UK Aston Gas Works- Birmingham- March 14

Recommended Posts

Originally, gas was only used for lighting for a few hours at the start and end of each day. Storing gas was the solution to make it over a longer period. The first gas holders were a “bell†floating in a tank of water. Calibration marks were used to show on the floating bell showed how much gas was being made or used. Later in the 19th century, gas holders became larger and telescopic sections were added. Waterless designs were introduced from Europe in the 20th century. Many gas holders remain in use today in Britain, being filled at night and emptied during the day in the winter. First gas pipes were generally made of iron, they are now made from polyethylene for higher pressures.

There are two basic types of gasholder  rigid waterless and telescoping. Rigid waterless gas holders were a very early design which showed no sign of expansion or contraction. There are modern versions of the waterless gas holder, e.g. oil-sealed, grease-sealed and "dry seal" (membrane) types.

Telescoping holders fall into two subcategories. The earlier of the telescoping variety were column guided variations and were built in Victorian times. To guide the telescoping walls, or "lifts", they have an external fixed frame, visible at a fixed height at all times. Spiral guided gasholders were built in the UK up until 1983. These have no frame and each lift is guided by the one below, rotating as it goes up as dictated by helical runners.

Both telescoping types use the manometric property of water to provide a seal. The whole tank floats in a circular or annular water reservoir, held up by the roughly constant pressure of a varying volume of gas, the pressure determined by the weight of the structure, and the water providing the seal for the gas within the moving walls. Besides storing the gas, the tank's design serves to establish the pressure of the gas system. With telescoping (multiple lift) tanks, the innermost tank has a ~1 ft wide by 2 ft high lip around the outside of the bottom edge, called a cup, which picks up water as it rises above the reservoir water level. This immediately engages a downward lip on the inner rim of the next outer lift, called a grip, and as this grip sinks into the cup, it preserves the water seal as the inner tank continues to rise until the grip grounds on the cup, whereupon further injection of gas will start to raise that lift as well. Holders were built with as many as four or more lifts.

      Back in July, myself and @mookster revisited a site which we both explored back in May 2010 where we piloted my beloved 1978 Land Rover Series III to leafy Surrey.  It was a roasting hot day and as an explorer of a year and a bit, it was an exciting huge factory explore which we spent hours in.
       
      Fast forward well over eight years and we decide to try a few sites around Surrey and London and head here for a revisit.  A lot had happened here in eight years; all documented on crappy YouTube videos and various visits over the year, the site had been torn apart, once secured with guards, fences erected and just pillaged for its innards.  
       
      I'd heard about being a muddy swamp inside in the rain; hardly suprising as it was a cat litter factory producing cat litter mined from Fullers Earth from a quarry on the same site.  
      We arrived on site in a similarly ancient car; my 1988 Volvo 240 GLT on a much hotter day; quite a roasting day.  Perfect exploring weather.
       
      The years had not been good; it was battered, beaten and stripped beyond recognition; not suprising seeing as it shut in 1994. I did not recognise this place at all.  But it kind of had a charm in the summer sun, it looked like the sort of factory you'd explore on GTA Free Roam, or Driver and find Tommy Vermicelli hiding!!
       
      Good to see it again for nostalgia in any case.  
       
      We spent an hour ish here before moving on to London where we ended up sitting in traffic for ages and going to a very tasty place which served bowls of meat gravy with a burger to bathe in it.  Very good it was too!

      Found our way into a small cave in the Yorkshire dales.

      Along the road in the Yorkshire dales we came across many small caves.
      We ventured into some of them, and saw some cool things.
      Next year we plan on returning and Exploring the larger caves.

      As part of another backlog of our West Country Trip, @Mookster, our American Explorer Friend @cgrizzy and myself traveled to this rather derpy site.  It's one of the list but little of interest remains inside; though its quite large, with long concrete voids with some pretty good Graffiti in places.  
      Not much was going on inside; except some kids with a makeshift skate park in the middle who seemed slightly suprised to spot us.   There is some really cool shots of nature reclaiming in here; lots growing everywhere and areas have collapsed.
       
      The Dries in Wenford were built in the early part of the 20th century (likely post-1907) to serve the local china clay pit at Stannon on Bodmin Moor.  
      China Clay in liquid form was carried in a pipeline from the pit to the settling tanks behind the dries. 
       
      The dries operated until the final closure in 2002 (aside from a brief closure during WWII). The works were originally built by the Stannon China Clay Company, but were acquired by English China Clays in 1919. The choice of site was heavily influenced by the presence of an existing railway line leading from Wenford Bridge which was originally constructed to carry granite from the nearby De Lank quarries. The dry was built adjacent to the railway line and a large private siding was built to connect to the network.

      History
      Maes Mynan care home was a two floor 33 bedroom care home on a site of 2.6 acres.
      The care home was for the elderly and it had its own day service and its own respite service for a short stay and emergency placements.
      The site was bought in 2013 by the healthcare company and has been left untouched since.
      The building itself we could not find much history about or anything about when the care home opened.
       
      Our Visit
      We decided to visit this place when we went out on a day trip to Engedi chapel (report will be up soon).
      On the way back we still had a lot of daylight left so we thought we would stop in and have a look at this site after seeing a report.
      The surrounding area was very overgrown and there was a long pathway leading up to the build.
      The site itself was in pretty good condition, well worth the visit if you have any free time.
      Be mindful if you do visit as just at the back of the site, there is a house that we assumed is occupied.
