Concrete tubes in field by M25

[xjandy]

Anyone have any idea what the concrete tubes in the field next to the M25 between Caterham and Sevenoaks are for? Someone seems to be monitoring something.Been there for a couple of years now and often wondered what they are for.

Think they are methane vents.

Why do you say that? If they are the ones that are on the left going anticlockwise they probably are. The tubes are put round the pipe work so that it doesn't get damaged by blind tractor drivers.

Is there not a railway tunnel going through there?

Hi

They are drainage Vents, that feild used to have problems with drainage and runoff. No worries with tractors as they have sheep and cows in the feild no need to mow the grass.

I think the humour of saying Methane and Ar5e maybe to blame here

The field is on quite a slope and is only small.The concrete tubes are about 2 metres in diametre and about 1.5 m high and I have seen official looking people measuring something in the tubes on a few occasions.
I thought it might be the Eurostar tunnel but I thought it was much further round the M25.
Definately not drainage.
There was quite a bit of work done there about 4 years ago.
It is on the RHS going anticlockwise not far from the services between caterham and Sevenoaks.

Its bugging me now.

No where near the Eurostar line as it runs along the M20 up under Bluebell Hill to the M2 and runs along that to Ebbsfleet. The rings are standard drainage rings and they were put in as I think they had a drainage/subsidence problem. Could be to monitor future movement ?

It's for drainage, there was a landslide there a few years ago. Here's a rather hefty report into how it was sorted out:

I must spend too much time on the 25 cos I have noticed they have just put up Black 18" high newt fence in a field about 2 miles from there.
Dont you just hate newts and reptiles.Costing us a fortune!
