Through careful organization, calculation and deduction, 3D modeling, Bim and other technical means are used to simulate splicing and hoisting on the computer, so as to escort the smooth construction on site with advanced technology.
Steel beam closure On the afternoon of October 30, with the last section of steel box girder accurately hoisted in place, the main line steel box girder of bid section I of Linyi Yihe road rapid transformation project (Qinghe West Road Wenquan Road) constructed by the company was successfully closed, marking the completion of the key node objectives of the project and laying a solid foundation for the main line of Yihe road.
give the thumbs-up!..
In this regard, the project department adopts the construction scheme of “factory segmented processing and on-site large-scale machinery + support installation”, and reasonable and rigorous preliminary preparations make the site compact and orderly.
The successful closure of the main line steel box girder of the project is another accumulation of the company’s construction experience in the field of steel box girder bridge, and also lays a foundation for the construction of subsequent ramp steel box girder in this bid section.
The main line steel box girder of section I of Yihe road rapid transformation project (Qinghe West Road Wenquan Road) is 167m long, two-way four lane, 25.1m wide bridge deck, 2800t total weight, 23m long maximum section, 84.7t weight and 12m hoisting height.
The main bridge crosses Yimeng South Road and crosses the tunnel, and the underground pipeline of the construction site is complex.
