Long-life abrasion-resistant repair technology
According to the long-service-life abrasion-resistant repairing technology for the hydraulic release structure, a strain strengthening type inorganic metal abrasion-resistant material is adopted and matched with two innovative auxiliary materials, namely hydrophilic low-viscosity polyurethane modified interface glue TG and a high-thixotropy rheological modifier TV, and the long-service-life abrasion-resistant repairing technology for the hydraulic release structure is achieved through the innovative structural design and the construction technology. The repaired anti-abrasion surface layer structure has the excellent anti-abrasion performance of high strength, high toughness, high crack resistance, high impact resistance, high abrasion resistance and high aging resistance, and can coordinate deformation with foundation concrete, common interface problems such as layer staggering, debonding and hollowing in a traditional repairing technology are eliminated, and the long-acting service life is achieved. The service life of the abrasion-resistant surface layer with the thickness of 3 cm reaches more than 7 years, secondary maintenance is not needed in the process, a large number of manpower and material resources needing to be input due to repeated abrasion damage in the traditional technology are saved, the full-life economical efficiency of the abrasion-resistant structure is remarkably improved, and the operation safety of the dam is better guaranteed.
本发明公开了一种用于水工泄水建筑物的长寿命抗冲磨修复技术，采用应变强化型无机金属抗冲磨材料，配合两种创新性辅材——亲水性低粘度聚氨酯改性界面胶TG和高触变性流变改性剂TV，通过创新结构设计和施工技术，使修复后的抗冲磨面层结构拥有高强高韧、高抗裂、高抗冲击耐磨蚀、高耐老化的优异抗冲磨性能，并可与基础混凝土协调变形，消除传统修复技术常见的界面问题如错层、脱粘、空鼓等，实现长效服役寿命。3cm厚抗冲磨面层的使用寿命达到7年以上，期间无需二次维修，节约传统技术因反复冲磨破坏而需要投入的大量人力物力，显著提高抗冲磨结构的全寿命经济性，更好保障大坝运营安全。
