摘要
为了检测长距离大埋深城市输水隧洞在长期运行后的缺陷和淤积程度,及时评价工程运行安全情况,为检修维护方案制定提供数据支撑,本研究采用小体型水下机器人携带高清光学摄像头、声呐、喷墨示踪装置,对输水隧洞表观缺陷、淤积、渗漏进行检测;并结合隧洞排空后安全鉴定、人工排查结果对水下机器人检测成果进行准确性、适用性评价。结果表明,水下机器人检测技术能够全面、准确地检测工程表观缺陷、淤积情况,并可辅助检测工程渗漏,具有安全、高效等优点,可为类似工程检测提供参考。
In order to detect defects and sedimentation degree of long-distance and deep urban water di-version tunnels after long-term operation,this study utilized a small underwater robot equipped with a high-definition optical camera,sonar,and an ink-jet device,sedimentation,and leakage within the water transmission tunnel to evaluate the operational condition in a timely manner,and provide data support for maintenance.The accuracy and applicability of the robot-based detection were evaluated by comparing the results with safety inspections and manual detection after the tunnel was emptied.The results showed that the underwater robot detection technology could comprehensively and accurately identify visible de-fects and sedimentation,and also could assist in detecting leakage.This approach has the advantages of safety and efficiency.
