Excavation Construction Technology of Rock Anchor Beam in Underground Powerhouse
The excavation construction of the underground powerhouse of the hydropower station mainly includes arch excavation,rock anchor beam excavation,and high side wall excavation.The construction of rock anchor beams is a key and difficult point in the entire underground powerhouse construction process,with high excavation quality requirements and meticulous construction.The excavation construction quality and refinement level of rock anchor beams can reflect the excavation construction level of the entire underground powerhouse.Especially in the construction of rock anchor beams under adverse geological conditions,the excavation construction technology is particularly critical.Based on engineering examples,this paper analyzes and summarizes the excavation construction technology of rock anchor beams.
