Prestressed Steel Wire

Product Details：

Mining anchor ropes are widely used in coal mines and other mining projects to reinforce shafts and surrounding rocks. Conventional anchor support often fails to provide effective support when faced with complex conditions, resulting in total collapse. Mining Anchor Cables are uniquely designed to provide strong pre-stress support by securing the anchor loop to the hard top plate without length limitations. The high-strength steel cables can tightly integrate the underlying strata with the composite roof plate to form a solid one-piece rigid roof plate, effectively providing excellent support and ensuring the safe and smooth progress of the project.

Prestressed Steel Wire

Structural Characteristics.

Anchor structures are characterized as being used to stabilize unstable rock by anchoring one end in hard rock formations in boreholes through weak rock formations or sliding surfaces, and then applying tension through the other free end to apply pressure to hold the rock in place.

Prestressed Steel Wire

Areas of application include:

Used to reinforce prestressed concrete structures such as railroad and highway long-span bridges, bridge crane girders, geotechnical anchoring works, multi-story industrial buildings, stadiums, coal mines, etc.

PC wires for bridge suspension and stay cables in accordance with ASTM A416-10, 270k strength with low relaxation properties.

PE coated/clad strand for extra protection and durability in large span concrete floor slabs, high load precast beams and other specialty structures.

Prestressed Steel Wire

Usage.

First drill the hole according to the diameter and length of the anchor cable and clean the debris in the hole. Subsequently, inject appropriate amount of resin anchoring agent and push it to the bottom of the hole with the anchor cable, then connect the end of the anchor cable to the anchoring machine and start the agitator to mix as required. After the resin is cured, install the pallets and anchors, and use the tensioner to apply preload to the specified value to complete the operation.
