In the areas of lands consolidation and reclamation, protection of excavation walls and in the resolution of problems related to phenomena of instability, Geovertical intervenes with special equipment and highly skilled technicians caring not only for the execution of the works but also of all the steps necessary to the success and quality of the final result.
Before carrying out any work, an enterprise makes soil studies to identify the characteristics and especially the weaknesses and subsequently determines the most appropriate type of intervention. A very common practice in the maintenance of the territory, in order to achieve the consolidation of unstable soils and rock surfaces, is the consolidation through pilings.
The execution of micropiles can satisfy various problems that arise in the construction field. In areas where the use of direct foundations it is not possible, it is difficult or uneconomical - ground is poor lift, or particular logistical conditions or requirements of the project - micropiles allow to transfer the superstructure loads deep into the suitable geotechnical conditions.
Micropiles are also an effective redevelopment of existing foundations as they respond to the needs of the project involving the load increases on existing foundations in the event of restructuring and are an excellent solution for the safety of damaged buildings.
The static function of bored piles cast in situ is comparable to real columns with the base resting on soil layers with better geo-mechanical characteristics than those one overlaying. The spread of big construction with floor distribution of heavy loads has increased the interest in large-diameter bored piles.
Steel tie rods are one of the oldest and most effective techniques of consolidation to strengthen structural elements. The applications of tie rods are multiple: to increase the resistance of a wall in its own plane, to reduce the possibility of tipping out of the plane, to reduce the static thrust of thrusting structures. Tie rods are resistant metallic elements consisting of a cable or a rod or a strand and of a key or anchor plate.
Tie rod starts working when under tensile stress (it may occur for example when a wall tends to overturn or fall apart). For the system to be in equilibrium, the cable or rod must be able to withstand the tensile force to which it is subjected. This force is transmitted to the key or plate, which is in contact with the structure must be able to withstand the contact voltage between them.
In a consolidation project, the goal is to increase the risk indicators of a construction. In other words, buildings or rocky slopes lacking from the point of view of the resistance against external actions need to be consolidated to increase resistance. Unlike other consolidation techniques (some are suitable to increase the resistance from global analysis point of view, others are suitable to increase the local analysis), tie rods can be used to increase both the strength analysis of global and local type.
The realization techniques such as drilling and the anchorage method, are defined in relation to the nature of the materials to pass through, while the equipment to be used is extremely specialized, and it can often be disassembled to be heli-transportable, and in any case strong, and, at the same time, light enough, so that it can be used in the wall.
