Abstract: |
According to ekou iron mine south west belt transportation tunnel of deformed chlorite pressure, according to the deformed degree of different design with different reinforcement schemes, the long anchor rod, anchor rope, steel arch shelf, spray with network support, as well as the landslides area increase pipe roof design, and construction key points are put forward. According to the design process of the safe operation of the belt tunnel does not appear damage phenomenon. Draw lessons from the experience, promoting chlorite geological conditions in tunnel design and construction attention, and if there is a pressure damage phenomenon, how to take effective reinforcement measures, both to ensure the construction safety, and to achieve reinforcement effect. |
