Clear debris in advance and backfill uniformly on both sides and pact4） 夜間施工時(shí)，應(yīng)合理安排施工項(xiàng)目，防止挖方超挖超深。電纜敷設(shè)完畢，應(yīng)抓緊回填工作。Build site roads and appropriate work area. Widen and strengthen order to facilitate safe 9 / 11construction.2） 電纜溝開(kāi)挖工程應(yīng)注意邊坡和基坑的穩(wěn)定性，一般應(yīng)按先深后淺的順序施工，并應(yīng)采取必要的保護(hù)措施。Cable engineering subitem quality inspection and evaluation records3） 分項(xiàng)工程驗(yàn)收記錄。Note subsidence and deformation of neighboring existing buildings or structures, roads, pipelines etc. Take protective measures with design and construction unit and construct observation on settlement or displacement. 3) 在敷設(shè)有地上或地下管線、電纜的地段進(jìn)行土方施工時(shí)，應(yīng)事先取得有關(guān)管理部門(mén)的書(shū)面同意，施工中應(yīng)采取措施，以防止損壞管線，造成嚴(yán)重事故 Conduct earthwork on the area needs to lay ground or underground pipelines, cables prior to getting written consent of the relevant administrative departments. On construction take measures to prevent damaging pipelines and cause serious accidents.八. 施工記錄 Construction of Record1) 自互檢記錄。Do not collide targeting criteria piles, axis cited pile, and standard level points, etc. on moving earth. Regularly measure and check whether the plane location, elevation and slope gradient are in pliance with design requirements. Remeasure and inspect targeting criteria piles and standard level points.2) 土方開(kāi)挖時(shí)，應(yīng)防止鄰近已有建筑物或構(gòu)筑物、道路、管線等發(fā)生下沉和變形。并應(yīng)經(jīng)常測(cè)量和校核其平面位置、水平標(biāo)高和邊坡坡度是否符合設(shè)計(jì)要求。The excavation size is not enough: Cable trench bottom width should be increased as per construction needs.6）電纜溝邊坡不直不平、基底不平：應(yīng)加強(qiáng)檢查，隨挖隨修，并要認(rèn)真驗(yàn)收。The construction sequence is unreasonable: earth excavation should begin from the lower place, layer by layer and section by section in turn。 Invite related personnel to check the excavated trench and carry out the next working procedure after passing the examination.六. 質(zhì)量控制 Quality Control 電纜溝外形尺寸允許偏差表 Allowable deviated external dimensions of cable trench table允許偏差項(xiàng)目 allowable deviationitem 電纜溝外形尺寸允許偏差 allowable deviated external dimensions of cable trench table序號(hào)s/no項(xiàng)目 items 允許偏差（mm）allowable deviation檢驗(yàn)方法 test method1 標(biāo)高 elevation ＋0mm ，－50mm 用水準(zhǔn)儀檢查 water level check2 長(zhǎng)度、寬度 －0 mm 由設(shè)計(jì)中心向兩邊量、拉線和尺量檢查 design 8 / 11length, width center measure and pull line on both sides and ruler inspection3 邊坡偏陡steep side slope不允許 not allowed 坡度尺檢查 gradient ruler inspection 應(yīng)注意的質(zhì)量問(wèn)題 Quality issues1） 溝底超挖：開(kāi)挖電纜溝不得超過(guò)溝底標(biāo)高，如個(gè)別地方超挖時(shí)，其處理方法應(yīng)取得設(shè)計(jì)單位的同意。Earth excavation should not be done in the winter period. If necessary, take winter program.采用防止凍結(jié)法開(kāi)挖土方時(shí)，可在凍結(jié)前用保溫材料覆蓋或?qū)⒈韺油练宜?，其翻耕深度?yīng)根據(jù)當(dāng)?shù)貧夂驐l件確定，一般不小于 0．3m 。On pluvial days excavate pit (groove), pay attention to slope stability. If necessary, low slope or set up support. Meanwhile enclose embankment around the pit (groove) or did a ditch to prevent surface water inflow. Strengthen on checking the slope, support, embankment etc.8）土方開(kāi)挖不宜在冬期施工。同時(shí)應(yīng)在坑（槽）外側(cè)圍以土堤或開(kāi)挖水溝，防止地面水流入。Arrange personnel on manual excavation line rather than taking mechanical excavation. Pay attention to underground pipelines.7）土方開(kāi)挖一般不宜在雨季進(jìn)行，否則工作面不宜過(guò)大，應(yīng)分段逐片的分期完成。When C581 South Line temp
