Positioning construction method for multi-box single-chamber steel bars and corrugated pipes assisted by BIM technology

Abstract

The invention provides a positioning construction method for multi-box single-chamber steel bars and corrugated pipes assisted by BIM technology. The method comprises the following steps of S1, firstly, performing technical preparation before construction, and performing drawing review; S2, making a modeling rule according to the drawing, and performing modeling by utilizing Revit software according to the modeling rule; S3, adopting Navisworks software to simulate construction, check collisions and improve a model ; S4, drawing a design drawing according to the perfected model, and compilinga construction scheme according to the design drawing; S5, carrying out technical disclosure on the field management personnel and the operation teams by the scheme compilation personnel or the BIM engineer; S6, enabling on-site managers and operation teams to machine conduct steel bars, install steel bars and lay the corrugated pipes according to technical disclosure. Construction is made according to a planned procedure, corrugated pipe positioning ribs are welded in the steel bar mounting process, corrugated pipe laying space is reserved, corrugated pipe unimpeded laying is achieved, the construction efficiency is greatly improved, and forced moving or steel bar cutting-off caused by the position in the construction process is avoided.

Description

technical field [0001] The invention relates to the technical field of steel bar construction for roads and bridges, in particular to a positioning construction method for multi-box single-chamber steel bars and corrugated pipes assisted by BIM technology. Background technique [0002] The prestressed concrete box girder system of multi-box, single-chamber and equal girder with high inclined web is especially common in the design of urban wide-width road bridges. The prestressed concrete box girder of the No. 0 block on the bridge pier top of this system is connected by cast-in-place beams, so that the No. 0 block is horizontally The span is large. In order to meet the requirements of the structural safety level, the steel bars are often arranged densely. The bellows (prestressed steel bars) are criss-crossed. The web of the box girder, steel bars, and corrugated pipes (prestressed steel bars) are large in size, complex in structure, and difficult to install. [0003] The i...

Problems solved by technology

[0004] In view of the dense and complex design of steel bars in the current road and bridge construction process, collision problems often occur. When the bellows are laid after the steel bars are installed, they often collide with the steel bars because the steel bars occupy their spatial positions, resulting in failure to lay smoothly. Traditional construction needs to be reworked. , Forcibly moving or cutting off the technical problem of reinforcing steel bars, this invention proposes a BIM technology-assisted multi-box single-chamber steel bar and bellows positioning construction method
