                      落水管和排水管之间的区别

                      落水管是专门收集屋顶上的雨水,并将水排到地面上的一种管材。这在农村的自建房很常见,对于城里的高楼大厦,还没有这么长的落水管,即便是可以连接,也不是很安全。
                      排水管其实也很好理解,它被分为雨水管系、污水管系及合流管系。因此排水管我们随处可见,比如家装中的水管就属于排水管中的一种。
                      两者存在的一个很明显的不同就是适用于的范围不同,落水管用于室外,而排水管则是室内外都可以用。管壁厚薄不同,落水管的管壁比较薄,这是考虑到两个问题,一是担心落水管安?#23433;?#29282;固下坠?#19994;?#20154;,危及人身安全;二是它不是承压管路,管壁加厚浪费成本。而排水管的管壁基本上都比较厚。
                      另外还有材?#23460;?#27714;的不同,落水管是长期处于室外,经历着风吹雨淋,所以?#35805;?#30340;落水管都是具有防紫外线功能的;而排水管就不会有这种功能。在安装上,两种管材的计算方式不同,落水管?#21069;?#29031;关键单?#28010;悖?#32780;排水管则是将管件含在了定额内
                      Drainage pipe is a kind of pipe which collects rainwater from roof and discharges it to the ground. This is very common in rural self-built houses, for high-rise buildings in the city, there is not such a long downspout, even if it can be connected, it is not very safe.
                       
                      Drainage pipes are also well understood. They are divided into rainwater pipes, sewage pipes and confluence pipes. So we can see the drain pipe everywhere, such as the water pipe in the household fittings belongs to one of the drain pipes.
                       
                      One obvious difference between the two is that the scope of application is different. Drainage pipes are used outdoors, while drainage pipes can be used indoors and outdoors. Because of the different thickness of the pipe wall, the wall of the downcomer is thin. This is due to two problems. One is that the installation of the downcomer is not strong enough to fall into people and endanger personal safety; the other is that it is not a pressurized pipeline, and the cost of thickening the pipe wall is wasted. The wall of the drain pipe is basically thicker.
                       
                      In addition, there are different material requirements, downspouts are long-term outdoors, experiencing wind and rain, so the general downspouts are anti-ultraviolet function; and drainage pipes will not have this function. In installation, the calculation methods of the two kinds of pipes are different. Drainage pipes are calculated separately according to the key points, while drainage pipes include the fittings in the quota.
