Construction method for breaking and transforming roof of existing subway station
The invention discloses a construction method for breaking and transforming a roof of an existing subway station, which relates to the technical field of underground engineering and comprises the following steps of: newly building a station roof above the roof of the existing station; temporary concrete side walls are newly built, so that a newly-built station top plate is connected with an existing station enclosure and finally acts on an existing top plate, and the anti-floating safety of the station is ensured; a station structure is newly built, and all structural layers of the newly built station and the existing station are transformed and connected so that the existing station structure can be stable; the roof of the existing station is output after being cut and broken; after the top plate of the existing station is completely broken, the temporary concrete side wall is dismantled so that the newly-built station can communicate with the existing station; according to the embodiment of the invention, after the newly-built station and each structural layer of the existing station are transformed and connected, the roof structure is broken, the stability of the existing structure is ensured, and compared with the prior art that the existing station roof is supported by directly using a scaffold, the safety of the existing structure and operation is ensured.
本发明公开了一种既有地铁车站顶板破除改造的施工方法，涉及地下工程技术领域，包括如下步骤，在既有车站的顶板上方新建车站顶板；新建临时混凝土侧墙以使得新建车站顶板与既有车站围护连接，最终作用于既有顶板，确保车站抗浮安全；新建车站结构，并将新建车站与既有车站的各结构层进行改造连接以使得既有车站结构稳定；对既有车站顶板进行切块破除后输出；在既有车站顶板全部破除后，拆除临时混凝土侧墙以使得新建车站与既有车站实现连通；本发明实施例在新建车站与既有车站的各结构层实现改造连接后，再进行顶板结构的破除，保证了既有结构的稳定，相比于现有技术中直接利用脚手架对既有车站顶板进行支撑，保证了既有结构以及运营的安全性。
