Abstract:

Sailimu lake tunnel is located at the bank of Sailimu Lake in Yili, Xinjiang, which has special geographical environment (such as extreme coldness and severe freezing and thawing) and complex hydrology conditions. The author investigates into the causes for the large amount of water inflow, then sets down comprehensive treatment measures combining grouting and water sealing with pumping and drainage. In the practice, he explores how to enhance the pumping and drainage efficiency with reasonable machines. Moreover, he compares grouting and water sealing materials of variable mixing ratio to affirm the most favorable materials and mixing ratios. With above measures, the treatment of the water gushing in Sailimu lake tunnel is perfect.
