摘要
广西灵山县灵东水库除险加固工程输水隧洞岩性破碎稳定性差,大部分为Ⅳ类围岩,为此,采用一次喷锚支护,二次永久砼衬砌和灌浆处理的施工方法,确保了输水隧洞工程的施工安全和质量。
Lingdong reservoir reinforcement project is located in Lingshan County of Guangxi. Its water conveyance tunnel is accommodated in fractured surrounding rock of Ⅳ category mostly with poor stability. The adopted construction method include applying anchorage shotcrete support first before permanent concrete lining and grouting treatment, ensuring the tunnel construction safety and quality.
