Construction and plugging method for preformed pouring hole in subway station roof
The invention belongs to the field of subway station structure construction, particularly relates to a construction and plugging method for a preformed pouring hole in a subway station roof. The construction and plugging method aims to reserve the pouring hole in the station roof and facilitate pouring of a concrete structure in a station. The construction and plugging method comprises the steps of erecting a formwork of the subway station roof and binding steel bars, manufacturing a rigid water stop sleeve for plugging the preformed hole, rechecking positioning of the preformed pouring hole in the subway station roof, laying reinforcing steel bars in the preformed pouring hole area, installing the rigid water stop sleeve in the preformed pouring hole, and pouring subway station roof concrete; and determining the pavement elevation, building a pouring well in the upper area of the preformed pouring hole, installing a well lid at a well opening of the pouring well, guiding a pump pipe to the lower area of the station roof, and plugging the preformed pouring hole in the roof and constructing a waterproof layer of the area after pouring of internal structures of the subway station is completed. According to the method, the influence of subway station construction on urban traffic is reduced to a great extent.
本发明属于地铁车站结构施工领域，具体涉及一种用于地铁车站顶板浇筑预留孔的施工及封堵方法，目的是用于在车站顶板上留设浇筑孔，方便车站内部结构混凝土结构的浇筑，包括地铁车站顶板的支模及钢筋绑扎，制作用于预留孔封堵的刚性止水套管，对地铁车站顶板浇筑预留孔的定位进行复核，并在浇筑预留孔区域铺设加强钢筋，在浇筑预留孔内安装刚性止水套管，浇筑地铁车站顶板混凝土；确定路面标高并在浇筑预留孔的上部区域内砌筑浇筑井，在浇筑井的井口安装井盖，将泵管引至车站顶板的下部区域，地铁车站内部结构浇筑完成后，对顶板浇筑预留孔进行封堵并施做该区域的防水层。本发明较大程度地减小了地铁车站施工对城市交通的影响。
