Abstract:
Pipelines are used to carry cement in the 4th stage of Huang Tai Power Plant Project, in which the method to lay pipelines by vibration through explosion for ipeline crossing the Yellow River. The article gives a brief introduction to the crossing project, selection of pipeline configuration and calcualion. More space is given to the description of the concrete operation and steps taken in the project. Practice proves that cement pipeline configuration design is practical and such a method quite applicable for pipelines to cross tbe Yellow River at middle and lower reaches, which an not only secure thr designed cover depth as required but economize considerable investment as well, showing satisfactory economic efficiency.
