Efficient Dispersion Challenges in TBM Construction? Chemi Tech Offers Customized Adhesive Dispersion Solutions

In TBM tunneling through complex strata, common and troublesome challenges include muck adhesion to the cutterhead, formation of clay cakes, and inefficient soil discharge. These issues not only drastically reduce advance rates and accelerate equipment wear but also pose significant downtime risks, directly impacting project schedules and cost control. Traditional treatment methods often prove ineffective or costly, creating a market demand for efficient, reliable, and economical professional solutions.

Chemi Tech, with a deep understanding of these industry pain points and leveraging our expertise in specialty chemicals, has successfully developed a series of dedicated adhesive dispersants for TBM applications. The core of our products lies in their unique molecular design, which effectively penetrates and coats the surface of soil particles, significantly reducing inter-particle adhesion and internal friction, thereby fundamentally inhibiting adhesion and cake formation.

Our solution is not merely a product supply but a complete customized service system. First, our technical team conducts field surveys or analyzes geological reports to identify soil characteristics and construction difficulties. Second, we perform targeted formulation simulation and performance testing in our laboratory to select the optimal product type and dosage ratio. Third, we develop a detailed on-site injection plan, including injection points, flow control, and recommendations for synergy with existing foam systems. The fourth step involves dispatching engineers for on-site guidance and parameter optimization to ensure peak product performance. Finally, we provide continuous tracking service, dynamically adjusting the plan based on advance data and muck condition.

In an urban rail transit tunnel project in Eastern China, the contractor faced severe cutterhead cake formation when traversing a composite stratum rich in sticky minerals, requiring manual cleaning every approximately 20 rings, which severely delayed the schedule. After introducing Chemi Tech's adhesive dispersant, our team quickly determined a specialized formula based on rock samples. Following the implemented injection plan, adhesion on the cutterhead and within the chamber was significantly reduced, cake formation was virtually eliminated, and continuous boring capacity increased to over 80 rings without cleaning downtime. Muck discharge smoothness greatly improved, effectively safeguarding the project's critical timeline.

Choosing Chemi Tech means you gain not only a high-performance dispersant but also a partner committed to enhancing the smoothness and cost-effectiveness of your TBM operations. With our professional expertise and dedicated service, we help you overcome geological challenges and ensure efficient, steady project advancement.
