CONSTRUCTION trenches for laying pipeline running tectonic faults

摘要

Problem to be Solved useful model, - increasing the reliability and economy of construction and operation of underground pipelines in areas of active tectonic faults (ATP). The technical result of the use of this utility model is to prevent discontinuities in pipeline areas and ATP increase durability trouble free operation of gas pipelines or pipelines. For this trench 1 is laid a waterproof flashing material thickness of 3 mm, thermobonded with geotextile (geomembrane) 7, on the bottom of the trench is performed drainage gravel material wrapped in geotextile 4 overlapping height of 0.3 m, with the laying perforated drainage (unperforated) tubes 5, further produce backfilling the trench with sand at a depth of 0.3 m, then laid pipe 2 and is filled with sand to a depth of 0.3 m, are placed on top insulating plate 6, and then - a waterproof flashing material 7, which is fixed galvanized steel anchors 8 and is filled with mineral soil 9. 1 yl.
