陆水水利枢纽8号副坝坝坡因长期受风浪、水流侵蚀冲刷,受损严重,坝体存在渗漏现象,需进行护坡加固。护坡采用水下模袋混凝土加固,详细介绍了水下模袋混凝土的施工流程、方法,以及施工过程中的质量控制和应急措施,护坡完成后,检查结果满足设计要求。在经历了2008年的冰冻灾害及近几年的水流冲刷考验后,护坡完好无损,证明采用水下模袋混凝土护坡是成功的。
Due to the long-term storm surge and water flow erosion, the auxiliary dam slope of No. 8 Luzhou Water Conservancy Project is seriously damaged due to wind and water erosion, and the dam body needs to be leveled for reinforcement. The slope protection is reinforced by underwater bagging concrete. The construction flow and method of underwater bagging concrete, as well as the quality control and emergency measures during construction are introduced in detail. After the completion of the slope protection, the inspection results meet the design requirements. After experiencing the freezing disaster in 2008 and the scouring of water current in recent years, the slope protection is intact, which proves that it is successful to adopt the underwater mold bag concrete slope protection.
