用混凝土筑渠道和水工建筑物,越来越广泛.混凝土每易出现裂缝,为管理工作带来很大的不便,寒冷地区因裂缝而使水流产生短路,并使建筑物失事.为防止产生这种种情况,提出我们十年来实际工作中在设计、施工、管理方面的一些见解,供水利、水管部门参考.一、混凝土产生裂缝的原因混凝土产生裂缝的原因很多,但可归结为两大类.1.由于体积变化,混凝土发生膨胀与收缩所致.这种情况也很复杂,最常见的是干缩引
Construction of concrete and concrete structures are more and more widely.Creation of concrete is easy to cause any inconvenience in management, short circuit of water flow in the cold area caused by cracks and the building crashes.In order to prevent the occurrence This kind of situation, put forward our 10 years of practical work in the design, construction, management, some of the views for water resources, water pipe department I. Concrete cracks Causes Concrete cracks for many reasons, but can be attributed to two categories .1 due to volume changes, concrete expansion and contraction caused by this situation is also very complicated, the most common is dry shrinkage
