Grout Equipment

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.

Electric power cement grout mixer operates on electricity, making it suitable for both indoor and outdoor use where electrical power is available. It eliminates the need for manual labor or fuel-powered engines, reducing fatigue and emissions. Electric power cement grout mixer is built with robust materials such as stainless steel, the mixer is designed to withstand the abrasive nature of cement and bentonite, ensuring longevity and reliability.

A colloidal cement grout mixer is a specialized type of mixing equipment designed to produce highly fluid, stable, and homogeneous grouts, especially for applications requiring fine particle dispersion, such as in soil stabilization, under-reaming, diaphragm wall construction, or chemical grouting.

While a grout mixer is not specifically designed for mixing bentonite, it can be used to do the job in some cases, especially when you need a large volume of the mixture. However, it is important to note that due to the specific properties of bentonite, it may be more effective to use a mixing system designed specifically for bentonite. These specialized equipment are better able to handle the high viscosity of bentonite and ensure a uniform mix.

Key Features of a Jet Grouting Triplex Pump:
High-Pressure Delivery: Jet grouting requires the injection of grout at very high pressures to effectively erode and mix the in-situ soil. A triplex pump is capable of delivering the necessary pressure, often in the range of 20 to 50 MPa (or higher, depending on the specific application).
Consistent Flow Rate: The three cylinders of the triplex pump work in a coordinated manner to ensure a consistent flow rate of grout, which is crucial for maintaining the quality and uniformity of the grout columns.
Durability and Reliability: Jet grouting pumps are subjected to harsh operating conditions, including abrasive grout mixtures and high pressures. A triplex pump is designed to withstand these conditions, with robust construction and high-quality components to ensure long-term reliability.
Adjustable Parameters: The pump should allow for adjustments in pressure, flow rate, and other parameters to accommodate different soil conditions and project requirements.
Efficiency and Performance: A well-designed triplex pump will offer high efficiency and performance, minimizing energy consumption and maximizing the effectiveness of the jet grouting process.

Jet grouting requires high-pressure pumps to inject grout at pressures typically ranging from 20 to 50 MPa (2900 to 7250 psi), depending on the soil conditions and desired grout column diameter. The pump must be capable of delivering a consistent flow rate to ensure uniform mixing of the grout with the soil.

The Jet Grouting Pump is a critical component of the jet grouting system, responsible for delivering the grout under high pressure. The pump must be capable of generating pressures in the range of 20-50 MPa to ensure effective soil erosion and grout penetration. The pump should allow for precise control of the grout flow rate to match the specific requirements of the project (e.g., soil type, desired column diameter).

Applications of high pressure cement grouting station: Soil Stabilization: Improving bearing capacity of weak or compressible soils. Groundwater Control: Sealing leaks in dams, tunnels, or basements. Structural Repair: Filling voids or cracks in concrete structures. Mining and Tunneling: Reinforcing rock masses and preventing water ingress. Foundation Underpinning: Strengthening existing foundations or correcting settlement issues.

Diesel jet grouting pump uses diesel engine as power source, which enables the equipment to work normally in remote areas without electricity supply or unstable electricity supply. It can generate enough pressure to achieve efficient jet grouting operation, usually reaching pressure level of tens or even hundreds of MPa, ensuring that the grout can penetrate deep into the cracks of the formation. It is suitable for various types of soil conditions, whether it is loose sand or hard rock, and the construction parameters can be adjusted according to the actual situation. Due to the changeable and harsh use environment, diesel jet grouting pumps are generally made of strong and durable materials and are strictly tested to ensure their reliability and long life.

It plays an important role in foundation reinforcement technologies such as jet grouting and grouting. The main function of this equipment is to accurately proportion and fully stir cement, water, and other additives to ensure the preparation of uniform slurry that meets construction requirements.

Jet grout mixing equipment is responsible for mixing cement and other additives with water to make a uniform slurry. This slurry is then transported to the injection pipe by a high-pressure pump and injected into the ground to mix with the soil. During the construction process, the jet grout mixer must continue to operate to ensure the consistency and uniformity of the slurry, which is crucial to achieving the strength and permeability required by the design.
