1982年第10期上发表的《冬施水管简易防冻法》,介绍了将地上明管内的存水排放掉能防止水管受冻,这确是一项成功并易行的好办法。结合我们多年使用的体会作如下补充。1.保温池可用砖砌成方或圆形围墙,也可用木板钉成方形盒套,中间填以草袋、锯末等保温材料。保温池(箱)的大小以能将总阀门、进气阀门都保护在中间,不受冻为合适。
The “Antifreeze Method for Winter Water Pipes,” published on the 10th issue of 1982, introduced that the discharge of water from underground pipes could prevent the pipes from freezing. This is indeed a successful and easy way. Combine the experience we have used for many years to make the following additions. 1. Insulation pools can be made of brick or square walls, or they can be nailed into square boxes, and filled with straws, sawdust and other insulation materials. The size of the heat preservation tank (box) can protect the total valve and the intake valve in the middle, and is not suitable for freezing.
