随着我国城镇化建设进程的加快,地铁建设也进入飞速发展中,在地铁建设及运营过程中出现了各种各样的问题,地下线道岔转辙机基坑积水问题尤为突出。为保证地铁运营安全,转辙机基坑排水设计变得至关重要。本文阐述了常用的转辙机基坑排水设计方法,在此基础上提出采用止回阀的方式进行转辙机基坑排水设计的方法。
With the acceleration of the process of urbanization in our country, the subway construction has also entered a rapid development. Various problems have arisen during the construction and operation of the subway. The problem of water accumulation in the basement pit of the switch wire machine in the underground line is particularly prominent. In order to ensure the safety of the MTR operation, the drainage design of the foundation pit has become crucial. This article elaborates the commonly used design method of foundation pit drainage of the switch machine, and on the basis of this, puts forward the method of using the check valve to design the foundation pit drainage design of the switch machine.
