High-pressure water tunnels

In hydroelectric power plants, shotcrete is

used for the stabilization and lining of

high-pressure water tunnels leading from

the water supply dam to the turbines of

the power house

Stabilization of slopes

Due to its sheer resistance and

good adhesion to the rock,

sprayed concrete strengthens the

substrate, by filling holes and

cracks and avoiding mud orm

rockslides

Underground mining

Progressive replacement of wire mesh

PLANT


Mechanized wet-mix spraying is the most efficient method for projects with high shotcrete production.

It is primarily applied for underground works in order to increase operator safety.

The concrete is introduced into the hopper of the concrete pump and transported through the

concrete line to the spraying nozzle, where it is mixed with compressed air and accelerator to be

sprayed on the substrate.

The SPM 4210 WETKRET has a

vertical spraying reach of 10 m

and concrete flow of 20 m3/h. The

dual cable and wireless

proportional remote control

permits easy handling of arm

movements, besides regulation of

the concrete flow and adjustment

of the additive dosage. With state-

of-the-art axles and a reinforced

turning system, the chassis is

ideal for the rough working

conditions in mining.

of 10 metres and the other of

7.5 metres, and a concrete flow

of 20 m3/h. Its compact size

makes its idea for small

galleries and reduced turning

radiuses, while its robust

chassis is ideal for underground

mining.

Work outside the danger zone

As all equipment components

are operated by remote control,

the operator can work from a

secure area that already

disposes of the required support

to prevent falling rock.

Safety in underground construction with mechanized

shotcreting equipment




Mechanized shotcrete

equipment requires fewer

operators than manual

application, which implies fewer

people working in areas of major

risk.

Fewer workers at the excavation face


The spraying arm allows

shotcrete application beyond the

manual spraying

reach, without scaffolding and

platforms that imply the risk of

falling down or getting hit.

Maintain your feet on the ground




The working lights of the

concrete spraying equipment

provide a synchronized

illumination with the application,

whereas manual application

requires external illumination.

See better




The mechanization improves the

working conditions by reducing

the physical effort of the operator

and the exposure to dust and

rebound.

Work in a healthier way




Being exposed to less stress, the

operator is able to concentrate

fully on his work, which leads to a

higher quality shotcrete support

and therefore improves security.

Obtain higher quality support




The low profile concrete mixers Putzmeister MIXKRET 4 y MIXKRET 5, and the underground batching

plant Batchkret 20 have been designed and developed to complete and optimize the shotcrete logistics.

Concrete logistics


The low-profile concrete mixers for

mining are designed to complete

the concrete spraying process.

The concrete mixing drum has a

maximum concrete capacity of 4 or

5m3, and the 6-cylinder, 130 kW
