Damaged Primary Cable

This primary cable (pictured below the secondary) was as some people believe, damaged before the water at high pressure damaged it further, but regardless if it was damaged or not it should’nt have been hit with how every many psi did hit, which was probably more than the suggested 1500 psi when working around buried power cables.

It was in a common ditch, which in this day and age is a common practice in newer subdivisions and developments, where primary power and secondary cables as well telecommunication utilities are buried together in a ditch. Gas-line’s are usually buried a meter away from everything else.

The person(s) that were hydrovacing at the time got away their lives and with only minor injuries to one of the parties. It could have been much worse, causing death to both of them.

Secondary Cable That Has Been Damaged By High Pressure Water

This cable could have been damaged before the high pressure water hit it but who’s to say, but in all likelihood it was’nt.

It is recommenced that when working around primary and secondary electric cables that your pressure is at 1500 PSI and your water temperature is at 70 degrees. Any higher pressure and hotter temperatures will rip open the outer coating of both in a matter of seconds.

Wax and Tinfoil Don’t Like Water

Wax and Tinfoil Don't Like Water

I never actually have seen the gas pipeline that is coated with wax and tinfoil and that has been buried for 59 years and nor do I want to since it is a very delicate job to expose the pipeline with out having the water from the oscillating tip rip into the coating.

Now if you want to bury anything near the gas pipeline you have to do it beneath it and at least three feet.

It’s a horizontal hydrovac to complete the job so that the other utility can be buried and this was in some really hard clay north of Grande Prairie, Alberta and at a depth of 3 meters.

One Nightmare of Hydrovacers

The photo shows if you look closely at the left boot a cut across the boot. This happened because the hydrovacer was working alone while the other person sat in the truck because they forgot their hard hat and did’nt have a spare on board. If not careful the hydrovacer could have cut into their foot since the person was using a straight tip not a oscillating tip. Thankfully the person was ok but boots of this kind cost upward of $250.00 dollars to replace.

Non-Typical Road

Non-Typical Road

Stressed out would have been an understatement when I got the hydrovac truck pulled in backwards and the pushed out on this non-typical road to a lease. My own fault when all was said done since I should have made sure that I had at least one pull hook for the truck on the truck, but as it turned out I did’nt have any. Chaining up in my opinion would’nt have helped since this area had recently had got hammered by rain and there was standing water everywhere not draining off.

The pipeline was on the left hand side of the road. The wooden stake shows it’s location.

At the end of the job the consultant decided that  they were going to mat the road to complete the job.
