Application of BIM in Underground Continuous Wall

Building Information Modeling (BIM) is the direct application of information technology in the construction industry. It has many advantages such as shared API data interfaces, high data integration, data consistency, data relevance and construction demonstration functions. It has been widely used and achieved remarkable results. In the 21st century, the development trend of Beijing city is to develop towards the sky and underground. Especially in the past ten years, with the increase of high-rise and super high-rise buildings in Beijing, and the booming development of subway construction. The underground continuous wall is a construction technology with very high use value whether it is used as the main body (or part of the main body) of the underground structure or as a waterproof and soil retaining facility during construction. However, in the Beijing area, the underground diaphragm wall (depth greater than 40 meters, width greater than or equal to 1.2 meters) due to the difficulty of the project, complex technology, and many construction problems, the relevant design and construction experience is less, and the relevant technical talents are scarce. The purpose of this article is to study the application of BIM in underground continuous walls. This article is based on the Microsoft Visual Studio 2017 development platform, based on the Visual C# programming language, using the API data interface provided by the Revit 2018 software, based on the built BIM model, for engineering quantity statistics, collision checking, drawing output, collaborative work and construction models. Wait for operations to show the application of BIM technology in the underground continuous wall. Experiments show that the use of the collision detection function of BIM technology can not only reasonably arrange pipelines, but also adjust the positions of brackets, buttresses and other components to facilitate the on-site installation of pipelines. The use of BIM technology can simulate the hoisting of the pipe gallery, find out the collision points in the hoisting process, and improve the hoisting plan.
