How does grouting unit work
Grout unit could be matched with other machines, and doing the micro-tunneling grouting jobs. grout cement plant for tunnel boring machine has delivered some grout plant to the world famous tunnel builders, and help do the most significant ground anchoring, soil nailing, micro-piling, and post-tensioning grouting jobs.
How does grouting unit work?
Motors for hydraulic grout unit can be reciprocating,placed between the pistons as shown, or can be separate, operating the piston directly or through a mechanism. Air, hydraulic, electric, or internal combustion motors can be used. However, in order to get the variable outputs needed, motors that give a constant speed, such as electric and some internal combustion motors, must have variable-speed drives between them and the pump.
The grout unit for tunnel boring machine combines the latest technology of glue grouting and has a compact design. Water and solid materials are stirred at high speeds with a rotation speed of up to 1500 RPM to prevent solidification and achieve complete wetting of the particles.
