As a special type of anchor cable, the cage cable has its unique advantages and disadvantages. The following is a detailed analysis of the advantages and disadvantages of the cage cable:
Advantages:
1. Tight and stable structure: cage cable is composed of cage, bolt, anchor and other parts. The cage is generally made of metal tube, which makes it have stronger anti-deformation and anti-torsion ability.
2. Strong resistance in multiple directions: the cage anchor cable can not only strengthen the overall strength of the support body, but also withstand the force in multiple directions, which is conducive to the uniform distribution of internal stress in the support body.
3. Adapt to harsh environment: Mine cage anchor cable is especially suitable for support and reinforcement under complex geological conditions, such as weak, top film, moisture and other conditions are harsh geological environment.
4. Improve mining efficiency: It has significant advantages in the treatment of coal seam roof and the support of the "three soft" section, which can greatly improve the mining efficiency of the working face.
Cons:
- The construction is difficult: the construction of the cage cable needs to be fixed after the steel wire is twisted in the cage core and made strong, which requires professional operation technology and a long construction period.
- Rust prevention is difficult: Because the internal steel wire of the cage cable is twisted together, it is difficult to carry out rust prevention treatment when laying, and corrosion is easy to occur in the long-term use process, affecting the service life.
- Debris easy to get stuck: The structural characteristics of the cage cable make some debris easy to get stuck, which affects the fixing effect of the anchor rod, and even leads to the destruction of the anchor rod.
In summary, the cage cable has significant advantages in structure, stability and environmental adaptability, but there are also some challenges in construction, rust prevention and debris prevention. In practical applications, it is necessary to select and adjust according to the specific environment and requirements.
