Concrete launched with welded mesh reinforcement

The concrete launched helps to cover the slope in certain sub-sections, has a thickness of the order of 6 to 10 centimeters, its use requires a previous placement of welded mesh with wires of 3.43 millimeters in diameter and with an opening of 10 x 10 centimeters ; The mesh must be placed from top to bottom as the cutting progresses.

The mesh is fixed to the slope by short anchors of 50 centimeters in length and with a diameter of 13 millimeters, forming a grid with separation of 2 meters. For irregular surfaces, the grid can be closed to ensure that the mesh is glued to the surface of the slope, the mesh must cover an area of ​​about 2 meters inwards, from the line of cut zeros. To avoid infiltration and volumetric changes in the interior of the cut, it must be covered by means of flapping (previous placement of the metallic mesh).

This work can take advantage of the advance in the casting of the cut, starting with the afine and softening of the slope, which allows the placement of the electrowelded type mesh of 3.43 millimeters in diameter and with an opening of 100 x 100 millimeters, which is anchored To the wall of the cut from the zeros, following the contour of the ridge and tending it later on the slope of downstream.
The mesh must be attached to the wall of the cut, its completion is carried out up to the upper level of the gutter, which ensures that it is fastened enough to be anchored at the bottom. The overlaps of the mesh are 30 centimeters, these must be lashed with annealed wire and anchored properly to be able to apply the launched concrete to them.
 
Placement of cast concrete
The surface where the concrete will be thrown must be properly tuned, profiled and the mesh softened perfectly on its entire surface. Once the mesh has been made and the mesh is properly secured to the slope, the concrete is released, maintaining a distance between the nozzle and the surface of approximately 1 meter; The throw must be made by moving the nozzle in a continuous series of circular or elliptical overlapping arcs. Care should be taken not to leave holes behind the mesh wires, to achieve this, the nozzle angle can be varied, but in general, it should remain perpendicular to the surface of the slope. The resistance of the concrete, at 28 days, should be f'c = 200 kg / cm2.
 

Cyclone anti-glare mesh for central motorway barrier
Cyclone anti-glare mesh is an alternative to anti-glare mesh for urban, suburban, or high-pitched skirmish. Due to its physical characteristics, it functions as a screen or visual barrier to intercept the light of the lanterns of the vehicles that circulate in contradiction, with which the risk of dazzling of the drivers that circulate by the motorway is reduced.

Technical specifications
The anti-glare type cyclone mesh has an opening of 17 x 17 mm, with steel core of galvanized wire inside (caliber 12.5), lined with PVC (polyvinyl chloride), black on the outside with a final gauge of 10.5 And with node termination on both sides.
