Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, and particularly relates to a high-strength precast pipe pile structure. Background Art

[0002] Precast piles are precast concrete pipe piles or steel pipe piles made in factories or construction sites. Usually, due to production, transportation, and construction reasons, the length of precast concrete pipe piles is limited. Generally, it is not suitable to exceed 15m, and it is difficult to meet the pile length required by the bearing capacity of buildings at one time. Therefore, on-site pile splicing is required during pile driving, that is, the top end of the previously driven pile is connected to the lower end of the next pile.

[0003] The connection of existing precast piles mainly adopts the welding method. However, the welding method will cause welding deformation due to the high temperature at the welding point, resulting in the skew of the pile body and affecting the bearing capacity of the foundation pile. Moreover, the relative positions of the two pipe piles cannot be accurately adjusted before welding, which will further cause the pile body to tilt. Content of the Utility Model
