摘要
与开挖技术相比,拉管技术具有施工速度快、成本低、不破坏现有路面等优点。特别是在开挖施工无法进行或不允许开挖施工的场合,可用拉管技术从其下方穿越铺设。
Compared with the excavation technology,the tubular technology has the advantages of fast construction,low cost,not destroying the existing roads and so on.Especially when the excavation can not be made or is not allowed to make,the tubular technology can be applied to pass through the pipes from the bottom.
