RU95101592A - Water passing structure under embankment - Google Patents

Abstract

FIELD: water passing structures construction. SUBSTANCE: structure under embankment is mounted in the following way. Preliminary to provide conveniences to exercise works, at distance of 15 - 20 meters up the spring 3 advanced pit is dug ( Figure does not show it) and running spring 3 is partitioned. Using water pumping out equipment water is transferred to other side of pipeline 4. Flexible canal 1 is laid in dried spring mouth 3 and using cable (Figure does not show it) located under pipe 4 canal 1 is drawn down the spring 3 current till canal ends are equally spaced from center of pipe 4. Then caps 2 are introduced from butts of flexible canal 1 butts. Flexible water passing canal 1 is tightly pressed to spring 3 bottom along lower part of half-perimeter of pipe 4. On top of canal 1 and pipe 4 beginning from its center sheet 5 of nonwoven synthetic material is laid with pressing ends 6 pressed by ground and after that whole open area of pipe 4 is blanketed by ground of 0.8 - 1.0 meter thick over upper generatrix of pipe 4. EFFECT: water passing structure allows to preserve insulation, to avoid labour consumption to provide water passing in case there is laid in embankment pipeline for medium with positive temperature. 2 dwg

Claims (1)

The culvert under the embankment is mounted as follows. Previously, for the convenience of work, 15-20 m from the pipeline upstream of the stream 3, a pit is dug up and the current stream is blocked. With drainage equipment, the accumulating water in the pit is diverted to the other side of the pipeline 4. In the drained channel of the stream 3, the elastic channel 1 is laid out and, through the cable located under the pipe 4, the channel 1 is dragged downstream of the stream 3 until the ends of the channel are equally removed from the center of the pipe 4. Then from the ends of the elastic channel 1 wind up the heads 2. The elastic culvert 1 is pressed tightly to the bottom of the stream 3 along the bottom of the pipe half-perimeter 4. On top of the elastic channel 1 and pipe 4 from its center, a cloth 5 of non-woven synthetic Cesky material jamming the ends of primer 6, after which the entire open portion of the pipe 4 is filled with soil to 0.8-1.0 m from the top of the forming pipe 4.
