| 摘 要： | 铺设地下管线大都采用开挖路面的方法,这样做的结果是破坏了街路的完整性,影响交通与城市面貌,采用“非开挖地下管线铺设方法”施工可以避免为铺设地下管线而开挖街路。损伤路面、影响交通。它包括以下三种方法：挤密导孔－拉削扩孔方法,小断面挖掘液面送管方法,地下夯管方法。

| Abstract: | The way to lay underground pipelines of excavating streets often be used.But that would destroy the integration of streets, and impair the traffic and the outlook of cites. Using "the ways of non-excavating streets to lay underground pipelines" can avoid digging streets. When laying underground pipelines, the streets can't be destroyed and thetraffic can't be impaited. The first way is that, the soi1 were pressing a guide hole, thenusing broach to extend the hole. The second way is digging a tunnel, then pushing the un-derground pipe into it by the hydraulic pressure. The third way is the underground ram-ming pipe. They form the ways. |
