Construction Characteristics and Quality Control Points of Punched Cast-in-place Piles in Karst Areas
Punched cast-in-place pile is a common foundation pit support and foundation treatment technology,which is widely used in buildings,bridges,tunnels,docks and other civil engineering.The punched cast-in-place pile forms a solid pile body by pouring reinforced concrete into the foundation trench through rubber pipes,which plays the role of supporting and reinforcing the soil.As an effective foundation treatment and foundation pit support technology,the construction process of punched cast-in-place piles needs to be carried out in strict accordance with design requirements and construction specifications to ensure the quality of the pile body and the safety of the overall engineering.Based on the actual case,this paper mainly discusses the construction characteristics and quality control points of punched cast-in-place pile in karst areas,aiming to provide reference for the development of similar engineering projects.
