The underground pipe drilling machine also named horiztontal directional drilling machine, is a piece of equipment specifically designed to drill holes or tunnels underground to install pipelines. It quickly drills holes in the ground by drilling to lay pipes underground. By minimizing surface disruption, underground pipe boring machines are ideal for projects in urban areas where minimizing damage to existing infrastructure, traffic disruption, and environmental impact is critical. They are available in different sizes and configurations to meet a variety of pipeline installation requirements, from small-diameter pipes for residential plumbing to large-diameter pipes for industrial and municipal applications.

Advantages of Trenchless Technology:
- Reduce surface damage: No need for large-scale excavation, minimize the impact on roads, green spaces, and traffic.
- Higher construction efficiency: Faster construction speed, shorter construction period, and reduced labor and time costs.
- Less environmental impact: Reduce dust, noise, and soil disturbance, more environmentally friendly.
- Reduce overall cost: Save excavation, backfill, road repair, and other costs, and reduce overall costs.
- Traversable obstacles: Able to cross obstacles such as rivers, roads, railways, buildings, etc. without destroying ground facilities.
- Higher safety: Reduce excavation operations and reduce safety risks during construction.
Widely Used Fields of Underground Pipeline Drilling Rigs:
- Municipal water supply and drainage pipeline laying: New construction and renovation projects of urban water supply pipelines, drainage pipelines, and rainwater pipelines.
- Petroleum and natural gas pipeline engineering: The laying of long-distance oil pipelines and gas pipelines across rivers, mountains, cities and other complex areas.
- Communication optical cable and cable engineering: The underground laying of urban communication optical cables and power cables is especially suitable for urban central areas to reduce the impact on traffic and cityscape.
- Heat pipeline engineering: The laying of urban centralized heating pipelines to achieve non-excavation construction of heat pipe networks.
- Crossing engineering: The laying of pipelines and pipelines across obstacles such as rivers, lakes, railways, roads, and buildings.
- Urban underground comprehensive pipeline corridor construction: The laying of various pipelines in the urban underground comprehensive pipeline corridor to achieve intensive management.
- Agricultural irrigation pipeline laying: The underground laying of farmland water conservancy irrigation pipelines to improve the efficiency of water resource utilization.
Working Principle of Underground Pipeline Drilling Rig:
- Guide hole drilling (guide drilling): Drill directly from the ground working pit or the ground, use the guide drill bit and the guide system to accurately drill a guide hole according to the pre-designed trajectory. The operator monitors the drill bit position in real time through the ground positioning system and adjusts the drilling direction to ensure the accuracy of the guide hole trajectory.
- Bore expansion (back expansion): When the guide hole is drilled to the predetermined position, it is replaced with the back expansion drill bit, and the hole diameter is expanded in the reverse direction along the original guide hole to provide sufficient space for subsequent pipeline laying. Depending on the pipeline diameter and geological conditions, multiple hole expansions may be required.
- Pipeline back pulling: After the hole expansion is completed, the pre-welded pipeline is connected to the back expansion drill bit, and the drill rod is pulled in the reverse direction again to drag the pipeline into the hole to complete the laying of the pipeline. During the back pulling process, the mud system continues to work to stabilize the hole wall, lubricate the pipeline, and reduce the back pulling resistance.
