The cantilever form traveler technology is widely used in bridge construction. Due to its characteristics of simple structure, convenient production, and economic affordability, it has received more and more attention and emphasis. However, currently, there are still many deficiencies in the construction technology and methods of the cantilever form traveler. Let's take a look at this in this article.

1. Uneven concrete quality

Uneven concrete quality is a common problem in the application of cantilever form traveler technology in bridge construction. This problem is usually caused by improper concrete mixing, uneven stirring, or improper pouring methods. Once there is uneven concrete quality, cracks will appear in bridge components. In cantilever form traveler technology, uneven concrete quality will bring great risks to construction. Because concrete is the main material supporting the bridge, if the concrete quality is uneven, the stability of the bridge will be affected, which may lead to serious safety accidents. To avoid the impact of uneven concrete quality on cantilever form traveler technology construction, we need to take a series of measures. First, operate strictly in accordance with the concrete mixing standards to ensure that parameters such as the concrete mixing ratio and stirring time meet the requirements. Secondly, when pouring concrete, adopt an appropriate pouring method to ensure that the concrete is evenly distributed throughout the pouring process and avoid local uneven quality. Finally, after the concrete pouring is completed, carry out sufficient curing to ensure that the strength and stability of the concrete are guaranteed.

2. Greatly affected by wind and vibration during hoisting

In bridge construction, cantilever form traveler technology is widely used. However, during the hoisting process, it is often affected by wind and vibration, which is also a major problem currently. First, the wind will have a great impact on the suspended form traveler. Due to the large area of the suspended form traveler, once the wind force increases, it will have a greater impact on it. This will not only affect the construction but also endanger the safety of workers. Therefore, during the construction process, special attention needs to be paid to changes in wind force and corresponding measures should be taken in time. Secondly, vibration is also a major problem in the construction process of suspended form travelers. Vibration will cause the suspended form traveler to shake violently, increasing the difficulty of construction and even causing physical discomfort to workers. Therefore, in the design and suspension process of the form traveler, vibration factors need to be fully considered and corresponding measures such as increasing support points should be taken. Finally, in order to avoid being affected by wind and vibration, it is necessary to fully evaluate and calculate the position and height of the suspended form traveler before construction. Only after sufficient evaluation and calculation can the safety of the suspended form traveler and the smooth progress of construction be guaranteed.

3. Insufficient structural stiffness and prone to inclination

Problems in the application of cantilever form traveler technology in bridge construction: Insufficient structural stiffness and prone to inclination. Cantilever form traveler technology is a common bridge construction method, but there is a problem of insufficient structural stiffness in its application, which is easy to lead to inclination. This problem is mainly due to the unreasonable structural design of the cantilever form traveler, not considering the actual situation of the construction site, resulting in instability during the construction process. In actual construction, if the structural stiffness of the cantilever form traveler is insufficient, it is very easy to tilt, which will affect construction efficiency and safety. Once there is inclination, it will not only affect the progress of bridge construction but also bring serious safety hazards to the construction site, possibly leading to casualties and equipment damage. Therefore, to solve the problems of insufficient structural stiffness and prone to inclination of cantilever form traveler technology in bridge construction, it is necessary to strengthen structural design and construction management. When designing the cantilever form traveler, the actual situation of the construction site should be considered, and the structural parameters should be reasonably determined to ensure structural stability. At the same time, during the construction process, monitoring and management should be strengthened, and problems should be dealt with in time to ensure construction safety and quality.

This article mainly introduces the problems existing in the application of cantilever form traveler technology in bridge construction, including cracks in components caused by uneven concrete quality, being greatly affected by wind and vibration during hoisting, and being prone to inclination due to insufficient structural stiffness. These problems will affect construction efficiency and safety and may even lead to casualties and equipment damage. What are the ways for us to solve these problems?
