COVER, DRAIN AND GRATING FOR ROAD AND OTHER USES, VERTICALLY ADJUSTABLE BY 150 mm AND OVER, TILTING AROUND 360 degree WITH AN ANGLE OF INCLINATION OF +/- 10 degree AND FITTED WITH A SELF-LOCKING RING FOR FIXING THE COVER TO THE ROAD SURFACE WHEN ADJUSTMENT IS COMPLETE

摘要

The subject of the invention is a drain cover of a new generation, conceived in such a way that its height and inclination can be adjusted easily to correspond exactly with the form of the road surface. In particular, the adjustment possibility can be exploited both when laying for the first time and when the road is subsequently resurfaced without the need for demolition and reconstruction work.
