摘要
对倒虹管式三种施工方案进行对比,阐述围堰法、沉管法的技术核心及施工注意事项,针对渭河甘肃段过河管道工程情况选出较适用的施工方案——顶管法施工。对工程实际问题进行总结,如顶管受阻、顶管失稳等,提出了解决措施,以降低顶管工程的风险。
In this paper, three construction schemes of inverted rainbow pipe are compared, and a more suitable construction scheme, pipe jacking method, is selected according to the concrete situation of the pipeline project in Weihe River Gansu section. The practical problems of the project are summarized, such as obstruction and instability of pipe jacking, and corresponding solution measures to reduce the risk are put forward.
