Prestressed concrete pipe pile butt joint construction member and prestressed concrete pipe pile

Abstract

The invention relates to a prestressed concrete pipe pile butt joint construction member and a prestressed concrete pipe pile, wherein the prestressed concrete pipe pile butt joint construction member and the prestressed concrete pipe pile are capable of ensuring small stress transfer after the prestressed concrete pipe pile and the prestressed concrete pipe pile are butt jointed, and capable of preventing the phenomenon of plate-rotting of an end plate of the prestressed concrete pipe pile. The prestressed concrete pipe pile comprises a prestressed concrete pipe pile butt-joint end plate which is composed of a boss-shaped flange end plate, a circular groove-shaped clamping end plate, two semi-circular boss locking rings and bolts. The end face of the boss-shaped flange en plate is matched with the end face of the circular groove-shaped clamping end plate, bosses inside the two semi-circular boss locking rings are inserted into the circular groove-shaped clamping end plate and the periphery of the boss-shaped flange end plate are connected with bolt screw thread holes of the protruding column inside the two semi-circular boss locking rings through a plurality of bolts. The prestressed concrete pipe pile butt joint construction member and the prestressed concrete pipe pile have the advantages of solving the phenomenon of plate-rotting after the welding of the prestressed concrete pipe pile end plates, and ensuring reliable transfer and reliable butt joint of prestress between an upper segment of the pipe pile and the lower segment of the pipe pile.

Description

Technical field [0001] The invention relates to a pre-stressed concrete pipe pile butt joint that can ensure the butt joint between the pre-stressed concrete pipe pile and the pre-stressed concrete pipe pile, can ensure small stress transmission, and can avoid the phenomenon of rotten slabs at the end of the pre-stressed concrete pipe pile Components and prestressed concrete pipe piles belong to the field of prestressed concrete pipe pile end plates and prestressed concrete pipe pile manufacturing. Background technique [0002] CN201276702Y, the name "prefabricated prestressed concrete pipe pile connecting pile structure", includes lower section piles and upper section piles. The ends of the lower section piles and the upper section piles are pile end plates with a number of self-retaining holes, which are characterized by , It also includes pins corresponding to the number of reserved holes, and the pins are inserted into the reserved holes of the lower section pile and the uppe...

AI Technical Summary

Problems solved by technology

Its shortcomings: due to the surface contact between the upper section pile and the lower section pile, the pin inserted into the self-retained hole of the upper section pile and the lower section pile cannot form a concentrated force at the pin head under the action of the upper section pile. point, the head cannot be produced, that is, the purpose of riveting the upper section pile and the lower section pile pin by the pin cannot be realized; secondly, the end plate is still welded by electric welding, which still causes the occurrence of the phenomenon of rotten plate at the end plate of the welding part, resulting in the occurrence of the upper section pile The quality of butt joint between the pile and the lower section pile is poor, which directly affects the reliability of the pile foundation
