我们如何安全地渡河
当计划建造一条新的管道时, information is gathered about water bodies along a proposed pipeline route. 这个信息, 还有法规要求, 行业最佳实践, 可建造性和经济可行性, 是用来确定管道安装方法的吗.
在我们的 渡水情况说明 or watch the video below to learn more about the techniques we use to cross rivers and streams when installing new pipelines.
案例研究:
重新治理河流
In June 2013, heavy rainfall triggered catastrophic flooding in major southern Alberta rivers. The one-in-200-year flood exposed four of the natural gas pipelines on our NGTL System where they cross the rivers – creating a potential issue that needed to be addressed. The project team used a mix of soft engineering and bioengineering practices to “re-train” the river – essentially giving the river new engineering skills to help it do a different job, 同时最大限度地减少公司的环境足迹.
例如:
- 全球十大赌博靠谱平台西蒙内特河管道修复项目, groynes were built to deflect water away from the river bank to prevent further erosion, channeling the flow of water to its original path so that debris and sediment would be deposited in the back eddies, thus reinforcing the eroding bank and establishing new habitat for fish.
- 在另一个项目中，我们创建了一个通道内窗台. A trench was constructed downstream of the pipeline and filled with rock so that the depth of cover over the pipeline would increase as the river naturally picked up and deposited granular material at the sill.
