【正文】 為牽引力（N） ；R 為彎曲半徑（ m）Where: P for lateral pressure (N / m)。Therefore, pull the cable with plastic sheath. Each time the allowable length of 35KV cable is 428m and its lateral pressure is 4200N。每隔 20~30m 有一個人來注意電纜拉動情況；在每過路管前后應安排人員看護，同一過路管中第二根電纜開始穿管時，鋼絲繩與電纜連接處套上熱縮管；電纜轉角處有人看護，跟隨電纜頭行走人員通過對講機來指揮操作卷揚機工作人員。Cable bend radius should meet specifications, and pull cable in the trench should have appropriate snakelike bend. Leave appropriate laying surplus at ends, middle joints, threading, vertical potentiometer etc.2）電纜之間，電纜與其它管道、道路、建筑物等之間平行和交叉時的最小凈距，應滿足規(guī)范的要求。Three singlecore cables of the same loop should be bundled a triangle type with nylon belts with bundling spacing not more than . The center spacing of different circuits in the same cable trench is 20cm. 12 / 145）冬季敷設電纜，溫度達不到規(guī)范要求時，應將電纜提前加溫。Spread 10cm sand or soft soil above or below cable and cover with bricks or boards with width more than 5cm of both sides. 七. 回填土 Backfill Earth1) 直埋電纜回填土前，應經隱蔽工程驗收合格。標樁應牢固，標志應清晰，標樁露出地面以 15cm 為宜。Buried cable access to buildings and cable termination heads should hang signs.4) 電纜標志牌同時應遵循業(yè)主標準。The cable laying must meet the following requirements: Strictly prohibit twist, armored squash, sheath fracture and severe lacerations and other 13 / 14surface defects. Forbid parallel pipeline laying.檢驗方法：觀察檢查和檢查隱蔽工程記錄。②在電纜引入建筑物、與地下建筑物交叉及繞過地下建筑物處等受條件限制時，可淺埋，但應采取保護措施。When cables are laid in indoor trench, prevent casing for poor waterproof handling. Work in strict accordance with specifications and process requirements.5) 有麻皮保護層的電纜進入室內，防止不作剝麻刷油防腐處理。The buried cable construction should not be too early. Generally carry out after the pletion of outdoor works to prevent being damaged by other underground works. Step up inspection if pleted before other underground works.2) 直埋電纜敷設完后，應立即鋪砂、蓋板或磚及回填夯實，防止其它重物損傷電纜。 Self and mutual inspection records 2） 電纜工程分項質量檢驗評定記錄。在施工過程中要精力集中，服從指揮，聽從調遣，確保安全生產。All equipment should be inspected, accepted by owner and be labeled.4) 電纜溝開挖直到回填土完工，應盡可能地均衡、連續(xù)施工，縮短工期；在有行人的場所內施工，電纜溝開挖后應有警示牌及維護。Do technical and security clarification to the workers about security precautions and make a JHA..7) 總安全方案將遵循管理公司安全方案和業(yè)主的安全規(guī)定。 There should be warning signs and maintenance on pedestrian area.5) 現場禁止吸煙，班前班中嚴禁飲酒。不斷改善勞動條件，認真做好每個施工人員的勞動保護措施。Subproject acceptance records4） 電纜走向實測圖。Spread sands, cover boards or bricks and backfill after cable pulling to prevent being damaged by heavy objects. Draw pletion drawing timely and show the actual coordinates position and laying depth. 3) 電纜兩端頭處的門窗裝好，并加鎖，防止電纜丟失或損毀。Testing method: observe examination and check concealed works records and coordinate diagram.十一. 成品保護 Finished Protection1) 直埋電纜施工不宜過早，一般在其它室外工程基本完工后進行，防止其它地下工程施工時損傷電纜。Clean up debris, spread fine sand and soil sands, cover boards or bricks tightly and strengthen inspections on missing part. 4) 電纜進入室內電纜溝時，防止套管防水處理不好，溝內進水。Coordinate and elevation should be correct and arrange neatly. Set up sign stake and signboard accurately。The cable voltage test results, leakage current and insulation resistance must ply with the provisions of the construction specifications. 檢驗方法：檢查試驗記錄。The signs shall be the same size, have antiseptic properties, and mounted hanging shall be firmly.2) 標志牌上應注明電纜編號、規(guī)格、型號及電壓等級。The backfill should be timely layered and pacted. 八. 埋標樁 Burying Stake電纜在拐彎、接頭、交叉，進出建筑物等地段應設明顯的方位標樁。The cable laying should set mand contact system, contact with radio walkietalkie and handheld loudspeakers.六. 覆砂蓋磚 Spread Sand and Cover Bricks1) 電纜敷設完畢，應請建設單位、監(jiān)理及質量監(jiān)督部門作隱蔽工程驗收，作好記錄、簽字。Crossovering the existing cables to meet the regulatory requirements and maintain adequate spacing.4）同一回路的三根單芯電纜用尼龍扎帶品字型捆扎，捆扎間距不大于 。 Around each crossing pipe arrange workers to watch and sheathe heatshrinkable tube at the joint between the steel line and cable when the second cable threads in the same crossing tube. Watch the cable corner, and worker along the head part of cable uses interphone to mand the pulley operators.5） 每根電纜敷設好后，在電纜兩端做好臨時標示，以分清電纜回路及黃、綠、紅三相。電纜上不得有鎧裝壓扁、電纜絞擰、護層折裂等未消除的機械損傷。 R for the bend radius (m)水平直線牽引時：Horizontal straight line traction T=式中：μ 為摩擦系數，在滾輪上牽引時取 ~；Where: μ is friction coefficient, wheel traction is ~ W 為電纜每米重量（kg/m） ；L 為電纜長度（m ）W is cable per meter weight (kg / m)。 flat pulleys do not need fixing.電纜架與卷揚機布置見下圖： Cable rack and winch arrangement see below: 35KV：7 / 148 / 1410KV：9 / 14 電纜展放 Layoff Cable1) 電纜展放可用人力拉引或機械牽引。敷設電纜的機具應檢查并調試正常，電纜盤應有可靠的制動措施。如無箭頭時，可按電纜纏繞方向滾動，切不可反纏繞方向滾運，以免電纜松弛。Trench excavation and crossing cable tubes embedded have been pleted. Trench has no water and depth should meet the specifications. Spread bottom sand and be debrisfree.場地清理干凈、道路暢通。Other subsidiary material: cable marking piles, cable signs, paint, gasoline, sealed lead, stearic acid, white belt, rubber cloth
