1.水工建筑物的加固、补强。水工建筑物大多在复杂的地形、地质条件下修建,并经常处于干湿、冻融交替的环境中,在使用期间难免出现一些质量问题需及时处理。采用预应力技术进行加固和补强,是有效措施之一,如对大坝的加固、船闸裂缝处理、地下厂房锚杆断裂事故处理等。 1. Hydraulic building reinforcement, reinforcement. Hydraulic structures are mostly built under complicated topography and geological conditions. They are often exposed to dry-wet conditions and freeze-thaw cycles. Some quality problems are inevitable during use and must be dealt with promptly. The use of prestressed reinforcement and reinforcement technology is one of the effective measures, such as the reinforcement of the dam, shiplock crack treatment, underground plant bolt fracture accident treatment.
