CIPP原位固化工艺pipe)利用既有管位，树脂现场固化形成有结构CIPP(cured-in-place-强度的内衬。原位固化工艺是世界上应用最为广泛的管道非开挖修复工艺，根据固化原理的不同可分为:热水固化、紫外光固化和蒸汽固化。

CIPP(cured-in-place-pipe ),which produces high-strengthstructural internal material with existing pipeline and resincuring,is now a worldwide Pipeline Trenchless Repairtechnology.ClPp has three different installation methods: hotwater, UV-ight and sleam.

CIPP原位固化工艺

螺旋缠绕修复

螺旋缠绕管是一种采用机械缠绕的方法，将带状PVC型材在原管道内缠绕形成新的管道内衬的非开挖修复工艺，可带水作业。

Spiral winding pipe forms belt-typed PVC material into newinternal material in pipeline by mechanical bind. lt is able towork in water.

点状原位固化修复

利用树脂固化原理在管道局部破损、脱节、局部腐蚀等缺陷处形成内衬的修复方法，常用的点状原位固化工艺有紫外固化、常温固化。

Spot ClPP aims to shape new internal material wherever it partiallydamages, disjoints, or partially corrodes based on Resin CuringTheory. Common Spot CIPp includes UV ClPp and Room Tempera-ture CIPP.

不锈钢双胀环

以双不锈钢圈固定、橡胶密封的一种局部接口管道非开挖修复工艺，多用于中大型管道接口渗漏、错位、脱节等缺陷修复。

Stainless Steel Double Expanding Ring Repair, which is a kind ofTrenchless Repair, fixs partial pipeline with stainless double steelring and seals up pipeline by rubber, is mostly applied to repairmedium or large type pipeline wherever it leaks, malpositesdisjoints, etc.

内衬法

内衬法CIPP工法应用于检查井修复，可形成具有一定厚度和强度的窖井内衬，延长检查井的使用寿命。

When applied to Manhole Repair, ClPP forms certain strength andthickness manhole internal material, in order to extend the life ofmanhole.

喷涂法

在预处理后的检查井内壁上喷涂水泥、砂浆等化学材料，喷涂厚度、强度可根据需要控制。

By spraying chemical material like cement and mortar on thepretreated manhole. The level of strength and thickness dependson your need.

玻璃纤维贴层法

高强度玻璃纤维配以常温或紫外光固化树脂贴于检查井内壁，形成一体的检查井内贴层。

Hi-strength fiberglass is attached to the inner wall of manhole with roomtemperature or UV curing resin, accordingly form new manhole layer.
