白云桥大修 完工通车
2017-08-22 14:46:50 中国青年网
本报讯(记者孟环)昨日记者从北京市城市道路养护管理中心获悉,经过两天不断交施工,昨天白云路白云桥大修工程顺利完工通车。
据悉,白云桥位于北京市白玉路上,跨永定河引水渠,1996年修建,至今已使用20年。桥梁总宽41.7米,面积1966平方米。此次大修主要包括桥面系维修、裂缝封闭、更换伸缩缝橡胶带等内容。
为适应白云桥桥面交通流量较大、夜间施工时间较短的特点,在桥面防水关键环节,工程采用了SBS聚合物改性沥青纤维碎石桥面防水技术,不仅方便快捷,而且还较好地解决了涂料类防水材料在沥青摊铺及路用过程的难题,同时增强了桥梁防水性能。
此外,8月21日夜间,位于北京市朝阳区新东路中段的新东路桥大修工程也进入防水层施工环节,预计11月完工。J147
