Start of another culvert for road 2 on the Gaul Road March Site.
You would not believe the amount of soil being dug out, we are 3 metres deep against the road edge. By the way if you are carrying out this kind of work it would be wise to employ a structural engineer.
After the inspection of the dig he will issue a “permit to work”
First photo shows Alan excavating another 750mm below the slab level. This will make a total depth from road level to 3.750m.
Saturday 13th February 2016 shutter is being put up, at the same time the steel fixing can be completed.
3 vehicle accesses on to a new housing estate. Because vehicles have to cross a dyke there needs to have a culvert built, this is 2 head walls either side of the new access, built with concrete and reinforcement bars.
Day 1 after Highway approval, (as this is part of a S278) set up site as the norm
Day 2 As we are in a dyke, we have a water problem, best solution is when excavating, use the material to dam up the dyke. Pump the rest out.
Day 3 Road Entrance 1, Base of the first Head wall 6m x 3m (it is 2.4m below road level) knock some pegs in the soil base and concrete with lean mix, concrete about 50mm thick. This will be for the steel fixers to work on.
Day 4 Put together the steel bars, using plan and bar schedule. Fairly easy to read, example H16/02/39/3760 this is 16mm bar / 02 on plan / 39 bar / 3.760 lengths. Read with plan.
End of week 1
Day 5 After fixing steel, clean off the muck on concrete base in the dyke – lift into place – sit the steel on spacer 50 – 60mm
Day 6 complete steel fixing & get checked off by site manager & Highways
Day 7 Pour concrete
Day 8, 9, & 10 put together the steel for the other side & excavate base
Day 11 Monday 21st December 2015 Fix Concrete Pipe 600mm diamter inside steel bars & Shutter
