Description

一种CIPP翻转式热水固化法用的填充浮球 技术领域
本实用新型涉及管道非开挖修复技术领域，尤其是涉及一种CIPP翻转式热水固化法用的填充浮球。
背景技术
近年来，随着我国城市化进程的加快，城市交通和商业活动十分繁忙，对城市排水管网维护采用非开挖修复技术越来越多。城市管网非开挖修复技术分类有多种，其中使用最为广泛的是原位固化法(CIPP)，CIPP又以翻转式热水固化法适用范围最广，CIPP翻转式热水固化法是在非开挖的情况下，将浸渍树脂的软管一端翻转固定在修复管道入口，然后利用水压使软衬翻转推进置入原有管道内，再向软管内的充水循环加热使软管固化成型，形成坚硬内衬软管的修复方法。
使用热水固化相比蒸汽能更好控制介质温度，也能避免蒸汽液化积水导致固化不充分问题，且利用水的流动性带动材料翻转和前进对于大管径及异形管的修复更具优势，但该法需大量烧煮热水，造成资源浪费，甚至易产生热水排放造成下游水体热污染。且加热固化温度一般20℃升到95℃保持一段时间再降温，内充水量大时水温调节就难控制，且作业时间太长，单开始加热到固化再到降温至38℃时就需18小时左右，工效太低，现有技术中的翻转式热水固化法，用水电量极大，水温升降控制难，作业时间长，容易造成水热污染。
实用新型内容
本实用新型的目的在于提供一种CIPP翻转式热水固化法用的填充浮球，以解决现有技术中的翻转式热水固化法，用水电量极大，水温升降控制难，作业时间长，容易造成水热污染的技术问题。
本实用新型提供一种CIPP翻转式热水固化法用的填充浮球，包括浮球、固定螺丝、金属网罩和钢丝，所述金属网罩环绕设置在浮球的外侧，所述固定螺丝固定安装在金属网罩上，并且所述固定螺丝的输入端延伸到浮球外壁，所述钢丝设置在金属网罩上，所述钢丝与所述金属网罩相连接。
进一步的，所述金属网罩与浮球有间隙。
进一步的，所述固定螺丝设有若干个，若干个所述固定螺丝环绕安装在浮球与金属网罩之间，用于保持浮球与金属网罩相对固定。
进一步的，所述钢丝将浮球、金属网罩和固定螺丝串连成链。
进一步的，所述浮球的直径为管道内径的1/10～1/3。
与现有技术相比较，本实用新型的有益效果在于：解决CIPP翻转式热水固化法需大量烧煮热水，造成资源浪费，甚至易产生过多热水排放造成下游水体热污染的问题，解决了加热阶段水温调节所需时间长，固化工效太低的问题。
