Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and in particular to a reinforcement device for earthquake-resistant steel pipe piles. Background Art

[0002] In construction projects in earthquake-prone areas, earthquake-resistant reinforced pipe piles are needed to ensure the stability of the building. Earthquake-resistant reinforced pipe piles are pile foundation components with earthquake-resistant properties. When building houses, earthquake-resistant reinforced pipe piles are used to support the houses. In order to improve the earthquake resistance of earthquake-resistant reinforced pipe piles, spiral reinforcement devices such as steel end plates and steel cages are needed. When the pipe piles are made, spiral reinforcements, steel end plates and steel cages are installed inside the pipe piles to ensure the earthquake resistance of the pipe piles.

[0003] According to CN201710502859.6, the present invention discloses a pile extraction device and method for reinforced concrete prestressed pipe piles, comprising a pile extraction device body, an anchor head, a second anchor body, and an anchor cable. The pile extraction device body also includes a tension module for applying tension to the anchor cable, and a checkpoint for extracting the pile body. First, a layer of adhesive is applied to the inner wall of the pile bottom. Then, a first anchor body is cast at the bottom of the pile body. The anchor cable and anchor head are placed at the bottom, bonding the anchor head to the first anchor body. The casting pipe is then extended to the bottom of the pile body and a second anchor body is cast on the anchor head. The pile extraction device body is then erected on the ground, and the checkpoint is secured to the pile body. Finally, after the second anchor body and the first anchor body have solidified, a vertical upward tension is simultaneously applied to the anchor cable and the checkpoint. This tension acts simultaneously on the top and bottom of the pile body, thereby smoothly extracting the entire pile body without damaging or breaking the pile body. The present invention also has the advantages of a simple structure and easy operation.

[0004] However, earthquake-resistant reinforced pipe piles generally use steel end plates to improve the strength and rigidity of the pipe pile ends. The steel end plates are generally directly welded to the surface of the pipe pile ends, and the steel end plates are welded to the pipe pile ends in a circle. Since the steel end plates are always exposed to the external environment, they are easily corroded by rainwater, groundwater and corrosive media in the soil for a long time.
