摘　　要：排水箱涵在给排水管网中起到重要作用,但经过长时间的运行,在多种因素的综合作用下箱涵内部逐步出现结构性缺陷,承载力大大减弱,箱涵内衬加固,对腐朽严重的老旧箱涵结构提高承载力具有较好的作用。四联河流域水环境综合整治箱涵普遍发育病害,为此提出排水箱涵内衬钢管填充混凝土加固施工工艺,该工法工艺标准化程度高,具有良好的经济、进度、社会、环保等效益。Drainage box culverts play an important role in the water supply and drainage network.However,after a long period of operation,structural defects gradually appear inside the box culvert under the combined effect of various factors,greatly weakening its bearing capacity.The reinforcement of box culvert lining has a good effect on improving the bearing capacity of old box culvert structures with severe decay.The box culvert of the comprehensive water environment improvement project in the Silian River Basin is commonly affected by diseases.Therefore,a construction process for reinforcing the drainage box culvert with steel pipe lining and concrete filling is proposed.This construction method has a high degree of standardization and has good economic,progress,social,and environmental benefits.
