Description
技术领域
本发明属于保温管道泄漏检测技术领域，具体涉及一种具有防潮装置的瓦块预制保温管道。
背景技术
在城市市政工程中，供热管道和生活用水的供水管道都是直埋在地下，不仅充分的利用了地下空间，还有效的节省了地上空间，规范了地上空间的利用；然而，将供热管道和供水管道直埋在地下，地下环境较为潮湿，不对保温管道进行有效的防潮措施，保温管道容易受潮受损，如果保温层受损，将会影响保温管道的保温效果，在远距离输送的过程中容易造成热量损失；保温层受损程度严重时，工作管将被锈蚀，从而工作管的抗压机械性能降低，随着时间推移，管道将出现渗漏，进而影响液体的输送，甚至会影响到城市道路安全。
虽然，目前的保温管道中都左右一定的防潮防腐措施，但是这些防潮措施过于简单，防潮保护的有效时间短，当保温管道的防潮性能逐渐丧失时，保温管道的保温层和工作管道将逐渐的被锈蚀损坏，进而影响保温和输送性能；而且目前保温管道的防潮材料的柔性差，防潮层容易开裂，进而促使逐渐影响保温和输送性能，大大的减少了保温管道的使用寿命。
发明内容
本发明的目的是克服现有技术的不足而提供一种防潮效果好、耐腐蚀性强、寿命长、柔性价的具有防潮装置的瓦块预制保温管道。
本发明的技术方案如下：
一种具有防潮装置的瓦块预制保温管道，包括工作管层、保温层、防潮层以及外护套层；
所述工作管层为工作钢管；
所述保温层为硅酸钙瓦块；
所述防潮层包括防水冷胶料层、铝箔胶带层、石墨烯防潮涂层，所述防水冷胶料层直接涂覆在所述工作钢管的外表面，所述铝箔胶带层缠绕在所述硅酸钙瓦块的外表面，所述石墨烯防潮涂层涂敷在铝箔胶带层的外表面；
所述外护套层为铁皮层，所述铁皮层的外表面涂覆有防腐涂料层。
所述的具有防潮装置的瓦块预制保温管道的制作方法，包括以下步骤：
S1、将工作钢管进行清扫并保持干燥，然后将防水冷胶料涂敷在工作钢管的外表面，经过干燥形成防水冷胶料层；
S2、待步骤S1中的防水冷胶料层干燥后，将硅酸钙瓦块包覆在工作钢管上的防水冷胶料层上；
S3、将铝箔胶带沿着工作钢管的圆周方向进行紧密的呈螺旋形缠绕形成铝箔胶带层；
S4、完成步骤S3后，将调剂好的石墨烯防潮粉涂覆在铝箔胶带层上，经过干燥后形成石墨烯防潮涂层；
S5、待石墨烯防潮涂层干燥后，将铁皮层套接在石墨烯防潮涂层的外表面，然后将调剂好的防腐涂料涂覆在铁皮层干燥后形成防腐涂料层。
所述步骤S2中，防水冷胶料层的涂覆厚度为2-5mm。
所述步骤S3中，缠绕铝箔胶带时，保证铝箔胶带重叠部分的宽度不小于1/2铝箔胶带的宽度。
所述步骤S4中，所述石墨烯防潮涂层的涂覆厚度为3-7mm，涂覆时确保调剂好的石墨烯防潮粉均匀的涂覆在铝箔胶带层上。
所述步骤S5中，防腐涂料层的厚度为7-12mm。
与现有技术相比，本发明的有益效果是：本发明采用防水冷胶料层、铝箔胶带层、石墨烯防潮涂层对预制保温管道进行多级防潮保护，可有效的对直埋在地下的保温管道给予防潮保护，有效的避免保温层和工作管层受潮锈蚀，延长保温管道的实用寿命；本发明在铝箔胶带层的外表面涂覆石墨烯防潮涂层，石墨烯具有较强的柔性，且具有较强的抗老化能力，可以增强防潮涂料的柔性和抗老化性，有效的避免干燥后的防潮涂料出现开裂的情况；本发明可有效的提高保温管道的防潮性能，增强保温管道的耐腐蚀性，延长保温管道的使用寿命。
