As preferably, also be provided with cross rib on the inwall of described composite material internal mold pipe.
As preferably, described vertical rib is vertical, the cross rib horizontal arrangement, and perhaps cross rib is in tilted layout, and horizontal sextant angle is 15 °~45 °.
As preferably, described cross rib spacing is 10cm~20cm, and width is not less than 3cm, highly is not less than 3mm.
As preferably, the material of described composite material internal mold pipe be single, in length and breadth to fiber than 1:1, the carbon fiber of 1:2 or 1:4, glass fiber, basalt fibre or aryl fiber cloth, or different cloth is alternately laid; Resin used is unsaturated polyphenyl resin, polyethylene or epoxy resin.
As preferably, on described composite material internal mold circular tube external wall, unidirectional or two-way winding at a certain angle forms the Filament Wound Composite pipe through the fibre that resin infiltrates.
As preferably, the built-in steel pipe of described Filament Wound Composite pipe forms composite material-concrete-steel pipe sandwich pile tube.
As preferably, the built-in shaped steel of described Filament Wound Composite pipe forms composite material-steel reinforced concrete pile tube.
Beneficial effect: (1) the utility model has solved existing composite material tube and concrete interface adhesion problem, adopts the industrialization process moulding, forms the reinforced tube of longitudinal and transverse rib and tube wall one, and structural integrity is good, and internal-rib is not easy to come off;
(2) internal-rib flexible design is all easily realized according to the longitudinal and transverse rib that concrete force request is arranged;
(3) composite material tube useful as concrete with ribbing or the prestressed concrete permanent template of building, the layer of putting more energy into has increased composite material and concrete adhesion strength;
(4) round steel pipe or shaped steel be can place in composite material with ribbing, composite material with ribbing-steel tube-concrete pile tube or composite material with ribbing-steel reinforced concrete pile tube formed;
(5) composite material tube tensile strength with ribbing high, from heavy and light, good corrosion resistance, humidity, can protect concrete and steel to avoid the erosion of corrosive deposit, improve the application life of structure, also can be used for the reinforcing of old pier stud;
(6) composite material tube with ribbing can obviously be improved the ductility of performance of concrete column confined, because composite material all is in elastic state before destruction always, especially fiber can not produce permanent set and accumulation destruction under the course under cyclic loading of earthquake, and the pier stud strength degradation is few;
