How about the orientation system of the Horizontal Directional Drilling Machine

guidance system

Guidance systems include wireless guidance systems and wired guidance systems. The wireless guidance system consists of a hand-held surface detector and a probe mounted in a drill bit. The detector judges the depth of the drill bit, wedge inclination and other parameters by receiving the electromagnetic wave signal emitted by the probe, and synchronously transmits the signal to the console display of the drilling rig, so that the driller can adjust the drilling parameters in time to control the drilling. When crossing rivers and lakes, because the ground is difficult to walk or the drilling depth is too deep, it is difficult to receive electromagnetic wave signals, so a wired guidance system must be used. The probe is connected to the cable through the drill pipe to transmit the signal to the operating platform. Since the cables must be manually connected through the drill pipe one by one, the use of the wired guide will be quite time-consuming.
mud system

The mud system is an important equipment to ensure the smooth progress of reaming and pipe pullback. After bentonite, water and additives are fully mixed in the mud tank, pressurized by the mud pump, sprayed out from the nozzle of the drilling tool through the drill pipe, scours the soil layer and takes away the cuttings, which plays the role of auxiliary drilling. Drilling mud cools downhole drilling tools to prevent them from overheating and wearing out. Another important function of drilling mud is to reduce the friction between the pipe wall and the hole wall when pulling back the pipe. In an ideal state, the pipeline is suspended in the mud and pulled out, so in actual engineering, if the drilling is well formed, the required pulling force for the pipeline is often much smaller than expected. The hole diameter of Horizontal Directional Drilling Machine is generally relatively large, and the stability of the hole wall is poor. However, after the drilling mud solidifies, it can stabilize the hole wall.

Intelligent assistance system

The intelligent auxiliary system of drilling rigs has developed rapidly in recent years. After pre-inputting the parameters such as the location of underground pipelines and obstacles, the type of drill pipe, the drilling depth, the location of the inlet and outlet, and the allowable bending radius of the pipeline, the drilling planning software can automatically design an ideal path, including the entry angle, exit angle, The specific position of each drill pipe, etc., can be adjusted according to the actual situation in actual engineering.
