It is important to have such a suspension cable in the bridge, as almost all of them will suffer varying degrees of damage over time. This is mostly due to poor management and potential hazards. If problems occur in a short period of time, maintenance may still be possible, but serious problems require major repairs or even early replacement to avoid waste. So we can take a look. It is not uncommon for structural hazards like this to collapse, and in severe cases, they may even threaten people's lives.
What are the hidden dangers of suspender cables like this? Let's take a look. The first one is the pipes embedded in the college, which may pose hidden dangers. The pipes buried below refer to the cable body of the cable car and the corroded anchor head. Improper treatment may lead to corrosion, and water or rainwater may directly enter the embedded pipes, causing water ingress problems. Moreover, this situation occurs due to insufficient sealing, so condensation and water accumulation will occur after the humidity temperature decreases.
This is a common occurrence in suspension cables and poses a threat to their lifespan and stability. So let's take a look at the aging or cracking of this material. Currently, the sheaths we use are all protective.. Since its use in the 1980s, it has been consistently used, but in recent years, various aging and cracking changes have occurred, leading to the problem of rust on the wires inside.
In addition to material processing technology and other aspects, it is because of the structural characteristics of this suspension rod and cable. So let's take a look at the third one, because both the bridge deck and the load are borne by this suspension cable. When the temperature changes, it will swing accordingly. Although this one is fixed, if it keeps swinging, the wear time will be longer. Also, due to the relatively small mass and damping of the steel group, vibration is prone to occur.
Under the combined action of wind and rain, it has been found that the phenomenon of significant pulling is relatively large. Due to the large vibration of the suspension rods and cables, the destructive force can also threaten the entire bridge, which has become a concern in the design process. Tianjin Chenqing Metal Products Co., Ltd. is a process manufacturer that independently develops and produces equipment in China. It has rich experience and is also a growth enterprise. The company is in line with national standards and industry regulations.
Our team is composed of experienced technical personnel and practical technical personnel. If you have any needs in this area, you can contact us anytime and anywhere. We have a wealth of experience and technical connections, and we can help you develop better works.

Precautions for cable force detection of bridge suspension rods
Bridges are an important component of the entire road transportation network. In recent years, with the rapid development of China's traffic network and the continuous innovation of bridge construction methods, long-span cable-stayed bridges, suspension bridge and other cable structure bridges are playing an increasingly important role in traffic. As the lifeline of the cable structure bridge, the suspension rod cable is an important stress component that cannot be ignored.Due to the important position of suspension rod and cable force in the entire bearing system of cable structure bridges, cable force directly reflects the internal force state of cable structure bridges in a continuous state and is an important indicator for evaluating the bearing capacity of bridges. Whether the cable force is within a reasonable range will directly affect the overall stress state of the structure and the smoothness of the line. Therefore, detecting the cable force of bridge suspenders is an imp...
Non-destructive testing technology for internal corrosion and broken wires of bridge suspension rods and cables
The main reasons for the damage of bridge suspension rod and cable system include natural disaster damage and long-term cumulative damage of cables. Natural disaster damage mainly refers to the damage caused by strong winds, floods, earthquakes, and floating object impacts, which are mainly prevented through necessary protective measures; Long term cumulative damage refers to the long-term unstable load of bridge suspension rods and cables caused by factors such as fatigue and corrosion, which are hidden dangers such as pitting corrosion, reduced effective cross-sectional area, and wire breakage caused by fatigue and corrosion.Due to the harsh working environment, the current protective measures that can be taken cannot avoid corrosion and fracture of bridge cables and members, and the bridge suspension rod cables and suspension rod cables will inevitably rust. However, due to the shielding effect of the sheath of the suspension rod cables, it is not possible to directly analyze the co...
What are the functions and prospects of epoxy coated steel strands?
1、 At present, epoxy steel strand is mainly used for cable-stayed bridges and anchor ingots with high anti-corrosion performance requirements. Excellent anti slip and wear resistance, short curing time, fast opening to traffic, and high cost-effectiveness. Epoxy resin coated steel bars are a type of coated steel bars produced under factory production conditions, using electrostatic spraying method to spray epoxy resin powder on the surface of ordinary ribbed steel bars and ordinary plain round steel bars. Epoxy resin coated steel bars have excellent corrosion resistance and significantly lower bonding strength with concrete. They are suitable for reinforced concrete structures in industrial and civil buildings, general structures, roads, bridges, ports, docks, etc. in humid environments or corrosive media (when used in industrial building anti-corrosion engineering, it should also be checked with relevant standards). The template engineering and steel reinforcement damage at the cons...
