    U型折叠内衬法是使用可变形的HDPE作为管道材料,施工前在工厂或施工现场先通过改变衬管的几何形状来减少其断面。变形管在旧管内九尾后,利用加热或加压使其膨胀,并恢复到原来的大小和形状,以确保与旧管形成紧密的配合。有时,还可以用一个机械成形装置使其恢复到原来的形状。
百人牛牛    管道非开挖修复技术总体分为局部修复和整体修复。局部修复也称为点状修复,是对局部的漏点进行修复,主要有嵌补法、注浆法和套管法。整体修复也称为线状修复,是对整条管线进行修复,主要有PE内衬法、CIPP法、不锈钢内衬法、碎管法、螺旋缠绕法、涂层法、短管内衬法等;其中PE内衬分为直插法、U型折叠法、O型缩径法;CIPP按施工方式分为接入法和翻转法,按固化方式分为热固化和UV光固化。U型折叠PE内衬技术和热固化CIPP内衬技术是当前国内应用广泛的工艺。 U型内衬HDPE管修复技术通常也称为紧密结合内衬法,其原理是采用外径比旧管道内径略小的HDPE管,通过变形设备将HDPE管压成U型并暂时捆绑以使其直径减小,通过牵引机将HDPE管穿入旧管道,然后利用水压或气(汽)压与通软体球将其打开并恢复到原来的直径,使HDPE管涨贴到旧管道的内壁上,与旧管道紧密的配合,形成HDPE管的防腐性能与原管道的机械性能合二为一的一种“管中管”复合结构。管道修复后在使用过程中,由于管内存在介质压力,内衬管终会紧贴于原管内壁。此类修复技术一般适用于结构性破坏不严重的直圆形管道,可适用管径范围为75~2000mm,管线长度1000m左右的各类管道。该技术因其具备卫生性能良好、过流断面损失小、变形适用范围大以及可长距离修复等优点,已广泛应用于给排水等相关管网修复工作。
