新老桥拼接的纵向拼缝由于受两侧桥梁沉降不均匀和车辆通过时振动产生的挠度这两个因素的影响,非常容易损坏,是桥梁设计和养护过程中的一个难题。为了解决这个问题,必须使用弹性材料,它既要能满足沉降不均匀带来的变化,又能满足车辆行驶引起的挠度变化,使得在拼缝处理后能保证拼缝处平顺连接。现以中州大道新老桥拼接施工为例,浅谈一下GD弹性混凝土柔性拼接的技术研究。 Longitudinal patchwork of the new and old bridges is easily damaged due to the uneven settlement of the bridges on both sides and the deflection caused by the vibration of the vehicle passing through it. This is a difficult problem in the design and maintenance of bridges. In order to solve this problem, it is necessary to use elastic material, which can not only meet the requirements of uneven settlement, but also meet the deflection caused by the running of the vehicle, so as to ensure the smooth connection of the patchwork after the patchwork. Now Zhongzhou Avenue Bridge construction as an example, talk about GD flexible concrete splicing technology.
