北方严寒地区,冬季气温低且延续时间长,土壤冻结深,冻害对房屋的影响特别大,浅埋基础的房屋受冻害影响更为明显。房屋基础经过几个冻融周期作用,墙体就会产生各种不同程度的裂缝,不仅缩短房屋使用寿命,给使用带来很大困难,也给住户造成一定的经济损失。我们从60年代就开始采用砂垫层解决房屋基础受冻害问题,经过多年实践,深受用户欢迎。现在谈谈砂垫层基础的好处和做法。
In the cold and cold regions of the north, winter temperatures are low and the duration is long, and the soil is frozen deep. Freezing damage has a particularly large impact on housing. Houses on shallow foundations are more susceptible to frost damage. After several freezing and thawing cycles of the house foundation, the walls will produce cracks of various degrees, which will not only shorten the service life of the house, but also cause great difficulties in use and cause certain economic losses to the households. Since the 1960s, we began to use sand cushions to solve the problem of frost damage on the foundations of our houses. After years of practice, we have been welcomed by users. Now let’s talk about the benefits and practices of sand cushion foundations.
