customized grout pump with mixer for tunnel grouting

A high-speed grout mixer is a critical component in modern tunneling operations, especially for applications like backfill grouting, ground improvement, and sealing voids behind tunnel linings. When filling tunnels — particularly those constructed using Tunnel Boring Machines (TBM) or shielded tunnel boring machines — high-speed mixers ensure the rapid and consistent production of large volumes of pumpable, stable grout.

Grout mixer used for tunnel excavation application:
Ground Stabilization: Used to inject a stable grout mixture to improve the load-bearing capacity of weak soils and prevent ground settlement during tunneling.
Water Ingress Prevention: Essential for sealing voids and fractures in the rock formation to prevent water ingress, which can compromise the stability of the tunnel.
Rock Bolting and Anchoring: Grout is used to fill the spaces around rock bolts and anchors, enhancing their holding capacity and ensuring the structural integrity of the tunnel.
Void Filling: After excavation, grout is injected to fill voids and cavities, reducing the risk of collapse and ensuring a safe working environment.
Curtain Grouting: Creates a grout curtain around the tunnel to act as a barrier against groundwater, protecting the tunnel from water damage.

Customized High Efficiency Grout Mixing Pump can be adapted for various types of grout materials, including cement-based, epoxy-based, and polyurethane-based grouts. They can also be configured for different applications, such as foundation grouting, tunnel lining, and soil stabilization.
