Prestress construction method for co-construction of subway station and municipal tunnel
The invention relates to the technical field of underground engineering technology, in particular to a prestress construction method for co-construction of a subway station and a municipal tunnel, which comprises the following steps: constructing a cover plate, a lane side wall and a lane hanging wall, and reserving a prestress channel; vertical supporting nodes and vertical supports are connected with a municipal tunnel bottom plate and all layers of plates of a subway station, temporary transverse concrete supports are erected, when the station structure meets the strength requirement, temporary steel pipe concrete columns and the temporary transverse concrete supports are dismantled, and the internal structure of the driving tunnel is constructed; through the haunching under the lane plate on one side of the side wall and the prestress effect of the inner side wall of the lane, the design of stand columns is reduced, and the in-station space is increased to the maximum extent. Through combined construction of the subway station and the municipal tunnel, engineering waste can be effectively avoided, the influence on road traffic is reduced, and the method has wide application prospects.
本发明涉及地下工程技术技术领域，尤其涉及一种地铁车站与市政隧道共建的预应力施工方法，包括：施工盖板与车道侧墙与车道吊墙，并预留预应力通道；利用竖向支撑节点、竖向支撑与市政隧道底板及地铁车站各层板连接，架设临时横向混凝土支撑，当车站结构达到强度要求时，拆除临时钢管混凝土柱与临时横向混凝土支撑，进行行车隧道内部结构施工，通过侧墙一侧车道板下加腋及车道内侧墙预应力作用，减少立柱的设计，最大限度提升了站内空间。本发明通过地铁车站及市政隧道合建，可有效避免工程浪费，减少对道路交通的影响，有着较为广阔的应用前景。
