FIELD: construction. ^ SUBSTANCE: device for trenchless installation of pipes consists of basements, having windows for discharge of soil, vessel, telescopic support, power hydraulic cylinders, support plate, support wall, pushed pipe, hydraulic cylinder of quick carriage movement, carriage, stiffening ribs; hydraulic pumps. Basement is made of 1/3 diametre of pipe and has shape of hemisphere with stiffening ribs, and is located on telescopic supports with its cut facing upwards. Vessel is made of 2/3 of pipe diametre having shape of hemisphere with stiffening ribs and is arranged on basement with its cut facing upwards with the possibility to make reciprocal motions with the help of power hydraulic cylinders installed on basement. Inside body has welded support plates at the distance equal to length of power hydraulic cylinder stem and carriage. Carriage has shape of hemisphere with the possibility of displacement due to reciprocal motion of body with the help of power hydraulic cylinders arranged on basement. ^ EFFECT: improved efficiency of labour and wider range of installed pipelines diametres. ^ 8 dwg |
