Description

concrete pile

technical field

Background technique

Concrete piles are piles made of concrete, including ordinary reinforced concrete and prestressed concrete. It has the advantages of saving wood and steel, durable, and low cost. It has been widely used in the foundation engineering of hydraulic construction, industrial construction, civil construction and bridges. At present, the connection between concrete piles and cap foundations, columns, and beams generally adopts the method of inserting the inner cavity of the concrete pile into the steel skeleton cage and then filling the core with concrete. Since the inner wall of the concrete pile is relatively smooth, the bond strength between the cored concrete and the inner wall If it is poor, it is easy to pull out the reinforced concrete core, which will cause the concrete pile to separate from the cap foundation, column, and beam, thereby causing engineering quality and safety accidents, resulting in huge life safety and property losses.
