在市政给水管道工程中,球墨铸铁管被广泛应用,常规的接口形式为承插式橡胶圈止水柔性接口,管道支墩对稳定管道通水作用是不可低估的。在实际工程中有些情况不能直接套用支墩图集,需根据实际情况对给水管道的支墩予以优化设计,为此通过两个工程实例,详细介绍了支墩的优化设计方法。
In the municipal water supply pipeline project, ductile iron pipe is widely used, the conventional interface form of socket rubber ring water stop flexible interface, pipe pier on the stability of the pipeline through the water can not be underestimated. In practical projects, there are some cases where we can not directly apply the atlas of embankment, and we need to optimize the pier of the water supply pipe according to the actual situation. Therefore, through two engineering examples, the optimization design method of the pier is introduced in detail.
