The outstanding performance of Chain Link Fence in various fields

Application of Chain Link Fence in Coal Mine Roadway Support Project:

1, Chain Link Fence is also called anchor net in coal mine application. When anchor net is installed, anchor bolt should be installed first. Live rock, dangerous rock, confirm the safety by the inside out, the first two sides after the middle of the order to remove the front beam on the backplane, remove the rock, rock, placed in the former beam to find a hook flower network , Then remove the top of the cap close to the head of the second bolt, press both sides of the uniform length and lap length of 100mm adjust and hang the hook flower net, and tighten the cap. And then linked to both sides of the chain-link fence and tight disk cap.

2, After the first row of bolting support is installed, go forward according to the order above, until a row of anchors close to the head does not exceed the distance between two anchors.

 

Precautions:

1, the installation of chain link fence and coal wall in close contact;
2, the use of chain link fence specifications for the length of 3 meters, 1 meter wide, mesh 5 * 5cm.
Application of Chain Link Fence in Shotcrete Slope Protection Technology:
First, the applicable conditions: Suitable for shotcrete or shotcrete protection of rock slope, when the rock cutting more fragmented, in order to further strengthen its protective effect, the use of anchor hook flower fence sprayed or sprayed concrete, so that a certain slope The depth of the rock to be reinforced.

 Two anchor chain link fence sprayed shotcrete and shotcrete protection requirements embedded in a stable rock in order to prevent the anchor slipped out of the slurry shelling caused maintenance difficulties, so be cautious when used. Second, the material requirements A pair of cement mortar and concrete material requirements and mix with the same spray and shotcrete slope protection The second anchor using φ16φ20 steel. Box with φ6 steel bar. Chain link fence with φ2 mm ordinary galvanized wire. Lashing wire using φ0.5φ1.0 ordinary wire.
Third, the construction method A clear brush slope surface loosening of rock and weathered rock and the slope is generally smooth pit embedding. Two air gun bolt hole depth than the bolt hole depth 20cm. Three high-pressure water gun holes flushing rock powder into the bolt perfusion 1: 3 cement mortar anchor and tamping dense.
Fourth, sweeping slope surface soil and rubble and further rinse with high-pressure water.

 Five, when the fixed bolt mortar strength of 70 will be prefabricated hook frame hooks installed on the bolt after the lashing welding that is bound to bind the chain link fence, chain link fence should be 1 cm away from the slope.
Sixth, spraying mortar or shotcrete spraying operations immediately after the completion of coverage with grass bag when the slurry to reach the initial setting after the start of sprinkler health so that the surface of the body often maintain wet health generally 710 days.
Construction Notes:
First, the protection of the surrounding and unprotected slope convergence of its treatment and shotcrete and spray the same slope protection.
Second, the anchor bolt anchorage depth and chain link fence mesh density depending on the nature of rock and weathering the general anchoring depth 0.51.0m screen spacing 2025cm.
Third, shotcrete thickness of not less than 3cm Sprayed concrete thickness of not less than 5cm Spray thickness should be uniform Do not make the chain link fence and head exposed.

 Performance of Chain link fence in the flood season:
Flood season prevention, Chain Link network played an important role? The two pre-bent wavy metal wires are weaved in a plain weave pattern. Since the metal wires are preformed by bending the metal molds, the metal wires in two directions can be arranged in relatively correct positions so as to ensure that the meshes The absolute size of the straight. Wrap stainless steel ginning network convenient and easy to use, use a long time, not easy to handle, weft back and forth wrapped around, not easy to fall, solid structure.
