A construction project in Namibia required crossing a wide dry riverbed. The loose surface soil made it impossible for traditional large-scale construction equipment to operate, while the excavation scheme was not only costly but also highly disruptive to the environment. The HDD boring machine (Model YG-180) provided by YG, with its outstanding performance, became the key to solving this problem.【WhatsApp/WeChat/Phone】+86 13837122632

Customer Requirements
A local engineering contractor in Namibia undertook a livelihood water supply project. Its core challenges were as follows:
- Topographic and Geological Difficulties: The pipeline to be laid had to cross a wide dry riverbed. The surface soil was loose with extremely poor bearing capacity, making it impossible for conventional heavy machinery to enter and operate safely.
- Environmental Protection Pressure: The project owner required minimizing damage to the fragile riverbed ecosystem, avoiding soil erosion and changes to the river channel structure caused by excavation.
- Construction Efficiency and Reliability: Located in a remote area, the project demanded high equipment reliability, a short construction period, and one-time successful operation, so as to avoid rework and economic losses caused by faults such as borehole collapse.

Why the Customer Chose Our Directional Drilling Machine for Sale
Faced with technical difficulties, the customer actively searched for solutions online and found our official website through the keyword “horizontal directional drilling machine for sale”, thus kicking off the cooperation:
- Efficient Initial Inquiry: The website customer service responded promptly. After initially learning that the project involved “riverbed crossing” and “soft geology”, they immediately transferred the inquiry to a senior product manager.
- In-depth Technical Communication: The product manager conducted multiple rounds of in-depth communication with the customer, analyzed the riverbed geological report, crossing length and pipe diameter requirements in detail, and explained how trenchless technology perfectly met their needs for environmental protection and high efficiency.
- Solution Focus: Based on a comprehensive assessment of the working conditions, we quickly focused on the HDD boring machine series, which is suitable for medium and long-distance crossings with strong adaptability.

How YG-180 HDD Boring Machine Overcame Construction Challenges
In view of the particularity of the Namibian riverbed project, we recommended the YG-180 model. This equipment provided a perfect solution in various aspects:
- Balanced Compact Design and Powerful Performance: With a moderate overall dimension (640022702340mm) and a weight of 8500kg, the machine is easy to transport and has better adaptability to soft ground. Meanwhile, it delivers a maximum thrust/pull force of 180KN and a torque of 6000N.m, ensuring sufficient power for long-distance crossings.
- Excellent Mud System: Its mud flow rate of up to 250L/min and mud pressure of 80bar are specially designed for stabilizing loose and collapse-prone formations, effectively forming a solid mud cake with remarkable borehole wall protection effect.
- High-precision Guidance Control: Equipped with accurate guidance and monitoring capabilities, the machine can drill precisely along the designed trajectory under the riverbed, easily meeting the burial depth requirement of 6-18 meters and avoiding the unstable surface layer.
- Automation and Safety: The automatic drill pipe handling and connection lubrication functions reduce on-site manpower demand and improve operation efficiency in remote areas. Safety systems such as electric shock prevention ensure the safety of both operators and equipment.
- Environmental Friendliness: The entire construction process is carried out completely under the riverbed, without damaging the surface vegetation and structure, perfectly meeting the customer’s environmental protection requirements.

Practical Benefits Brought by Directional Drilling Machine for Sale
After the project was completed, the customer spoke highly of the performance of the YG-180 HDD boring machine:
The equipment’s performance in the soft riverbed working condition exceeded our expectations. The powerful mud system was the key to success, and the borehole wall remained stable throughout the process.
Compared with the traditional excavation method, this horizontal directional drilling machine for sale not only saved a huge amount of costs, but also shortened the construction period by nearly 40% with zero environmental disturbance.
