Ground Surface Access Assemblies
A manhole cover 10 comprising a plurality of spaced, discrete, upstanding formations 22 arranged in a regular pattern over the majority of the visible surface 20. The formations have a height of 2-8mm and the majority are spaced from the neighbouring formations by a distance of 3-25mm. At least some...

description | A manhole cover 10 comprising a plurality of spaced, discrete, upstanding formations 22 arranged in a regular pattern over the majority of the visible surface 20. The formations have a height of 2-8mm and the majority are spaced from the neighbouring formations by a distance of 3-25mm. At least some of the formations are varied in terms of shape, size, or texture and are arranged in a regular pattern to form an image. The sets may define a second image that is only visible when the formations are altered by a predetermined amount of wear, where the second image indicated that the cover requires replacement. The cover goes to a ground surface access assembly 100 that comprises a base frame 16 and the cover. Blank formations 26 are modified in terms of shape, size, colour or texture. This can be achieved using a cutting tool. The cover may be cast using a mold and a rough casting, this casting may be machined using a computer numerically controlled (CNC) three-axis milling machine. |
