Rockfall protection network
Rockfall protection net woven twisted hexagonal metal mesh, into a package, each long curly 25m-50m. Protective net peace rockfall roll diameter under the wire diameter, coil length and PVC coating and, in order to facilitate loading and shipping transportation, each volume separately bound. The rockfall protection on the slope surface net or vertical hanging on the hillside, consider the slope height and steepness
When installing the first network on rockfall protection slope surface or vertical hanging on the hillside, consider the slope height and steepness. Rockfall protection net placement should be determined according to the different location, installation of rockfall protection network according to the actual situation, the slope surface treatment (removal of loose gravel particles, weeds and other debris).
Then the whole roll of rockfall protection network launched from the top down; this step is the most difficult operation. There are two kinds of specific methods of operation, a method will roll into the net to the top of the slope, the correction after the alignment, the network expansion is fixed on the uphill edge, is the net free fall out. This approach is applicable to the road leading to the top of the mountain, the mountain at the end of a telephone line, wire rods, railways and other public facilities. The other is the net start at the bottom of the slope, the hook will lift into the specified local fixed net. This need to hoist or crane. Use a hoist or crane operating restrictions, such as traffic congestion, when the highway construction space limit stenosis. In order to overcome the above limitations, the helicopter can also be used to install protective nets in rockfall, accelerate the speed of operation. When the hillside is higher than 25m, the helicopter is the best tool for the election.
Secondly, rockfall protection net and wall or slope fixed, the top of the slope surface and bottom fixed network.
Rockfall protection net is widely used in railway, highway, mining, hydropower engineering slope protection and large site boundary fence, rockfall, debris flow, protection of rockfall avalanches and even shallow slope disasters good governance effect.
