【HaiChuan Safety Discussion】Several major groups come together for team-building activities

Pay attention to the location; avoid dangerous areas； Pay attention to the layout; don’t make it too crowded ； Pay attention to environmental protection and don’t litter; P

At first I didn’t see clearly and thought it was some kind of team-building activity; upon looking more closely, it turned out that the cable had been cut, and it was still just one cable

It turns out that the various sects didn’t keep any records of underground cables; now it’s embarrassing to dig them up

Besides the negligence of the construction team, are there any other factors that could lead to cables being cut?

It’s that serious? This on-site work is also very unsafe

It may also involve labeling of concealed works; inspections and supervision should be carried out if possible, and the owner certainly also has responsibilities

There were issues with the lack of rigor throughout various processes: for example, the cables buried underground were not documented in any diagrams; the diagrams did not indicate the correct locations for burying the cables; no warning strips were placed along the buried cables as required; no permits were obtained for carrying out these work; and no manual excavation was carried out

Generally, after losses occur, there are many issues that were not properly controlled, and it is the combination of these issues that leads to problems

The markers for directly buried lines should be placed accurately, buried properly, be complete and intact, have correct inscriptions, and clear writing; they must also comply with the following requirements: 1. Markers should be buried in locations that are unlikely to change over time. The straight-line marker is buried directly above the straight-run line, facing the direction of transmission; when the lines are laid along a road and are close to each other, it can face the road as well ； The marker stones at the joint are buried along the straight line, facing the joint ； The marker stone at the corner is buried at the intersection of the line corners, facing the inner angle ； The reserved marker stones are buried on the straight line at the reserved location, facing the reservation ； The underground obstacle marker is facing the starting end. 2. The numbering of marker stones is based on each relay section as an independent numbering unit. The numbering sequence runs from end A to end B, or as specified in the design documents/completion records. 3. At the joints where the insulation resistance of the metal sheath to ground is monitored, as well as the insulation resistance between the monitoring electrodes of directly buried splice boxes, monitoring markers should be used.
