Abstract:

If water gushing happens in inclined shafts with railbound transportation system, disastrous results may occur due to the difficult construction conditions such as the steep slopes and the water pumping difficulties. Taking No.4 inclined shaft of Xiangshan tunnel as an example, the author, on basis of introducing the shaft flooding process and analyzing the causes for the flooding, studies on the water pump scheme, the method of water sealing on the working face and water seepage treatment in the excavated section and puts forward some helpful suggestions on minimizing the water gushing risks in inclined shafts with railbound transportation system.
