中国专利 ZL92200016. 6公开了一种螺旋成型管的塑料缠绕型材。 该型材 一个侧边沿具有卡肋， 另一个边沿具有卡槽， 在连续缠绕成型时， 两者相互 卡紧而形成螺旋管道。 但存在的问题是： 用这种型材不能制成大管径的管道。 因为该型材的厚度是有限的， 由其构成大管径的管道肯定强度不够； 若重叠 缠绕， 由于层间无法固定， 不能相互固定， 强度仍然无法实现。
中国专利 ZL001330209 公开了一种由塑料型材螺旋缠绕成型的管道。 这 种管道可以通过多层缠绕而构成大口径管道。 但存在的问题是： 多层缠绕所 采用的型材在层间扣合的过程中， 很难扣合到位， 要求缠绕管道的设备结构 复杂， 而且耗材量大， 不能根据所缠绕管道的所需管径大小、 强度大小灵活 的选择型材用量和缠绕方式。
发明内容
本发明的目的在于提供一种能制成大管径的、 可以在现场制作的、 使用 寿命长， 可以根据所缠绕管道的所需管径大小、 强度大小灵活的选择型材用

本发明的上述目的是通过这样的技术方案实现， 即一种型材螺旋缠绕管， 由两种型材连续多层螺旋缠绕而成， 其中型材 A的边沿分别具有 T型肋和 T 型槽， 在 T型肋和 T型槽之间， 具有相间布置的凹槽和凸台， 在管道螺成型 旋缠绕中， 相邻的 T型肋和 T型槽相互嵌合自锁卡紧， 所述凹槽和凸台构成 螺旋凹槽、 螺旋凸台； 其特征是： 以型材 A为螺旋缠绕管的基层， 在其所形 成的螺旋凹槽或 /和凸台上嵌合型材 B， 所述型材 B为上下两端分别具有一个 凸台或凹槽， 或分别具有一个凹槽和一个凸台， 所述型材 B 的凹槽或凸台和 型材 A螺旋缠绕形成的螺旋凸台或螺旋相互槽嵌合锁紧， 构成螺旋管道的至 少一层重叠加强层， 所述重叠加强层上存在可与型材 A或型材 B继续嵌合的 螺旋凹槽和凸台。
对于管径需要更大或需要强度更大的螺旋管道时， 所述型材 B缠绕形成 的层叠加强层表面形成的螺旋凹槽或螺旋凸台上还可以继续与型材 B 的凹槽 或凸台嵌合构成另一层或更多层的重叠加强层。 所述型材 B可以根据管道强 度的需要在所述螺旋凹槽或凸台上相邻缠绕或间隔缠绕。
附图说明
本发明的上述结构可以通过附图给出的实施例进一步说明。
本发明有如下附图：
