本文从地铁2号线石门一路车站建设的施工和管理,对车站施工和环境保护的问题作探讨。特别是对离车站仅为4m左右的中央公寓这一建于解放前的老建筑物,车站在施工前和施工中采取了降水纠偏、树根桩隔断区和跟踪注浆等保护措施。此建筑物虽在车站施工前、中和后有一定的沉降,但由于控制好了它沉降势态,直至车站施工结束,没有发生门、窗无法关启的现象和裂缝,为地铁施工和环境保护提供了一个有益的经验。
This article discusses the construction and management of the construction of the station of Shimen metro line No.2 on the railway station construction and environmental protection. Especially for the central apartment which is only about 4m away from the station, the old building was built before the liberation. Pre-construction and construction stations used such measures as precipitation correction, tree root pile isolation area and tracking grouting. Although this building has certain settlement before and after the construction of the station, due to the well control of its subsidence state until the construction of the station ends, there are no phenomena or cracks that the doors and windows can not be closed and the construction of the subway and environmental protection Provided a useful experience.
