A Community investment of more than 1.2 million euros will strengthen hillsides in three municipalities of the Ricote Valley and thus avoid possible landslides.
This hillside consolidation project, in particular, will be developed throughout this year and early 2020 in different areas of Blanca, Ulea and Ojós, municipalities that share similar geological features prone to falling and falling rocks.
The stabilization and defense works, which are already being carried out in Blanca and Ulea and will begin at the beginning of 2020 in Ojós, will consist of the installation of two main types of containment elements, such as dynamic barriers and meshes.
In the first case, it is the placement of high-strength fences capable of stopping an impact equivalent to that produced by a 20-ton rock at a speed of 100 kilometers per hour.
The other technique used is the bagging, that is, the installation of high-strength meshes that surround the rocks and that are fixed to the ground by high resistance cables and piles driven into the rock itself.
The General Director of Medio Medio, Consuelo Rosauro, said that these are preventive actions with which it is intended to protect the urban area of â€‹â€‹these municipalities "in the face of possible landslides or rock falls, a recurrent problem in this area and that may be aggravated with episodes of rain and that is related to the geological composition of these mountains ".
Specifically, the mountains located in the Ricote Valley are characterized by the contrast between soft geological materials in the low areas (marls and clays) and hard at the top (conglomerates and calcarenites of the Miocene.) This makes the erosion of soft materials leave the hard materials cantilevered or with unequal supports, which can generate its fracture and the slope detachment under the detached blocks.
Specifically, in Blanca will be bagged nine large blocks, work in which 795,437 euros will be invested.
In Ulea, meanwhile, the preexisting work will be completed with the installation of 50 meters of dynamic barrier and the bagging of a large block of rock, actions that have a bidding budget of 70,575 euros and 194,404 euros respectively.
These works will be developed on the hillsides adjoining both municipalities of the public utility mountains La Navela, El Solán, La Muela and Montoro and La Solana, Las Lomas, La Navela and La Serrata.
Finally, in Ojós the Ramón y Cajal street defense work will be executed through the placement of 190 meters of dynamic barriers, budgeted in this case at 233,153 euros.
All these actions are co-financed by the Autonomous Community of the Region of Murcia together with the European Agricultural Fund for Common Development (Feader).
