"

Councilman Lorca City Council Planning and acting mayor, Francisco García, announced this morning the start of construction of the first action on the side of the castle to the consolidation of the hill, avoid rock falls, that posed a potential danger to residents and visitors to Uptown, which began today.

"

Urban Councilman emphasized that "this government team is putting the solutions during the previous municipal governments did not, although three studies drafted."

"When the Popular Party to power these jobs were obsolete, so it was necessary to conduct a new study, which was entrusted to a specialized company, which had already drawn one of the previous studies," Garcia clarified.

"The priority in this initiative is to provide security to the most dangerous because of its proximity to housing, while protecting the road down the castle, which is disabled to avoid risks," stressed the council.

Garcia added that "once it resolves this issue more problematic, we will continue to make efforts to secure the necessary financial support to undertake the subsequent phases of consolidation in other sectors identified in the study, and require less urgent intervention ".

"This project is coordinated with the other aimed at strengthening the fortress wall, which runs Turespaña within the final construction work of the Parador," said the mayor.

The geological and geotechnical situation of the solid rock on which the castle of Lorca is very complicated, with a completely broken and unstable ground, a problem compounded by the severe weather and earthquakes, as Lorca is located in the active fault Alhama, Murcia.

Through extensive field testing and analysis, reports commissioned established four areas of action, depending on their urgency.

Zones 1 and 2 located from the water tank, between the road down and the walls are those that are in worse condition and require this emergency action.

Zone 3, in the vicinity of Parador, is more stable and would be following in the act.

And Zone 4, which is the side that faces the river Guadalentín, requires less urgency.

The project includes the installation of a flexible sheet consisting of a diamond mesh steel wire, high-capacity resilient.

Beneath this mesh is placed another smaller holes in direct contact with the rock, so that small stones can not fall.

The meshes provided in this work, funded by the State Fund for Employment and Local Sustainability, will be anchored by steel rods (from an average length of 9 meters) hosted punched the ground, in order to exert a uniform pressure on the sliding surface.

Other anchors provided are based on cables that tie the perimeter, while other cables are designed to link the networks, as well as the support and load transfer to join the network anchors.

These metallic elements to be glued to the ground, to prevent its destruction, be made of special anti-corrosive treatment.

In the area number 1, the total area on which to act is 498 square meters, while the number 2, that area reaches 1,985 meters square.

Another element to be placed to stop erosion are small loose stone walls surrounded by a galvanized wire mesh that hinder the passage of sand and fillings, called gabions, of which it is planned to place about 21 meters linear 30 centimeters thick.

However, the project may be modified in some respects, thanks to the improvements referred to in the award.
