Abstract:

 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.

Key words: extreme inflow treatment  , hot bitumen grouting  , grouting  , fracture.
