Carruthers might be able to identify their purpose.

I was a bit puzzled by these structures but they are described as 'blast walls' and were constructed as part of the post WW2 modernisation of RAF airfields.
They were sited on the airfield perimeter track where aircraft were dispersed and refuelled.
I assume that they were constructed in order to contain the blast should an armed and fully fuelled aircraft explode either by accident or design rather than to deflect jet efflux.
Such structures are angled so as to deflect jetblast upwards and wouldn't be as robust as these concrete walls.

ETA:

Just giving the subject a little more thought, the walls would also provide a degree of protection from attack.
