伸缩缝是保证公路桥梁使用安全性与使用寿命的重要组成部分之一,公路桥梁在使用中往往会由于车辆经过对桥梁造成的冲击、混凝土收缩效应或是温度的变化产生的应力而对公路桥梁造成损伤,从而形成公路桥梁的安全隐患,而伸缩缝就能很好地解决这个问题。因此施工伸缩缝的质量很大程度上决定了公路桥梁的使用寿命与安全性。本文通过对公路桥梁施工伸缩缝的作用、分类介绍及其具体工艺流程、质量控制进行简单论述。
Telescopic joints are one of the most important components to ensure the safety and service life of highway bridges. In use, highway bridges often suffer from the impact of the bridge on the bridge, the shrinkage of the concrete or the temperature change, Causing damage, thus forming a road bridge safety hazards, and expansion joints can be a good solution to this problem. Therefore, the quality of construction expansion joints to a large extent determines the service life of highway bridges and safety. In this paper, the role of highway bridge expansion joints, classification introduced and the specific process, quality control, a brief discussion.
