Description

Technical Field

[0001] This utility model relates to the field of concrete pipe pile technology, and in particular to a prestressed concrete pipe pile that is easy to connect and fix. Background Technology

[0002] Prestressed concrete pipe piles are slender, tubular members driven into the ground with a cross-sectional dimension much smaller than their length. The upper part of the pipe pile connects to a pile cap (beam) to form a pile foundation. The foundation structure is a prestressed concrete structure, which can be divided into post-tensioned prestressed pipe piles and pre-tensioned prestressed pipe piles. They feature high bearing capacity, good stability, and low settlement, and can be constructed using mechanized methods, greatly improving construction progress.

[0003] Existing prestressed concrete pipe pile connections rely solely on welding or a single mechanical connection. When subjected to hammering or soil compression, these connections generate lateral shear forces, which can lead to loosening and misalignment of the joints, affecting the overall load-bearing capacity. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies and provide a prestressed concrete pipe pile that is easy to connect and fix.

[0005] Therefore, this utility model provides a prestressed concrete pipe pile that is easy to connect and fix, including a first pipe pile, a first annular groove on the outer surface of the first pipe pile, a second pipe pile above the first pipe pile, a second annular groove on the outer surface of the second pipe pile, a sleeve on the outer surface of both the first and second annular grooves, two movable rings slidably installed on the outer surface of the sleeve, four insert plates fixedly connected to the lower surface of the movable rings, first bolt holes on the side walls of the insert plates, four fixing frames fixedly connected to the outer surface of the sleeve, two second bolt holes on the side walls of the fixing frames, four movable grooves on the outer surface of the sleeve, locking pins slidably installed on the inner walls of the movable grooves, and four locking slots on the inner surfaces of both the first and second annular grooves.

[0006] Preferably, the upper surface of the first pipe pile is provided with multiple positioning grooves, and the lower surface of the second pipe pile is fixedly connected with multiple positioning steel bars, which are located in the positioning grooves.

[0007] Preferably, the outer surface of the sleeve is provided with four rotating grooves, and a support member is rotatably installed on the inner wall of the rotating groove.

[0008] Preferably, the upper surface of the support member is in contact with the lower surface of the upper movable ring, and the side wall of the support member is provided with a second actuation groove.

[0009] Preferably, the outer surface of the movable ring is provided with a first actuation groove, and the number of the first actuation groove is four.

[0010] Preferably, the outer surface of the sleeve is provided with four perforated grooves.

[0011] This utility model provides a prestressed concrete pipe pile that is easy to connect and fix, and has the following beneficial effects:

[0012] Compared with existing technologies, this prestressed concrete pipe pile, which is easier to connect and fix, consists of a first annular groove, a second annular groove, a sleeve, a movable ring, an insert plate, a fixing frame, a locking pin, a locking groove, a positioning groove, and positioning reinforcement bars. During installation, the sleeve is first fitted onto the outer surface of the first annular groove, and then the second pipe pile is placed into the sleeve. After aligning the positioning groove and positioning reinforcement bars, the positioning reinforcement bars and positioning groove are welded and fixed using a welding torch. After fixing, the support member is moved so that it retracts into the rotating groove. At this time, the upper and lower movable rings are brought closer together, causing the insert plate to move into the fixing frame. During this process, the arc-shaped surface of the locking pin is squeezed and moved by the insert plate and movable ring, causing the locking pin to enter the locking groove. In this process, the insert plate and the fixing frame are fixed together with bolts through the first and second bolt holes. At this time, the moving ring is completely fixed, and the locking pin is blocked by the moving ring and cannot move. At this time, the locking pin can limit the connection between the first and second pipe piles. Compared with the existing concrete pipe piles, which are only connected by welding or a single mechanical connection, transverse shear force will be generated when subjected to hammering or soil compression. This will cause the joint to loosen and misalign, affecting the overall bearing performance. This prestressed concrete pipe pile, which is easy to connect and fix, uses a sleeve, insert plate bolts for fixing, and locking pins to be inserted into the slot. Multiple structures work together to resist transverse shear force and avoid joint loosening and misalignment. Attached Figure Description
