桥梁伸缩缝是桥梁上部构造的薄弱部位,直接承受汽车荷载的反复冲击作用,桥梁伸缩缝的施工质量对桥梁结构的稳定性、行驶过程中的安全性和舒适性有着直接影响,因此桥梁伸缩缝施工是高速公路施工项目中的重中之重。但桥梁伸缩装置长期暴露在空气中,环境变化不定,是桥梁结构中最易受损伤的脆弱部位,因此采取有效措施改善和提高桥梁伸缩装置的耐久性和使用效果势在必行。
Bridge expansion joints are the weak parts of the upper structure of the bridge and are directly subjected to the repeated impact of automobile loads. The construction quality of bridge expansion joints has a direct impact on the stability of the bridge structure and the safety and comfort during driving. Therefore, the expansion joints Construction is the top priority of highway construction projects. However, the long-term exposure of the bridge telescopic device to the air and the fluctuating environment make it the most vulnerable part of the bridge structure. Therefore, it is imperative to take effective measures to improve and enhance the durability and effectiveness of the bridge telescopic device.
