Anchor Lock
Mining cable anchors refer to anchors that are installed at the exposed end of the anchor cable (steel strand) in coal mine tunnels and can be tensioned.
Mining cable anchors refer to anchors that are installed at the exposed end of the anchor cable (steel strand) in coal mine tunnels and can be tensioned. After tensioning and pre-tensioning, the tensile force of the anchor cable can be transferred to the supporting surface. , plays the role of maintaining the tunnel passage. It plays a great role in prestressed tension construction projects such as mines, tunnels, and bridges. Common system classifications of anchors:
(1) Circular anchor. This type of anchor has good self-anchoring properties. Tensioning generally uses through-core jacks.
(2) Flat anchor. Flat anchors are mainly used for transverse prestressing of bridge decks, hollow slabs, and low-height box girders to make the stress distribution more uniform and reasonable and further reduce the thickness of the structure.

Composition
Anchor cables are generally composed of wire ropes, anchors, prestressed elements, etc.
1. Wire rope
The steel wire rope is one of the most important components of the anchor rope. It is composed of multiple strands of metal wire ropes. Its main function is to withstand the tension of the anchor cable, and at the same time it must have a certain degree of elasticity to cope with changes in the external environment.
2. Anchors
The anchor is another important component of the anchor cable. It is mainly used to fix the wire rope in the soil or rocks to prevent it from being pulled out or sliding. The material selection and design of anchors must consider various factors such as geological conditions, anchor cable tension and external forces.
3. Prestressed
Prestressing is a way to gain additional strength in a structural system in the form of anchor cable tension. Prestressed anchor cables are usually used in large bridges, foundation treatment, deep foundation pits, tunnel excavation and earthquake projects. It increases the load-bearing capacity of the structural system by converting the compressive stress on the steel wire rope into the prestress of the concrete or rock mass.
4. Other auxiliary materials
In addition to wire ropes, anchors and prestressing forces, anchor cables also require some auxiliary materials, such as anchor cable protection tubes, guide wheels, tension instruments, etc., to ensure good performance and safety of the anchor cables.
Installation
1. Preparatory work
1.1: Determine the engineering location and length of the anchor cable.
1.2 : Arrange the specifications and tensioning method of the steel strand.
1.3: Prepare the required tools and equipment, such as lifting machinery, etc.
1.4: Make sure the work site is safe.
2. Anchor installation
2.1: Determine the installation location of the anchorage, and conduct ground detection and marking.
2.2: Drill holes and clean the dust, soil and other impurities in the holes.
2.3: Install the anchor, insert the anchor into the hole and pour concrete for reinforcement to ensure the anchor is tight.
2.4: A load test should be performed after installing the anchor to ensure that the anchor can withstand the expected load.
3. Rope installation
3.1: Install accessories such as ties and pads on the anchor.
3.2: Insert the rope, insert the steel strand into the anchor in advance, maintain a certain tension, and maintain the verticality and flatness of the rope.
3.3: Use special tools to tighten the rope until the tension reaches the design requirements.
4. Tension
4.1: Install the tensioner and connect the ropes.
4.2: Tension according to the design requirements until the required preload force is reached.
4.3: During the tensioning process, each rope should be monitored to ensure that the tensioning strength meets the requirements.
4.4: Tension according to the specified tensioning level, and perform tensioning and locking when the requirements are met.
5. Acceptance
After the anchor cable is installed, acceptance should be carried out, including load testing, visual inspection, measurement and testing, etc. Make sure that the installation of the anchor cable complies with relevant standards and requirements, and it can be put into use only after passing the acceptance inspection.
