锦屏电站引水隧道纳米仿纤维混凝土防岩爆应用技术研究

Nano Fiber Reinforced Concrete Anti-Rock-Burst Application Technology in Diversion Tunnel of Jinping Power Station

从加快混凝土的凝结时间、一次喷射厚度、提高混凝土的抗压强度、与围岩的粘结强度等出发,运用多种试验方法并对施工工艺进行对比,采用水涨式锚杆及涨壳式锚杆外加钢筋网喷射纳米钢纤维混凝土施工工艺,为度过岩爆区提供了技术支持。

To speed up the concrete the setting time,improve jet thickness,the concrete compressive strength,and the bonding strength of surrounding rock,etc.a variety of multiple comparison test method are used and compared to summ up the construction process,the use of water swelling anchor bolt and shell bolt plus jet nano steel fiber reinforced concrete network construction technology to provide technical support to move through the rock blasting area.
