摘要
水下构筑物是水利水电工程、桥梁工程等的重要组成部分,水下构筑物由于长期服役带来的不同程度的缺陷会直接影响整个工程的安全运行,需要及时修复;由于多种因素的影响,水下构筑物的应急检测存在较大的技术难度和安全风险。本文在某大型水利枢纽工程多项水下构筑物应急检查工作中,引进DOE T5N ROV系统及M900型图像声呐,构建了内外业一体化的测量型水下成像系统,取得了良好的应急检测效果。
Underwater structure is an important part of water conservancy and hydropower engineering,bridge engineering and so on.Due to the long-term service of underwater structure,the defects of different degrees will directly affect the safe operation of the whole project,which needs to be repaired in time.Due to the influence of many factors,the emergercy detection of underwater structures has great technical difficulties and safety risks.In this paper,DOE T5 N ROV system and M900 image sonar are introduced into the inspection of underwater structures in a large water conservancy project,and an integrated measurement underwater imaging system is constructed,which achieves a good emergercy detection effect.
