慕尼黑嘉斯台爱乐大厅有效期长达 30 年的隔振措施
道砟垫的稳定高性能——即使在极端条件下
慕尼黑的嘉斯台 (“Am Gasteig”) 文化中心紧邻慕尼黑轻轨的隧道中心: 爱乐厅和市图书馆也位于文化中心内。 该段铁路是标准的木枕碎石上部结构,是德国最繁忙的轻轨路线之一。
挑战
- 针对“噪音敏感型”音乐厅的防振
- 每天的负荷大约为 150,000 吨
- 不同的环境影响
Getzner 解决方案
为了使音乐厅能够用于音乐录制,承建方在 1983 年修建文化中心时便必须考虑到,列车通行时给音乐厅带来的噪声不能超过规定的极限值,即 25 分贝。
为避免噪音敏感型的文化中心中出现结构噪音,1983 年,Getzner 为此生产了 345 米长的道砟垫。
三次测量,同一个结果
2013 年起,我们对 Getzner 道砟垫的长期使用效果有了更进一步的认识: 30 余年来,此产品一直都用于减弱重要铁路段的振动,从而降低其维护成本和维修成本。 道砟垫在轻轨列车驶过时可成功将结构噪音降至最低程度,至今仍发挥着功效。
«所有测试都表明,我们的道砟垫至少还能再使用 30 年。 如果铁轨的使用寿命通常算作 50 年,那么就可以确定,我们的道砟垫能够在铁轨的整个使用过程中都发挥其效用,»Getzner 产品经理 Mirko Dold 介绍道。
即使是在极端条件下,Getzner 道砟垫也能保证其特性和功能性。 即使环境条件不佳(如存在死水),也不会使道砟垫产生任何损坏。
