【摘要】：2008年,國務院提出“力爭用兩年時間在36個大城市率先實現污水全部收集和處理”。按照蘭州市污染物減排的需要,2010年必須實現城區(qū)污水“全收集,全處理”的工作目標。目前,城市基礎設施建設投入不足,排水設施建設有所欠缺,城區(qū)排水管網與國家要求的有一定距離。截至2009年,蘭州四區(qū)共有排水管網656公里,其中上世紀80年代前的管網301公里,占全部管網的46%,這些管網存在陳舊老化,雨水污水不分流等問題,并且城市部分地區(qū)排水管網無覆蓋。蘭州正在組織實施的城區(qū)污水“全收集全處理”工程,需要建設357公里管網、五座污水提升泵站、三座污水處理廠,特別是今年要完成主體工程,工作量非常大,工期非常緊張。目前,在現有排水管道工程的理論基礎上,頂管施工探索出了新的施工工藝,在建筑物較多的大城市,管網鋪設工作通常需要頂管工程技術。本文以頂管施工技術為核心,結合我國排水管道施工工藝,頂管技術理論知識和實際經驗,借鑒了國內外對污水收集管道施工的研究成果,討論了管道施工過程中的設計和控制技術,運用了風險分析的相關知識,對頂管技術實施中的風險進行分析。主要成果如下:(1)通過研究排水管道工程的相關理論知識,分析了現有排水管道的施工工藝,對蘭州市污水全收集工程管道施工工藝進行確定,頂管施工法是蘭州市污水全收集工程管道施工工程的最佳選擇。(2)探討了頂管法的施工工藝的基本原理,由工具管或頂管掘進機、工作井和接收井、頂鐵、主頂裝置中繼站、基坑導軌、后座墻、頂進用管、輸土裝置、地面起吊裝置、測量及校正系統(tǒng)、注漿系統(tǒng)、供電及照明系統(tǒng)、通風與換氣系統(tǒng)和輔助施工等組成,每一個系統(tǒng)的相輔相成組成了排水管道工程。(3)為了保證施工過程的順利進行,我們對施工工藝及其施工過程進行了詳細的描述,并對施工中常見的問題及施工中的主要控制點進行了總結。在頂管技術施工過程中,施工人員要時刻注意導軌偏移、洞口止水圈撕裂或外翻、后靠背嚴重支形、位移或損壞、主頂油缸偏移及頂管機出洞防磕頭等問題。同時在施工過程中應十分關注減摩注漿、中繼間布置和工作坑的選取和設置等問題,以保證施工的準確度及效率。(4)結合國內外管道工程的相關經驗,對較多實際工程資料的收集,探討出施工過程存在地下不明管線及障礙物等風險,及其這種風險所造成的整個工程的停滯分析。主要分析污水全收集中所采用的施工技術,對頂管工程實施中延誤工期的各種風險因素進行了研究和分析,介紹了管道工程的應用及其對環(huán)境的影響進行分析,為以后頂管施工提供了借鑒。
[Abstract]:In 2008, the State Council proposed to "strive to take the lead in 36 major cities in two years to achieve all sewage collection and treatment." According to the need of pollutant emission reduction in Lanzhou City, the goal of "full collection and treatment" of urban sewage must be realized in 2010. At present, the construction of urban infrastructure is insufficient, the construction of drainage facilities is deficient, and the urban drainage network has a certain distance from the requirements of the state. As of 2009, the four districts in Lanzhou have a total of 656 km of drainage networks, of which 301 km were before the 1980s, accounting for 46% of the total pipe networks. These networks are old and aging, and Rain Water sewage is not diverted. And part of the city drainage pipe network without coverage. Lanzhou is organizing and implementing the urban sewage "total collection and full treatment" project, which requires the construction of 357 kilometers of pipe networks, five sewage lifting pumping stations, and three sewage treatment plants, especially the major projects to be completed this year. The workload is very large. The time limit is very tight. At present, on the basis of the theory of drainage pipe engineering, a new construction technology has been explored in pipe jacking construction. Pipe jacking engineering technology is usually required for pipe network laying in large cities with more buildings. Based on the pipe-jacking construction technology, combined with the construction technology of drainage pipeline in China, the theoretical knowledge and practical experience of pipe-jacking technology, the research results of sewage collection pipeline construction at home and abroad are used for reference in this paper. This paper discusses the design and control technology of pipeline construction and analyzes the risk in the implementation of pipe jacking technology by using the relevant knowledge of risk analysis. The main results are as follows: (1) by studying the relevant theoretical knowledge of the drainage pipeline project, the author analyzes the construction technology of the existing drainage pipeline, and determines the pipeline construction technology of the total sewage collection project in Lanzhou. Pipe jacking construction method is the best choice of pipeline construction project in Lanzhou sewage collection project. The basic principle of pipe jacking method is discussed. The pipe jacking roadheader, working well and receiving well, top iron and main roof device relay station are used. Foundation pit guide rail, backseat wall, jacking pipe, earth conveyer, ground lifting device, measurement and correction system, grouting system, power supply and lighting system, ventilation and ventilation system and auxiliary construction, etc. In order to ensure the smooth progress of the construction process, we describe the construction technology and its construction process in detail. The common problems in construction and the main control points in construction are summarized. During the construction of pipe jacking technology, the constructors should always pay attention to the deviation of the guide rail, tear or roll out of the sealing ring of the hole, the serious back of the back, displacement or damage, the displacement of the main oil cylinder and the prevention and kowtowing of the pipe jacking machine. At the same time, in order to ensure the accuracy and efficiency of construction, we should pay close attention to the problems of anti-friction grouting, relay layout and selection and setting of working pits in order to ensure the relevant experience of pipeline engineering at home and abroad, so as to ensure the accuracy and efficiency of construction. Based on the collection of more practical engineering data, it is discussed that there are some risks in the construction process, such as underground pipelines and obstacles, and the analysis of the stagnation of the whole project caused by this kind of risk. This paper mainly analyzes the construction technology used in the total collection of sewage, studies and analyzes various risk factors of the delay in the implementation of pipe jacking project, and introduces the application of pipeline engineering and its impact on the environment. It provides reference for pipe jacking construction in the future.
