When large-diameter natural gas long-distance pipeline is laid in Zhejiang, due to its developed economy, dense population, numerous environmental sensitive points, and the requirements of local government planning, the route for pipelines is greatly limited.At the same time, it frequently intersects with highways, railways, water conservancy and power facilities.In order to ensure the safety of pipelines and other facilities, a safe and reliable way of crossing is required.Taking Jinliwen Gas Pipeline Project as an example, this paper presents the design and construction of pipeline crossing engineering, which provides reference and guidance for pipeline engineering construction in developed areas in the future.
