Installment of thrusted and gravitational sewing and drainage lines without trenching and digging.Ĭhannels of communication pipelines for protection and safety of power cables for high, medium and low voltage, as well as TV, optical, telephone and other telecommunication cables.ĭrilling Construction Ltd. ![]() Water supply – convalescence of old Water Supply and Sewage pipelines (thrusted and gravitational) or installment of new ones without digging. The method of Guided Horizontal Drilling without Digging, with minimum or without any digging activities of channels, possesses a wide variety of application within all building activities such as: Horizontal directional drilling is successfully applied at locations with complicated infrastructure, as well as locations where it is impossible to dig or it is not preferable – under crossroads, buildings, rivers, asphalt roads, railways, bridges, motorways, when designing building junctions, park facilities, etc. Horizontal directional drilling has developed and spread rapidly, and has established itself as one of the best methods because of its eco friendliness, practical and minimum damages to the environment. Horizontal directional drilling is a relative newcomer to the environment industry in Bulgaria for pipeline installment without digging. The horizontal drilling method is a precisely guided process – it is possible to construct horizontal drilling within up to 0.1 % of the dimensions prescribed by means of the directional drill method, which allows the technician to locate and control constantly the operating drilling parameters. The Horizontal Directional Drilling Method (HDD) is also called Guided Boring, Micro tunneling and horizontal hammering (pneumatic moles, hammers, etc.). Using directional drilling, e.g.The horizontal directional drilling method is A RAPID, PRECISE, CLEAN AND PROFITABLE MODERN SOLUTION!

The drilling fluid consisting of water and the organic clay mineral Bentonite supports excavation of the soil, removes the cuttings, stabilises the bore channel and reduces the friction of the casing of the pipe. That way, longitudinal bores, crossings and underpasses of waters and other traffic ways can be carried out using HDD drilling even in rocky ground. When the drill rods are pulled back, the borehole is upsized by an expanding head and the pipe attached is pulled into the bore path. Withfluid-assistedHDDthe GRUNDODRILLdirectional drilling machine (not to be confused with a jetting machine for hydro cleaning) first creates a pilot bore along a flexible bore path using a steerable drilling head.
