随着我国水利水电工程建设的快速发展,隧洞工程逐渐引起人们的关注。为了解决辽宁周边的缺水问题,中南部城市地区兴建了大伙房水库输水工程。大伙房水库输水工程主要是将大伙房水库的水通过隧洞和管道输送到下游受水城市。经大伙房水库调节后,多年平均供水量17.86亿m3。但是,由于隧洞开挖后容易引发地质构造的严重损坏,水工隧道灌浆法可以有效针对其破碎性进行牢固与强化,减少岩石的变形与碎裂,提高岩石的均质性与整体性。而采用回填灌浆法与固结灌浆法能够改善水工隧道施工环境,达到大伙房水库输水工程的要求。
With the rapid development of China’s water conservancy and hydropower projects, the tunnel project has drawn people’s attention. In order to solve the problem of water shortage around Liaoning, the Dahuofang Reservoir Water Conservancy Project has been constructed in central and southern urban areas. Dahuofang reservoir water project is to send the water of Dahuofang Reservoir to the downstream water-receiving cities through tunnels and pipelines. After adjustment by the Dahuofang Reservoir, the average water supply for many years is 1.786 billion m3. However, due to the serious damage of geological structure caused by tunnel excavation, the hydraulic tunnel grouting method can effectively strengthen and strengthen its crushing property, reduce the deformation and fragmentation of the rock, and improve the homogeneity and integrity of the rock. The use of backfill grouting and consolidation grouting method can improve the construction environment of hydraulic tunnel and meet the requirements of Dahuofang reservoir water conveyance project.
