How to Solve Shield Tunneling Clay Dispersion Challenges? Chemi Tech's Professional Solution Boosts Efficiency

During shield tunneling construction, challenges posed by clay layers often trouble engineering teams. Clay tends to form lumps and adhere in front of the cutter head and within the soil chamber, leading to poor soil discharge, increased tool load, and even triggering停机清理. This not only severely impacts施工进度 but also increases equipment wear and maintenance costs.

Chemi Tech has deeply understood this industry pain point and developed a targeted shield tunneling clay dispersant solution. The core of this solution lies in chemically modifying soil properties, disrupting the bonding force between clay particles, making them easy to disperse and flow after excavation, thereby ensuring smooth discharge.

Our solution specifically involves three steps. The first step is on-site soil sample analysis, evaluating clay type, water content, and plasticity index to provide precise basis for agent selection and dosage. The second step is custom formulation, where Chemi Tech technicians tailor appropriate dispersant combinations based on analysis results to ensure compatibility with现场水土条件. The third step is injection and monitoring, during the shield tunneling process, the dispersant is掺入土仓或刀盘前方 through a dedicated injection system at set ratios, with real-time monitoring of discharge status and equipment parameters, dynamically adjusting the injection strategy.

In a shield project for a city subway extension line, the construction section traversed thick layers of high-plasticity clay. Initially, cutter head torque异常升高, discharge ports频繁堵塞, and daily progress严重滞后. After implementing Chemi Tech's dispersant solution through the three steps mentioned, soil lumping现象显著减少, discharge became连续顺畅. Cutter head torque returned to normal范围, daily tunneling efficiency improved by approximately 30%, and tool inspection cycles were extended, restoring overall施工节奏稳定. The project party acknowledged the处理效果.

Chemi Tech's shield tunneling clay dispersant aims to help您化解 clay-induced construction obstacles, ensure smooth operation of shield equipment, and advance tunnel projects more efficiently and economically.
