安全和稳定是桥梁的保障,伸缩缝是桥梁组成的重要组成部分,对桥梁上部结构和各结构之间起链接和位移作用。伸缩缝的施工要求高、技术难度高,后期修复难度大,且在施工过程中也很容易出现损坏,直接关系到桥粱安全和公路桥梁的寿命大大缩短,对于车辆行驶状况造成严重的恶化。本文就公路桥梁伸缩缝的重要性以及公路桥梁普遍存在的问题进行了阐述,其次,就如何有效的加强公路桥梁施工中伸缩缝的质量控制进行了探讨、并提出了自己的见解。希望能与同行交流,共同将公路桥梁工程的质量提高。
Safety and stability are the guarantee of the bridge. The expansion joint is an important component of the bridge, which plays the role of link and displacement between the superstructure and each structure of the bridge. The construction requirements of expansion joint are high, the technical difficulty is high, the later repair is difficult, and the damage is also prone to occur during the construction process, which is directly related to the safety of the bridge beam and the shortening of the service life of the highway bridge, which seriously aggravates the driving conditions of the vehicle. This paper describes the importance of highway bridge expansion joint and the common problems of highway bridges. Secondly, it discusses how to effectively improve the quality control of expansion joints in highway bridge construction and puts forward my own opinions. Hope to be able to communicate with their peers, together to improve the quality of highway bridges.
