What equipment is needed during HDD construction?
Mar 03, 2025| 1. Horizontal directional drilling rig
Horizontal directional drilling rig is the core equipment of construction, which is used to provide power for drilling and pulling back. Its functions include guiding drilling, reaming and pipe pulling back. According to the construction requirements, the parameters such as the pulling back force, torque and drilling speed of the drilling rig will vary.
2. Drilling tools
Drilling tools are an indispensable part of the drilling process, mainly including:
Drill rod: used to connect the drill bit and the drilling rig to transmit power and torque.
Guide drill bit: with sensors for real-time monitoring of the drill bit position and posture.
Expander: used to gradually expand the hole diameter for laying pipelines.
Mud motor: provides rotational power for the drill bit.
3. Mud system
The mud system consists of a mud mixing tank, a mud pump and a mud pipeline, which are used to provide mud suitable for drilling conditions. The main functions of mud include chip removal, lubrication and wall protection.
4. Guidance system
The guidance system is used to monitor and control the trajectory of the drill bit in real time to ensure that the drill bit moves along the designed path. Common guidance systems include wireless and wired types.
5. Auxiliary equipment
Generator: Provides power for the drilling rig and supporting equipment.
Water tanker: Used to replenish the water source of the mud system.
Recycling system: Used to treat the mud generated during the construction process to reduce the impact on the environment.
6. Other equipment
Positioning instrument: Used to measure and record the position and posture of the drill bit.
Mixing system: Used to prepare mud.
Pumping equipment: Used to treat drainage during construction.
