北方水塔漏水原因分析及处理方法

On the Reason and Solution for the Leakage of Water in Northern Water Tower

在北方由于气候原因,水塔混凝土由于冷桥造成水蒸气结霜,使混凝土保护层脱落,从而使钢筋锈蚀,钢筋锈蚀产生的膨胀,造成混凝土裂缝.水柜水位在升降过程中,混凝土受湿度和温度反复变化的影响,而使立壁产生竖向和水平裂缝.裂缝的修补可采用刚柔相兼的防水材料.

In the north, because of the influence of the weather, there often appears frost on the concsete of some water towers, which makes the protective layers on it peel off and the reinforcing bars be corroded by rust. The expansion of the reinforcing bars produced by the corrosion causes many leaks in the concrete. As a result, some cracks appear in the wall of water tower owing to the change of humidity and temperature of the concrete, which make water often leak out. To mend the cracks, we can adopt the watertight materials with both hardness and softness.
