Prefabricated assembly type structure for open cut rail transit station engineering and construction method
The invention discloses a prefabricated assembly type structure for open cut rail transit station engineering and a construction method. Two ends of a bottom plate prefabricated part and two ends of a top plate prefabricated part are connected with side wall prefabricated parts, first tenon joints are arranged at the two ends of the bottom plate prefabricated part and the two ends of the top plate prefabricated part correspondingly, second tenon joints are arranged at two ends of the side wall prefabricated parts correspondingly, and the first tenon joints and the second tenon joints are matched with prestressed cables (reinforcing steel bars) in a prestressed post-tensioning method in an inserted mode to form a prestressed concave-convex tenon grouting joint structure. The structure has the advantages that an integral column-free mode is adopted, the building space of a rail transit station project is released, equipment rooms are flexibly arranged, and passenger space experience is excellent; the bottom plate prefabricated part and the top plate prefabricated part are of longitudinal cavity structures, municipal pipelines and other equipment pipelines can be laid, the bottom plate prefabricated part and the top plate prefabricated part can also be used as ventilation air conditioner air pipes, underground space occupied by the equipment pipelines is reduced, and the cavities meet daily later operation and maintenance requirements; the rigidity and force transmission requirements of an assembly type joint are met; and a middle plate prefabricated part is in a prefabricated integral assembly type, and a rail top air duct prefabricated part is in clamping groove type assembly connection.
本发明公开一种明挖法轨道交通车站工程预制装配式结构及施工方法，底、顶板预制件两端通过与侧墙预制件连接，底、顶板预制件的两端均分别设置有第一榫接头，侧墙预制件的两端分别设置有第二榫接头，第一榫接头与第二榫接头插接配合预应力后张法预应力索(钢筋)构成预应力凹凸榫注浆接头结构。效果：采用整体无柱型式，释放轨道交通车站工程的建筑空间，设备用房布置灵活，乘客空间体验优越；底、顶板预制件采用纵向空腔结构，可铺设市政管线等设备管线、也可作通风空调风管使用，降低设备管线对地下空间占用，空腔满足日常后期运营维护要求；满足装配式接头刚度及传力要求；中板预制件为预制整体装配型式，轨顶风道预制件为卡槽式装配连接。
