9、前向作业人员进行施工交底 Construction orientation to workers2）在开挖前向施工部门提出申请 , 对施工内容作出风险评价 , 采取防范措施 , 报 HSE部门批准 . PTW approved for excavation and risk analysis assessed andapproved by HSE.3）画线 首先根据根据施工图纸确定电缆沟地走向, 然后根据沟内电缆根数、电缆间地距离确定电缆沟地宽度Line out the trench and determine the width oftrenchbasedofthequantityofcab

10、lesandtheintervaldistancebetween cables.4）挖沟 根据图纸要求确定电缆沟地挖掘深度（如图所示）, 当路面不成型时 , 应考虑规划路面地标高 , 以保证路面修好后电缆地深度能满足规程地规定, 与管线交叉时 , 应根据实际条件加深电缆沟或加保护设施. Excavation depth shall followthe DWG. In case the road not yet formed, the excavationdepth shallalso considerthe finalroadelevationand thedepthshall meet th
