Horizontal Directional pipelaying rig technical limitations trenchless pipe laying technology horizontal directional drilling rig limitations, directional drilling construction technique first used in alluvial coastal areas across the United States, trenchless pipe laying horizontal directional drilling rig is now able to begin Coarse in complex geological conditions, gravel, moraine and rocky areas, etc. through the construction. The longest through the construction reached 6,000 feet, pipe diameter of 18 inches. Horizontal Directional pipelaying rig C, Advantage proved: horizontal directional drilling is minimal environmental impact construction methods. The technology also can also provide the best protection layer pipeline, and a corresponding reduction in maintenance costs, but will not affect river traffic and shorten the construction period, proved to be currently the most efficient and lowest cost through the construction method. Dragon Machinery Co., Ltd. of Dongguan City is a collection of horizontal directional drilling, trenchless directional drilling, more than ten years of quality! Because professional so trustworthy! 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 summarize its characteristics 2 hands trenchless drilling rig manufacturers, we hope to help you understand us. (1) Unlike the previous excavation and construction of the conventional art 2 hand trenchless drilling rig prices, horizontal directional drilling does not hinder buying second-hand in the construction of non-excavation drilling rig, will not affect the traffic, it will not destroy the vegetation and schools and Residents of normal life and work. The level of modernization (2) through the high precision directional drilling equipment, to meet the general design requirements, and laying direction can be adjusted such that certain obstacles can easily bypass pipeline construction under the earth. (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 m 2 hand-dig rigs, hence it does not disfigure the construction and the surrounding environment, meet state environmental requirements. (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. 2 hand-dig rigs | 2 hand-dig rigs | drilling rig brand which is better provided by the Dongguan City Shenlong Mechanical Technology Limited.
