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. It will be hot in about twenty or thirty days. After the summer solstice, the ground is strongly heated and the air convection is vigorous, and thunderstorms often form from afternoon to evening. ZhongYuan remind you Construction of chemical and municipal pipelines in power plants industry customer friends: the weather is hot, pay attention to heatstroke prevention!

刚性防水套管保护管道重要点

Time:2019/3/25 14:26:34

    在装置管道之前装置,在装置管道之前装置刚性防水套管时,首先要进行查看,查看刚性防水套管是否完好无缺,假如有破损要及时替换,还要查看它的尺度是否契合图纸要求,是否契合现场施工要求;其次,要查看管道有没有破损,是否有裂缝、砂眼等,有问题也要提早处理。

 

    再次,要查看承插口是不是到位,承插口本身是否密实、结实;*终,要查看管道斜度是否适宜,不能呈现倒坡状况,别的要留意,屋面出口处的管道斜度要相应地增大。

    防水套管不标准,一方面是指管道本身厚度不契合图纸要求而导致的防水套管不能运用;另一方面是指防水套管因为选用气割切开管道造成了两头有毛刺,不平坦。

    刚性套管的预留方位不准确,这一点与上面说到的防水套管要在施工过程中装置相一致,假如不是依照这一准则进行装置,很可能大致预留出来的用于装置防水套管的方位不行准确,从而导致整个施工无法正常进行。

    留意防腐蚀,假如防水套管的迎水面是腐蚀性物质,就需要使用封堵资料将缝隙封堵。例如,装置时遇到非混凝土墙面,而套管的迎水面又是腐蚀性物质,这就需要将墙面部分改为混凝土墙面,而且要确保墙面的厚度,否则达不到作用。

    楼板地上高度不适宜,在管道穿过墙面和楼板的当地应该设置金属套管或是塑料套管。在楼板内装置的套管,它的顶部要高于装修地上,一般为20毫米;在卫生间和厨房装置的套管,套管底部要和楼板底面相等,顶部一般高于装修地上50毫米左右。
