| 説明 | On Hankley Common in Surrey is a formidable array of Second World War anti-tank obstacles, representative of those found along the Atlantic Wall on the western coast of mainland Europe. If the Allied forces were to mount a successful attack to re-take Europe they would have to possess the knowledge, skills and equipment to break through some of the toughest reinforced concrete defences ever constructed.They were reportedly constructed by Canadian soldiers (possibly from the Royal Canadian Engineers) as a testing ground for a series of conventional and innovative weapons.The most prominent of the obstacles is the 100m long reinforced concrete wall that is 3.5m wide at the base and almost the same height. It has been constructed in two sections; east and west, with a 5.3m section in the middle for a vast steel gate (since removed). There are dozen of craters along the front of the wall (the north face) and two complete breaches, one on each section measuring around 4m wide.Fifty meters to the rear (south) of the main wall is a secondary wall. Standing under 2m in height, it is 1.8m thick and appears to consist of much shorter sections. Without cutting back undergrowth I was not able to ascertain if this rear obstacle was one continuous wall at any stage or has always been sectional. To the west of both walls is an area with a selection of smaller concrete anti-tank obstacles; A row of four concrete pyramids, a cluster of three rows of seven pyramids, and four rows of 7+2 concrete blocks. There is also a single remaining large concrete block, measuring 120cm x 120cm square by 150cm in height.Another feature remaining on this curious site is a steel cage of reinforcing steel that doesn't appear to ever have had concrete cast over it. The most interesting aspect of this is that the reinforcing steel has been welded into a three-dimensional framework; this is likely to have been considerably stronger than the British method of using steel wire to tie reinforcing steel together. Perhaps this was done using evidence obtained of the German construction methods. |
