WATER-ESCAPE STRUCTURE UNDER EMBANKMENT Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: this structure is used in construction and repair of pipelines, and erection of embankments. Placed along bed of streamlet are lengths of pipes for water passage. Connected to one of pipe lengths by means of welding are perforated vertical pipes which are wrapped in filtering material and closed atop with caps. Water passing pipes are covered with earth for creation of embankment. Gas pipeline which crosses water streamlet is located in embankment. Creation of banking-up of gas pipeline with earth is undertaken for formation of carriage way along gas pipeline route. Freshet water is directed into vertical pipes and branched into pipe lengths for bringing away together with water flowing in streamlet. Application of aforesaid embodiment of structure reduces water saturation of gas pipeline banking-up and enhances its stability. EFFECT: higher efficiency. 1 cl, 3 dwg
