管道淤堵的清淤技术应用

Application of Dredging Technology to Pipe Blockage

为保证排水管道清淤工作,采用联合疏通车,提高施工安全性与施工效率。描述高压水射流清淤方法的原理,即以渗透破碎和以压缩与剪切为主的清淤。给出施工工艺流程后介绍地质勘察、管道测绘、交通导行、有害气体检测、管道封堵、排水、恢复检查井等操作要点,并对管道进行功能性评估,介绍清淤设备选型、管道清淤步骤,最后出具成果报告。

In order to ensure the dredging work of drainage pipes,the joint dredge truck is adopted to improve the construction safety and construction efficiency.The principle of high pressure water jet dredging method is described,that dredging using penetration broken with compression and shear.After giving the construction process,the paper introduces the operation points of geological survey,pipeline mapping,traffic guidance,harmful gas detection,pipeline plugging,drainage,recovery inspection well,etc.It also evaluates the function of the pipeline,the selection of dredging equipment and the steps of dredging the pipeline is introduced,and finally the result report is issued.
