施工現(xiàn)場的臨時照明.場內交通及水電設施施工安全技術交底.doc

交底內容   施工現(xiàn)場的臨時照明   室內照明線路應用瓷夾固定。電線接頭應牢固，并用絕緣膠帶包扎。保險絲應用電負荷量裝設。能產行大量蒸汽、氣體、粉塵等工作場所，應使用密閉式電氣設備。有爆炸危險的工作場所應使用防爆型電氣溫設備。電氣設備的傳動帶、轉輪、飛輪等外露部位必須安設防護罩。檢修電氣設備時應按下列要求進行：電氣設備的檢修必須由電工進行，他人不得任意操作；工作中如遇停電拉下開關，切斷電源，檢修結束必須仔細檢查各項設備的情況，沒有異常，方可合閘。大型電氣設備檢修應在切斷電源、設好防護后進行，并在開關處設置警示標牌，工作完成后方可拆除，如需進行送電試驗時，必須在認真檢查并與有關部門聯(lián)系后，方可進行。大型橋梁施工現(xiàn)場，隧道和預制場地，應有自備電源，以免因電網停電造成損失和出現(xiàn)事故，自備電源和電網之間，要有聯(lián)鎖保護。
場內交通及水電設施  場內道路應經常維護，保持暢通。載重車輛通過較多的道路，其彎道半徑一般不小于15m，特殊情況不得小于10m，手推車道路的寬度不小于1.5m。急彎及陡坡地段應設置明顯交通標志，與鐵路交叉處應有專人照管，并設信號裝置和落桿�？拷�河流和陡壁處的道路，應設置護欄和明顯警告村志。場內行駛斗、平車的軌道應平坦順直，縱坡不得大于3%。車輛應裝制動閘，鐵路終點應設置倒坡和車檔。生產生活用水應進行鑒定，其水質必須符合國家現(xiàn)行標準。水源應采取保護措施，防止水質污染。場內加設架設的電線應絕良好，懸掛高度及線間距必須符合電業(yè)部門的安全規(guī)定�，F(xiàn)場架設的臨時線路必須用絕緣物支持，不得將電線纏在鋼筋、樹木或腳手架上。電工在接近高壓線操作時，其安全距離為：10kv以下不得小于0.7m,20~35kv 不得小于1m,44kv不得小于 1.2m，否則必須停電后方可操作。各種電器設備應配有專用開關，室外使用的開關、插座外裝防水箱并加鎖，在操作處加設絕緣墊層。在三相四線制中
Clarification at the construction site of the contents of the provisional application of porcelain lighting indoor lighting clip fixed lines. Wire connector should be firmly, and wrap with insulating tape. Application of electric load fuse installed. Nengchan line a lot of steam, gas and dust in the workplace, should be used enclosed electrical equipment. An explosive hazard in the workplace should use explosion-proof type electric temperature equipment. Electrical equipment belts, wheel, flywheel and other exposed parts must be fortified security guard. Maintenance of electrical equipment according to the following requirements: Electrical equipment maintenance must be carried out by the electrician, not arbitrary action of others; work, pull down the switch in case of power failure cut off power supply, repair the end of the device must be carefully check the situation, not unusual, before closing. Maintenance of large electrical equipment should be cut off the power, after setting a good defense, and set up warning signs in the switching office, only after the completion of demolition, For transmission tests carried out must be carefully checked and contacted the authorities, before conduct. Large-scale bridge construction site, tunnels and prefabricated space should bring their own power, to avoid losses due to power outage and the emergence of the accident, between self-supply and power grid, have interlocking protection.
Pit road transport and water facilities, the venue should always maintain smooth. Truck traffic through more of roads, the bend radius is generally not less than 15m, exceptional circumstances may be less than 10m, the width of cart path is not less than 1.5m. Sharp bends and steep slope areas should set clear traffic signs, and railway intersections shall be hand care, and signaling devices, and drop shot set up. Office of rivers and steep roads, should be clearly warned that the village guard-rails and blog. Traveling inside bucket, flat cars flat track should be straight, grades shall not exceed 3%. Vehicle brakes should be installed, the railway terminal should be set down slope and car stalls. Water production should be identified, the water quality must meet the current standards. Water protection measures should be taken to prevent water pollution. Additional set up inside the wire should be absolutely fine, suspension height and line spacing must comply with safety requirements for electrical sector. On-site erection of the temporary line insulation support must not be entangled in the steel wires, trees or scaffolding. Near high voltage electrical operation, the safe distance: 10kv The following shall not be less than 0.7m, 20 ~ 35kv not less than 1m, 44kv not less than 1.2m, or to the rear blackout operational. All kinds of electrical equipment should be equipped with a special switch, outdoor switch, socket exterior waterproof box and locked, additional insulation in operating office cushion. In the three-phase four-wire system in
