在城市建设过程中,不可避免要对城市管道及管线进行改造。当前大多城市的地下管线众多且复杂,相关的竣工资料不齐全、不规范或缺失,给开挖施工造成很大的困难,顶管施工技术在很大程度上解决了这一难题。文章结合给排水工程实例,对顶管技术进行分析,总结出适合于实际施工的方法。 In the process of urban construction, urban pipelines and pipelines will inevitably be transformed. At present, most of the underground pipelines in most cities are numerous and complicated, and the relevant completion materials are incomplete, irregular or missing, which cause great difficulties in excavation construction. The pipe jacking construction technology largely solves this problem. Combined with water supply and drainage engineering examples, the article analyzes the pipe jacking technology and sums up the methods suitable for practical construction.
