  • In this video we investigate an underground tunnel. This tunnel is in the Irwell valley by the river Irwell. We are in Salford and not far from Manchester. We found this underground tunnel and decided to investigate. Clearly it has an industrial use as it has some old victorian pipework sticking out of it. We trace its source using old maps and Ordnance survey maps. We come to a junction in the tunnel where two other feeds join it. This is clearly something to do with the Outwood brickworks and the Manchester Bury Bolton canal. Possibly dug in the 18th century this is a man made industrial revolution piece of Industrial heritage

    In my old hometown there was a park with a manmade pond where people were allowed to swim in the summer. On the far side of the pond was an overflow drain that was hidden by reeds. It was 10' square and kept the pond from flooding the park during rain.
    The drain was a new addition to the park. There was the old part of the park where the original stream drained the pond; a decade ago they bricked off the edge of the pond and installed the overflow. Then the old part of the watercourse was basically forgotten.
    I went exploring down there one day and discovered that they had routed the overflow to the original watercourse. The culvert was huge, 9 or 10 feet high, and so naturally, I went in and explored. The tunnel went in about 50' and then had a 45 degree turn, went for another 20 feet, and you found yourself directly below the overflow drain.
    It's beautiful down there. A big chamber, probably 10' square and 12' high, with the sunlight coming down and a waterfall on each side. Once I was down there, I discovered that if one grubbed around a little, one could find bits of lost articles from swimmers that had washed in, including jewelry.
    There was another drain tunnel that left the chamber, and it was 4' high. So one day I brought some waders and tried to find out where it went.
    It was a concrete drain tunnel, and sloped gently down. I must have gone on for fifty yards, and it was a huge mistake...my knees and back were killing me the whole time!!
    The tunnel only emptied into a smelly runoff ditch full of stagnant water. I left both sore and disappointed.

    The pipe would have had a 90° bent down at the end and would be used as a steam release pipe. The idea here is that you can't release steam into a natural tunnel, since it too porous and would exit in random locations.
    Releasing it below the water line of a running river avoids the need to pump water from the river and a cooling system which condensates the steam.
    This is basically the easiest method to run a steam engine :)

      it seems to be a pipe built of steel or iron and made to take more pressure than a drainage pipe. the steam outlet theory seems plausible. would it be worth shining a focusing torch up it to see where it goes?

      @@vsvnrg3263 well it goes straight up below the tunnel, there's no doubt about that. But it's also clear that there's no way it goes past the junction and follows the stream further uphill, since the rock formation on the ground is clearly natural.
      So it's likely splitting where the junction is and heading to two steam machine locations.

    Fantastic Martin Zero production, with all the trappings ! Proper investigator mustaches, tea time twice and a pub finish. James is doing well, adding an adjacent land survey. The mystery deepens with hand scored tunnels with century's old construction survey on the cieling, a quality water source and what appears to be a substantial steam pipe from the early 1800's. A brick works, a canal works with Victorian engineering. It just cant get any better than this, Oh my :) Martin with James is on the job. If any one can get to the bottom of this, its Martin Zero !

    Heres another idea for you. I guess what you found there, are very old drainage tunnels, and were talking medieval times here. They probably wanted to turn a swampy area into farmland. When they saw the water disappear in the ground where you came out, they just widened and opened that natural cave so it can carry more water and drain the area. Its was also done, when they wanted to build big heavy buildings like churches, or castles, cause if there was too much groundwater, you couldnt dig a hole to the bedrock cause your hole would fill up with groundwater all time and these buildings need to be build on solid bedrock. So usually they would build drainage tunnels, or even create whole manmade rivers to drain an area and lower the groundwater levels, so the ground was dry and hard enough to build on and you could dig down to the bedrock without your working area filling with water all the time. Also, if your foundation is wet over long periods of time, that will erode and weaken even the hardest stone and in winter, the ice would crack your foundation to bits and could even blow rocks to pieces from the expanding that happens when water freezes. These architects back in medieval times werent stupid, they planned for their work to last hundrets of years.
    And last but not least, i think my point is proofen by the fact that theres a steampipe in the tunnel. The factory probably found a network of already existing tunnels and just threw their steampipes in there. Cause if you think about it, they had pipes, they could have just built a pipeline going straight downhill to the river, what would be the logic way to do it, shortest way etc. but it was probably a lot cheaper to just throw em in the tunnel where you dont need to built something new, instead of building foundations, fencing everything in cause of the hot pipe, buying building licences, buying the land you want to build your pipeline on... Instead you just put them in the tunnel and youre done.
    And the brickwall was probably to dam the water so the steampipe is submerged in water, cause as we in the tunneling business know, rock that heats up expands, so having a boiling hot pipe in the tunnel, would have made it collapse at some point. So they dammed the water so the pipe lays submerged in the cold water and gets cooled down.
    So thats my theory, could be 100% true or 100% wrong. And i just feel, if these tunnels were only 120 or 140 years old, they would have done it differently, like built an open waterway and bricked it up or something, not going to the very long and costly way of chisseling out a small tunnel by hand, just to get rid of some steam... Just doesnt sound right to me.

My guess (for what it's worth) is that the 'lost world' oasis where you emerged is the clay pit for the brickworks, that the brickworks started off as being for bricks to build the canal, and the tunnel was to drain the claypit without disturbing the bedrock where the canal was going to be built. So basically the tunnel came first, then claypit then canal.

      Seems unlikely to be honest, a canal company turning down a free source of water? It wouldn't have been dug by me with picks in the 20th century, so probably not the sewage works. I'm wondering if it was an outflow from the brickworks that the canal company didn't want polluting their canal maybe? There's no sign of the pipe at the other end of the tunnel, so that's probably under the sand one way or another at the junction (or possibly both sides). There's no way they'd go to all that trouble for nothing, that's a lot of work there.

    When you came out of the tunnel the banking you were facing was put there to prevent the river Irwell flooding onto the land behind, which was a natural flood plain.
    This banking would have prevented the natural drainage from the springs in the Nuttall wood so the tunnel you climbed through was constructed to enable the water to flow into the Irwell thus allowing the natural drainage from the land behind the banking.

    Everyone has a theory so here's mine...
    Agree with those who say it is redirection of natural watercourse under the canal - they had the need to do so and the workforce of tunnellers to do it. The side channels would be overflow drains from the pound (length of canal between locks) more or less directly above. Locks generally empty into the pound below thus conserving water.
    Now the pipe. Remember the brick wall at the entrance? If that were intact across the stream then there would be a decent head of water to power a water wheel or turbine of some kind - the pipe would have come up inside the tunnel somewhere but has since blocked. Alternatively it could have been used as a small water source to pump water INTO the canal when water therein was low. This seems a little odd seeing there is a bloody great river right there too, but issues with water rights etc could have played a part. Consider researching the canal plans if they still exist.

However, the sooner you guys stop being in denial about you going caving (that was so 'a caving trip') then you could wear waterproof overalls, wet socks in your wellies and thermal waterproof gloves - 'welly fails' will be a thing of the past! I know not all 'real cavers' wear all of that but I like to be warm whilst exploring! 🙂 Thanks for continuing to film your explorations for the rest of us to enjoy, it is very much appreciated!! 🤗

  • @Dave64track

    Brilliant video I was looking forward to you going back and having a look into this tunnel but didn't think it would be this soon. Quite a mystery this one obviously a river course that has been made bigger, but interesting why. It would be great if you could go back in time and see this pipe in action. I didn't expect you coming out the other end into a secret valley. I think that pipe was feeding some machine and behind the wall has just backfilled over time with rubble. The water would just go through the pipe and have a bit of pressure behind that wall but now it's just filled with gravel to the top of the wall. Great video intro loving the music great choice.

  • @BlackcloudRailways
    @BlackcloudRailways 3 ปีที่แล้ว +6

    Guesswork, but, there's the route of an old canal running along the valley. The side watercourse coming down from Nuttall Wood would need to be culverted under the man made waterway, the two side tunnels might be something to do with sluices from the canal or just additional surface drainage. There's also Red Rock Lane in the vicinity that might also explain the culvert.

    • @MartinZero
      @MartinZero  3 ปีที่แล้ว +2

      Yeah I did say that in the video Bob about the canal and the locks 👍🏻

    • @danieltoth-nagy5097
      @danieltoth-nagy5097 3 ปีที่แล้ว +4

      Yeah, Martin, the canal overflow does not need necessarily come from the lock, it can just come from there, above the watercourse, an optimal point to install it.
      You might have explored the brook's other tunnel above under the former railway, there should be one.

    • @nickcaunt1769
      @nickcaunt1769 3 ปีที่แล้ว

      From the OS Map contours the brook enters the tunnel at between 40 and 45m and emerges (having passed beneath the old canal) at 40m. The canal was built at about 42m.
      So the brook would interfere with the canal being at just about the same elevation. This gives both positive and a negative issues the engineer a solution.
      Positive: A good clean reliable spring fed water supply for free. James found a dried up water channel. Did this feed the canal?
      Negative: the brook could/would flood. Especially when the Irwell was in flood and backing up the brook. This had to be stopped. Perhaps the tunnel was cut to allow flood water to pass beneath the canal bed? Plenty of room for a flood pond in 'The land that time forgot'.
      The silted up side channels could be overflow weirs from the canal.

  • @pepedrat2982
    @pepedrat2982 3 ปีที่แล้ว +2

    I can tell you two things I've just found out.
    That stream and the tunnel are the boundary between Bolton and Bury (yay!)
    And before the brickworks spoiled everything Kilcoby Cottage served teas, and there was a campsite there.
    Plus the water from the stream from Nuttall Woods was so pure that the Agecroft Rowing Club, who used to row past formed the Agecroft Bathing Club.
    I don't know where they bathed, but I wonder if the pipework was related.
    Just a mad thought to put out there.

I noticed that the pick marks at the beginning of the tunnel and at the end of the tunnel were in a direction that showed the tunnel was dug from both ends to meet in the middle. (imagine how the swing of the pick will make the mark in a certain direction)
