Description

Technical Field

[0001] The utility model relates to the technical field of concrete pipe piles, in particular to a prestressed concrete pipe pile head core filling structure. Background Art

[0002] Concrete pipe piles serve as the foundation for building a house. When geological conditions are poor and the bearing capacity of the foundation is low, pile foundations are used. Piles are driven into the ground one by one, transferring the weight of the building above to the higher-bearing soil layer below through the pile foundation. These piles can be categorized as post-tensioned prestressed pipe piles or pre-tensioned prestressed pipe piles. Pre-tensioned prestressed pipe piles are hollow, elongated concrete precast components manufactured using a pre-tensioning process and centrifugal forming. They primarily consist of a cylindrical pile body, end plates, and steel sleeves. Prestressed concrete pipe piles are designated PC, prestressed high-strength concrete pipe piles are designated PHC, and thin-walled pipe piles are designated PTC. The concrete strength of PC piles must be no less than C60, the strength grade of thin-walled pipe piles must be no less than C60, and the concrete strength grade of PHC piles must be no less than C80.

[0003] The patent document with publication number CN202323938U discloses a prestressed concrete hollow pipe pile core filling structure, which includes circumferentially uniformly distributed longitudinal reinforcement, spirally arranged stirrups welded outside the circumferentially uniformly distributed longitudinal reinforcement, and support steel plates welded at the bottom ends of the circumferentially uniformly distributed longitudinal reinforcement. The advantage of this utility model is that the core filling steel bars can be used as dowel bars to connect the pipe piles and the foundation pedestal, which not only ensures safety but also facilitates construction, firmly combines the new and old concrete, and compensates for the reduction in shear bearing capacity caused by the loss of prestress when the piles are cut.

[0004] When used, the above application ensures safety and facilitates construction, ensures a firm bond between new and old concrete, and compensates for the reduction in shear bearing capacity caused by the loss of prestressing of the cut piles. However, in actual application, it is inconvenient to adjust and position the pipe piles according to their size, which reduces the ease of use of the structure. Utility Model Content

[0018] In a preferred scheme, the number of the reinforcing ribs is five, and the five reinforcing ribs are equidistantly distributed in a circumferential array on one side of the support plate.

[0019] Through the setting of the reinforcing rib, the effect of matching and coagulation of the concrete in the pipe pile is realized, and the strength of the structure is increased.

[0020] In a preferred scheme, the reinforcing ring is spaced apart from the inner wall of the vertical pipe, and the top of the reinforcing rib is higher than the height of the vertical pipe.

[0021] Through the gap between the vertical pipe and the reinforcing ring, the reinforcing ring can be completely coagulated in the concrete during the subsequent concrete pouring process.

[0022] As can be seen from the above, the prestressed concrete pipe pile head core filling structure has the following technical effects.

[0023] Firstly, through the setting of the core filling assembly, the parts on the surface of the supporting plate can be adjusted according to the size of the pipe pile during use, so that one end of the limiting rod is in contact with the inner wall of the pipe pile, thereby maintaining the firmness of the core filling structure during the core filling process, facilitating adjustment and positioning, and improving the use convenience of the structure.
