| 摘 要： | 非开挖施工地下管线有很多工艺方法，这些工艺中存在某些需要改进的地方。并且在适当条件下可以采用新的方法代替现有的方法。第一是非开挖施工“超重地下管道”时，拉管工序中的局部连接新方法的设想。第二是在特殊情况下施工地下电力管线时PE管管节连接方式的选择。第三是在合适的地层中采用“拔管法”更换废旧地下管线的施工工艺。

| Abstract: | Trenchless Technology has many way to construct underground pipeline, but there are some problems in it and must be improved. In addition we can use new methods instead of the existing methods. First is the projection of new local connection way during the drag pipeline working procedure when overweight underground pipeline under No- Dig construction. Second is the selection of PE pipe joint connection way when underground electric power pipeline under construction in extraordinary circumstances. Third is the use of tube drawing in the suitable layer to replace the old pipelines. |
