The GSZ-8B dual-cylinder mixing and grouting integrated machine is also known as the vault mold-attached grouting integrated machine. It consists of two parts: mixing and grouting. The mixing part adopts vertical double-layer agitation, with the upper layer being the mixing tank and the lower layer being the storage tank. The grouting part adopts a dual-piston grouting pump. The grouting pressure and flow rate are automatically printed, enabling one machine to "conquer all," improving grouting efficiency and reducing the labor intensity of on-site workers.
Product Advantages
High pumping pressure, suitable for grouting low water-cement ratio and high-viscosity mortar.
Integrated mixing, storage, and grouting for convenient use.
The grouting pipe adopts quick-connect couplings, making it easy to disassemble and clean.
The pumping system uses mechanical coordination, which is safe and reliable, with few failure points and easy maintenance.
It can grout slurry with a large cement-sand ratio and a wide range of sand particle sizes.
Compact structure and flexible movement, especially suitable for confined workspaces.
To facilitate tunnel construction, the pump process has been upgraded to improve grouting quality.
Grouting one secondary lining plate takes only about 2 hours and does not occupy the normal construction time of the secondary lining.
Mold-attached grouting can begin when the concrete initially sets, and the grouting pressure is much higher than the grouting pressure after demolding, improving the integrity of the lining concrete and the grouting slurry and repairing concrete defects.
