卵砾层中非开挖铺管技术浅谈

Discuss the trenchless technology for crossing the screes and gravels

非开挖施工技术是一种不进行地面开挖而进行地下铺设的工程,但对于穿越卵砾层等复杂地层具有一定的限制性。因此如何使穿越铺管的轨迹避开地下的复杂管网及成功穿越复杂地层成为非开挖铺管技术研究的面临的关键问题。本文探讨了在复杂地层(卵砾层)中导向孔的施工工艺及泥浆的配置,为非开挖技术在卵砾层中穿越铺管的应用开辟了新的思路。

Trechless is a technology which can pave underground pipelines in No - dig. But ,there are some difficult to crossing the screes and gravels. Therefore,how to shun paved pipelines and crossing a complex stratum become a key. This paper discuss construction crafts and slurry configuring. Besides, there are some creation of crossing the screes and gravels for paveing underground pipelines.
