Описание: The horizontal directional drilling technique (HDD) is on the way up at the moment. Directional drilling operations unheard of in the past, now belong to the everyday scene on a job site. Application of HDD units make longitudinal installations up to 500 m possible. Crossings beneath rivers and other waters are frequently performed. The directional method even makes drillings beneath industry complexes possible. The range of application includes all pipe construction measures within the bounds of gas, district heating and drinking water supply, the installation of pressure lines for sewers as well as cable protection pipes for television or telephone cables, traffic routing systems, emergency call boxes or low, medium, high voltage and optical fibre cables.
