Gaodetec Equipment can provide high quality cement grout mixing plant to underground construction companies specializing in tunnel excavation, especially in tunnel excavation projects, where we need to install a grouting mixing plant for filling the annular void of the tunnel.
A grout mixing plant is a critical piece of equipment used in tunnel construction to fill the annular void between the tunnel lining (such as a segmental lining or shotcrete) and the surrounding ground. This process, known as annular gap grouting, is essential for ensuring the stability, waterproofing, and long-term performance of the tunnel.
Grout mixing plant for filling the annular void of the tunnel can be capable of mixing at a speed of 1500 rpm and has a usable capacity of 1 m³. A semi-open access hatch at the top be included. A discharge valve, as well as a connection for transfer to a buffer tank, can be provided.
1. Precise Mixing: The grout mixer plant must accurately mix cementitious materials (e.g., cement, bentonite), water, and additives (e.g., accelerators, retarders, water-reducing agents) to achieve the desired grout properties (e.g., viscosity, setting time, strength).
2. Consistent Quality: Ensures uniform grout quality to prevent segregation, bleeding, or inconsistent setting, which could compromise the grouting effectiveness.
3. Adjustable Parameters: Allows for real-time adjustment of mix proportions, flow rate, and pressure to adapt to varying ground conditions and project requirements.
4. High Output Capacity: Capable of producing large volumes of grout continuously to meet the demands of tunnel boring machines (TBMs) or other excavation methods.
