This app is targeted to all Tunnel Boring Machine operators around the globe, using in particular the "Pipe Jacking" method, and for the job site management teams.
After you input the required values and press "Calculate", it will show the operator the total amount of bentonite he will use for the drive for lubrication purposes, and at what speed he should be pumping it at as he is advancing the TBM.
Job site management can use it to calculate in advance how much bentonite will be required for the drive/project.
