Subway station over crossing existing tunnel and construction method thereof
The invention relates to the technical field of rail transit, and provides a subway station over crossing an existing tunnel. The subway station comprises a bearing body, the bearing body is providedwith a supporting platform and a through channel for the existing tunnel to pass through, and a platform layer and a station hall layer are sequentially constructed above the supporting platform. Theinvention further provides a construction method of the subway station over crossing the existing tunnel, and the construction method comprises the following steps that S1, the bearing body is constructed above the existing tunnel, so that the existing tunnel penetrates through the through channel of the bearing body; S2, a newly-built tunnel is constructed above the supporting platform of the bearing body; and S3, after construction of the newly-built tunnel is completed, the station hall layer is constructed above the newly-built tunnel. The platform layer and the station hall layer are constructed on the bearing body, the station hall layer and the platform layer are constructed through an underground excavation method, evacuation and communication of passengers are guaranteed through the station hall layer, normal operation of a train is guaranteed through the platform layer, and engineering risks are greatly reduced.
本发明涉及轨道交通技术领域，提供了一种上跨既有隧道的地铁车站，包括承载体，所述承载体具有支撑平台以及供既有隧道穿过的贯穿通道，于所述支撑平台上方依次施作站台层和站厅层。还提供一种上跨既有隧道的地铁车站的施工方法，包括如下步骤：S1，在既有隧道上方施工承载体，使所述既有隧道从所述承载体的贯穿通道中穿过；S2，于所述承载体的支撑平台的上方施工新建隧道；S3，待所述新建隧道施工完成后，再于所述新建隧道上方施工站厅层。本发明通过在承载体上施工站台层和站厅层，其中站厅层和站台层通过暗挖法来进行施工，站厅层保证乘客的疏散与连通，站台层保证列车的正常运行，大大降低了工程风险。
