The utility model discloses a high strength hollow circular steel skeleton winding pipe, comprising a pipe body and a steel frame adopts a hollow circular tube made of steel skeleton, spirally wound around the periphery of the pipe body wall, and the steel skeleton are arranged on the peripheral wall of the pipe body and weld for anti-corrosion coating development, steel the skeleton and the pipe body is arranged coaxially with strengthening pipe body, strengthening pipe melt and anti-corrosion coating is connected. The utility model has the advantages of high strength hollow circular steel skeleton winding hollow by cross section is a hollow round steel frame, can effectively improve the mechanical properties, and forming of the steel frame is no longer constrained by the existing molding technology, enhanced pipe diameter can do more, because the cross section of the steel skeleton were round. The connection between it and the anti-corrosion coating and the pipe body more firmly, and by setting the strengthening pipe body can play to enhance the connection strength and thickness of steel skeleton pipe, steel skeleton is not due to creep by force and loose, use safer, longer life.
【技术实现步骤摘要】
本技术涉及一种波纹管,具体的为一种高强度空心圆形钢骨架缠绕中空管。
技术介绍
现有的钢骨架螺旋缠绕波纹管结构形式单一,如公开号为CN 202228805U的中国专利公开了一种钢带增强聚乙烯螺旋波纹管,该钢带增强聚乙烯螺旋波纹管包括螺旋状的中空管材本体,所述的中空管材本体由聚乙烯表层和聚乙烯内层构成,中空管材本体表面设置间隔螺旋凸起,所述的螺旋凸起为四层结构。该钢带增强聚乙烯螺旋波纹管的四层结构分别为聚乙烯表层、钢带层、粘接树脂层I和聚乙烯内层,螺旋缠绕在中空管材本体上的钢带层的横截面呈“ Ω ”形,其两侧由聚乙烯表层和聚乙烯内层粘接固定,采用该结构的钢带层虽然在一定程度上能够增强波纹管的强度,但是还存在以下缺陷:1、由于波纹管一般深埋于地下使用,其不仅会受到压力作用,而且还由于地质结构变化,会受到扭转力;然而,现有波纹管的钢带层的横截面呈“ Ω ”形,在埋地波纹管长期受到蠕动力的情况下,以及“ Ω ”形钢带在成型时聚集的内应力,易使其两侧与聚乙烯表层和聚乙烯内层之间的粘接会松动,甚至脱落,导致波纹管的环刚度被破坏,减少使用寿命,甚至造成工程质量事故;2、由于现有 ...
