双曲线冷却塔的渗水现象属于质量通病,不但影响质量和美观,而且会缩短冷却塔的使用寿命。冷却塔的筒壁是钢筋混凝土薄壳结构,是在相当恶劣的条件下工作的。因此要求混凝土必须特别密实,要严格按照设计要求施工。混凝土配合比必须经技术部门通过试验后确定,碎石的颗粒级配应满足质量标准规定,使用前冲洗干净。混凝土浇筑前,应对钢筋、模板、三角架等进行全面检查,符合要求后用水将施工缝冲洗干净,用赶浆法先浇一层水泥砂浆,使上
The seepage phenomenon of the hyperbolic cooling tower is a common problem of quality, which not only affects the quality and aesthetics, but also shortens the service life of the cooling tower. The wall of the cooling tower is a reinforced concrete thin shell structure that operates under rather harsh conditions. Therefore, it is required that the concrete must be extremely dense and must be constructed in strict accordance with the design requirements. The concrete mix ratio must be determined by the technical department after the test. The particle size distribution of the gravel should meet the quality standards and be washed before use. Before pouring concrete, comprehensive inspection shall be conducted on steel bars, formworks, tripods, etc., and the construction joints shall be flushed with water after meeting the requirements, and a layer of cement mortar shall be poured first with slurry
