高架道路桥面排水系统研究

该文通过对桥面横坡低处铺装层内的两种排水通道形式(即碎石盲沟和不锈钢弹簧排水管)的对比试验研究,发现碎石盲沟的排水效果比较好且易于施工、质量容易控制,故推荐桥面横坡低处铺装层内的排水方案采用设置碎石肓沟的形式。此外,还提供了碎石盲沟的施工技术要求,以供工程实践参考。

Study on Drainage System of Elevated Road Deck

Through the comparative tests on two drainage types(spall blind ditch and stainless steel spring sewer)within the paving layer at the lower of cross slope of the bridge deck,the article finds out the drainage effect of the spall blind ditch is better,is easy to construct and its quality is easy to control.Therefore,the article recommends the spall blind ditch within the paving layer at the lower of cross slope of the bridge deck as the drainage scheme.In addition,the article also provides the construction technical requirement of spall blind ditch referred for the engineering practice.
