摘要
结合北京市轨道交通16号线工程实例,研发了一种采用插销式反力支座及多孔式钢轨组成的推进系统,配合后配套支撑系统、多方式盾构轨迹控向系统,使盾构整机在狭小空间内快速平移过站,解决了盾构主机与后配套分离拖拉过站再组装的施工难题。形成了一套完整的盾构整机过地铁车站的施工工法和关键技术。此外,电瓶车组轨道的铺设与盾构机的维修保养在过站过程中同步进行,有效缩短了工期并降低了成本。
Based on the engineering practice of Subway Line 16 in Beijing,a propulsion system consisting of a pin counterforce device and a perforated steel rail is developed.The backup device support system was combined with the multi-method shield trajectory control system to enable the whole shield machine’s quick translating metro station in confined space,solving the problem of separating and then reassembling of the shield mainframe machine and the backup device dragging after translating the metro station.A complete construction method and a key technology are formed for shield’s translating metro station.In addition,the laying of battery-tram rail and the maintenance of shield machine can be carried out simultaneously when translating metro station,which can effectively shorten the construction period and reduce the cost.
