From the Boat House to the River

Very little has changed in this area except that many of the logs, a result of the bank clearance, have been washed into the stream by the floods.

The work at the Fiveways or Kings Acre site continues in earnest.

The digging of the new culvert from Fiveways to Broadmeadows is continuing.

The railway embankment has been dug away, as can be seen in the photo below. The remains of it can just be seen on the right of the shot.

The new line of the channel has been cut through where the entrance to the area used to be. The new tunnel under the road is yet to be added.

The previous tunnel under this area looked to be around 24" (600mm) in diameter (and it may have been blocked with silt) so this should be a large improvement on the drainage in this area. The previous channel can be seen in the photos on the 25th November 2007.

Here the concrete has been poured into the shuttering to form the bottom of the tunnel.

Just after this the whole area was flooded. Fortunately the concrete will still cure even though it is under water (provided the cement is not washed out).

The Bifurcation Tunnel and Falling Shaft area

Here the steel reinforcing is being finalised ready for the concrete to be poured to form the base of the tunnel. In the left-hand picture the edge of the falling shaft can be seen.

The Falling Shaft area

Here the bottom of the pit where the Bifurcation tunnel will be, is a hive of activity as preparations to build the tunnel progress.

The shuttering around the sides of the pit can be clearly seen along with the support framework to prevent the shuttering ans sides of the pit collapsing in.

The Falling Shaft

These two shots were taken from the bifurcation tunnel which is the area where the Chatterly Brook culvert will split and will feed either into the falling shaft (and into the new deep culvert) or into the exisiting culvert depending on the volume of water. The left shot shows what will be the link to the exisiting culvert that runs from Fiveways to behind the swimming pool and the right hand shot shows the original Chatterly Brook culvert after the excavations at that time.

The Chatterley Brook1 is normally nothing but a small trickle of water unless the Rudhall Brook is overwhelmed and floods. At this point the water flows into the Chatterley Brook1 and down to the Fiveways area. As a result, under normal conditions the water will follow the Rudhall Brook. In a potential flood situation when the Rudhall will overflow into the dunded area on the east of the A40 and this will, in tern, feed into the Chatterly Brook and flow either down the exisiting culvert or new culvert to the Rope Walk area depending on the sheer quantity of water.

Homs Road and Rope Walk area

The problem with the Rope Walk area is that it regularly floods whenever the Wye bursts its banks. This meant that it was impossible to see if anything had changed during the past week.

Broadmeadows

The stream has been dammed up on either side of the causeway and the water is pumped around from the upstream to the downstream side whilst work is in progress. A deep trench has been dug part of the way across the gateway (in the middle of the picture). Presumably this will form a new culvert under the road.

There arevery few visible changes here. On the FAS notice board, at Fiveways, it is reported that the vertical shaft here is nearing completion and that the tunnel boring machine will arrive early in the new year.

The Fiveways works were a hive of activity this morning. It appeared that there was a problem with a pump and the shaft was filling with water. This was a problem as there was a mini-digger in the hole and work could not continue until it was drained.

The photos here show that the steel mentioned in the last update has been used as shuttering to prevent the shaft from collapsing in. Also it is possible to see that the red frame is also part of the shuttering as it is providing the internal support. Persumably this shaft is needed to allow access to the culvert further across the carpark site.

Broadmeadow

This area is now fenced off a fairly long distance from the works so access is not possible and the distance means that photos are also not possible.

The Railway Embankment

Here we see the railway embankment being excavated, from several angles, by the Caterpillar (CAT) excavator. Quite a large section has been removed. Once the works are complete then it is a requirement that the excavated area of the embankment, which is council property, be rebuilt but it will be at the same level as the upper car park (previously it was several feet higher).

The Railway Embankment

Here we see the Caterpillar excavator loading a lorry. The bucket on the excavator looks huge which is a perspective effect. In actual fact, due to the size of the excavator, it only took three or four bucket loads to get close to filling the lorry.

Update on the Homs Road area
(Click for a larger image)

This week there are a few mysteries and this is the fist one. I am not sure what this piece of steelwork is for. Maybe it is going to be part of the tunnel lining or is part of some tunnelling machinery?

The area behind the boat house is being cleared of trees and bushes as the focus of the channel works moves further down the towards the river.

In the photo to the right, the bank can be clearly seen as having been built up with bags of concrete to prevent the bank being washed out from under the boat house.


Fiveways

The new culvert has now had all the water pumped out and this is being maintained using an electric pump running off a generator.

The frame in the photo below is currently another mystery. A depression has been dug and a frame (the red bars) have been assembled here. Quite what this is, is unclear, it maybe part of a larger structure yet to be built. It is built around the digger so it has to be moved in order to get the digger out of the hollow.

In the photo below-left, some formed steelwork can be seen. Presumably this is to hold up a bank or some form of reinforcement.

In the photo below-right, the work on the old railway embankment continues.

(Click for a larger image)

This is the existing tunnel at Broadmeadows. The channel is very narrow at this point and it is a major restriction to the flow. This area must have acted as quite an effective dam in the past thus restricting the flow and possibly helping to reduce the flooding further downstream from the Chatterly Brook at least.


The Bund

The work continues in the bund area. To the far right in the photo below can be seen a wheel washing machine to prevent mud being carried from the site onto the A40.

In the photo below to the left-bottom corner can be seen one of the waterways that feeds down through Broadmeadow and on to Fiveways. The Rudhall Brook follows the line of the hedge running approximately from the left-middle to the top-centre of the picture.

These heaps of soil have appeared over the last few weeks and are probably the spoil from the excavations further down the channels from Broadmeadow to Fiveways.

In the Homs Road area, excavations of the new channel for the brook are continuing. Also the new shaft is still being dug out and is now being constantly pumped out.


The Bund

Further excavations at the bund have been carried out to build up the bank for the bund. This is a temporary bund that is being built to allow the work downstream to continue throughout the winter. After this, the final bund will be built in this area. Everyday GPS position measuring equipment is used to check that the alignment of the banks exactly match the plan.

To the east of the A40 bypass, a bund is being built. Here the water will be dammed up to help prevent the bottom of town from flooding. The water will then be released at a controlled rate so that the water courses can cope with the addition.

Brookend Sluice

The area around the sluice has been cleared of bushes and trees. This is the area pretty much before the works start. The end of the original culvert from Kings Acre that goes towards Homs Road can be clearly seen.

The single remaining sluice guide can be seen beside the remains of the mill pond wall.

In preparation for the Flood Alleviation work starting, core samples have been taken in Kings Acre car park and in the Home Road car park in order to determine the underlying geology of the area. This will help to give a more detailed indication of the ground conditions and rock types under the surface and thus give an early indication of the kind of problems that could occur.

1 The brook referred to as the Chatterley Brook is actually a unnamed brook that flows from Weston-under-Penyard past Chackley Grove. It has only recently become referred to as the Chatterley Brook and locally it was previously known as Chackley Brook.
