Cast-in-place box girder construction technology occupies an important position in the highway bridge industry. The effective use of construction technology is one of the important conditions to ensure the quality of precast box girders. This article will delve into the structural characteristics and benefits of cast-in-place box girder construction in detail.

1. Structural Characteristics of Cast-in-place Box Girder Construction

In the construction of highway bridges, the overall development trend has achieved an unprecedented improvement, immediately promotes the widespread application of the cast-in-place box girder structure. Considering the lightness of the prestressed reinforced cast-in-place box girder structure, to maintain the overall relative height and span, it is necessary to fully utilize the advantages of the concrete of the precast box girder structure to provide more efficient ideas for the highway bridge route design. Furthermore, it can not only achieve better span and planar curve radius, but also eliminate the influence of the terrain or obstacles to achieve stronger internal conditions. Judging from the current situation with cast-in-place box girders, one-time overall casting can achieve better stress-bearing effects and ensure that the overall physical properties and stiffness meet current traffic requirements. In addition, during the cast-in-place box girder construction process, it does not need to occupy a large construction site and does not need to squat on the main girder for support. Through direct and simple operations, the stability and lightness of the upper and lower structures are ensured, and the stability and reliability of the external structure are further improved.

2. Advantages of Cast-in-place Box Girder

2.1 Reliable Performance

According to the efficient setting of the cast-in-place box girder structure, it has a promoting effect on the bridge. Judging from the structural form, the box girder has a large range and a small cross-sectional height, which is suitable for large span bridge projects and can maintain the stability of the bridge structure, which plays a crucial role in the safe operation of the whole bridge.

2.2 Economy

Cast-in-place box girder construction technology is the sum of the products of the era of the development of scientific and technological level. Compared with traditional construction technologies, this new technology is more economical. Although there are many processes in cast-in-place box girder construction, some processes can be simplified. In addition, cast-in-place box girder construction mainly uses some materials that are easy to purchase and have low prices, which can not only ensure the construction quality of the bridge, but also further reduce the construction cost of the bridge construction project.

2.3 Aesthetics

Cast-in-place box girder construction is flexible and can be adjusted appropriately according to the project requirements and specific circumstances. And the box girder structure form itself has the characteristics of diversity, which can be directly set on the pier body without the need for the support pier machine cover beam structure. At this time, the formed bridge shows good aesthetics, which is conducive to improving the appearance of the bridge.

Conclusion

Cast-in-place box girder construction has the advantages of light structure, strong adaptability, reliable performance, economy and aesthetics. Its widespread application in highway bridge construction can not only improve the stability and safety of the bridge, but also provide more flexibility for the route design. With the continuous development of construction technology, cast-in-place box girders will play a more important role in the field of transportation infrastructure construction.
