Thank you for your attention to ZhongYuan water supply equipment [Knowledge News Information] column! The summer solstice is one of the early confirmed solar terms in the 24 solar terms. In the seventh century BC, the ancestors used Tugui to measure the sun's shadow, and determined the summer solstice. Although the summer solstice indicates that the hot summer has arrived, it is not hot yet. The temperature will continue to rise for a period of time after the summer solstice.

  怎样处理穿墙管渗漏问题?

  1.从正面拆除管道周边的面层及结合层直至原结构层表面(拆除宽度为300mm)。注意:原防水层应保留150mm完好无损;

  2.管道与楼板的交接处剔槽,槽的宽度为20mm,深度为30mm,若管道周边松懈面积较大,则不能在管道周边剔槽,以避免管道周边后吊模的砼坠落;

  3.用小型吸尘器将基面渣土及杂物整理干净,然后采用防水堵漏宝或水泥砂浆修补基层;

  4.铸铁管管道根部采用钢丝刷打磨除锈或 PVC 管道打磨增糙处理;

  5.在槽内嵌填密封胶并采用堵漏宝抹弧掩盖处理,在修补的基面上进行新做防水附加层施工,防水附加层需内衬网格布,网格布平面搭接宽度为 150mm,立面搭接高度应与面砖相等,然后在涂刷与原防水层相容的涂膜防水层,保证新做防水层应与原防水层搭接宽度 150mm,老防水层的搭接部位应干净,无尘埃;

  6.康复垫层(水泥砂浆层),在新做涂膜防水层上抹水泥砂浆保护层;

  7.防水层固化后,在修理部位进行 24 小时闭水试验;

  8.康复结合层及面层至原状。
