Rock wall crane beam construction is the focus and difficulty of underground powerhouse construction. The quality of its excavation molding will directly affect the operation safety of the plant bridge crane. This article introduces the excavation procedure of rock wall crane beam for the underground powerhouse system engineering of a pumped storage power station And method, anchor rod construction, net hanging, and spraying construction have achieved good results, and have certain reference value for excavation and support construction of rock wall crane beams in similar projects.
