BB variable grouting pump
The BB series double-liquid variable grouting pump for coal mines has a synchronous grouting function that plays an important role in the field of double-liquid grouting, especially in chemical grouting that requires instantaneous initial setting. Remarkable results. In the coal mine. It has excellent performance in subway, tunnel, bridge, metal mine and other projects. It can perform both single-liquid grouting and double-liquid grouting (cement, water glass).
The BB series double-liquid grouting pump has a graded grout ratio within the range of:~:.
The main models of this series: BB./-grouting pump, BB/-double-liquid variable grouting pump, B/-double-liquid grouting pump, BB./-variable grouting pump, BB../mine Use a double-liquid variable grouting pump.

Grouting design method:
. Determine by investigating surrounding rock characteristics Surrounding rock grouting range.
. Determine the permeability of the rock mass and determine the specific location, angle, depth, number of grouting rows, horizontal distance, and vertical distance of grouting.
3. Determine the specific requirements for the grouting test and detect the test results.
.Based on the experimental results, optimize the design of specific parameters and determine the grouting material and pressure.
The grouting method is suitable for reinforcing sand foundations, curtain grouting for dam foundations, water-stopping and leak-proofing in underground projects, and reinforcing muddy interlayers and fault fracture zones in dam foundations. There are many types of polymer chemical pulp materials, including epoxy resin, acrylamide (propylene condensation), polyurethane (cyanide condensation), lignin, etc. The commonly used polymer chemical grouting materials in foundation chemical grouting are acrylamide and polyurethane. Acrylamide slurry consists of the main agent acrylamide and various additives. The viscosity of the slurry is close to water, and the pourability is good. After the slurry is solidified, the gel is impermeable and has good durability and stability. This type of slurry is widely used in anti-seepage grouting of fine cracks in rocks, medium-fine sand layers and dynamic water leakage plugging projects.
