Co-construction method for subway station and municipal tunnel
The invention relates to a metro station and municipal tunnel co-construction method which comprises the following steps: sequentially constructing an enclosure structure, upright post piles and uplift piles on the basis of a cover-excavation top-down construction method, and sequentially constructing a station top plate and a top beam above the enclosure structure, the upright post piles and the uplift piles; after a foundation pit is excavated to the designed elevation position below a municipal tunnel bottom plate, the municipal tunnel bottom plate, longitudinal beams and temporary transverse concrete supports are poured, vertical structural column supporting nodes are arranged on the municipal tunnel bottom plate and all layers of plates of a station respectively, structural columns are connected with the longitudinal beams and transverse beams, and the subway station and the municipal tunnel are jointly built in an up-down overlapping mode. A method for synchronously designing and synchronously implementing a station main body structure and a municipal tunnel structure is adopted, a subway station is constructed by adopting a cover-excavation top-down construction method, road traffic is recovered after a cover plate reaches the strength, municipal tunnel equipment room construction is combined, municipal tunnel internal structure pouring is synchronously implemented, operation is put into operation in advance, and the influence on ground traffic is reduced.
本发明涉及一种地铁车站与市政隧道共建施工方法，包括：基于盖挖逆作法依次施作围护结构、立柱桩与抗拔桩后，在所述围护结构、立柱桩与抗拔桩上方依次施作车站顶板与顶梁；开挖基坑至市政隧道底板下设计标高处后，浇筑市政隧道底板、纵梁与临时横向混凝土支撑，市政隧道底板及车站各层板分别设置竖向结构柱支撑节点，结构柱与纵梁与横梁连接，采用“上下重叠”合建地铁车站、市政隧道，同步设计、同步实施车站主体结构及市政隧道结构的方法，地铁车站采用盖挖逆作法施工，盖板达到强度后，恢复路面交通，结合市政隧道设备房间建设，同步实施市政隧道内部结构浇筑，提前投入运营，减小对地面交通的影响。
