Construction method for building river-crossing subway underground station
The invention provides a construction method for building a river-crossing subway underground station, relates to the technical field of rail transit construction, and aims to solve the problems that the existing river-crossing subway underground station is low in construction efficiency and poor in long-term operation reliability. When the supporting structure is constructed, an upstream cofferdam is directly constructed, the strength of the cofferdam is improved, the anti-seepage capacity of the cofferdam is improved, a temporary supporting structure in the foundation pit supporting mechanism is designed to be a permanent structure, the anti-floating capacity of an underground subway station is improved, waste of construction materials is greatly reduced, and the reliability requirement for long-term operation of the station is met; the flow guide pipe is arranged for river water flow guide to meet drainage requirements and flood control requirements.
本发明提供一种用于修建跨河地铁地下车站的施工方法，涉及轨道交通施工技术领域，针对目前跨河地铁地下车站施工效率低且长期运行可靠性差的问题，在设置围堰后，处于上游的围堰兼做施工便道，在支护结构施工时直接于上游围堰施工，增加围堰的强度并提高其防渗透能力，将基坑支护机构中的临时支撑结构、临时支护结构设计为永久结构，提高地下地铁车站的抗浮能力，大大减少施工材料浪费，满足车站长期运行的可靠性要求，设置导流管进行河水导流，满足排水需求，满足防洪要求。
