摘要
文章分析中国新加坡工业园区启动区过路输水钢管爆裂原因，后由苏州工业园区开发有限公司提出整改方案，采用球墨铸铁管代替原钢管。因球墨铸铁管强度高，延伸率高，耐腐蚀，是安全可靠用于供水的最佳选择.施工时，从确定地下管线位置、路面开挖、切管、换管、沟槽回填等几方面进行。实践证明，该方案可行可靠。
This paper analyses the causes of water supply pipes burst under the roads in Suzhou Sino-Singapore Industrial Park and puts forward appropriate modification programs.Ductile iron pipes replace the original steel pipes because they have positive properties of high strength, high elongation and corrosion-resistance. It's the optimal choice to convey water through ductile iron pipes, safe and reliable. In the process of construction, locating underground pipes, excavating road surface, cutting pipes, changing pipes, backfilling are carried out. Practice proves the programs are practical and reliable.
