Embodiment 1
[0035] Such as figure 1 , figure 2 , a composite tubular concrete composite structure, comprising 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 in the interior of the steel pipe 2, and the transverse prestressed steel wire 3 and the fiber reinforced plastic 4 are each one layer.
Embodiment 2
[0037] Such as image 3 , Figure 4 , a composite tubular concrete composite structure, comprising internal concrete 1, steel pipes 2, transverse prestressed steel wires 3, fiber reinforced plastics 4, and longitudinal steel wires 5; wherein, the transverse prestressed steel wires 3 are wound horizontally and uniformly by applying prestress to the steel wires 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, and the internal concrete 1 is filled in the interior of the steel pipe 2, and the transverse prestressed steel wire 3 and the fiber reinforced plastic 4 are each one layer. At the same time, a layer of longitudinal steel wires 5 is arranged between the transverse prestressed steel wires 3 and the steel pipe 2. During specific implementation, the longitudinal steel wires 5 are evenly arranged around the steel pipe 2 along the axial direction of the steel pipe 2, and are temporari...
Embodiment 3
[0039] Such as Figure 5 , Figure 6 , a composite tubular concrete composite structure, comprising internal concrete 1, steel pipes 2, transverse prestressed steel wires 3, fiber reinforced plastics 4, and longitudinal steel wires 5; wherein, the transverse prestressed steel wires 3 are wound horizontally and uniformly by applying prestress to the steel wires 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, and the internal concrete 1 is filled in the interior of the steel pipe 2. The transverse prestressed steel wire 3 has two layers, and the winding distances of the two layers are different. The fiber reinforced plastic 4 is 1 layer. At the same time, between the transverse prestressing steel wire 3 and the steel pipe 2 and between the two layers of transverse prestressing steel wire 3, a layer of longitudinal steel wire 5 is respectively arranged. During specific implementation...
