- Abstract:
- With the development of cities, the social problems caused by the aging of underground pipelines are becoming increasingly prominent. The surface traffic congestion and the complexity of pipelines make the open cut pipe replacement a problem to be solved urgently. Taking the raw water pipeline repair project from Bijiashan waterworks to Donghu waterworks as an example, this paper studies the trenchless construction method of steel pipe under the condition of long-distance curve based on BIM technology and 3D scanning. With the help of 3D scanning and BIM technology, it realizes the spatial positioning of raw water pipeline, the optimal well location layout and pipe joint length setting, the special socket interface to meet the curvature requirements of the original pipeline. The actual construction process shows that the application of this technology greatly reduces the number of working wells, reduces the influence of pipeline relocation and traffic, and achieves good economic and social benefits.
