FIELD: construction of underground pipelines. SUBSTANCE: according to proposed method, ditch is dug on slope and antierrosive panel are placed on its bottom, walls and benches, said panels being made of nonwoven synthetic material. Then pipeline is placed on said panels. Filters made of antierrosive panels are made in open ditch by turning panels into funnels whose necks are arranged down wards the slop enclosing pipeline placed in ditch and then each filter is secured in place. Fastening of each panel is provided by soil filled-in from top of slope. Filling is carried out to form angle of repose in zone of filter funnel leaving lower edge of panel free. Filter funnel is formed by overlapping friction slope of filling soil by lower longitudinal edges of panel and edges of panel are tied around pipeline forming clearance between neck of funnel and pipeline to let ground water flow run along ditch slope and regulated flow velocity in section of ditch. Upper part of funnel formed by overlapping of longitudinal edges of antierrosive panels is arranged higher than level of ground water in ditch. EFFECT: improved reliability of pipe owing to prevention of washout of ditch fill-in soil by surface water. 3 cl, 3 dwg
