World Trenchless Technology Day (22/09)

Every fourth Thursday in September became the unofficial World Trenchless Day. This decision was made at a seminar held in Moscow in 2016 as part of a whole range of events organized by the International Association of Horizontal Directional Drilling Specialists.

The field of underground utilities is associated with many technologies for laying them, but what stands out is the method, the use of which makes it possible to solve the problem when the external opening of soil layers is difficult, impossible or possible, but entails certain negative consequences.

Horizontal directional drilling (GNB) technology is one of the most modern in the field of laying underground utilities. Advanced technologies and equipment in the fields of hydraulics, mechanics, chemistry, electronics, etc. are involved here.

Thanks to GNB technology, it is possible to lay pipelines of different diameters and different lengths without opening the upper layers of soil. Modern drilling equipment and equipment allow such work to be carried out in different climatic conditions, as well as in different types of soil.

Horizontal directional drilling technology was born in the 1960s and has developed steadily since then, as has the equipment used for this type of work. The start of work on GNB technologies is preceded by an analysis of the soils through which it will be necessary to lay underground communications. This is followed by the stages of drilling a pilot well, expanding it, laying a pipeline through the well and connecting the laid section of underground communications to the system.

The use of horizontal directional drilling technology makes it possible to solve a whole range of problems when laying utilities: under highways, trams or railways, under forests, rivers, ravines, power lines, in dense residential areas, etc.

The inability to use such a method inevitably leads to an increase in the cost of the process due to an increase in the length of communications, the need to restore the upper layers of soil disturbed by excavation, as well as ground communication structures and infrastructure, attracting earth-moving equipment and additional labor…

In addition to the economic aspect, characterized by cost reduction, the use of the GBV method when laying underground utilities makes it possible to minimize the negative impact on the living conditions of people in the work area. No less important remains the fact of minimizing interference in the eco-balance of the territory through which communications are laid.

Therefore, the main goal of Day — is to emphasize the production, technical, economic and socio-environmental advantages of GNB technology and, of course, congratulate all specialists working in this branch of the construction complex on their professional holiday.
