摘要
本文介绍了大型河道冲击坑防护所采用的水下抛填格栅石笼和砂袋防护的设计与施工方法,该工法使用船载GPS和带声纳装置的超声波水位计进行水下高程测量与控制抛填位置和方量。此外,本文介绍了关键部位水下防护最前端包角与最后端齿墙根部的设计与施工措施,对类似工程有借鉴价值。
In the paper,design and construction methods of throwing and filling grid gabion and sandbag protection in large river impact crater protection are introduced. Onboard GPS and ultrasonic water level with sonar device are adopted in the method for underwater elevation measurement and control of throwing and filling position and volume. In addition,design and construction measures of forefront corner and the final end key-wall root in key part underwater protection are introduced in the paper,thereby providing reference for similar projects.
