With the increasingly complex urban underground space and rising environmental protection requirements, traditional trenching pipeline construction methods are facing severe challenges. As a mature trenchless construction technology, Horizontal Drill Rig enables the efficient laying of various pipelines through precise underground directional drilling without damaging the ground surface or affecting traffic and social activities. This technology has become a key equipment for modern underground engineering construction in municipal administration, energy, communications and other fields, providing reliable technical support for sustainable urban development.【WhatsApp/WeChat/Phone】+86 13837122632

The Working Principle of Horizontal Drill Rig
The construction of a standard horizontal drill rig is mainly divided into three precise stages: First, pilot hole drilling, where the drill bit advances along the designed trajectory under the guidance of a navigator; second, pre-reaming, where the hole is gradually expanded to the required size according to the pipeline diameter; finally, pipeline pullback installation, where the pipeline is connected to the reamer and pulled into the formed hole in one go by the powerful pullback force of the main engine to complete the entire laying operation.
6 Advantages of Horizontal Drill Rig
Compared with traditional trenching, the adoption of advanced horizontal directional drilling equipment can bring revolutionary improvement to project benefits:
- Environmentally friendly: It truly achieves “trenchless construction”, without damaging roads, green spaces, vegetation and existing building structures, making it particularly suitable for construction in protected areas and downtown districts.
- Minimal social impact: The construction process hardly hinders traffic or disturbs citizens’ normal lives and commercial activities, greatly improving the public acceptance of municipal engineering projects.
- High construction precision: Equipped with advanced guidance and monitoring systems, it can adjust the drilling direction and depth in real time, accurately bypass existing underground obstacles, and the laying precision is far higher than that of manual trenching.
- Lower comprehensive cost: It eliminates the need for large-scale excavation and backfilling, significantly reducing earthwork volume, road restoration costs and labor costs, and shortening the project cycle by 30%-50%.
- Longer pipeline service life: Pipelines can be buried in the deep and stable crust (usually 6-18 meters), avoiding the impact of surface activities, corrosive substances and temperature changes, thus naturally extending their service life.
- Wide application range: It can adapt to various stratum from soft soil to hard rock, cross complex obstacles such as rivers, railways and highways, and accommodate a large range of pipeline diameters, making it a truly multi-functional construction platform.
Where Is a Directional Boring Machine for Sale Needed?
You should consider purchasing a reliable horizontal drill rig when your project is faced with the following scenarios:
- Key obstacle crossing: It is necessary to cross underneath expressways, high-speed railways, river dikes or the foundations of important buildings.
- Sensitive area construction: Pipeline laying or renewal is carried out in historical and cultural relics protection areas, ecological wetlands, mature crop fields or densely populated downtown areas.
- Deep-buried pipeline projects: Oil and gas pipelines, high-voltage cables, main water supply pipelines and other facilities need to be buried several meters or even more than ten meters underground to ensure their long-term safe operation.
- Emergency repair and capacity expansion: Old pipelines are repaired or new pipelines are laid in parallel without stopping transportation or closing roads.
Performance Factors Affecting Horizontal Drilling Machine Price
The price mainly depends on the following configurations:
- Push-pull force and torque: These are the core parameters determining the equipment’s crossing capacity and applicable pipeline diameter. The greater the pullback force, the longer and larger-diameter pipelines can be laid.
- Power and drive system: Engine power and power head torque directly affect drilling efficiency, especially in hard rock formations. Hydraulic motor-driven push-pull systems usually provide more stable and powerful output.
- Automation and intelligence level: Functions such as automatic drill pipe handling system, adaptive stratum control and electric shock protection system will increase the initial investment, but they can greatly improve construction safety and efficiency, and reduce long-term operation costs.
- Mud system performance: A high-flow and high-pressure mud system is the key to maintaining borehole wall stability and discharging drill cuttings, which is crucial for construction in complex formations.
