摘要
污水处理厂水处理构筑物通常采取超长超高薄壁钢筋混凝土结构,施工过程中易出现冷缝、蜂窝、麻面、裂缝、烂根、漏筋、孔洞等质量问题,进而影响水处理构筑物的抗渗性及耐久性,需采取一定的技术方法和管理措施加以避免。文章通过隆昌市污水综合治理项目-甲子湾污水处理厂工程改良生化池施工案例,分析了超长超高薄壁水处理构筑物混凝土施工技术及质量控制方法,旨在为今后类似工程提供借鉴。
The water t reatment st ructures in sewage treatment plants usually adopt ultra-long,ultra-high and thin-walled reinforced concrete structures.During the construction process,quality problems such as cold joints,honeycombs,pockmarked surfaces,cracks,rotten roots,bar leakage,and holes are prone to occur,which in turn affects the impermeability and durability of water treatment structures.It is necessary to take certain technical methods and management measures to avoid them.This paper analyzes the concrete construction technology and quality control method of ultra-long,ultra-high and thin-walled water treatment structure through the construction case of improved biochemical tank in Jiaziwan sewage treatment plant engineering,a comprehensive sewage treatment project in Longchang City,aiming to provide reference for similar engineering in the future.
