Abstract: Rotary excavated bored cast-in-place piles have the characteristics of high construction efficiency, large hole depth, and strong adaptability. Therefore, they are widely used in the construction of the basic branch of construction engineering. More difficult. This paper analyzes the application process of rotary excavation pile construction in a shed remodeling project in Kunming undertaken by this unit, and analyzes the application process of rotary excavation pile construction technology in karst strong development sites, in order to provide reference and reference for peers.
