BIM standardized modeling method for high-speed railway swivel bridge

Abstract

The invention provides a BIM standardized modeling method for a high-speed railway swivel bridge. The BIM standardized modeling method comprises the steps of data preparation, reasonable selection ofsoftware, creation of a bridge cast-in-place structural member, creation of a spherical hinge prefabricated member, creation of a site temporary facility, creation of a site layout model, fine correction, model space integration and the like. According to the method, BIM (Building Information Modeling) software is adopted, multi-source information of the swivel bridge component is integrated and recorded into a standardized component, so that various models on site are established, and the method is suitable for high-speed railway swivel bridges and other railway and highway swivel bridges andcan be used for visually guiding swivel bridge spherical hinge installation, bridge construction procedures and the like.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a BIM standardized modeling method for a high-speed railway swivel bridge. Background technique [0002] With the continuous improvement of infrastructure construction, the concept of opening roads in mountains and building bridges in water has become a consensus. More and more bridges need to cross complex terrains such as mountains, rivers, and canyons, and the difficulty of bridge span and construction technology is also increasing. Swivel bridges have obvious advantages in crossing obstacles, so they are increasingly used in unfavorable terrain. [0003] Whether it is a swivel bridge or an existing girder bridge, the traditional design disclosure generally uses AUTOCAD drawings. Realize the expression of the bridge elevation and section drawing between Party A and the designer through the two-dimensional plan, and realize the docking of the operation ...

AI Technical Summary

Problems solved by technology

However, for the construction and installation of spherical joints and the swivel process, the construction personnel are not familiar with and do not understand well.

In the construction process of the swivel spherical hinge, the spherical hinge engineer is required to carry out the installation steps and the monitoring accuracy of the important and difficult points, and there is a lack of a standardized installation guidance plan for the on-site pier of the spherical hinge components.
