Dragon trenchless drilling rig designed for trenchless construction machinery Tianjin trenchless drilling, manufacturing of non-excavation machinery 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 to work, installation and connection-oriented and to ensure the probe drill battery can last long enough time, and inspection probe whether to transmit parameters and technical parameters given consistent. Trenchless drilling rig low, slow speed propulsion methods to promote accuracy in Tianjin trenchless drill angle drill, guaranteed. 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 drilling straight Tianjin trenchless drilling, trenchless drilling rig to maintain a constant speed rotation, and remained stable, 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 moderate, grade reaming reaming should be based on actual data, but also to reinforce the walls of the hole, in pull back guarantee should not exceed the limits of the pipe conduit pull pulled back. Trenchless drilling rig during these tasks, substantially all of the construction steps will almost done. Modern Trenchless technology is the use of rock-oriented, directional drilling and other means, in the case of the surface without trenching, laying, replacement or repair of all kinds of construction technology of underground pipelines. Significant social and economic benefits of the technology in Tianjin trenchless drilling, especially in laying the pipeline, such as crossing the roads, railways, buildings, rivers, heritage conservation district, downtown, crops and vegetation protection zone can not be implemented in some areas of excavation, etc. . The technology is now widely used in gas, telecommunications and power engineering sectors. Modern trenchless underground pipeline construction method have appeared in large numbers since the beginning of the 1970s, including: horizontal directional drilling, horizontal directional drilling, steerable horizontal auger, impact spear, Rammer, miniature by road, old pipe replacement and repair, Top of the boring machine.
