Two for the price of one

Monday 19 August 

As we are all volunteers we have the flexibility to work around life's other commitments, so this week we have split attendance over 2 days. Monday saw Roger, Dave and Nigel back up at Stanton on Culvert 11A. Tuesday Stuart and Alastair went off down the far south of the line doing some preparation for upcoming structural examinations. 

First off, we go over almost live to our intrepid reporter Dave braving the storms at Stanton.

We start with Nigel delivering the first mortar mix of the day to Roger and heroically also managing to include in the barrow 3 blocks, (That's called productivity Ed.). The inside wall around the gabions was the focus of attention first thing.

Roger decided to go for two straight intersecting walls, rather than a curved wall, despite the brick cutting involved. To get a consistent cut on the bricks the cutting jig was brought into action, this involved a bit of studying the manual.

While the building was going on, Dave and Nigel set about covering the down side south wall with the small gabion stone, this is more for cosmetic reasons, to hide the concrete blocks. It's hard work as the stone has to be loaded and off loaded by hand, it's too big to shovel.

The weather was playing games, the stormy skies distracted us from time to time, although nearly all the rain thankfully seemed to pass to the south of us.

Next a by-pass pipe was inserted in the channel on the up side, weighed down with a sandbag and sealed at the sides and base by clay to allow the scour protection to be installed

A healthy flow established through the by-pass pipe, with almost no flow remaining in the brick channel itself.

Last jobs was doing the concreting, first the down side cess headwall footings top layer and then the up side scour protection. On the downside cess outlet we still has a flow of ground water to contend with, hopefully not enough to spoil the concrete.

Tuesday 20 August 

Culvert 45A is within the outskirts of Cheltenham, it has been a bit neglected up to now but a structural examination is looming. Clearing the way was called for.

The ash tree in the wing wall will come down before the examination, but the roots will not be removed. It may be a big job to sort out.

The culvert is on the end of a pipe that runs for about 500m from Pittville Lake, the tranistion point can be seen below

Next port of call was Southam Lane for a quick look at Bridge 42 before moving down to Culvert 42A to clear the headwall there.

The abutments on the bridge have a shaped section leading to the wing walls, the GWR built these using long angled bricks (double the length of a standard brick), Roger could have used these on Culvert 11A if we had any spares.

Culvert 42A is within the Racecourse grounds, this was a relatively simple job as it is on the annual clearance schedule.

Sometimes we wonder why we take so much kit out with us on jobs, today was an example as we loaded 2 brushcutters. Good job we did, as one had a catastrophic failure, the drive shaft clamp had cracked, it's not terminal, but it will be out of action for a while for repairs. 

Probable fatigue fracture

  3. What exciting lives you guys lead, discovering and exposing all these culverts and water channels! Who will want to work n this job - no trains passing here!
    The Ash tree illustrates why I have a fixation about self seeding Ashes and Sycamores appearing anywhere on or near my property are unceremoniously uprooted - forthwith! Trees in unwanted locations are an absolute menace if left to grow.

    It will be interesting to see how you get on with this job when you get going.
