抗冲击减噪伸缩装置在济南黄河三桥的应用

The application of anti-impact noise reduction telescopic device in Jinan Huanghe bridge

桥梁伸缩装置是保护桥梁结构安全的装置,直接影响桥梁主体质量,而传统模数式伸缩装置存在多种病害,影响桥梁安全。基于提高抗冲击能力以及降低噪音等功能,将新型抗冲击减噪伸缩装置替换传统的伸缩装置运用到济南黄河三桥,分析了该装置的结构特点、适用范围以及主要安装工艺。

The bridge telescopic device is the device to protect the safety of the bridge structure and directly affect the quality of the main body of the bridge.There are many diseases in the traditional modulus expansion device,which affect the safety of the bridge.Based on the function of improving impact resistance and reducing noise,the new type of impact resistance and noise reduction telescopic device is used to replace the traditional telescopic device in Jinan Huanghe bridge.The paper analyzes the structure characteristics,applicable scope and main installation technology of the device.
