Embodiment 1

[0029] like figure 1 It is a combined splicing pipe pile of the present invention, which includes two sequentially connected TSC pipe piles 10 and a steel cylinder 20;

[0030] The steel cylinder 20 is a hollow cylinder, which is arranged on the outer side of the junction of two adjacent TSC pipe piles 10 of the combined splicing pipe pile. The steel cylinder 20 is provided with several rows of circular plug welding holes 21 along the circumference, and two adjacent The plug welding holes 21 of the row are set in a staggered manner, and the steel cylinder 20 is welded to the TSC pipe pile 10 through the plug welding holes 21;

[0031] The joint of two adjacent TSC pipe piles 10 is set in the middle of the steel cylinder.

[0032] The preparation steps are as follows:

[0033] (1) Prepare two TSC pipe piles 10 and steel cylinder 20;

[0034] (2) Put one end of the steel cylinder 20 up along the end of one of the TSC pipe piles 10 until the end of the TSC pipe pile 10 reaches...

Embodiment 2

[0038] like figure 1 It is the combined splicing pipe pile of the present invention, which includes two sequentially connected PHC pipe piles 30, YTSC40 and a steel cylinder sleeved on the outer periphery of the connection between the PHC pipe pile 30 and the YTSC pipe pile 40;

[0039] The connection between the PHC pipe pile 30 and the YTSC pipe pile 40 is set in the middle of the steel cylinder 50, and the middle of the steel cylinder 50 is distributed along the circumferential direction with a row of strip-shaped plug welding holes 51 arranged parallel to the pile axis. The plug welding hole 51 straddles the connecting seam between the PHC pipe pile 30 and the YTSC pipe pile 40;

[0040] The YTSC pipe pile 40 includes a pile body 41 and a telescopic sleeve 42 arranged at the connection end of the YTSC pipe pile 40 and the PHC pipe pile 30. The length of the telescopic sleeve 42 is equal to or less than 1 / 2 of the height of the steel cylinder body 50. The telescopic sleeve ...

Abstract

The invention discloses a combined splicing pipe pile, which includes at least two hollow piles connected in sequence, and its innovation point is that it also includes at least one steel cylinder, which is hollow cylindrical and is sleeved on the combined splicing pipe pile. On the periphery of the connection between two adjacent hollow piles, several plug welding holes are arranged on the steel cylinder, and the steel cylinder is welded to the hollow pile through the plug welding holes. The inner wall of the steel cylinder is first welded to the tail of one pile, and then welded to the pile head of the other pile by plug welding. The hydraulic pile connecting pile of the present invention is easy to operate, has high bearing capacity and strong bending resistance; by adding a steel cylinder at the joint of two pile bodies, the bearing capacity of the hydraulic pile is increased; the steel cylinder is provided with The plug welding hole is welded and connected by plug welding, which is convenient for welding and saves time and effort.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a combined splicing pipe pile, and also relates to a pile connecting method of the combined splicing pipe pile. Background technique [0002] With the development of concrete technology, the technology of concrete pipe piles is becoming more and more mature. In addition to being used in industrial and civil buildings, it is also widely used in various fields such as bridges, ports, railways or water conservancy projects. Pipe piles include prestressed concrete pipe piles (PC pipe piles), prestressed concrete thin-walled pipe piles (PTC pipe piles), prestressed high-strength concrete pipe piles (PHC pipe piles), thin-walled steel pipe centrifugal concrete pipe piles (TSC pipe piles) ) and prestressed concrete steel pipe piles (YTSC pipe piles). [0003] PS steel pipe pile is also a kind of pile foundation material that has developed rapidly in recent years....
