声呐检测系统在排水管道淤积调查中的应用

Application of Sonar Detection System in Drainage Pipeline Sediment Survey

城市排水管道担负着城市排涝除渍、治污环保的职能,排水管道淤积极易导致严重内涝。声呐探测系统通过声呐探头发射声波和接收反射回波判断管道断面的管径、沉积物形状和变形范围,适用于充满度高的污水管道。通过采用声呐检测系统调查污水管道冒溢原因,管道淤积检测结果与人工量测埋深结果一致,并利用管道沉积状况纵断面图估算管道淤积量。由于其具有检测简单、成本低、效果好等优点,可有效指导和评估日常管道疏捞养护工作。

Urban drainage pipeline is responsible for the functions of preventing waterlogging,pollution control,and environmental protection.The blocked drainage pipeline is prone to cause serious waterlogging.The sonar detection system can estimate the drainage pipeline diameter,sediment shape,and deformation range by emitting sound waves and receiving reflected echoes through sonar sensor,which is suitable for high-filled sewer lines.The sonar detection system was used to investigate the cause of overflow of sewer lines.The sediment detection results by sonar detection system are consistent with the results by manual measurement.And,the sediment deposition in sewer lines is estimated by using profile diagram of sediment state.The sonar detection system has the advantages of simple use,low cost,and good effect,which can effectively guide and evaluate daily drainage pipeline maintenance.
