据不完全统计,上海市区内大小塞路平均每年因地下管线的敷设、养护、扩容而遭到1000多次“开膛破肚”,这给居民日常生活带来诸多不便。曾有人突发奇想:能不年给道路加条“拉链”?不久这将成为现实。浦东今年建设的“五路一桥”中的张扬路就采用了共同沟的施工方法,把电力电缆、通讯电缆、煤气、自来水等四大管线集于共同沟内埋于人行道下,这在全国尚属首例。 According to incomplete statistics, the average size of roads in Shanghai downtown has received more than 1,000 “openings” each year due to the laying, maintenance, and expansion of underground pipelines, which has caused many inconveniences to the daily lives of residents. There have been whimpers: Can we not add “ziplines” to our roads? It will soon become a reality. Puyang’s Zhangyang Road in the “Five Roads and One Bridge” built this year uses a common trench construction method. The four major pipelines for power cables, communication cables, gas, and tap water are collected in a common trench and buried under the sidewalks. This is the first case.
