东伦敦线的延伸
通用的上部结构系统满足隧道、高架桥和小半径弯轨等的不同需求
通过将东伦敦线接入伦敦地上轨道交通网,既有的东伦敦地铁线在两个方向上都得到了延伸和改造。 这条东伦敦地铁线以前无足轻重,而在其接入伦敦地上轨道交通网之后将成为整个地区的中心运输线路。 东伦敦线于 2010 年重新投入使用。
挑战
- 列车线路经过隧道以及带有急转弯的桥梁和高架桥
- 针对不同类型的建筑规划出可以通用的上部结构系统
- 针对列车轨道沿线众多建筑的振动防护
Getzner 解决方案
负责这个项目的规划师决定将轻质质量弹簧系统与单个弹性支撑块相结合。 因此,针对所有建筑类型都能采用合适的上部结构系统。 在包括道岔区域在内的整条板式无砟轨道上采用 LVT («low vibration track») 上部结构系统。
对于要求极高的区域,除了采用 LVT 系统外还会安装带有 Getzner Sylomer® 衬垫的轻质质量弹簧系统。 LVT 系统的通用性明显简化和加快了施工过程。
客户所获得的优势
- 交叉道口内的合适刚度,以及安装了用于隔离板坯的侧面衬垫
- 通用的上部结构系统满足隧道、高架桥和小半径弯轨等的不同需求
- 适用性强的解决方案: LVT 系统和质量弹簧系统相结合
