Example Embodiment
[0034] Example one:
[0035] Such as figure 1 , figure 2 , A composite pipe concrete composite structure, including internal concrete 1, steel pipe 2, transverse prestressed steel wire 3, and fiber reinforced plastic 4; wherein the transverse prestressed steel wire 3 is continuously and uniformly wound on the outer wall of the steel pipe 2 by applying prestress to the steel wire. , The fiber reinforced plastic 4 is pasted on the outer surface of the transverse prestressed steel wire 3, the internal concrete 1 is filled inside the steel pipe 2, and the transverse prestressed steel wire 3 and the fiber reinforced plastic 4 are each in one layer.
Example Embodiment
[0036] Embodiment two:
[0037] Such as image 3 , Figure 4 , A composite pipe-concrete composite structure, including internal concrete 1, steel pipe 2, transverse prestressed steel wire 3, fiber reinforced plastic 4, longitudinal steel wire 5; wherein the transverse prestressed steel wire 3 is continuously and uniformly wound in the transverse direction by applying prestress to the steel wire On the outer wall of the steel pipe 2, the fiber reinforced plastic 4 is pasted on the outer surface of the transverse prestressed steel wire 3, the internal concrete 1 is filled inside the steel pipe 2, and the transverse prestressed steel wire 3 and the fiber reinforced plastic 4 are each in one layer. At the same time, a layer of longitudinal steel wires 5 is arranged between the transverse prestressed steel wire 3 and the steel pipe 2. In the actual implementation, the longitudinal steel wires 5 are evenly arranged along the circumference of the steel pipe 2 along the axial direction of t
Example Embodiment
[0038] Embodiment three:
[0039] Such as Figure 5 , Image 6 , A composite pipe-concrete composite structure, including internal concrete 1, steel pipe 2, transverse prestressed steel wire 3, fiber reinforced plastic 4, longitudinal steel wire 5; wherein the transverse prestressed steel wire 3 is continuously and uniformly wound in the transverse direction by applying prestress to the steel wire The outer wall of the steel pipe 2, the fiber reinforced plastic 4 is pasted on the outer surface of the transverse prestressed steel wire 3, and the internal concrete 1 is filled inside the steel pipe 2. The transverse prestressed steel wire 3 has two layers, and the winding spacing of the two layers is different. The fiber reinforced plastic 4 is 1 floor. At the same time, a layer of longitudinal steel wire 5 is set between the transverse prestressed steel wire 3 and the steel pipe 2 and between the two layers of transverse prestressed steel wire 3. In specific implementation, the longit
