The efficiency of the horizontal directional drilling method in the rehabilitation and modernization projects of the underground infrastructure

Abstract

"The evolution of human society was and is dependent on natural resources (oil, natural gas, coal, ores, industrial water, drinking water, etc.) and, obviously, on their transportation through pipelines. The existence of resources in the earth's crust, at depths not always accessible, required the finding of methods for their exploration and exploitation. Consequently, in the last 30 years, drilling methods, techniques and technologies have been developed. Today, the Horizontal Directional Drilling method covers the entire geological spectrum, and in terms of rehabilitation and modernization projects of the underground infrastructure, it ensures high quality. Therefore, Horizontal Directional Drilling is the smart, clean and efficient solution for installing the network sections to be installed. The authors, under the auspices of the Romanian Academy of Technical Sciences (ASTR) and the General Association of Romanian Engineers (AGIR), in this paper, highlight the use and advantages of Horizontal Directional Drilling. The main objective is to install such services in Romania without using traditional trenching methods, helping to avoid any unnecessary impact on the environment and, evidently, offering extra security.
