METHOD FOR UNDERGROUND LAYING OF CABLES AND POLYETHYLENE PIPING THROUGH SHORELINE |
摘要 |
electrical engineering; routing cables and polyethylene pipes from land to water and vice versa. SUBSTANCE: service-line well is drilled from land so that it crosses shoreline under the earth and its face emerges from ground to water in water reservoir and watercourse bottom. PVC casing pipe is drawn through service- line well. Cable and polyethylene piping are passed through PVC casing pipe. Same procedures are carried out on opposite side of water reservoir and watercourse. Underwater mouths of both service-line wells are joined by means of trench, cable and polyethylene piping are laid between mouths, and trench is filled up. EFFECT: improved quality of cable and piping laying, reduced construction time, improved environmental friendliness of method. 2 cl, 4 dwg
