Pasko .O.Z. The impact of horizontal directional drilling on surface objects
Master work is completed the research work, which was first
established on the basis of laws increasing strain on the trajectory of laying
underground pipelines constructed by horizontal drilling depending on the
category of roads.
Analysis of existing methods for assessing the stability of working which
is located forthcoming communication, regardless of the material type of
communication that is laid by horizontal directional drilling, shows that the
laying of the pipeline with a diameter of 315mm from different classes of road
surface on the maximum permissible load deformation acquire values: 29.5 *
10.3 m, 52.3 m and 10.3 * 61.57 * 10-3m when permissible load 360kN,
600kN and 690kN respectively.
