Pre-consolidation Grouting on Top Surrounding Rock of Underground Powerhouse in Liyang Pumped-storage Power Station
摘要
Abstract
The occurrence of surrounding rocks of underground powerhouse in Liyang Pumped —storage Power Station has significant different and the geological condition is more complex. In order to ensure excavation quality and security of powerhouse crown arch, the rock in the area above powerhouse's arch is grouted for consolidation before the excavation of powerhouse. The pre-consolidation grouting holes are dilled by using down-the-hole drill and enclosed when grouting. The tests show that the effect of pre-consolidation grouting is better and the conditions of surrounding rocks are improved. The pre-consolidation grouting ensures the quality and security of powerhouse excavation.关键词
