Non-excavation machinery - Examples of Dongguan Dragon Trenchless Engineering Analytical Mechanical Technology Co., Ltd. of Dongguan City Shenlong trenchless technology uses conventional drill guide tube method, the following Minghe east jacking project examples detail oriented drill pipe technology. Project Overview Qijiang Dong Ming Bridge Crossing Project is located in the west of the west side of Zhongshan Dongming Bridge, crossing place at the east side of the bridge next the river, 38m from the south bank of the bridge buttress the position, width of 112m embankment between the two sides, the depth of 5m. Since Shiqi river was affected by the ebb tide, normal navigation channel need not be sealed route, therefore projects using directional drilling techniques to trenchless way gas pipeline crossing. The project is a φ273 × 9 pipe crossing, crossing the length of about 280m, the maximum penetration distance: natural ground below 10m; rig buried point in the south side, the point is located in Hebei unearthed side. Buried angle of 10 °, unearthed angle 6 °, drilling radius of curvature 488m. The project is a small cross, directional drilling technology has relatively low cost, short construction period, not blocking traffic, etc., with the continuous improvement process, which is kind of construction technology in pipeline gas, water, electricity and telecommunications sectors have begun widespread use. Dragon Main: Trenchless drill rigs, rig Trenchless small rotary drilling rig, drilling rigs change, trenchless drilling rig prices, trenchless drilling machines. Please call for more product information and ask price! Using trenchless directional drilling rig need to pay attention - specializing in the production of trenchless directional drilling rig non Excavation equipment used, many of my friends do not know its use, now you tell us about the dragon: Use trenchless directional drilling First, we need to pay attention to what explain the composition of trenchless directional drilling: it is a hydraulic pump driven by the engine, it has a drilling and rotation functions: engine power: Choose horizontal directional drilling, watching his continuous output power larger continuous output power to ensure that his work for a long time, but can extend the life of his two: Torque: torque and directional drilling mud flushing action is mainly depends on the process, the rig's output torque determines its maximum expansion Hole ability to determine the construction of the rig how three pipe diameters: drill size: horizontal directional drill rig is drilling rigs and the BHA most important power transmission link, its ability to rig a great finishing ability Influence bought trenchless directional drilling, trenchless pipe laying rig Dongguan Shenlong professional to provide you!
