【摘要】：隨著中國城市化建設(shè)水平的不斷提高,我國生活生產(chǎn)供水方面的問題越來越嚴(yán)重。突出表現(xiàn)在城市供水水源過于單一化,供水風(fēng)險不斷加大,同時不少鄉(xiāng)鎮(zhèn)區(qū)域存在飲用水質(zhì)量不達(dá)標(biāo)、水源污染嚴(yán)重等問題,嚴(yán)重影響社會主義建設(shè)事業(yè)的發(fā)展和人民生活質(zhì)量的提高。為了解決供水問題,改善供水體系,不少城市和鄉(xiāng)鎮(zhèn)開始興建或正在籌劃建設(shè)、完善當(dāng)?shù)氐妮斔こ添?xiàng)目,使得輸水工程成為現(xiàn)代化城市建設(shè)事業(yè)的重要工作。所以,根據(jù)國內(nèi)水資源分布狀況與當(dāng)前供水管網(wǎng)系統(tǒng)的基本情況與利用效率,對地區(qū)性供水系統(tǒng)中最關(guān)鍵、資金投入最多的輸水管網(wǎng)系統(tǒng)的建設(shè)進(jìn)行深入研究分析,尤其是建設(shè)過程中大口徑管道的利用細(xì)節(jié)和重點(diǎn)加大研究力度具有十分積極的意義。研究的主要內(nèi)容集中在大口徑管道穿越高速公路、河流、鐵路等有障礙地段,通過對多種施工方案進(jìn)行對比的方式,對大口徑管材、管徑、接口方式、管道腐蝕和調(diào)節(jié)構(gòu)筑物等關(guān)鍵點(diǎn)的分析研究,總結(jié)大口徑管道在長距離輸水工程中的應(yīng)用經(jīng)驗(yàn),為更多區(qū)域性供水系統(tǒng)建設(shè)的安全性、經(jīng)濟(jì)性、可靠性提供一定的參考意義,這也是本文研究工作的實(shí)踐意義。本文結(jié)合引青濟(jì)秦擴(kuò)建三期工程,從大口徑水輸水工程項(xiàng)目的設(shè)計和施工的關(guān)鍵環(huán)節(jié)來分析大口徑管道在引青濟(jì)秦擴(kuò)建三期工程項(xiàng)目施工中的具體應(yīng)用細(xì)節(jié),就引青濟(jì)秦工程項(xiàng)目大口徑輸水管道在克服高速公路、鐵路等交通設(shè)施障礙、河流山脈等自然環(huán)境阻礙的具體應(yīng)用方法與經(jīng)驗(yàn)等一系列要點(diǎn)進(jìn)行論述,對架空管、沉管、頂管、拉管(非開挖定向鉆)等重要細(xì)節(jié)進(jìn)行分析,展現(xiàn)出一個合理的、可實(shí)施性非常強(qiáng)的設(shè)計和施工方案。在此基礎(chǔ)上本文又對長距離大口徑輸水工程項(xiàng)目中的并網(wǎng)調(diào)試工作細(xì)節(jié)進(jìn)行了經(jīng)驗(yàn)性總結(jié),為大口徑輸水管道在長距離輸水工程項(xiàng)目中的高效應(yīng)用提供參考,確保我國各地供水系統(tǒng)的安全性與穩(wěn)定性。本文研究所得結(jié)果來看,大口徑輸水管道在長距離輸水工程項(xiàng)目中具有較強(qiáng)的應(yīng)用價值,加大對大口徑輸水管道的研究力度對我國輸水工程項(xiàng)目具有重要意義。
[Abstract]:With the development of urbanization in China, the problems of water supply in domestic production are becoming more and more serious. At the same time, many township areas have problems such as drinking water quality is not up to standard, water pollution is serious, which seriously affects the development of socialist construction and the improvement of people's quality of life, in order to solve the water supply problem. To improve the water supply system, many cities and towns began to build or are planning to build, improve the local water transmission projects, so that the water transfer project has become an important work of modern urban construction. According to the distribution of domestic water resources and the basic situation and utilization efficiency of the current water supply network system, the construction of the water pipeline network system, which is the most critical and the most invested in the regional water supply system, is deeply studied and analyzed. In particular, the use of large-caliber pipeline in the process of the use of details and focus on the study has a very positive significance. The main content of the study focused on the large-caliber pipeline crossing the highway, rivers. Railway and other obstructed areas, through the comparison of various construction schemes, the analysis and study of the large caliber pipe, pipe diameter, interface mode, pipeline corrosion and regulation of the structure and other key points. The application experience of large-caliber pipeline in long-distance water conveyance project is summarized, which provides a certain reference for the safety, economy and reliability of more regional water supply system construction. This is also the practical significance of the research work in this paper. From the key links of the design and construction of the large-caliber water conveyance project, this paper analyzes the concrete application details of the large-caliber pipeline in the construction of the third phase of the project of diversion from Qingjin-Jiqin extension. This paper discusses a series of key points in overcoming the obstacles of highway, railway and other transportation facilities, and the concrete application methods and experiences of the natural environment hindrance such as rivers and mountain ranges in the large-caliber water conveyance pipeline of the project leading to Qingqing-Ji-qin project. The important details such as overhead pipe, sinking pipe, jacking pipe and pulling pipe (non-excavated directional drill) are analyzed, showing a reasonable. On the basis of this, this paper summarizes the details of grid-connected debugging in long distance and large caliber water conveyance project. This paper provides a reference for the efficient application of large caliber water conveyance pipeline in long distance water conveyance project, and ensures the safety and stability of water supply system in various parts of our country. The large caliber water conveyance pipeline has strong application value in the long distance water conveyance project. It is of great significance to increase the research intensity of the large caliber water conveyance pipeline for the water conveyance project of our country.
