FIELD: construction.SUBSTANCE: device for trenchless installation of pipelines, comprising a guide body arranged on telescopic supports with a cut upwards, made of a 2/3 diameter of the pipe in the form of a hemisphere reinforced with stiffening ribs, having inside the welded thrust plates at the distance equal to the length of the power hydraulic cylinder stem, windows for soil discharge, stop wedges, a grip, differing by the fact that a carriage made as telescopic of double-sided action, having thrust sliding plates, an opening for soil transportation, is arranged inside the guide body transferring the force of power hydraulic cylinders installed on the telescopic carriage of the double-sided action.EFFECT: higher efficiency of labour, expanded range of installed pipelines diameters, lower labour intensiveness.10 dwg |
