High-strength corrugated pipe for prestressed concrete
The invention relates to a high-strength corrugated pipe for prestressed concrete. The high-strength corrugated pipe comprises a plastic inner pipe, a supporting belt and a steel-plastic composite belt, wherein the supporting belt is spirally wound on the plastic inner pipe; the steel-plastic composite belt wraps the supporting belt and the plastic inner pipe; and the supporting belt comprises a top corner strip fixed on the inner wall of the steel-plastic composite belt, a pair of bottom corner strips wound on the plastic inner pipe, and steel bars fixed on the top corner strip and the pair of bottom corner strips, and the steel bars are formed by bending the top corner strip and the bottom corner strips for multiple times. The mode that the plastic inner pipe is combined with the steel-plastic composite belt is adopted, the supporting belt with the optimized structure is used for filling and supporting in the steel-plastic composite belt, the corrugated hardness and the contact area are enhanced, meanwhile, the bonding strength between the installed corrugated pipe and concrete can be improved, the rigidity of the corrugated pipe can be integrally enhanced, and the use requirements in the concrete capital construction fields of bridges, large-span buildings and the like can be met.
本发明涉及一种预应力混凝土用高强度波纹管，其包括塑料内管、螺旋缠绕于所述塑料内管上的支撑带、包裹于所述支撑带和塑料内管上的钢塑复合带；所述支撑带包括固定于所述钢塑复合带内壁的顶角条和一对绕设于所述塑料内管上的底角条、固定于所述顶角条和这对底角条上的钢条，所述钢条在所述底角条和顶角条之间经过多次弯折而成。本发明采用塑料内管结合钢塑复合带的方式，并通过结构优化后的支撑带在其中进行填充支撑，在加强波纹硬度和接触面积的同时，能提高波纹管安装后与混凝土之间的粘结强度，并能整体增强波纹管的刚度，可满足桥梁、大跨距建筑等混凝土基建领域的使用要求。
