Abstract

本实用新型公开了一种双壁波纹管,包括内层直管和固定贴合于直管外表面的外层波纹管,所述双壁波纹管的一端为扩口的承口,与所述承口相对的一端为平直段的插口。本实用新型通过将插口端部分加工成平直段,增加了内层直管与外层波纹管在插口端的双壁接触面积,从而增加了管材双壁的粘合强度,使双壁的粘合更稳定,管材在安装时更加顺畅,不会受外力影响而使管材插口端的双壁粘合部分分开,从而保证了安装的质量。

Description

双壁波纹管
技术领域
[0001] 本实用新型涉及ー种地下通信管道用塑料管,更具体地说,尤其涉及ー种双壁波纹管。
背景技术
[0002] 现有双壁波纹管的一端为扩ロ的承ロ,另一端为带有波纹的插ロ,通常是采用承插式的连接方式进行安装。在管材安装的过程中,由于管材的插ロ端是波纹状的,无倒角, 导致安装不顺畅,受外力影响容易使管材双壁粘合部分分开,从而影响管材的安装质量。
实用新型内容
[0003] 本实用新型的目的在于针对上述现有技术的不足,提供ー种安装顺畅、质量可靠的双壁波纹管。
[0004] 为实现上述目的,本实用新型所提供的双壁波纹管,包括内层直管和固定贴合于直管外表面的外层波纹管,所述双壁波纹管的一端为扩ロ的承ロ,与所述承ロ相対的一端为平直段的插ロ。
[0005] 本实用新型通过将插ロ端部分加工成平直段,増加了内层直管与外层波纹管在插ロ端的双壁接触面积,从而增加了管材双壁的粘合強度,使双壁的粘合更稳定,管材在安装时更加顺畅,不会受外力影响而使管材插ロ端的双壁粘合部分分开,从而保证了安装的质量。
附图说明
[0006] 图I是本实用新型双壁波纹管的剖面结构示意图。
[0007] 图中:ト直管;2_波纹管;3_承ロ ;4-插ロ。
具体实施方式
[0008] 下面结合附图中的实施例对本实用新型作进ー步的详细说明,但并不构成对本实用新型的任何限制。
[0009] 參阅图I所示,本实用新型双壁波纹管,包括内层直管I和固定贴合于直管I外表面的外层波纹管2,所述双壁波纹管的一端为扩ロ的承ロ 3,与所述承ロ 3相対的一端为平直段的插ロ 4。

Claims (1)

1. ー种双壁波纹管,包括内层直管和固定贴合于直管外表面的外层波纹管,其特征在于:所述双壁波纹管的一端为扩ロ的承ロ,与所述承ロ相対的一端为平直段的插ロ。
