Description

无缝单层翻转内衬原位固化内衬管
技术领域
本发明涉及一种管道，更确切地说，是一种无缝单层翻转内衬原位固化内衬管。
背景技术
在城市或工业管道系统中，一些老旧管线由于接近设计年限、地质沉降、地面建筑、地表植物等原因，已经出现了老化和渗漏，如果采用整体开挖更换修复，将会遇到很多不可预知的困难，如管线上的地面建筑、封闭道路影响交通、其他交叉管线的冲突、工期长成本高等，现在国际领先的方法就是各种非开挖修复技术。
发明内容
本发明主要是解决现有技术所存在的技术问题，从而提供一种无缝单层翻转内衬原位固化内衬管。
本发明的上述技术问题主要是通过下述技术方案得以解决的：
一种无缝单层翻转内衬原位固化内衬管，其特征在于，所述的无缝单层翻转内衬原位固化内衬管由内至外依次包含一内层、一加强纤维层和一胶黏层，所述的胶黏层与一管道相粘接，所述的内层为聚氨酯或柔性PE制成。
作为本发明较佳的实施例，所述的加强纤维层为涤纶或芳纶编织而成。
本发明的无缝单层翻转内衬原位固化内衬管具有以下优点：在管道非开挖修复时，施工时只需在被修复管道两端开挖两个施工坑，将该内衬管折成U型并牵引到管道内，利用外置的热固化设备对该内衬管进行扩展，使得胶黏层双向扩张，将加强纤维层和管道粘接连接，完成管道的修复。该无缝单层翻转内衬原位固化内衬管结构紧凑，施工方便，效果明显，实用性强。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明的无缝单层翻转内衬原位固化内衬管的结构示意图；
其中，
1、无缝单层翻转内衬原位固化内衬管；2、内层；3、加强纤维层；4、胶黏层；5、管道。
具体实施方式
下面结合附图对本发明的优选实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。
如图1所示，该无缝单层翻转内衬原位固化内衬管1由内至外依次包含一内层2、一加强纤维层3和一胶黏层4，该胶黏层4与一管道5相粘接，该内层2为聚氨酯或柔性PE制成。
该加强纤维层3为涤纶或芳纶编织而成。当然，采用其他类型的化工纤维也是可以的，玻璃纤维也可以，或者采用多种纤维的混合纤维进行编织。
在管道非开挖修复时，施工时只需在被修复管道两端开挖两个施工坑，将该内衬管折成U型并牵引到管道内，利用外置的热固化设备对该内衬管进行扩展，使得胶黏层4双向扩张，将加强纤维层3和管道5粘接连接，完成管道的修复。
该无缝单层翻转内衬原位固化内衬管结构紧凑，施工方便，效果明显，实用性强。
不局限于此，任何不经过创造性劳动想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求书所限定的保护范围为准。
