Gaodetec squeeze pumps (APP) used for tunnel boring machine (TBM) and bentonite slurry and transfer. Here they are ready to ship to the client.

At Gaodetec we take complex project needs and build systems and equipment that simplify the Slurry mixing process. Our customer need a squeeze pump solution for this project. Project requirements are as follows:

Tunnel Boring Machine (TBM) grout feed pump:

The grouting process used for this project will be a two component “A” & “B” grout.

Grout will be water, cement, flyash, bentonite and liquid stabilizer. S.g. 1.3% solids by weight 36%. Flow rate variable up to 378 litres / min (100 gpm). Discharge pressure variable up to 2.5 Mpa (360 psi).

Bentonite Slurry & Transfer:

The bentonite squeeze pump is used as a backup pump for the tunnel boring machine feed pump, which also transfers bentonite to TBM and delivers the hydrated bentonite to the grout mixer to suit the selected mix design.

Bentonite slurry mixed at 8% with a batch content of approximately 235 litres (62 usg).  Pump flow @ 378 l/m (100 gpm) time to transfer bentonite slurry to grout plant approx = 37 seconds depending on cycle time requirements.
