Description

Technical Field

[0001] This utility model relates to the field of box girder support technology, and in particular to a cast-in-place box girder support structure. Background Technology

[0002] In the construction of modern transportation networks, the scale and complexity of bridge projects are constantly increasing. The continuous growth of urban traffic flow makes the demand for large and stable bridges more and more urgent, and the importance of cast-in-place box girder support structures is becoming more and more prominent. Whether crossing rivers, lakes and seas or building a three-dimensional transportation system in cities, high-quality and reliable cast-in-place box girder support structures are the foundation for achieving safe and efficient bridge construction. Their performance and design rationality are directly related to the quality, progress and safety of the entire bridge project after completion.

[0003] In early bridge construction, cast-in-place box girder supports used simple wooden structures and basic steel pipe supports. However, these supports were limited in form, relied heavily on manpower for erection and dismantling, were inefficient, and had significant limitations in load-bearing capacity and stability, making them unsuitable for the construction of large-span, complex box girders. With the development of building materials and engineering technology, modern cast-in-place box girder support structures have become increasingly diversified. Among these existing support structures, full-span supports occupy a large area, are less flexible in areas with limited space, and have high requirements for the bearing capacity of the foundation. Steel pipe Bailey supports, on the other hand, have high requirements for site conditions and equipment during installation and dismantling, which to some extent limits their application.
