Here is the beginning of a pipe burst job on a shared 6" side sewer. This is just the excavation stage more to follow tomorrow. The shared line ran real close to the fence, the problem was the homeowner wanted the trees saved at all costs. We used an excavator in the backyard because instead of 1 small pit (2x3) we needed to tie in the neighbor as well so we made a traditional hole to expose both connections. This is the shallow hole as it is at 7 foot. But we would have loved to do a pull on this with the Tric Pipe burster but in the front yard there was another tie in so we used the vacuum excavator to make two 7' 5" holes one to tie in the other line and one to do the actual pull with the burster. The holes came out ok pretty clean and 3 x4 and 3x3. Notice in one picture the abs pipe on a shovel to get the depth we needed to break up the soil so it could be sucked out. We did not use the pressure washer for the most part because that makes slurry and has to be dumped in a special location over 20 miles away. So we did it dry so we could re use the soil for the backfill. Anyway here are some pics Part 2 tomorrow of the bursting. So this is 2 neat technologies being used, Vacuum excavation and pipe bursting. Edited also notice on the shovel picture the pipe we found that wasn't located by the utility companies I still don't know what it does but the vacuum didn't hurt it when we found it.
No announcement yet.
