Characteristics of horizontal directional drilling construction
 Horizontal directional drilling rig is the mechanical equipment for laying underground pipelines without excavating the ground. It can successfully avoid obstacles within a certain radius underground, and can operate in clay, sand and other strata underground, and is widely used in the laying of flexible pipelines in the fields of electricity, communication, oil and natural gas.
 Unlike closing the whole road, digging and repairing, as we often see, horizontal directional drilling machines only need to be completed on the roadside, and will not affect traffic and people's normal travel.
 Through the advanced equipment calculation and positioning, the whole drill bit crossing process can bypass the obstacles to reach the predetermined position, and ensure the construction accuracy.
Horizontal directional drilling machine only needs to be completed on the side of the road, and will not affect the traffic and people's normal travel.
 How does the horizontal directional drilling rig work
 Before the construction of the horizontal directional drilling rig, the first thing is to confirm the position of the horizontal directional drilling rig and the position of the drilling mouth according to the construction drawings. Usually, these two points are in a straight line, and record the relevant coordinate data.
 Also the soil, water and additives and other raw materials into mud, through the mechanical mud pump into the drill nozzle, the function of the mud is mainly to cool the drill and reduce the friction of the drill, to avoid the occurrence of the drill jam phenomenon, the mud can be reused after recycling and filtration.
 The horizontal directional drill fixed in the drilling position, choose the right drill, according to the predetermined position and Angle, let the engine power for the drill, and drive the rotating drill rod drive the drill, drill work mud motor will continue to spray mud, drill through the ground obstacles, finally through the ground form guide hole.

 When the drill bit with the drill pipe out of the ground, will unload the drill, the drilling tool and the drill pipe installation, drilling tool diameter according to the size of the laid pipeline, start drilling operations, in the process of back, the drill rod rotation, the drill and drilling head back, back, eventually expand the diameter of the underground pipe.
 At the same time of reaming, the pipeline should be fixed behind the reaming tool. When the drill drags the drill pipe, it will take the reaming tool and the pipeline at the same time. Finally, the pipeline will be dragged off the ground around the ground obstacles and off the ground to complete the laying of the whole pipeline.
In the process of reaming, reaming tools should be selected according to different soil layers. The soft soil layer only needs to choose the reaming type, such as the soft rock or hard soil layer, the reaming with pulley or hob, and if there is a rock layer, the reaming with cutting and discharge function.
