Horizontal directional drilling construction characteristics of Dongguan Shenlong horizontal directional drilling rig construction manufacturers specializing in the provision of professional construction machinery, it can be the laying of pipes, cables and other public facilities in the state not ground excavation. Then the horizontal directional drilling in the construction of what is characteristic? Dragon for you summed up its characteristics, we hope to help you understand us. (1) Unlike traditional conventional excavation and construction technology, horizontal directional drilling does not hinder the role in the construction will not affect the traffic, it will not destroy the vegetation and the school and residents of a normal life and work. The level of modernization (2) through the high precision directional drilling equipment, to meet the general design requirements, horizontal directional drilling rig prices, and laying direction can be adjusted, so that construction can easily bypass the underground pipeline some obstacles. (3) horizontal directional drilling construction when crossing the river bed under generally 9-18 meters in depth, and the city is also deeper than 3 meters, hence the construction does not disfigure their surroundings and to meet the state's environmental protection Claim. (4) When using the device does not affect the construction of navigable rivers, its supreme launching operations, and therefore will not damage the riverbed structure, and a high success rate, short construction period, the construction, but also reduces the amount of construction personnel tasks . (5) low construction cost, the construction can be adjusted along with you, because in the formation deep inside, therefore avoiding oxidation, corrosion phenomenon occurs. Of course, in addition to Dongguan Shenlong horizontal directional drilling construction manufacturers can provide you with more information related to horizontal directional drilling, welcome to consult the discussion. Dragon trenchless drilling rig designed for trenchless engineering machinery, manufacturing machinery trenchless preferred Dongguan Shenlong. Trenchless drilling rig in the use of what steps to request? Here, we have for you a brief introduction. First, before using trenchless drilling rig to ensure the site has been a good survey, and construction of the venues ready; secondly trenchless drilling rig started working, horizontal directional drilling rig manufacturers, installation and connection-oriented and to ensure the probe drill battery can stick around long enough time, and checking whether the probe emission parameters and technical parameters given consistent. Trenchless drilling rig low, slow speed propulsion methods to promote and ensure the accuracy of the drill angle. If you need to adjust the angle of the drilling process, it is necessary to adjust the angle of the drill tool angle given for consistent, so the angle of the drill pipe out of the actual and technical parameters can not be given the perspective of a large gap. When straight drilling, trenchless drilling rig to maintain a constant speed rotation, and remained stable, horizontal directional drilling supply, ensure the pipe straight. When the guide hole construction is completed, should be pulled back reaming, in pulling back reaming process, the diameter of the aperture designed to be moderate, to be classified reaming reaming, trenchless horizontal directional drilling based on actual data, but also reinforcement of the hole wall, pull back guarantee should not exceed the limits of tension in the pipe conduit is pulled back. Trenchless drilling rig during these tasks, substantially all of the construction steps will almost done.
