The Town Planning Council of Lorca, José Joaquín Peñarrubia, reported this morning that the city council has begun work aimed at stabilizing an existing rock mass Murviedo street, particularly in the area of ​​San Lazaro Ramblilla.

The report on the emergence of these works, with regard to the north of that solid, points out that there has been a "massive destabilization of existing rockfall has caused" so "should proceed to Manually sanitizing unstable parts of the slope, to the placement of a containment mesh anchored to the ground with self-tapping steel bars, which provides support to 5'0 Knewton unit (unit of measurement of force) / m for a Safety Factor = 1 ' 67, and the installation of a mesh of an anti-erosion, high density polyethylene for the treatment of three-dimensional slope. "

To the east is set to be proceed to manual sanitizing unstable slope areas, the placement of a mesh containment, reinforced steel cables anchored to the ground with self-tapping steel bars, which provides support to unit 60 kN / m² for a FS = 1'67 and installing a simple torsion mesh attached and anchored to the ground with bolts 1 meter in length. "It's a performance similar to the one developed in the slope of the castle , which has offered such good results, demonstrating its strength in episodes such as the earthquakes in 2011 and flooding last September.

This paper describes a "highly fractured rock mass has generated a rock weighing more than two hundred tons and threatens discard; This rock has a very unstable equilibrium because, in addition to the action of earthquakes that are happening in your top drive has a crack of more than 25 inches thick, is separated at the sides and is supported on a sand layer which rapidly deteriorates due to the action of rainfall, all this involves a high risk of causing a detachment of the rock and a significant danger to the houses in the street and neighbors Murviedo passing through this street.
