摘要
以涩宁兰复线天然气管道乌兰县茶卡镇段管道水毁事故为例,制定钢筋混凝土配重块和袋装砂截水墙相结合的水工保护措施,介绍钢筋混凝土配重块的设置间距计算方法和截水墙设置要求。实践表明,该水工保护措施运行效果良好。
Taking the water damage accident of Chaka Town section of natural gas pipeline in Wulan county of Sebei-Xi’ning-Lanzhou double line as an example,the hydraulic protection measure combining the reinforced concrete counterweight block and the bagged sand cut-off wall is formulated.The calculation method of the setting distance of the reinforced concrete counterweight blocks and the requirements for setting of cut-off wall are introduced.Practice shows that the hydraulic protection measure works well.
