Ordinary anchor cables refer to anchor rods made of steel strands, steel plates, or prestressed steel bundles, which are fixed in engineering structures to withstand forces such as earthquakes, wind loads, hydraulic impacts, and structural deformations. The following is a detailed introduction to ordinary anchor cables:
Construction and installation
The construction method of ordinary anchor cables mainly includes the following steps:
1. Reserved holes or spaces: Reserve certain holes or spaces in the engineering structure to facilitate the fixation and use of anchor cables.
2. Insertion and fixation: Insert the anchor rod into the hole or space, fix it in the structure with anchors, pads, etc., and create a certain tension.
3. Adjustment and reinforcement: Adjust the tension of the anchor cable according to actual needs, and further reinforce and repair the anchor.
During the installation process, it is also necessary to pay attention to checking the consistency between the anchor cable number and the hole number, as well as performing steps such as hole cleaning and calibration of tensioning equipment to ensure the correct installation and effective operation of the anchor cable.
Function
Ordinary anchor cables mainly serve the following functions:
1. Support function: By supporting the structure, it can resist external forces such as groundwater pressure, seismic force, and wind force.
2. Strengthening effect: increase the stability and load-bearing capacity of the structure.
3. Protective function: prevent minor underground landslides, loosening, and other phenomena, and improve the safety of the structure.
Application Fields
Ordinary anchor cables have a wide range of applications in construction engineering, bridge and tunnel engineering, and their application scenarios mainly include the following aspects:
1. Reinforcement anchoring: In concrete structures such as beams, columns, walls, etc., ordinary anchor cables are used to firmly fix the reinforcement, achieving the purpose of strengthening and stabilizing the structure.
2. Bridge construction: commonly used suspension cables, suspension rods, diagonal braces, etc. for large bridges to stabilize the bridge and bear a portion of the load.
3. Tunnel engineering: In underground engineering (such as tunnel lining, grouting, bottom plate, arch shell, etc.), ordinary anchor cables are used to increase the strength and stability of the tunnel structure.
Material and Characteristics
The materials of ordinary anchor cables are diverse, mainly including steel strands, steel plates, and prestressed steel strands. These materials have different characteristics and applicable ranges, such as wear-resistant, corrosion-resistant, and high-temperature resistant steel strand anchor cables, suitable for multiple fields such as offshore, mining, and construction; Synthetic anchor cables (such as polyester, polyimide, aramid, carbon fiber, etc.) have the characteristics of high strength, light weight, and good durability, but their service life is relatively short and they are easily affected by ultraviolet radiation and chemical corrosion.
