Further, two end faces up and down of described stiffening rib are connected with circular inner tube with described reinforcement steel band by adhering resin layer.And the material of described stiffening rib is plastics, metal or composite material.
Further, in described circular inner tube, can also be provided with reinforced layer, described reinforced layer is along the circumferential direction spiral winding of circular inner tube, and described reinforced layer is connected with described circular inner tube by bonding several resin layers.
Or, in described outer tube, being provided with reinforced layer, described reinforced layer is along the circumferential direction spiral winding of outer tube, and described reinforced layer is connected with described outer tube by adhering resin layer.
Certainly, in described circular inner and outer tubes, be provided with reinforced layer, and described reinforced layer is all along circumferential spiral winding, and by adhering resin layer, is connected with described circular inner tube or outer tube simultaneously.
And described reinforced layer is thread reinforced layer or banded reinforced layer, wherein, described thread reinforced layer is wire, metallic cable, fiber tuft or textile rope; And described banded reinforced layer is fiber band or strengthens cloth.
When being fiber band, the mode of the spiral winding of described banded reinforced layer can be stacked winding.
In actual winding intensifies process, a number of described reinforced layer spiral winding is single head or bull.
Certainly, the rotation direction of described reinforced layer can be wound around for single rotation direction, also can be wound around for double rotational directions.
In addition, the cross section of described stiffening rib is triangle, rectangle, trapezoidal, " I " shape or "T"-shaped.
The invention has the beneficial effects as follows: the present invention by arranging reinforced layer in circular inner tube or outer tube, not only improved ring stiffness grade of the present invention, and strengthened it and born interior pressure energy power, and owing to being provided with stiffening rib between the arcuate inner walls face at steel band and the outer wall of circular inner tube, therefore when enhancing steel band deforms or during spreading, effect due to stiffening rib, can make invention tubing more firm, and the outer bearing capacity original intention of maintenance invention, thereby extend tubing working life, expanded the application area of heavy-calibre spiral corrugated pipe.
