Abstract :
Crane-beam on rock wall is an integrated construction technology containing smooth presplit blasting, anchor technique, concrete technology, stress, strain and displacement measurement technology. Crane-beam on rock wall is a key project in underground powerhouse engineering and is well worth discussing in effective economical construction. In this paper, excavation of crane-beam on rock wall and concrete construction had been introduced in detail on power generation systems in underground powerhouse of Longtan Hydropower Station. Crane-beam on rock wall contains a number of steel and has a complex geological conditions, complex steel structure, high technical requirement and difficult construction. Correct construction procedure and technology is the key to ensure quality of construction.
