摘要
排水管道在长期的运行过程中,因荷载、淤积、老化等原因出现各种结构性和功能性病害使其不能发挥应有的作用。结合工程实践,分析了排水渠箱的结构性和功能性病害情况,根据病害特征确定喷涂修复技术的工艺参数,介绍了喷涂修复施工过程的工艺流程,并对施工过程中需要注意的问题进行了论述。实践表明,喷涂非开挖修复工艺是一种操作简便、绿色环保、环境影响小的新型的排水管道修复方法,在我国具有广阔的应用前景。
In the process of long time run of drainage pipelines,sorts of structural and functional defects caused by load,sedimentation and aging interfers the function of the pipes.This paper analyzed the structural and functional defects of the drainage box combined with engineering practice.,According to the disease characters,the repair parameters of spraying trenchless repair method were determined.The construction technological process of this method was described,and the problems caused were discussed.The construction practice showed that spraying trenchless repair technology would have a broad application prospection in China,with its advantages of convenient operation,environment friendly protection and little environmental impact.
