Discussion on reinforcement design and construction technology of Beitan Reservoir
Beitan Reservoir has been put into operation for more than 60 years and has problems such as serious seepage in the dam body and foundation,poor foundation condition of the spillway,and plugging of the water con-veyance tunnel.An introduction was made on the key points of the design of dam seepage prevention,reinforcement of spillway and water release facilities.Emphasis was placed on the application of high-pressure rotary jet grouting for anti-seepage treatment of dam body,consolidation grouting for plugging of old culvert,and backfill grouting for the 120°range of the original water release tunnel roof.
