8. To Create a Gas Pipeline Profile

The profile of the gas pipeline is built for one of the longest inputs of the quarterly network. In this project: 1-2-3-4-5. On the block plan, on the selected gas pipeline, pickets are placed every 100 m, at the places where gas equipment is installed (gate valves, passages, cases), at the corners of turns, at the exit from the ground, branches .

The longitudinal profile of the gas pipeline is shown as a sweep along the axis of the gas pipeline .

Since the gas pipeline in the selected direction is less than 150 mm in diameter, it is shown in one line .

Elevations of the bottom of the trench under the gas pipeline are placed at characteristic points, for example, at intersections with roads, railway and tram tracks, engineering communications and structures that affect the laying of designed gas pipelines. The type of soil is a natural sand pad, the level of groundwater is below the depth of gas pipelines.
