Abstract: Prestressed concrete pipe piles used as anti-pulling piles are widely used in building foundation engineering with good quality of uplift, crack resistance, low construction cost, short construction period and many other advantages. A brief description of the pile cap connection with the pipe pile and existing problems were given. Combining with the actual situation of the project site, three connection modes were improved. It is effective to solve the problems caused by the pipe which used as an anti-pulling pile connection with cap.lt makes the building foundation more secure and stable.
Keywords: prestressed concrete pipe pile; anti-pulling; cap; connection
