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。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(shè)完后，應(yīng)立即鋪砂、蓋板或磚及回填夯實(shí)，防止其它重物損傷電纜。Testing method: observe examination and check concealed works records and coordinate diagram.十一. 成品保護(hù) 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(jìn)行，防止其它地下工程施工時(shí)損傷電纜。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(hù)層的電纜進(jìn)入室內(nèi)，防止不作剝麻刷油防腐處理。Clean up debris, spread fine sand and soil sands, cover boards or bricks tightly and strengthen inspections on missing part. 4) 電纜進(jìn)入室內(nèi)電纜溝時(shí)，防止套管防水處理不好，溝內(nèi)進(jìn)水。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(shí)，可淺埋，但應(yīng)采取保護(hù)措施。Coordinate and elevation should be correct and arrange neatly. Set up sign stake and signboard accurately。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(yàn)方法：觀察檢查和檢查隱蔽工程記錄。The cable voltage test results, leakage current and insulation resistance must ply with the provisions of the construction specifications. 檢驗(yàn)方法：檢查試驗(yàn)記錄。Buried cable access to buildings and cable termination heads should hang signs.4) 電纜標(biāo)志牌同時(shí)應(yīng)遵循業(yè)主標(biāo)準(zhǔn)。The signs shall be the same size, have antiseptic properties, and mounted hanging shall be firmly.2) 標(biāo)志牌上應(yīng)注明電纜編號(hào)、規(guī)格、型號(hào)及電壓等級(jí)。標(biāo)樁應(yīng)牢固，標(biāo)志應(yīng)清晰，標(biāo)樁露出地面以 15cm 為宜。The backfill should be timely layered and pacted. 八. 埋標(biāo)樁 Burying Stake電纜在拐彎、接頭、交叉，進(jìn)出建筑物等地段應(yīng)設(shè)明顯的方位標(biāo)樁。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(yīng)經(jīng)隱蔽工程驗(yàn)收合格。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(shè)完畢，應(yīng)請建設(shè)單位、監(jiān)理及質(zhì)量監(jiān)督部門作隱蔽工程驗(yàn)收，作好記錄、簽字。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(shè)電纜，溫度達(dá)不到規(guī)范要求時(shí)，應(yīng)將電纜提前加溫。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?jiān)鷰纷中屠υ?，捆扎間距不大于 。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(shí)的最小凈距，應(yīng)滿足規(guī)范的要求。 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(shè)好后，在電纜兩端做好臨時(shí)標(biāo)示，以分清電纜回路及黃、綠、紅三相。每隔 20~30m 有一個(gè)人來注意電纜拉動(dòng)情況；在每過路管前后應(yīng)安排人員看護(hù)，同一過路管中第二根電纜開始穿管時(shí)，鋼絲繩與電纜連接處套上熱縮管；電纜轉(zhuǎn)角處有人看護(hù)，跟隨電纜頭行走人員通過對(duì)講機(jī)來指揮操作卷揚(yáng)機(jī)工作人員。電纜上不得有鎧裝壓扁、電纜絞擰、護(hù)層折裂等未消除的機(jī)械損傷。Therefore, pull the cable with plastic sheath. Each time the allowable length of 35KV cable is 428m and its lateral pressure is 4200N。 R for the bend radius (m)水平直線牽引時(shí)：Horizontal straight line traction T=式中：μ 為摩擦系數(shù)，在滾輪上牽引時(shí)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)。 Use manual or mechanical traction.
