Box type concrete assembly type rail top air duct and construction method
The invention belongs to the field of rail transit, and particularly relates to a box type concrete assembly type rail top air duct and a construction method.The rail top air duct comprises a left prefabricated side plate, a right prefabricated side plate, a prefabricated bottom plate and a prefabricated top plate, cattle leg parts are arranged on the upper portions of the left prefabricated side plate and the right prefabricated side plate, and side plate lifting lugs horizontally extending inwards are arranged at the bottoms of the left prefabricated side plate and the right prefabricated side plate; the prefabricated top plate is supported and fixed by cattle legs on the two sides, and the side plate lifting lugs on the left side and the right side are connected with the prefabricated bottom plate through post-cast strips. The top plate unit joint seams or the bottom plate unit joint seams and the side plate unit joint seams are arranged in a staggered manner; the side plates, the top plate and the bottom plate of the box-type prefabricated rail top air duct are prefabricated respectively, and the side plates, the top plate and the bottom plate are small in size, light in weight and convenient to load and transport; compared with integral installation of a box type prefabricated rail top air duct, the split type prefabricated part is light in weight and lower in construction difficulty, and the limitation that a conventional cast-in-place rail top air duct and a prefabricated rail top air duct are difficult to construct and large in construction difficulty can be overcome.
本发明属于轨道交通领域，具体涉及一种箱型混凝土组装式轨顶风道及施工方法，所述轨顶风道包括左预制侧板、右预制侧板、预制底板及预制顶板，所述左预制侧板、右预制侧板的上部设置有牛腿部、底部设置有向内水平延伸的侧板挑耳，所述预制顶板被两侧的牛腿部支撑固定，左右两侧的侧板挑耳通过后浇带与预制底板连接；顶板单元节接缝或底板单元节接缝与侧板单元节接缝交错布置；本发明将箱型预制轨顶风道的侧板、顶板和底板分别预制，它们各自体积小、重量轻，便于装运；相比于箱型预制轨顶风道整体安装，分体式预制件重量轻、施工难度更小，可克服常规现浇轨顶风道和预制轨顶风道施工困难、施工难度大的局限。
