1、conferences, learned superiors policies; reports, you can learn to deal with problems, art, just wanted to learn, to learn at any time. To continuously expand the scope of the study. The complexity and comprehensiveness of our work, decided to not only do we want to be professionals, or if generalis2、ts, to dabble in different areas of knowledge. Mastery of knowledge not only to have knowledge to rational analysis. This on requirements we, not only to learning national of route, and approach, and policy, also to learning national of legal, and regulations; not only to with political theory armed3、 mind, also to with economic theory guide work; not only to read history, also to read history; not only to absorption SM of mirror, also to gets is of road; not only to from local learn, also to to outside learn; not only to to books learn, also to field study learn. Therefore, I would encourage yo4、u, and more to the outside world when I have time to take a look at, take a stroll, outside developments, learn other peoples development approach, and then come back to guide our work. Second, we must think. Learning without thought to overshadow, thinking without learning is perilous. We want to f5、oster the character of advancing with the times, forge ahead, often reflect themselves in adapting to the new situation on whether there are delays, have anything to fear in the reform and innovation, whether in terms of accelerating the development of a relaxation, keep promising State of mind. In 6、order to do investigations, investigations is the road to heaven, God disposes of the base. To wants to real heard truth, and justice to truth, and get truth, received effectiveness, on must in-depth actual, and outreach, and in-depth masses, worship masses for Division, and masses heart, with masse7、s with discussion everyone care of problem, listening they of calls, understand they of mood, feel they of suffering, summary they of experience, concentrated they of wisdom, especially on masses most hope, and most urgent, and most worries, and most complained of hot, and difficulties and focus pro8、blem, more to active research, caught not put. Dare to innovate, in our work, often remain the old way doesnt work, the new approach would not situation, the reason, the key is that many people know that copying other peoples ideas, mechanically, using someone elses old ways. To change this predicam9、ent, requires us to break the shackles of traditional concepts to overcome conservative, conformist, good at finding new problems and to accept new things, summarize new experience, new ideas, developing new programmes and Maverick, a new approach to solve problems, speed up development. Especially 10、in implement superior policy spirit of process in the, both implementation, and cannot mechanically, to to extraordinary of courage and develop enterprising of spirit, put flexibility and principle combined up, put superior of spirit and local reality combined up, Yong conspiracy to breakthrough of 11、policy, and exercise innovation of lift, developed out development works of, and grass-roots welcomes of, and大連開發區熱電廠鍋爐本體保溫施工方案本體保溫施工方案一、編制依據:1.1工業設備及管道絕熱工程質檢評定標準GB50185-93。1.2電力建設施工及驗收技術規范1.3電力建設安全工作規程(火力發電廠)DL5009.1-2002。二、作業任務2.1鉤釘、骨架焊接安裝;2.2保溫棉層安裝2.3外保護層安裝;2.4以上三項施工內容詳見(四)施工方法及作業程序。三、作業準備及工作條件3。12、1 作業人員的資格要求、勞動力組織項目負責人 1 人作業組長 2 人 技術員 1 人電焊工 2 人質檢員 1 人保溫工 30 人3.2 施工機械及工器具準備序號名稱單位數量備注1剪板機臺12壓線機臺13咬口機臺14卷板機臺15鐵皮剪刀把206拉鉚槍把307平板直尺個38拐尺個39手電鉆把1010刀據把1511起重滑輪個312棕繩米30013手鉗把1514電焊機臺415切割機臺183.3 作業環境條件a。施工圖紙和技術資料齊全,并且經過會審無變更,作業指導書已編制,開工手續已辦。b.與保溫有關的鋼結構工程施工完畢,并驗收合格。c。及時掌握材料到貨情況,應滿足施工進度的需求,領到的材料要隨時用完,13、有剩余材料存入自備材料庫,現場不得長久堆放.四、作業方法及施工要求4.1 作業措施及方案 a。由施工技術員根據圖紙以及相關資料要求,向施工人員進行交底,施工人員應細心聽講,認真理解,并進行討論作到確無疑問后,方可辦理技術交底簽證。b。保溫施工1)對設備系統表面塵土、雜物等進行徹底清理后方可進行下一道施工工序。2)施工前對保溫材料的理化性能,出廠文件以及試塊進行檢驗,合格后簽證(對于不合格的材料,不準使用),材料運送一般,采用卷揚機、尼龍繩穿定滑輪、人背三種方法.保溫材料(高處運送要用網或花格布包扎運送)。3)腳手架搭設必須由專職人員進行,嚴格執行腳手架搭拆質量要求,設投好后,并經安檢職能部門驗14、收合格方可使用。4)支撐角鋼骨架安裝,先在設備平面進行劃線,并找出支撐角鋼位置,由專職焊工施焊,把支撐角鋼垂直焊接在設備表面(支撐角鋼(40403)間距,橫向500mm,縱向1000 mm),然后焊接連接角鋼.5)自鎖墊片拉桿Q235-A焊接布置,由于拉桿為設備帶材不須現場彎制,焊接前在設備表面標準劃線,并劃出鉤釘具體位置,鉤釘間距為350 mm見方,采用梅花形結構布置。然后將拉桿點焊其上,施工順序由上而下,要求點焊牢固、美觀、橫平、豎直(每平方米不少于8個)。6)保溫層鋪設保溫層施工時,單層鋪設應錯縫,雙層鋪設錯縫距離不小于保溫棉板長或板寬的三分之一,縫間拼接整齊嚴密,不許有任何空洞、縫隙現15、象,設備接角要錯接固定、牢固。法蘭、三通、彎管等處的保溫采用可拆卸式結構,保溫層緊貼于設備形體表面,用鐵絲兩道或多道綁緊、扎實。同樣要求單層錯縫雙層壓縫,縫間填充密實,法蘭處要留有足夠可拆卸螺栓的距離,伸縮節、補償器處要按照膨脹方向留出距離。主保溫層施工應單層錯縫,雙層壓縫,縫間填充密實,接縫拼接整齊無縫隙。保溫層敷設完畢后,用自鎖墊片,穿拉桿壓緊,使保溫層緊貼設備表面,然后將自鎖墊片之外的拉桿端部向上折90角,卡住墊片。7)保護層施工該項工程采用波形鋁板和鋁合金板做保護層,安裝時把金屬護殼緊貼在管道保溫層外面,把兩邊接縫搭接在一起,敲打咬接,搭接重疊部分不小于50mm,用手提電鉆鉆孔,自攻螺16、釘固定.自攻螺釘間距約200mm,每道縫不得少于4個釘。接縫應嚴密、平整、處于隱蔽位置,水平管道的縱向接縫應設置管道側面,水平管道的環向接縫應按管道坡度高搭低茬,垂直管道的環向接縫應上搭下茬。保護層施工H24.2 質量及工藝保證措施a.工程質量檢驗及評定標準1)施工質量必須符合圖紙設計要求。2)評定標準執行工業設備及管道絕熱工程檢驗評定標準GB5018593,電力建設施工及驗收規范。B關鍵檢查項目,隱蔽工程及停工待檢點的確定:1)停工待檢H2)對H點的控制,H點即是對主保溫層施工的控制,本工序是保溫工程施工的中心環節,也是保溫重點與難點,保證H點的控制關鍵有兩個方面,首先施工方法應正確,在保證17、保溫質量的情況下,對保溫材料的檢驗是否合格也是關鍵之一,第二是對施工質量把關,如無錯縫、壓縫,應進行整改,如有拼砌不嚴,必須用填料將其填充密實且平整,直至符合設計規范要求為止.3)對波形鋁板外保護的控制,首先不得使用明顯缺陷的材料,下料應準確,接縫應嚴密、平整,所有外保護缺陷應全部消除.C質量要求及質理保證措施1)要求各分項工程施工重點,都必須有自檢記錄。2)要求各分項工程施工技術記錄3)鉤釘、骨架安裝驗收簽證。4)主保溫層砌筑,保溫層驗收簽證.5)各分項保溫工程驗收簽證。6)每道工序必須有驗收簽證才能進行下一道工序,否則視為違章作業.五、作業質量標準及檢驗要求a 施工中的作業標準和檢驗要求必18、須按照火電建設施工、驗收及質量評定標準進行。B 在施工過程中,應做好原始的施工記錄。六、職業安全健康與環境管理6.1 脫硫保溫主要危險辨識作業活動危險因素可能導致的事故相應措施電動工機具使用砂輪片斷裂砂輪片飛出傷人根據說明書正確使用,施工時不能正對著人設備堆放、清理安全通道不足,捆扎不牢劃落人員損傷進行設備堆放、清理時,應有序、牢靠電焊機焊接接地不正確,不牢固 人員觸電,設備損壞安排專人監護,用專用地線且連接牢固,不施工時關掉焊機電源腳手架作業高空墜落物體打擊人員、設備損傷嚴格按照國家規范搭建腳手架。6。2 安全注意事項a. 進入施工現場,必須著裝整齊,戴安全帽,高處作業必須系安全帶。b。 施19、工中必須嚴格遵照中華人民共和國安全生產法相關規定執行,認真學習并嚴格執行電力建設安全工作規程(火力發電廠)DL5009.12002及工藝要求中的有關規定,嚴禁違章作業。c。 認真執行安全技術交底制度,每個施工人員應了解安全技術交底注意事項.6.3 施工安全措施a.施工人員必須熟悉并掌握電力建設安全工作規程(火力發電廠)DL5009。1-2002的有關規定。b。施工人員必須經過三級安全教育并考試合格方可上崗。c。施工人員進入施工現場必須正確佩戴安全帽,并系緊帽帶,高空作業時必須系好安全帶。d.高空作業時,大件工器具要系有安全繩,小件工器具要放在工具袋內,并放置在安全可靠的地方,小件材料要用鐵絲扎20、牢,防止墜落。e。使用直梯時與地面水平夾角以60為宜,并有防滑和防傾倒措施。f.電動工具在使用前要仔細檢查,確保其性能良好,并有良好的漏電保護裝置.g。腳手架搭拆腳手架必須由專業人員搭拆,并經施工部門和使用部門驗收合格后方可使用,認真執行腳手架搭拆安全措施.搭設腳手架用腳手桿,跳板等材料要仔細檢查,不得有破損,腳手架要綁扎牢固,上桿離地應有1.05米的防護欄桿及18CM高的擋腳板或防護立網,腳手架載荷不得超過270Kg/m,木跳板兩端8CM處應用鍍鋅鐵絲箍繞23圈或用鐵皮釘實。h.用電動工具作業時,必須佩戴防護眼鏡,必要時戴上防護罩,電動工具插在插座上。i.在高空作業時,電焊線不允許碰到作業使21、用的腳手架防止電焊線漏電發生事故。高空作業傳遞工器具和材料時,不允許拋擲.應用繩系牢傳遞。j。嚴禁酒后進入施工現場。(附有安全管理體系圖)k工程全部結束后,要做到“工完 料凈 場地清”,做到安全文明施工,樹立企業形象,打出企業品牌。6.4 文明施工要求a.施工過程中,施工人員必須著裝整齊,佩戴標志。b。工作中所有工作電源必須規范,不允許亂搭亂接。c.施工現場嚴禁吸煙,嚴禁酒后上班。d.做到“工完 料盡 場地清”.附圖:安全管理體系圖 負責人代民法責任人代小濤安全員張東生安全員胡紅領埋地部分整根敷設不允許有接頭。地上一層至四層為低區,由小區室外給水管網直接供水,地上五層至十六層為中區,由小區中區22、變頻調速泵組供水,地上十七層至三十三層為高區,由小區高區變頻調速泵組供水。According to Office Party of mass line education practice activities led group of unified arrangements, units main led to for cadres workers Shang a times party lecture, due to himself level limited, only put this stage concentrated learning of experience today a23、nd everyone common with learning exchange, purpose is let we further deep understanding mass line of connotation, insisted party of mass line, do masses work, following main from four a aspects told: a, and full awareness party of mass line education practice activities of major meaning Partys 18 ma24、jor distinct proposed to focus on the partys advanced nature and purity, in the party, with pragmatic and clean for the people as the main content of the partys mass line and educational practice. This is comrade XI Jinping as party General Secretary and adhere to strictly administering the party, s25、trengthen the partys major decision is in line with the public expectations and strengthening the construction of learning-oriented service innovation of Marxist partys major deployment, is the important measure to advance the great cause of socialism with Chinese characteristics. First, carry out t26、he partys mass line in education practice, was carrying 18 of the party spirit, summon a powerful force for realizing the great rejuvenation of the Chinese nation the Chinese dream of urgent needs. Partys 18 to promote strategic deployment to building socialism with Chinese characteristics, presents27、 two 100-year goal, namely, by 2020 Chinas gross domestic product and per capita income of urban and rural residents in 2010 on the basis of double complete the building of a well-off society; the middle of this century into a prosperous, democratic, civilized and harmonious Socialist modern country28、, and on this basis, the Chinese dream of realizing the great rejuvenation of the Chinese nation. 18 Congress of the party, Comrade XI Jinping repeatedly expounded the Chinese dream.
