Protection structure for early construction of subway tunnel in transportation junction and construction method
According to the protection structure and the construction method for early construction of the subway tunnel in the transportation junction, the later junction construction conditions are met, effective protection can be adopted for early construction of the subway tunnel, and the construction period and the project investment are greatly saved. Comprising a hub underground structure and a metro tunnel anti-floating protection structure, and a metro tunnel which is implemented in advance and operated is opened to be separated from the hub underground structure by adopting a shield tunneling method; the subway tunnel anti-floating protection structure comprises uplift piles and anti-floating beams. The uplift piles are arranged on the two sides of a subway tunnel at intervals in the line direction. The anti-floating beams are located above the subway tunnel and arranged at intervals in the line direction, and the anti-floating beams are fixedly connected with the uplift piles below the anti-floating beams. The hub underground structure comprises hub bearing platforms, bearing platform pile foundations and hub middle columns, the bearing platform pile foundations are arranged at intervals on the basis of the two sides of the subway tunnel in the line direction, the hub bearing platforms are arranged above the subway tunnel, tightly attached to the anti-floating beams below the hub bearing platforms and fixedly connected with the pile tops of the bearing platform pile foundations, and the hub middle columns are located on the hub bearing platforms.
一种地铁隧道在交通枢纽中先期施工的保护结构及施工方法，满足后期枢纽建设条件，且能对先期实施地铁隧道采取有效保护，大幅度节省建设工期和工程投资。包括枢纽地下结构和地铁隧道抗浮保护结构，采用盾构法先期实施并开通运营的地铁隧道与枢纽地下结构相脱离；地铁隧道抗浮保护结构包括抗拔桩和抗浮梁，抗拔桩于地铁隧道两侧沿线路方向间隔设置；抗浮梁位于地铁隧道上方，沿线路方向间隔设置，各抗浮梁与其下方的抗拔桩形成固定连接；枢纽地下结构包括枢纽承台、承台桩基和枢纽中柱，承台桩基于地铁隧道两侧沿线路方向间隔设置，枢纽承台设置于地铁隧道上方，与其下方的各抗浮梁紧贴且与承台桩基桩顶固结，枢纽中柱坐落于枢纽承台上。
