention relates to a construction method of a large-section cast-in-place comprehensive pipe gallery structure system in an urban area environment. The construction method comprises the following steps of installation of a fabricated pipe gallery reinforcement cage positioning and binding jig frame, binding of side wall steel bars, installation of a wall column formwork, installation of a composite formwork supporting system and pouring of concrete. The construction method has the beneficial effects that the construction method can adapt to all comprehensive pipe gallery structures with different cross section sizes, the construction time of a traditional formwork is greatly shortened, and a large amount of time and labor cost are saved; the side formwork system, the ground embedded part and the top plate formwork are ingeniously connected into a whole through the vertical supports, the inclined supports and the horizontal supports, and stress is reasonable and clear. Through the double-layer positioning aluminum plate consisting of the prefabricated aluminum plate, the end part positioning aluminum plate and the middle positioning aluminum plate, the accurate arrangement of each main rib is ensured; the embedded part installation system effectively solves the problem that holes need to be drilled in a formwork during traditional embedded part construction.
本发明涉及一种市域环境大断面现浇综合管廊结构体系的施工方法，包括以下步骤：装配式管廊钢筋笼定位绑扎胎架安装、侧墙钢筋绑扎、安装墙柱模板、安装复合式模板支撑体系、浇筑混凝土。本发明的有益效果是：可以适应任何横截面尺寸不同的综合管廊结构，大大缩短了传统模板的搭建时间，节省了大量的时间和人力成本；通过竖向支撑、斜撑和水平支撑巧妙地将侧模体系、地面预埋件和顶板模连成一体，受力合理明确；通过预制铝板和端部定位铝板、中间定位铝板组成的双层定位铝板保证了各主筋的精确布置；预埋件安装体系有效解决传统预埋件施工时需要在模板上钻孔等问题。
