Construction Technology of Reserved Rock Cover Excavation for TB Hydropower Station Main Building
Due to the criss crossing and interlocking arrangement of underground engineering caverns,a multi-dimensional,three-dimensional and parallel construction situation is formed in terms of space and time.Combining some advanced and rapid construction methods for large-scale underground engineering construction,TB Hydropower Station has innovatively proposed a"reserved rock cover method"for excavation construction of underground powerhouses.It solves the problem of parallel construction of the upper and lower levels of underground factory buildings,as well as the problem of long construction period occupied by excavation support due to the large excavation height using conventional construction methods,accelerating the construction progress and shortening the construction period.
