基于BIM模型的綜合管廊監(jiān)測系統(tǒng)研究
[Abstract]:In recent years, with the transformation of urban construction mode from extensive to high-efficiency intensive, urban land development mode from extensive development to mining latent storage space, space development and utilization from the aboveground to the aboveground and underground space combined. The integrated pipe gallery has received extensive attention. The integrated pipe gallery is a very complex project, and it is generally agreed that the ideal model for its entire life cycle should be the BIM GIS Internet of things. In this paper, the technical problems of the BIM Internet of things are discussed, and the following two aspects are studied: (1) the BIM modeling of the integrated pipe gallery. Integrated pipe gallery is a kind of space structure built in the city underground, which integrates power cable, communication cable, gas pipeline, thermal pipeline, water supply and drainage pipeline, oil and gas pipeline and so on, covering many specialties. The traditional integrated pipe gallery is usually designed in two dimensions, which has many defects, such as the interlocking collision reaction caused by frequent pipe-through, the wrong understanding of the design scheme by the constructors, etc. In this paper, the BIM modeling of integrated pipe gallery is proposed in view of the limitation of traditional two-dimensional design. In this part, the application of building information model (BIM) in the whole life cycle is analyzed in detail, and the application of BIM in the planning and design of integrated plumbing corridor is emphasized. Finally, the 3D model of an integrated pipe gallery is built by using Autodesk Revit software. (2) the wireless monitoring system of the integrated pipe corridor. Considering that there are many types of pipeline in the integrated pipe gallery, especially when the gas pipeline is included in the pipe corridor, it is easy to cause fire and explosion accidents due to gas leakage, and the cable monitoring system of pipe gallery may fail to work normally when the accident occurs. Therefore, in the position of the third party (such as government supervision agency, daily mobile inspection organization, etc.), this paper develops a portable mobile monitoring system based on wireless sensor network (WSN), which is applied to the temperature, humidity, methane concentration in the integrated pipe gallery. The content of hydrogen sulfide and oxygen were monitored in real time. In this part, the overall architecture, hardware selection, hardware design and software design of the monitoring system are introduced in detail, and the deployment of wireless nodes in the integrated pipe gallery is discussed. Finally, the physical model of the natural gas compartment of the integrated pipe gallery is used to carry out the test experiment. The above two parts of the research have practical application value, the BIM model of the integrated pipe corridor provides important basis for the later construction, the wireless monitoring system realizes the environmental monitoring in the integrated pipe corridor, which can ensure the safe and stable operation of the pipe gallery. In general, the research on BIM modeling and monitoring system of integrated pipe gallery lays a theoretical foundation for subsequent practical engineering application.
