石油化工企业在生产过程中 ,需用各种不同的大中型池子 ;如工业污水、循环水、消防及下水用池子 ,多数与给排水工程的构筑物和池下工程相同 ,但在寒冷地区还要满足石油化工企业的防冻、防裂和防腐蚀的特殊要求。这些同生产紧密不可分的池类结构多采用钢筋砼建造 ,其耐久性、安 In the production process of petrochemical companies, various types of large and medium-sized pools are required; such as industrial effluent, circulating water, firefighting, and drainage pools, most of them are the same as those of the water supply and drainage works, but they are also required to be satisfied in cold regions. Special requirements for petrochemical enterprises in antifreeze, crack prevention and anti-corrosion. These pool structures, which are inseparable from production, are mostly constructed of reinforced concrete and their durability and safety
