WHAT ARTUSA DOES?

1. Shotcreting Works

Shotcrete is a process in which concrete is carried through a hose/pipe and sprayed pneumatically. The sprayed material when applied to the surface, fills the cracks and fissures, provide resistance to lose material from slope from falling. Shotcrete serves only as protective layer on the slope surface.

The shotcreting process is carried out form the base of slope to upwards so as to reduce rebound rate during the application of shotcrete on the surface.

The stabilization scheme for stabilization of slope using shotcrete can be designed and used with or without steel mesh. Design of shotcrete depends upon the purpose of project, design life, rock/soil strata.

There are two types of Shotcrete:

1.1 Dry-Mix Shotcrete

The cementing material and aggregate are mixed in proper proportions, transported in a dry condition and are transported right to a pneumatically operated gun to deliver a continuous flow of material through the supply hose to the nozzle. The nozzle’s interior is fitted with a water ring which uniformly injects water into the mixture as it is being discharged from the nozzle over the receiving surface.

1.2 Wet-Mix Shotcrete

The cementing material, aggregate, water and admixtures are properly mixed similar to what is done for conventional concrete. The mixture of material is supplied to the delivery equipment, like a concrete pump, which pushes the mixture through the delivery hose by positive displacement or by compressed air. Supplementary air is added at the nozzle to escalate the nozzle discharge velocity.

2. Slope Netting Works

Slope netting is used extensively on unstable rock faces and slopes to contain and control rockfall, protect against the effects of erosion and when combined with other methods, to improve stability.

2.1 Passive Slope Protection/Netting (Drape)

In a basic installation, netting is used to contain loose material and control erosion where it is often fixed as a drape anchored at the top and bottom. This allows loose material to be either safely trapped behind the netting or fall harmlessly behind the netting to ground level. Slope/Rock netting drapes are frequently used as fast but temporary solutions.

2.2 Active Slope Stabilization (Protection/Netting)

By the calculated use of anchors, dowels, rock bolts and tensioned cable strapping, slope netting can be tightly contoured to the rock face such that potentially unstable rock units are restricted from failing and an even stabilizing force can be placed into the slope. To do this well requires skill and experience. Artusa prefers to install slope netting in this option whenever possible, since fewer maintenance costs and increased safety levels.

3. Rockfall Barrier Works

For The Most Valuable Asset In Life: Our Safety

The danger of rockfalls is increasing due to climate change. This affects not only mountainous regions but also growing urban areas located close to rocky slopes. In order to provide the greatest possible safety at these locations, we have developed our barriers using high-tensile steel wire mesh. Despite the possible high impact energies of up to 10000 kJ we are able to keep the anchoring forces very low thanks to our unique system design. This combined with an easy installation make our barriers an extremely reliable and economical protection solution.

We Can Provide You With The Complete Safety Package

At your request we can take on the role of consultant, planner and even project manager. Both the solutions we offer and the quality of our customer service is valued by our customers. For us excellent service is an integral part of every single project. No matter which phase of the project you are in, we will provide you with the support and expertise required to achieve the best results – saving you both time and money.

Pros and cons

Cost efficiency

Quality You Can Rely On.

Our Barriers are remarkable because of its cost efficiency while at the same time meeting the strictest safety standards. The low weight and low anchoring forces of this series enable a quick and inexpensive installation. Our meshes are made of high-tensile steel wire, ensuring the lowest weight-to-strength ratio to achieve high stability. This is why our systems are particularly unobtrusive in the landscape.

We Don't Leave Safety To Chance.

All our systems are developed in Switzerland. They are tested under the supervision of and in cooperation with research institutes and certification bodies – using test facilities including the world's first for the rockfall barrier approval tests. Our customers can be sure that our barriers meet the highest standards.

Tested the most demanding way: vertical, free fall

All energy categories are approved in accordance with European Directive ETAG 027

4. Rock and Slope Scaling Works

Rock scaling generally refers to the removal of loose rocks or blocks on a slope but also includes the removal of loose debris as well as bushes and trees. This process is done by removing loose surface material presenting a rockfall hazard, usually with pry-bars and similar hand tools. Where large sections of rock or large boulders require removal, a variety of techniques can be utilized including winching, airbags or pillows, and breaking up in situ using power tools. Rock Scaling is safest and most effective when done considering rope access techniques. It is generally the first step in all rock stabilization jobs to make it safe to proceed with drilling or other required stabilization measures. However, scaling can be an individual slope stabilization measure as well. Nevertheless, it is often performed as an initial process in a slope stabilization project, as rock scaling alone is considered a temporary solution. Manual rock scaling is superior to mechanical or demolition scaling because it addresses individual rocks and does not destabilize the entire slope. However, trim blasting can also be used to remove larger rock features or mass.

Scaling is usually required on rock cuts above highways, railways, walking trails, hydropower plants, on high walls of open-pit mines and quarries, and on other structures. Some slopes require regular scaling, while others may be good for many years after a thorough scaling. Certain slopes may be stabilized through scaling alone, while others may require more extensive stabilization measures such as rock bolting, slope mesh netting, blasting or shotcrete.

Our use of rope access techniques as well as certified rope access technicians is how we increase safety. Each technician should be trained in rope access and rope rescue and is equipped with the necessary equipment to perform a rope rescue in case of emergency. Artusa employs some of the best rock rope access technicians in the industry and can respond to emergency situations asap.

5. Suspension Walk Ways & Foot Bridges

Suspension walkways are light structures that offer new routes for pedestrians and bicycles plus adding a particular touristic value to the area. Designed for environmental integration, they are ideal solutions for crossing rivers and valleys as well as for overcoming topographic difficulties.

Artusa has a multidisciplinary team of engineers and technicians to calculate and devise a custom project based on our own models or in collaboration with other companies, also taking into account which will be the optimal installation system according to the location of the footbridge.

With the commissioning of a new project, in our technical department we carry out an executive design of the elements, analyze the options of connection and transmission of the loads from the main cable to the ground, we look for the best connections of the main cable with the platform and the suspension hangers and, finally, we work with care the aesthetics aspects of the bridge so that it results in a structure that integrates and adds beauty to the space where it is located.

With the approval of the design, in our workshop we prepare the structure and manufacture the components of the suspended bridge. From the in catalogue parts to the special production of project parts, we are able to produce and assemble all gateway components in accordance with current EU regulations and the regulations of the country where it is installed. In Artusa,  we are experts in cable and we work with all the existing range in the market. We know this material, its properties and the ideal typology to get the best performance according to the needs of the project.

Finally, we install the bridge with our own and/or partners equipment or we supply all the necessary components to installation companies such as cable-pendulum and pendulum-structure junction clamps and rigid or flexible steel pendulum.
