位于法国格勒诺布尔中心的结构噪音长期防护
轨道振动引入长期防护
为保护城市环境不受有轨电车通行所造成的振动的影响,格勒诺布尔在城市中心采用了的质点弹簧系统。有些区段已采用格士纳 Sylomer® 解决方案实现隔离 30 余年,且无需任何维护。格士纳在 2004 年投入运营的瓦尔米大街区段上进行该系统长期性能的调研。
挑战
- 轨道振动引入长期防护
- 47 公里长且设有 81 站的有轨电车网络
- 弹簧质点系统长期保持高效性能
- 63 Hz 条件下隔离性能至少可达 20 dB
- 格勒诺布尔苛刻的运行条件加之该系统的高强度使用
格士纳解决方案
为保护周边建筑免受振动影响,这里装设了一套格士纳 Sylomer® LG28 质点弹簧系统。运行 15 年后,位于瓦尔米大街的这套格士纳解决方案的长期性能通过一系列测试显现出来。
客户优势
- 针对结构噪音隔离的理想个性化解决方案
- 运行 15 年仍不失其高性能
- 弹性可靠、持久且免维护
尽管格勒诺布尔运行条件苛刻,而且该系统又是高强度使用,但格士纳解决方案如今的隔振效力仍一如最初。有鉴于此,我们可以放心地进行中心轨道的计划调整。
