随着近年桥梁施工技术的高速发展,桥梁单跨跨度和连续跨度的长度不断增大,后张法预应力施工也随之增多,预应力筋施工对桥梁整体质量和耐久性起着至关重要的作用。以下结合小浪底交通桥来阐述超长预应力筋张拉和孔道压浆施工。 With the rapid development of bridge construction technology in recent years, the length of single span span and continuous span of the bridge is continuously increasing, and the post-tensioned prestressing construction also increases. The construction of prestressed tendons is crucial to the overall quality and durability of the bridge Role. The following combination of Xiaolangdi traffic bridge to explain the ultra-long prestressed tendons tension and pore pressure grouting construction.
