Sprayed concrete equipment

 

 

Sprayed Concrete portable pump features

 

Main features

Rigid monoaxle trailer with drawbar 4 manual adjustable outriggers and 2 rubber wheels.
Suitable for transit on the job-site with the speed 6 km/h
The unit is not prearranged with lights and brake systems.
Power source consisting of a separate engine (Diesel or electric). Main pump of axial piston type with variable capacity and constant power. Gear pump for auxiliary services.
The machine is prearranged for the pumping unit of PCS6" Series with “S” valve in wear-resistant casting iron, longitudinally placed on the chassis. A wear ring is mounted between the eye-plate and valve, for a perfect seal, assuring the stiff pumping of the sprayed concrete. CIFA system tackled with the compensation ring which allows avoiding annoying adjustments.
The equipment is presetted to use the new proportional batchers "Silicaflux", suitable for liquid or powdered accelerators with density from 3% to 20%. The batcher is automatically connected with the sprayed concrete pumping system. Consequently, by varying the sprayed concrete pumping output, the accelerators quantities are adjusted automatically, keeping the batching ratio pre-set by the operator.
• Transportability and practicability on the job-set
• Integration and flexibility
• Safe and ergonomic
• Quality and reliability
• Low operating costs and scheduled maintenance

Guniting is the method of concrete mixture application on the concrete surface in layers under compressed air pressure. Under this method solution is applied and concrete mixture is splashed by grouting machine under compressed air pressure on the construction’s surface as a shotcrete. Grouting machine is been constantly loaded with dry sand-concrete mixture and pumping distance is upwards to 70 m. Shotcrete is characterized by high density and water resistance.

 

The sprayed concrete is applied when:

• Versatile technology of concrete application on the building constructions under heavy pressure in order to get high quality concrete at restoration work hydrotechnical and other objects.

• Batter&bias Protection. The operation life of the latter is increased thanks to crack absence. Onlay thickness can be diminished as the shotcrete bears against to the earth & rock base circuit. Shotcrete onlay is distinguished by superior durability under deformations, better loading and tension distribution compared with simple concrete onlay

• Upkeep and recovery of hydrotechnical constructions. New upkeep technique for concrete constructions by shotcreteing with wire cloth is applied for dam, sluices, cooling stack, embankment, bridge and other constructions building. The hydrotechnical constructions renovation allows to reduce the number of workers and operations and to finish work faster during the navigation. The sewage culvert constructions and restoration can be performed from within, without uncovering the duct and excavations.

• The building restoration damaged by earthquakes and others unpredictable charges. The shotcrete of high density, applied under heavy pressure, possesses other advanced exploiting features, including higher resistance against wearing power, corrosion, weathering. Contraction is also lower.
