Subway station and municipal tunnel co-construction flat slab construction method
The invention relates to a flat slab construction method for co-construction of a subway station and a municipal tunnel, which comprises the following steps of: sequentially constructing an enclosure structure, a stand column pile and an uplift pile on the basis of a cover-excavation reverse construction method, and sequentially constructing a station top plate and a top beam above the enclosure structure, the stand column pile and the uplift pile; 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, permanent steel pipe concrete column supporting nodes are arranged on the municipal tunnel bottom plate and all layers of plates of a station correspondingly, and flat slab floors are arranged on the municipal tunnel bottom plate and connected with steel pipe concrete columns. According to the scheme, the construction method that the subway station and the municipal tunnel are jointly built in an up-down overlapping mode and the station main body structure and the municipal tunnel structure are synchronously designed and synchronously implemented is adopted, engineering waste can be effectively avoided, the influence on road traffic is reduced, and the construction method has wide application prospects and is worthy of popularization. And the popularization value is high.
本发明涉及一种地铁车站与市政隧道共建的无梁楼盖施工方法，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永久钢管混凝土柱支撑节点，市政隧道底板设置无梁楼盖与钢管混凝土柱连接，其余各层永久钢管混凝土柱分别与纵梁与横梁连接，方案采用“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施工方法，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，推广价值较高。
