Measures of security equipment external wiring work on water supply and sanitation
Outdoor plants for water and sewer are generally buried shoots.
This placement requires the execution of grooves, whose depth and width that depends on pipe diameter, the freezing of the ground, the slope of the pipe junctions with other pipes.
Prior to execution of several trenches grooves run perpendicular to the trench direction, to identify any existing or cables run.
Excavations to start work only if the driver is aware of these pipes and if he obtained permission to dig at people in the law.
If after beginning to discover other facilities underground excavations previously unknown works to stop their identification and determination of how to avoid dangers that might arise in case of further works.
Excavation permits for land consolidation are filling up at a depth of 0.75 m to 1.25 m to the middle ground and hard ground with the pickaxe and spade dug up to 2m.
For depths greater support should be run with planks and beams, so that digging and assembly operations can continue without risk of subsidence of trench walls.
If the ditch is a ditch run parallel with the old, closed, helping run the banks, whatever its depth, because the earth is our uniform Tamping partial collapses can occur, leading to breaking the existing pipe.
Earth excavation to throw results in one side of the trench, at a minimum distance 0.7m.Pe other side of the trench is deposited all pipes and mounting materials distance of 0.7 m from the edge, not rolled in ditch , wounding or killing workers.
Lowering pipe in the trench is performed by Tripod and cable release.
Their disposal is not allowed in the trench and no temporary location on the rails during descent reinforcing.In pipes is forbidden to be stationed along the trench workers, even if that portion does not affect the launch..
Joining the pipe works in the trench will be intotdeaua by groups 2 to 4 workers at each site.
The pipe in the trench work in one or two workers properly equipped with goggles, boots and protective clothing.
It is recommended that they be tied with safety belts.
Belt cord is removed from a ditch, a player who oversees the operations of assembling and others may occurs with the appearance of any emanations or injury.
