摘要
随着城市的发展,人们对供水水质和水量及供水可靠性要求逐渐提高,供水管道普及率逐年提升,淡水资源时空分布的不均衡使得沿跨海(江)大桥敷设供水管道已不可避免.城市供水管道跨越江海可采取新建管桥或从河床穿越的方式,但其施工和维修难度大、造价高;同时,管桥还要占用城市空间影响城市景观,而从河床穿越的供水管道则会增加供水水质污染及影响航道通航等风险.因此,以澳氹第四条跨海大桥市政供水管道设计为例,对典型的跨海(江)大桥敷设供水管道的前期方案、设计计算等进行了分析总结,并对其关键技术要点进行了探讨,对其他沿跨海(江)大桥敷设供水管道的工程设计施工等具有较大的指导意义.
Abstract
With the development of the city,the requirements of water quality,quantity and reliability of water sup-ply has gradually improved.The penetration rate of water supply pipeline has increased year by year.The imbalance of the spatial and temporal distribution of fresh water resources makes the laying of water supply pipeline along the cross sea(river)bridge inevitable.That urban water supply pipeline crossing the river and sea can apply building a new pipe bridge or crossing the river bed,but its construction and maintenance are difficult and the cost is high;At the same time,the pipe bridge also occupies the urban space and affects the urban landscape.That water supply pipe crossing the river bed will increase the risk of water quality pollution and affect the navigation channel.Based on the municipal water supply pipeline design for the fourth cross sea bridge in Aodang,Macao as an example,the paper analyzes and summarizes the preliminary scheme and design calculation of the typical cross sea(river)bridge laying water supply pipeline,and discusses the key technical points,which has great engineering guiding signifi-cance for the design and construction of water supply pipeline laying along the cross sea(river)bridge.
