Trenchless Mud Purification Equipment: Rhino Industrial’s High-Efficiency Multi-Scenario Solution

In the trenchless construction sector—including horizontal directional drilling (HDD), slurry-balanced shield tunneling, and pile foundation boring—mud serves as the core medium to ensure smooth operations. However, sand-laden slurry generated during these processes, if left untreated, can lead to environmental pollution, increased costs, and operational risks.

Rhino Industrial’s trenchless mud purification equipment is specifically developed to address these challenges, focusing on high-efficiency purification, cyclic reuse, and scenario adaptability, and has become a key piece of equipment across various trenchless construction projects.

1. Core Requirements for Mud Purification Equipment in Trenchless Construction

Trenchless construction involves diverse scenarios and complex geological conditions (such as sand, clay, and gravel layers), placing three core demands on mud purification equipment:
Efficient impurity removal: Quickly separate cuttings of different particle sizes to prevent impurities from compromising the mud’s suspension and lubrication performance.
Flexible adaptability: Equipment must function effectively in confined urban construction sites as well as in complex outdoor environments.
Cost control: Enable mud recycling to reduce the procurement of new materials and slurry disposal costs, while minimizing the risk of environmental non-compliance.。

2. Core Technologies and Advantages of Rhino Industrial’s Trenchless Mud Purification Equipment

Rhino Industrial has developed modular, customizable mud purification equipment tailored to multi-scenario trenchless applications, with several key technological highlights:

• Multi-stage purification system: The system follows a “shale shaker coarse screening + hydrocyclone sand removal + desander/desilter fine filtration” process, capable of separating particles ≥0.074 mm, reducing sand content in treated mud to below 0.5%. The dual-motor high-frequency shale shaker separates coarse particles 0.5 mm within 10 seconds, while the hydrocyclone achieves 98% sand removal efficiency. Fine sediment has a water content below 30%, meeting diverse construction requirements for mud cleanliness.
• Intelligent adaptive design: Equipped with a PLC intelligent control system, the device automatically monitors mud viscosity and sand content, using an intelligent mixing module to precisely add bentonite and treatment agents, restoring mud performance in real time. The modular tank structure is lightweight and easy to assemble, enabling relocation within 24 hours and reducing the footprint by 20–50% compared with traditional systems. This design adapts to urban pipelines, mountainous crossings, shield tunneling, and other construction scenarios.
• Stable and durable features: Core components (sand pump, hydrocyclone, shaker screens) are made of wear-resistant alloys and high-strength materials, providing excellent abrasion and corrosion resistance, with continuous operation failure rates below 2%. The electrical system meets IP54 standards for explosion-proof, dust-proof, and rain-proof protection, suitable for high-temperature, rainy, and dusty field conditions, ensuring long-term stable operation.。

3. Multi-Scenario Applications and Practical Value

Rhino Industrial’s trenchless mud purification equipment has been widely applied across various trenchless construction projects, delivering significant value:

Horizontal directional drilling (HDD): In gas and water pipeline crossings, the system ensures mud reuse rates over 90%. In one project, new mud procurement costs were reduced by more than 70%, and equipment investment was recouped within three months, while preventing slurry contamination of roads and soil.

Slurry-balanced shield tunneling: In urban metro shield tunneling, the system efficiently purifies high-sand-content slurry discharged from the shield, reducing the volume of waste transported offsite by 80%, minimizing environmental impact, and ensuring continuous shield operation.

Pile foundation construction: In bridge and high-rise building pile foundations, purified mud stabilizes borehole walls, reducing collapse rates by 40% and significantly improving borehole quality. Mud waste is minimized, saving over 500,000 RMB in a single project.

To date, the equipment has served over 500 trenchless projects nationwide, with customer feedback highlighting superior purification efficiency and adaptability compared to traditional systems, making it a standard essential tool in trenchless construction.

Conclusion
Trenchless mud purification devices are a key component for improving construction efficiency, reducing costs, and practicing environmental protection. Black Rhino Industrial provides customized solutions for various trenchless construction projects through scenario-based technological innovation. In the future, Black Rhino will further integrate intelligent and energy-saving technologies to drive the development of trenchless mud purification devices towards greater efficiency, environmental friendliness, and convenience, contributing to the high-quality upgrading of the trenchless industry.
