Diesel Horizontal Helical Drilling Rig

 

The BGD-160 guided spiral horizontal drilling rig is a new type of energy-saving, efficient and flexible and convenient underground pipeline laying drilling rig developed by our company.

 

This drilling rig adopts advanced optical navigation targeting technology. During the process of laying underground pipelines, it can precisely control the direction of pipeline laying, ensuring that the laid pipelines fully meet the pre-determined underground pipeline position and direction requirements.

 

Diesel horizontal helical drilling rig is mainly used for the precise laying of various municipal projects such as urban underground drainage pipes, underground heating pipelines, gas supply pipelines, water supply pipelines, and underground channels for various types of cables in cities. The positioning accuracy of its pipeline laying is not only precise but also does not affect ground facilities or ground traffic order. At the same time, it also plays an important role in projects such as the pre-support of pipe sheds for tunnel excavation and the reinforcement of pipe sheds for railway subgrades.

The diesel-powered horizontal helical drilling rig is a type of trenchless construction equipment widely utilized in applications such as underground pipeline installation and operations within environmentally sensitive areas.

 

1. Urban Underground Utility Construction

• Municipal Engineering: Used for laying water supply, drainage, gas, and power cable lines, avoiding destructive excavation of roadways and minimizing traffic disruption.
• Communication Fiber Optics: When deploying fiber-optic networks in densely populated urban areas or historic preservation zones, the method allows for bypassing underground obstacles (such as existing utility lines or building foundations).
• Advantages: High construction precision (guidance systems control both trajectory and depth) and suitability for complex urban geological conditions (e.g., soft soils, sandy strata).

 

2. Construction in Environmentally Sensitive Areas

• River/Lake Crossings: When laying oil and gas pipelines or cables, the method eliminates the need for damming or excavating the riverbed, thereby protecting aquatic ecosystems.
• Applications: Commonly employed in cross-river pipeline projects, such as the onshore extension segments of submarine cables.
• Nature Reserves/Agricultural Lands: Minimizes surface disturbance, preventing soil erosion and damage to vegetation.

 

3. Operations in Challenging Geological Conditions

• Loose Strata: The rotational thrust of the helical drill bit stabilizes the borehole walls, reducing the risk of collapse.
• Hard Rock Formations: When paired with mud motors or percussion hammers, the technique enables effective drilling through hard rock (e.g., shale, granite).
• High-Precision Requirements: Real-time guidance technologies (such as electromagnetic positioning) ensure that pipelines are laid precisely according to the designed trajectory.

 

4. Industrial and Energy Sectors

• Oil and Gas: Long-distance installation of oil and gas transmission pipelines, particularly in harsh environments such as deserts or permafrost regions.
• Chemical Industrial Parks: Safe installation of underground pipelines for hazardous materials, avoiding the leakage risks associated with open-trench excavation.

 

5. Emergency Repair and Renovation

• Aging Infrastructure Renewal: When replacing corroded pipelines, the method allows for in-situ borehole expansion and the simultaneous pull-through of new pipes, significantly reducing project duration.
• Disaster Recovery: Rapid repair of damaged underground infrastructure following earthquakes or floods, minimizing secondary damage to the surrounding environment.
