Grouting pump with mixer for pipe jacking project

Grouting pump with mixer for pipe jacking project

Grouting pump with mixer for pipe jacking project is a complete set of equipment that combines a mixer, a pulper and a grouting pump to perform efficient and low-consumption work, effectively reducing complex procedures and remote operations. The pulper performs high-speed pulp production and storage of cement slurry and similar materials, and then directly pumps the slurry to the construction connection point with a pump to complete the uninterrupted slurry injection.

WGP400/700/80PL-E grouting pump with mixer is an all-in-one machine, high-shear grouting mixer, agitator, grouting pump all concentrated in one device, very easy to operate and move, able to perform efficient and low-consumption work, Effectively reduce complex procedures and remote operations. WGP400 / 700 / 80PL-E grouting pump with mixer for pipe jacking project is specially designed for pipe jacking project. The volume of grouting mixer is 400L and the volume of agitator is 700L. The pressure is divided into two stages, namely low pressure stage and low pressure stage , The low pressure stage is 0-25 bar, the grouting flow is 0-80L / the minimum pressure in the high pressure stage is 45 bar, and the flow rate is 0-58L/min.

The role of grouting pump with mixer in pipe jacking project:

Because the diameter of the tunneling machine in tunneling engineering is generally 2-5cm larger than the diameter of the pipeline. Due to the difference in diameter of the pipe, there is a gap between the pipe and the surrounding soil. Grouting pump with mixer will now fill the gap between the pipes with mud injected from the grouting hole. Under pressure, the mud contacts the soil and penetrates into the soil layer, slowly spreading out, and forming a whole with the surrounding soil. With the increase of the infiltration volume, the soil body and the mud will form a dense layer of permeable blocks. At the same time, under the effect of the mud pressure, the blocks are closely combined, so that a stable mud and soil are formed around the pipeline The "mud sleeve" composed of the body. The formation of this mud jacket prevents the mud from continuing to penetrate into the outer soil layer. At the same time, the mud will flow under the pipeline under the action of the mud pressure. When the mud jacket is formed around it, it can support the surrounding soil body to play a buoyant role.

WGP400/700/80PL-E grouting pump with mixer for pipe jacking project adopts electric drive, strong power, small volume and light weight, suitable for a wide range of construction. It can be used safely even in flammable and explosive construction sites such as coal mines. Grouting pump with mixer is widely used for grouting and blocking water in tunnel and mining face; grouting for rock roadway and concrete shaft wall to block water leakage; tunnel cracks, broken rock mass, evacuation rock reinforcement; anchor grouting; backfilling grouting and preventing the surface from sinking, preventing landslides, correcting the deflection of buildings, etc.
