Simultaneously activate the telescopic cylinders 20 on the two leading vehicles 16 and the telescopic cylinders 27 on the tail vehicle 24 to lift the load-bearing beam 17, thereby raising the Bailey beam 8 and detaching the left transverse main beam 7 and the right transverse main beam 7 to 75-10cm.

[0022] Current research hotspots are concentrated in three directions: Modular support node design based on BIM, such as sleeve bolt connection technology to improve overall performance, stress analysis system of Midas and Revit collaboration, and construction of a full life cycle data management platform.

[0023] In summary, BIM technology, through three-dimensional parametric design, multi-disciplinary collaboration, and numerical simulation, has become a core means to solve the design challenges of 40m ultra-high steel pipe column combined support, and has promoted bridge engineering into a new stage of digital construction.

One end of the load-bearing beam 17 is inserted into the lead vehicle telescopic cylinder 20, and the other end of the load-bearing beam 17 is inserted into the tail vehicle telescopic cylinder 27. The lead car telescopic cylinder 20 is equipped with a lead car load-bearing beam through rod 19, and the end of the lead car load-bearing beam through rod 19 passes through the interior of the load-bearing beam body 17. The tail car telescopic cylinder 27 is equipped with a tail car load-bearing beam through rod 26, and the end of the tail car load-bearing beam through rod 26 passes through the interior of the load-bearing beam body 17.

[0027] In this embodiment, a template is set above the steel pipe column combined support 3, and a cast-in-place box girder 1 is poured on top of the template.

[0028] This invention addresses key technical issues such as stability calculation and load transfer path optimization for ultra-high scaffolding (40m) through BIM parametric modeling and mechanical simulation, avoiding stress concentration risks that are difficult to detect in traditional two-dimensional design. Utilizing the three-dimensional collaborative characteristics of BIM, it simulates and verifies the feasibility of scaffolding erection schemes, predicts high-altitude operation risks, optimizes support system conversion processes, and reduces the risk of ultra-high scaffolding collapse. Furthermore, it directly generates processing drawings from the BIM model, reducing on-site welding, shortening the construction period, and lowering material waste and modification costs.

[0029] I. Parametric Modeling and 3D Refined Design Parametric 3D models of steel pipe columns, connection nodes, and support systems are created using BIM software such as Revit, enabling precise control over component dimensions and positioning. Collision detection is used to identify spatial conflicts (such as interference with adjacent pipelines or structures) in advance, allowing for optimization of the support structure's spatial layout.

[0030] Detailed modeling of steel pipe column nodes is performed to ensure the geometric accuracy of welded box sections and I-beam connectors, supporting complex stress requirements.

[0031] II. Mechanical Analysis and Structural Optimization Using finite element analysis software such as Midas, the stress simulation of the entire support structure was performed. By calculating the stress and strain under different working conditions (such as wind load and construction load), the stability of the steel pipe column and the reliability of the connection nodes were verified.

[0032] Based on the analysis results, the specifications of the members were optimized: the wall thickness of the steel pipes was adjusted, weak areas were strengthened (such as changing the position of the truss), and redundant materials were reduced to achieve lightweight design.

[0033] III. Construction Process Simulation and Work Process Collaboration Using 4D construction simulation technology, the process of scaffold erection, concrete pouring, and dismantling was dynamically simulated. The hoisting path and material turnover plan for Bailey beam 8 were simulated in advance, and construction risk points (such as safety gaps for high-altitude operations) were identified.

[0034] By integrating design and construction data through a BIM collaboration platform, the accuracy of process connections can be ensured (such as the coordinated installation of independent supports and adjustable steel beams).

[0035] IV. Standardized Component Library and Prefabricated Application Establish a standard component library for steel pipe columns, connectors, etc., to support rapid access and prefabricated design. Improve on-site assembly efficiency by clarifying prefabricated component processing information (such as welding process requirements) through model decomposition.

[0036] The objective of this invention is achieved as follows: First, based on the design drawings, a concrete structure model of the cast-in-place box girder 1 and the high pier column 2 is established using BIM software such as Revit. Then, a parametric 3D model of the steel pipe columns, connection nodes, and support system is established between the lower pier columns of the cast-in-place box girder 1 using BIM software such as Revit. Next, 4D construction simulation technology is used to dynamically simulate the scaffolding erection, concrete pouring, and dismantling process, and to pre-simulate the hoisting path and material turnover plan for the Bailey beam 8. Simulation reveals that the large amount of top-mounted scaffolding 10 used in traditional construction is due to insufficient boom extension of large cranes during scaffolding installation and dismantling. A scaffolding height of at least 3.5m is required to extend into the space under the box girder. To save materials... To measure the quantity, a pre-installed automatic jacking and lateral movement device 4 is used. After the top 10 disc-lock scaffolds are removed, the automatic jacking and lateral movement device 4 is used to move the Bailey beam 8 laterally, moving the Bailey beam 8 to under the flange of the box girder. This provides sufficient space for the crane to remove the Bailey beam 8, thus saving more than 2 meters of disc-lock scaffolding and reducing construction costs. Finally, by simulating the process of installing and dismantling supports for ultra-high, large curves, and high longitudinal slopes using traditional methods, it was found that high-altitude measurement and spatial positioning are difficult. Unmanned measurement technology can be used to feed the measurement data back to the data processing center, compare it with the model data to calculate the deviation value, and feed the deviation value back to the site for elevation correction to ensure that the elevation meets the requirements of the bridge's longitudinal and transverse slopes and the pre-camber of the box girder.

[0037] BIM technology offers a new approach to solving these problems: it enables the visual design of support structures through parametric modeling, optimizes the arrangement of members by combining finite element analysis, and integrates comprehensive inspection functions.

[0038] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
