Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated pile preparation, in particular to a prestressed corrugated pile structure used in water conservancy projects. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits.

[0009] Furthermore, the steel cage includes a plurality of longitudinal steel bars distributed along the shape of the pile body and stirrups wrapped around the longitudinal steel bars; the longitudinal steel bars are a mixed reinforcement structure of prestressed steel bars and non-prestressed steel bars.

[0010] The use of mixed reinforcement of prestressed steel bars and non-prestressed steel bars can increase the prestressed piles' resistance to horizontal impact and improve their ability to resist wave impact.

[0011] Furthermore, the plug-in tenon comprises a plug-in block 1 with a rectangular cross section and a plug-in block 2 with a circular cross section and arranged on a side of the plug-in block 1 away from the pile body; the structure of the plug-in groove is adapted to the plug-in tenon.

[0013] The fixing plate can be better buckled with the connecting block through the cooperation of the convex edge and the convex groove, and a waterproof coating and a water stop strip are provided to further improve the anti-water seepage capability.

[0014] Furthermore, the convex groove is located on the inner side of the insertion hole, and the insertion hole is close to the edge of the fixing plate.

[0015] Furthermore, a water-stopping adhesive layer that swells when exposed to water is provided at the joints between the connecting block and the fixing plate to improve the sealing performance and the anti-seepage capability.

[0016] Furthermore, the pile body, the end plate and the fixing clamp are all coated with an anti-corrosion coating to improve the overall corrosion resistance.
