立面结构精细检测声呐技术在水下施工修复监测应用

Application of Facade Structure Fine Detection Sound Technology in Underwater Construction Repair Monitoring

水工泄洪建筑物导流边墙运行情况会影响水电站的安全稳定运行。近年来随着声呐技术的发展,通过声呐技术的组合使用及改进作业方案,实现了水下立面结构缺陷高精度检测,并在后续水下施工修复进程中及时获知结构三维体型变化情况,完成了水下施工修复全周期监测及施工效果佐证;通过检测成果的三维可视化、数字化展示及方量计算,为水电站水工建筑物监测、检测运维工作部署提供了有力的支撑依据。

The operation of diversion side wall of hydraulic flood discharge structure will affect the safe and stable operation of hydropower station.In recent years,with the development of sonar technology,high-precision detection of underwater facade structure defects has been realized by combination of sonar technology and improvement of operation scheme.In the subsequent underwater construction repair process,the structural threedimensional shape changes were timely known,and the whole period monitoring and construction effect proof of underwater construction repair were completed.The three-dimensional visualization,digital display and square calculation of detection results provide strong support basis for monitoring,monitoring and maintenance of hydraulic structures of hydropower station.
