Erdox Terra (dim. H310x360 cm approx. or H360x310 cm approx.) represents the quickest and safest solution for stabilization of landslide slopes, for the emergency consolidation of roads affected by surface landslides and for the reprofiling of slopes with debris-flow events.

It is a metal, pyramid-shaped structure, with light weight, easy to transport and quick to install.
ERDOX SINGLE ANCHOR FEATURES:
ErdoX structures are calculated by structural calculations performed in accordance with the provisions of the current technical standards for reinforced concrete and geotechnical works, in particular:

UNI EN 1993-1-1 “Eurocode 3” – Design of steel structures - Part 1-1: General rules and rules for buildings;
UNI EN 1993-1-8 “Eurocode 3” – Design of steel structures Part 1 – 8: Design of joints;
UNI EN 12385-4 “Steel wire ropes – Safety”;
EN 10204:2004 “Metallic products – Types of inspection documents”;
D.M. 22.03.2018 “Technical standards for constructions”.
Each solution should be meticulously assessed and verified according to the specific project requirements. All types of Erdox barriers have been subjected to both full size and experimental tests in order to optimize the material characteristics in the development of finite element models and verify the reliability of the results obtained using calculation softwares. Our technical staff is at your complete disposal to evaluate and recommend the best design solutions.
It is a metal structure, with pyramid-shape, low weight, easy to transport and quick to install. The velocity of the system is ensured by the fact that it requires connection to a single foundation, whether it consists of a prefabricated plate, supplied with the system, or a passive anchor made in situ.
Prefabricated foundation plate supplied with the ErdoX system. This solution consists of burying a steel plate of suitable size, so as to ensure that a resistant action is established, as a result of the load configuration acting on the barrier. The principle is friction, because on the laying surface, the component perpendicular to the foundation due to the loads, as well as the friction coefficient given by the soil-plate interaction, produce a resisting action that opposes the pull-out of the foundation from the ground. Knowing the geometry of the problem, the size of the plate will be fixed so as to ensure a minimum pull-out safety coefficient of 1.5.
STABILIZATION OF LANDSLIDED SLOPES Erdox Terra (dim. H310x360 cm approx. or H360x310 cm approx.) represents the quickest and safest solution for stabilization of landslide slopes.

ErdoX Terra is normally used to reprofile slopes subject to local instability and is effective and cost competitive in the case of soil slip surfaces that are not excessively deep. With numerous applications in very different conditions, Erdox has so far demonstrated particular efficiency and versatility, enabling intervention even in extreme conditions with low expense and remarkable structural and mechanical efficiency. By design and construction, ErdoX barriers allow the construction of elastic retaining structures capable of adapting to differential failures of the laying surface. Its conformation allows the barrier to be considered perfectly draining. Therefore, being unaffected by hydrostatic pressure, the structure shows high application capabilities even above surfaces with limited permeability.

ROAD CONSOLIDATION Erdox Terra (dim. H310x360 cm approx. or H360x310 cm approx.) represents the quickest and safest solution for emergency consolidation of roads with surface landslides that affect the traffic.
By design and construction, ErdoX barriers allow the construction of elastic retaining structures capable of adapting to differential failures of the laying surface. The advantages of the system in this type of application become particularly valuable as the time factor becomes critical. Our engineering department is available to offer support in assessing the application of the system to your specific design needs.
DEBRIS FLOW__Erdox Terra (dim. H310x360 cm approx. or H360x310 cm approx.) represents the quickest and safest solution for the active consolidation of slopes with debris flow issues.

This type of application is realized by reprofiling the slope aimed at reducing the velocities and, consequently, the velocities of the potential flow events. By design and construction, ErdoX barriers allow the construction of elastic retaining structures capable of adapting to differential failures of the laying surface. Its conformation allows the barrier to be considered perfectly draining.

HYDRAULIC WORKS_ErdoX Terra(dim. H310x360 cm approx. or H360x310 cm approx.) is particularly suitable for hydraulic works , both for the consolidation of banks and canals and for the realization of filtering weirs.

In this type of application, the elasticity of the system, which allows high adaptability to possible differential failures of the laying surface, amplify the advantages of the solution. The application of a DT net that turns up at the foot, upstream, for about 150 cm is essential in this type of work. This precaution, in addition to increasing the friction, has the function of guaranteeing the barriers from possible emptying of the backfilling soil, resulting from the occurrence of regurgitation phenomena at the foot. Hydraulic applications require careful analysis and design directed to contain the flow of water and debris considering the maximum runoff rates and hydraulic cross sections of the site, to define the best design solution. Our engineering department is available to offer support in assessing the application of the system to your specific design needs.
BANK CONSOLIDATION _They fall into the category of flexible works. In order to ensure optimal performance of these types of works, it is advisable to combine them with berms at the base to preserve the work from any regurgitation.

Also important is the material used for the backfilling, which must be of a suitable size so that it does not spill out of the structures. For these reasons, hydraulic applications require careful analysis and design with the aim of containing the flow of water and debris considering maximum runoff rates and hydraulic cross sections conceived to define the best design solution. Our engineering department is available to offer support in assessing the application of the system to your specific design needs.
FILTERING WEIRS_Hydraulic protections works are aimed at the arrangement of the river basin and have the purpose of determining a balance between the water excavation and transportation phenomena exercised in the watercourses and in the riverbeds, in order to prevent excesses of either activity from causing erosion or flooding.

It is crucial to proper insert the weir in the banks of the watercourse and the creation of an appropriate base useful to preserve the system from possible regurgitation at the basis given by the hydraulic jump generated by the construction of the cross work. Hydraulic applications require careful analysis and design directed toward containing the water flow and debris considering maximum runoff rates and hydraulic cross sections of the site made to define the best design solution.
