Application of Early Strength Mortar Prestressed Anchor Rod in Surrounding Rock Support of Underground Powerhouse in Hydropower Station
The underground powerhouse project of a water diversion and power generation system hydropower station is supported by prestressed long anchor rods and anchored with high-strength mortar.It reduces interference with other operations,shortens the support period,quickly and effectively suppresses the deformation of the surrounding rock caused by the excavation of large-span caverns during the construction process,restores the overall stress state of the surrounding rock,improves the overall stability of the caverns after excavation,and effectively ensures construction safety and operation period.
