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!

刚性防水套管在采暖系统的安装与要求

Time:2019/4/9 12:56:55

    刚性防水套管在采暖系统中的装置及制造要求。穿过地下室或地下构筑物外墙的套管,应选用钢性防水套管,有严厉防水要求或振荡处应选用柔性防水套管。刚、柔性防水套管应按地下防水工程和规范图要求制造装置。

 

    穿过隔墙和楼板处的套管,一般选用一般套管即铁皮套管和钢管套管两种。如规划无规守时,关于穿过根底、厨房、卫生间等处,应优先选用钢性防水套管。一般钢性防水套管的制造应契合下列要求。

    刚性防水套管在制造前应按施工图要求查看预留孔洞的方位、坐标、标高和尺度;刚性防水套管的效果是便于管道的修理替换和自在弹性,要求套管的管径应比穿入的管径大1-2号;套管长度的计算方法及尺度要求:过墙套管长度等于墙厚 墙双面抹灰厚度;过楼板套管长度等于楼板厚度,板底抹灰厚度,地上抹灰厚度20mm.

    镀锌铁皮套管要卷制规整,选用咬口接缝,其直径要求与上述相同。不然,将失掉防水套管的效果,使修理换管时抽出困难,且受温度效果时,约束了自在弹性,导致管道额定受力,乃至将墙面抹灰层拉裂。刚性防水套管两头应平齐、整齐,管表里应除锈和上防腐涂层。
