中建一局《施工现场临水临电标准化图册》

编制说明
为贯彻落实中建一局集团公司对项目临建标准化的要求，结合中建一局总承包公司的项目管理要求，总承包公司机电管理部、安全部对项目的临水、临电施工要求，特印发了试行版的《施工现场临水临电标准化图册》（以下简称《图册》）。《图册》的出台，将对总承包公司各新开项目临水临电施工加强了标准化管理，提高总承包公司新开项目施工现场临建设施、安全防护、CI形象的管理整体水平，发挥重要作用。《图册》中如与国家、地方有关规定不符的，以国家、地方有关规定为准。
《图册》中除带“☆”为建议做法外，其余均为要求做法。今后将会根据项目现场的优秀做法，定期进行更新。

（3）配电箱下部应对进出电缆线采取绝缘套管保护，并做相应标注区分进出线，操作面铺设绝缘踏板或胶垫，外侧配备消防器材。

4 配电线路 4.1 电缆埋地敷设 （1）埋深不小于 0.7 米，在电缆周围敷设不小于 5 厘米厚细沙，覆盖砖或硬质保护层，过路时穿保护管；易受破坏的场所选用铠装电缆。
（2）电缆引出地面时，从 2 米高至地下 20 厘米处，必须加设防护套管；套管内径不小于电缆外径的 1.5倍。
（3）埋地电缆的接头应设在地面上的接线盒内，接线盒应防雨、水浸入并远离易燃易爆、易腐蚀场所。
（4）在地面上，沿电缆走向路径设电缆警示标志牌，间距 15-20 米，转角处也必须设置。

4.2 电缆明敷设
基本要求：
（1）电缆沿地面明敷时应设置保护槽，保护槽应与地面固定，并设置明显警示标识。
（2）采用钢丝绳做吊索，将电缆用 PVC 管进行间隔固定，其间距为 0.5 米左右；吊索吊架间距不大于 12 米。
（3）电缆垂直敷设的位置应充分利用在建工程的竖井、垂直孔洞等，并应靠近负荷中心，固定点每层不得少于一点，水平向电缆线敷设应在墙体 2.5m 以上做支架架设，固定点应绝缘保护；

4.3 楼层配电
基本要求：
（1）电缆线穿越建筑物、构筑物、道路、易受机械损伤的场所及引出地面从2m高度至地下200mm处，应加设防护套管；
（2）电缆垂直敷设的位置应充分利用在建工程的竖井、垂直孔洞等，并应靠近负荷中心，固定点每层不得少于一点，水平向电缆线敷设应在墙体2.5m以上做支架架设，固定点应绝 缘保护；
（3）水平敷设宜采用三角支架或钢索进行高挂，高度不得低于2.5m，若因作业限制无法高挂的，可沿墙角、地面敷设，但应采取防机械损伤措施，并设警示标识；
（4）楼层内固定式配电箱应考虑做重复接地，接地体应预埋，重复接地竖向距离不大于20m（每5层）做一处。
（5）楼层配电箱位置设置应就近主电缆，原则不超过 3m。
