The mining conditions Ukrinvestbud

In addition, with an overground laying, the influence of soil deformations on the pipeline is minimized, and the end of the pipeline to the surface where it is possible for architectural reasons is the most appropriate. However, the above -ground laying is little applicable for transporting the medium subject to freezing (water, gas containing freezing components, etc.

Recently, in cities and villages with multi -storey buildings, gas pipelines have been mounted on the walls of the courtyard facades of houses. Inputs in the sections of the houses are carried out through casings that are not tied to the walls of the building.

With mutual horizontal movements of an array of soil and the associated pipeline on their contact, tangent stresses occur. The stresses in the pipes caused by the part -time work depend on the nature of the move process and the method of laying the pipeline.

The mining conditions of the part -time gas pipelines in the Donbass. The above factual data reflects a wide range of conditions for the part -time gas pipelines and their diverse technical characteristics. In the Donbass, the aboveground gas pipelines are currently mounted on reinforced concrete supports – single -axial moving and dioxide fixed (dead). The distance between the columns is taken from 10 to 30 m and depends on the diameter of the gas pipeline.   Fixed (anchor) supports are installed at a distance of 100-200 m from each other. Compensators are installed on the gas pipelines: lens (on low-pressure gas pipelines) and P-shaped (on high-pressure gas pipelines). The outcome of the part -time work of all these gas pipelines was favorable.

From the point of view of the mountain condition, the range of part -time work of gas pipelines is characterized by the following:

a) the fall of the layers from hollow to steep;

b) various depths of part -time job (from 40 to 600 m);

c) development under gas pipelines of not only single, but also the retinue of layers.

Estimated data but the costs of the implementation of protective measures applied on pipelines in the conditions of part -time communication.
