【摘要】：近年来,随着城市建设方式由粗放式向高效集约式转变,城市土地开发模式由粗放式开发向挖掘潜存量空间转变,空间开发利用由地上转向地上地下空间相结合,综合管廊得到人们的广泛关注。综合管廊是一项非常复杂的工程,业内普遍认为其全生命周期的理想模式应该是采用BIM+GIS+物联网。本文初步探讨了其中的BIM+物联网部分的技术问题,具体展开了以下两方面研究:(1)综合管廊的BIM建模研究。综合管廊是一种修建于城市地下将电力电缆、通信电缆、燃气管道、热力管道、给排水管道、油气管道等集于一体的空间结构,涵盖众多专业。传统的综合管廊多采用二维设计,存在很多缺陷,比如:管线频繁穿插造成的连锁碰撞反应、施工人员对设计方案的错误理解等,因此本文针对传统二维设计的局限性提出了综合管廊的BIM建模研究。这部分详细分析了建筑信息模型(BIM)的全生命周期应用,并重点介绍了BIM在综合管廊规划设计阶段的应用,最后利用Autodesk Revit软件搭建了某综合管廊的三维模型。(2)综合管廊的无线监测系统研究。考虑到综合管廊容纳管线种类多,特别是燃气管线纳入管廊后极易因燃气泄漏引发火灾爆炸事故,而且发生事故时管廊有线监测系统可能出现故障而无法正常工作。因此,本文站在第三方的立场(如:政府监管机构、日常移动巡检机构等),开发了基于无线传感器网络(WSN)的便携式移动监测系统,对综合管廊中的温度、湿度、甲烷浓度、硫化氢含量、氧气含量进行实时监测。这部分详细介绍了监测系统的总体架构、硬件选型、硬件设计与软件设计;讨论了无线节点在综合管廊中的部署问题;最后借用综合管廊天然气舱室的物理模型进行了测试实验。以上两部分的研究都具有实际应用价值,综合管廊的BIM模型为后期施工建设提供了重要依据,无线监测系统实现了综合管廊内的环境监测,可保证管廊安全稳定运行。总体来讲,本文关于综合管廊的BIM建模与监测系统的研究为后续实际工程应用奠定了理论基础。
[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.
