【摘要】:近年來,隨著城市建設(shè)方式由粗放式向高效集約式轉(zhuǎn)變,城市土地開發(fā)模式由粗放式開發(fā)向挖掘潛存量空間轉(zhuǎn)變,空間開發(fā)利用由地上轉(zhuǎn)向地上地下空間相結(jié)合,綜合管廊得到人們的廣泛關(guān)注。綜合管廊是一項(xiàng)非常復(fù)雜的工程,業(yè)內(nèi)普遍認(rèn)為其全生命周期的理想模式應(yīng)該是采用BIM+GIS+物聯(lián)網(wǎng)。本文初步探討了其中的BIM+物聯(lián)網(wǎng)部分的技術(shù)問題,具體展開了以下兩方面研究:(1)綜合管廊的BIM建模研究。綜合管廊是一種修建于城市地下將電力電纜、通信電纜、燃?xì)夤艿、熱力管道、給排水管道、油氣管道等集于一體的空間結(jié)構(gòu),涵蓋眾多專業(yè)。傳統(tǒng)的綜合管廊多采用二維設(shè)計(jì),存在很多缺陷,比如:管線頻繁穿插造成的連鎖碰撞反應(yīng)、施工人員對(duì)設(shè)計(jì)方案的錯(cuò)誤理解等,因此本文針對(duì)傳統(tǒng)二維設(shè)計(jì)的局限性提出了綜合管廊的BIM建模研究。這部分詳細(xì)分析了建筑信息模型(BIM)的全生命周期應(yīng)用,并重點(diǎn)介紹了BIM在綜合管廊規(guī)劃設(shè)計(jì)階段的應(yīng)用,最后利用Autodesk Revit軟件搭建了某綜合管廊的三維模型。(2)綜合管廊的無線監(jiān)測系統(tǒng)研究?紤]到綜合管廊容納管線種類多,特別是燃?xì)夤芫納入管廊后極易因燃?xì)庑孤┮l(fā)火災(zāi)爆炸事故,而且發(fā)生事故時(shí)管廊有線監(jiān)測系統(tǒng)可能出現(xiàn)故障而無法正常工作。因此,本文站在第三方的立場(如:政府監(jiān)管機(jī)構(gòu)、日常移動(dòng)巡檢機(jī)構(gòu)等),開發(fā)了基于無線傳感器網(wǎng)絡(luò)(WSN)的便攜式移動(dòng)監(jiān)測系統(tǒng),對(duì)綜合管廊中的溫度、濕度、甲烷濃度、硫化氫含量、氧氣含量進(jìn)行實(shí)時(shí)監(jiān)測。這部分詳細(xì)介紹了監(jiān)測系統(tǒng)的總體架構(gòu)、硬件選型、硬件設(shè)計(jì)與軟件設(shè)計(jì);討論了無線節(jié)點(diǎn)在綜合管廊中的部署問題;最后借用綜合管廊天然氣艙室的物理模型進(jìn)行了測試實(shí)驗(yàn)。以上兩部分的研究都具有實(shí)際應(yīng)用價(jià)值,綜合管廊的BIM模型為后期施工建設(shè)提供了重要依據(jù),無線監(jiān)測系統(tǒng)實(shí)現(xiàn)了綜合管廊內(nèi)的環(huán)境監(jiān)測,可保證管廊安全穩(wěn)定運(yùn)行?傮w來講,本文關(guān)于綜合管廊的BIM建模與監(jiān)測系統(tǒng)的研究為后續(xù)實(shí)際工程應(yīng)用奠定了理論基礎(chǔ)。
[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.
