Infrastructure works in general cause incalculable disorders. Every maintenance of gas networks, water, sewer, communications and energy or new installations the routine of an entire city suffers changes and problems such as traffic increased on account of deviations.
To change this chaotic scenario, non-destructive methods (MND) are a great option since in this case there is no need of trenching and movement disorders are minimized. According to the DRC, a company specialized in the field, the MND is a technology for the installation of infrastructure networks used in drilling works. Through this method of underground traverse for the installation of ducts, the periods of construction are reduced and with it the social damage caused by long days of work.
Directional drilling process or known as drilling rigs, work as follows: the machines make the pilot hole with a drill, by rotation, and injection of water and mud. After, expands the initial hole the width required for the passage of the duct, by progressive job of larger diameters, which displace and compress the soil. The end is installed the tube by probe for traction.
There are several types of MND, among the most used is the directional method. This option it is possible to drive the probe while drilling facilitating diversion of barriers or networks already present in the subsoil. The key differentiator of MND is the pull-back which is nothing more than the capacity of the equipment to pull all the accessories that were used for the passage to the other end.
The expenses for a company opt for this type of service may be higher than the ordinary piercings take into account only the amount invested in the work, but the smaller time frames and the reduction of problems raise the cost-benefit of this method.
