摘要
文章以一跨线污水管碰接工程为例,简要介绍了小口径PVC塑料管的一种特殊的顶管施工方法———逐步扩孔法。这种施工方法既保证了道路正常交通,又不破坏周围环境,且具有造价低、进度快等特点,亦为顶管施工技术向小口径管的顶进发展作出一成功范例。关键词:顶管施工;PVC塑料管;碰接工程;
This article mainly discusses a special technique of enlarging excavation step by step according to an example of the intersection construction of small-diameter plastic sewage PVC-pipes crossing roads. The technique can not only ensure the regular traffic but also keep the environment intact around the construction site. With its low cost and quick construction the technique is worth diffusion.
