![]() The method of implementation can be seen in the diagram below.Īfter completing the bore, we can decide to leave the pipe as protection for media cables, or to remove the protective pipe from the bore at the same time as ramming the new sewer, polypropylene, gas or polyester pipes. In very difficult terrains, bentonite is added to the bore, serving to reduce the pressure on the head. The drilled material is transported to the entrance pit at the drill. The method of implementation can be seen in the diagram below.Īfter completing the pilot bore, an adapter for the desired diameter of drilling is installed on the pilot rods, and drilling of this diameter begins. Follow ESID procedures in operator’s manual. Do not touch pipe with hands or hand-held tools. We have various drill heads available, depending on the type of ground, including rocks, to be drilled. Warn others nearby that an electric strike occurred and to stay back. First, a pilot bore is made with a suitably sized drilling rig. As a result, the machine is extremely accurate. Horizontal directional drilling (HDD) consists of several installation steps. based on using special drilling machines. The camera itself detects changes in elevation of 0.001 mm. Horizontal Directional Drilling or HDD is a controllable trenchless method of laying underground pipelines like water, sewer, drainage, oil, gas, cables under road, bridges, landscape, river, metro etc. We can control and monitor the bore with an accuracy of +/- 1 cm per 150 m. Implementation of subsurface drilling consists of three phases: Installed pressurised pipes may be polypropylene (Hobas), polyester or polyethylene. Possibility of direct installation of sewage pressurised pipes, without protective metal pipes. These pits will collect and reclaim drilling fluid, reducing cost and preventing waste. ![]() Possibility of installing protective metal pipes The process begins by creating a receiving hole and an entrance pit.Successive reamers are then pulled back to enlarge the bore diameter to the desired size. The bore is steered to create an initial hole at the required line and grade. ![]() Implementation of bores in all types of ground, including rock Horizontal directional drilling (HDD) consists of several installation steps.This technology has many advantages over other known technologies: Implementation of diameters from f 110 mm to f 900 mm Horizontal directional drilling (HDD) becomes as a favorite crossing method in many situations for the installation of oil and gas pipelines as well as other utilities and transposition of obstacles. ![]() The technology is suitable for construction and rehabilitation of sewers. We present a new horizontal drilling method using optical control. ✺ccurate implementation and guaranteed precision even for longer bores in the most demanding terrains.« ![]()
