热沥青灌浆工法于地下工程涌水处理的应用

The Application of Hot Bitumen Grouting for Extreme Inflow Treatment in Underground Engineering

热沥青灌浆工法除了应用于隧道内的巨量涌水处理外,在地下建筑结构大量涌水之改善处理工作上,也完成一颇具参考价值的实例。此两件案例的工作条件、涌水行为及施工设备均差异极大,然而在同一工法及材料的操作原理下,均得到了显著的成效。依据此两件特殊工程案例的应用经验,以及沥青浆材的物理特性,总结了沥青灌浆工作的基本操作特性及应用原则,以供其它类似涌水案例之应用参考。

Except the application in the situation of tunnel extreme inflow treatment, there was another successful inflow treatment case completed by Bitumen Grouting in underground building structure. The background of those two projects, including the working condition, inflow characteristics, and the construction facilities, had very explicit difference. However, the effectiveness was achieved by the same grouting method. According to the experiences of these two projects, this paper summarizes some operation principles of bitumen grouting which could be the reference of the other similar inflow treatment cases.
