Surface active protection system of wire rope net on all kinds of needed for flexible network mask wrapped in protective slopes or rock, rock slope with constraints and rock weathering loss of or damage to the soil to collapse (reinforcement), or to manipulate rock fall within a certain planning movement (containment action).
Below is the surface active protection system installation method:
1, take the initiative to slope fence installation process according to the planning and combining with field practice topography measurement location of steel column and anchor foundation.The pay-off length should be length add about 3-8% than the planning system, the terrain is bigger.System when settle difficult settled along the same contour line take maximum 8%.In relatively flat terrain rules, the system can settle basically in the same contour along a straight line when settled down 3%.On this basis, the column spacing can be adjusted for planning interval 20% shortened or widening planning.
2, excavation (not the mask layer thickness, when the excavation depth to bedrock and had not reached the planning.In the inside of the foundation anchor hole drilling anchor hole azimuth, to anchor into upper bedrock and perfusion after grouting foundation concrete).
3 and embedded bolt and grouting foundation concrete (on rock foundation, process should be drill bolt holes and bolt installation.For concrete foundation, also after perfusion foundation concrete drilling anchor installation).
4, base installation: the base set into the anchor bolt and nut and tighten.
5 pull up anchor rope, steel column, and the installation.
The installation: 6, lateral tensile anchor rope to pull up the anchor rope.Only after pulling anchor rope is installed on.
7, the support line installation.
8, under the support line installation.
9, the installation of steel rope net.
10, wire mesh grille installation.
