Trench Cut & Underground Vault Work

hot water pipe in between [Music] all right something else i want to show you guys you see this cut right here you see the ledge step up ledge step up that's how you make the cut so before the vault lid goes back on you put the weather stripping around the outside yeah it's a ram neck that's what it is so it's a butyl rubber what they'll do is they'll lay it down one or two layers on the ledges here and then they'll lift each piece of the lid in place so that it squishes down the butyl rubber to create a weather barrier so then once the lid is all set they'll use a butyl rod in between the joints of the lids and then they'll grout each joint all the way around and they'll uh weatherproof the roof and then once that's all done then they'll start backfilling what was the repair they had to do down here we had some valves in here that had been here since 1984 that were inoperable and so in order for us to be able to isolate different services and different legs of our loops yeah we got to isolate those valves so we removed them and replaced them with uh valves that are more current and up to date and then they're putting on a rg product that keeps the discharge piping from corroding and then they're insulating over the top of that
