紫外光固化CIPP修复技术指的是在不改变待修复管道位置的条件下，先将浸透树脂的软管通过压缩空气充气膨胀方式，使软管与待修复管道内壁紧密贴合，再将紫外线灯放入充气的软管内，并控制紫外线灯在软管内以一定速度行走，使软管由一端至另一端逐步固化，紧贴待修复管道内壁，形成一层坚硬的“管中管”结构，从而使已发生破损或失去输送功能的地下管道在原位得到修复，是目前国际最先进的管道修复技术。

非开挖修复—UV-CIPP紫外光固化法

UV curing CIPP repair technology means that without changing the position of the pipe to be repaired, the resin-soaked hose is first inflated and expanded with compressed air to make the hose closely fit the inner wall of the pipe to be repaired, and then the UV lamp is Put it into the inflated hose, and control the ultraviolet lamp to walk in the hose at a certain speed, so that the hose gradually solidifies from one end to the other end, close to the inner wall of the pipe to be repaired, and forms a hard "tube-in-tube" structure. , so that underground pipelines that have been damaged or have lost their transportation function can be repaired in situ. It is currently the most advanced pipeline repair technology in the world.
