Bologna. The consolidation of the town of Gobbi, in the Piacenza area, begins. An innovative intervention worth 950 thousand euros to reduce hydrogeological instability.

The construction of a double screen of drainage wells and a bulkhead of poles is planned to protect the town and the municipal road. Work has also been planned to improve the efficiency of the minor network of the Trebbia basin.

Bologna. The consolidation of the town of Gobbi, in the Piacenza area, begins. An innovative intervention worth 950 thousand euros to reduce hydrogeological instability.

A double screen of 53 wells with drainage function, a bulkhead of containment poles along the municipal road and works to improve the efficiency of minor watercourses in the Trebbia basin.
These are the consolidation works started in Gobbi, a town in the Piacenza area located on a landslide slope that has been the subject of specialist studies and investigations for years.

Financed by the Pnrr with 950 thousand euros, the works will allow the implementation of an important structural intervention to mitigate the instability and increase the safety of citizens, production activities and public infrastructures, in an area characterized by a very high hydrogeological risk.

The project , particularly innovative, is managed by the Piacenza Territorial Office of the Regional Agency for Territorial Security and Civil Protection, which also manages the works.

The work plan

First of all, it is planned to be carried out the draining wells, which can be inspected and are up to 20 meters deep, connected by a pipeline for the discharge of underground water. They will be positioned upstream and downstream of the town of Gobbi, with the aim of draining the underground water and, above all, preventing pressure on the ground due to saturation, which causes landslides. A large part of the wells will then be buried so as not to be visible and therefore not affect the landscape.

Along the municipal road north of the town, an area subject to subsidence, a bulkhead of bored concrete piles will be built with a containment and consolidation function.

Lastly, to ensure correct water flow and good natural drainage of the slopes, action will be taken to improve the efficiency of the Rio degli Antarelli and the minor water network, the disposal route for the water collected from the wells.

All the soil obtained from drilling can be reused to fix slopes, thus improving surface runoff. Finally, at the end of the works, the surface vegetal soil removed during the excavation will be restored throughout the entire construction site area, to quickly recover the conditions prior to the intervention.

Bologna. Via al consolidamento dell'abitato di Gobbi, nel Piacentino. Intervento innovativo da 950mila euro per ridurre il dissesto idrogeologico.
