Subway station construction method based on open caisson method
The invention is suitable for the technical field of constructional engineering, and provides a subway station construction method based on an open caisson method. A subway station tunnel is divided into an end open caisson area I, a side open caisson area I, a middle open caisson area, a side open caisson area II and an end open caisson area II. An open caisson is sunk in each of the end open caisson area I, the middle open caisson area and the end open caisson area II, an open caisson is sunk in each of the side open caisson area I and the side open caisson area II, and finally, joint treatment between the open caissons is performed to complete construction of the subway station. The enclosure structure does not need to be arranged, and engineering investment is reduced. Besides, when the construction environment is in a stratum with water, precipitation is not needed, underground water resources are protected, influence on the surrounding environment is small, and protection of theunderground ecological environment is facilitated.
本发明适用于建筑工程技术领域，提供了一种基于沉井法的地铁车站修建方法，将地铁车站隧道分隔形成端部沉井区一、侧部沉井区一、中部沉井区、侧部沉井区二、端部沉井区二，并首先在端部沉井区一、中部沉井区、端部沉井区二均下沉一个沉井，然后在侧部沉井区一和侧部沉井区二均下沉一个沉井，最后进行各沉井间的接缝处理，完成地铁站的修建。本发明无需设置围护结构，降低了工程投资。另外，当施工环境处于有水地层中时，无需降水，保护了地下水资源，对周边环境影响小，有利于地下生态环境的保护。
