In many construction fields that need slurry shield engineering, when the slurry outlet of slurry sump was blocked, the workers need to manually open the gate to reach the slurry sump for manual cleaning of foreign matters, which is called opening in construction. The shield machine needs to be stopped due to the long time and high risk of warehouse opening; if the geological conditions are bad, the foundation reinforcement construction needs to be carried out from the ground, which greatly increases the project cost. Generally, the opening operation takes 2-3 days. If the surface reinforcement is needed, the construction period will be more than 1 month, which seriously affects the progress of the construction period.
Aiming at the above problems, Craun provides a simple, safe, reliable, time-saving and efficient mud circulation treatment method in shield tunneling.
The Features of the System
1. Fully purify the mud, effectively control the performance index of mud, reduce the sticking Accident and improve the drilling quality. Large bearing capacity, safe and reliable.
2. Realize the circulation of mud and save slurry materials. Greatly reduce the cost of waste pulp transportation and pulping.
3. The third / fourth phase of separation can be adopted according to customer requirements to meet the reuse requirements.
4. Mud circulation and reuse reduce the impact on the environment and save the construction cost.
5. The system can run continuously to improve the construction efficiency.
6. The overall skid mounted design of the system has the advantages of small floor area, easy removal and maintenance.
