摘要
文章首先介绍有粘结预应力加固技术的工作原理,然后从预应力孔道成型、选材下料、预应力筋穿束、预应力张拉和压浆封盖等5个方面对有粘结预应力加固技术施工过程进行了详细分析,通过分析得出了有粘结预应力加固技术施工的3个关键质量控制要点,为该技术在桥梁隧道建设中的应用奠定了夯实的理论基础。
Firstly the working principle of the bonded pre-stressed concreted technology was analyzed in this paper and then concreted technology construction process of the bonded pre-stressed was analyzed in detail from such as forming, selection of the material and filling, wearing bunch of muscle, tension process, pressure grouting and block.Finally, the conclusion of the controlling quality to the bonded pre-stressed was put forward and ramming theoretical basis to construct bridges was laid.
