It is made as a single cast, which facilitates its installation and reduces the unit load on the supporting wall. It is particularly tall, which means it can be used in any type of pavement. It presents thin bars on the front, which allow the reception of water and avoid the introduction of any rubbish (stones, leaves and cans) and the intrusion of rats. The back side is concave in shape, with a slope towards the inside, which facilitates the channelling and the efficient flowing of water. The upper side, which can be walked on, presents anti-skip grips and a hole, which guarantees the flowing of water, even in case of obstruction on the street side, thereby avoiding any eventual flooding. The new pavement inlet solves all the problems of highway drainage thanks to drains gratings: for example, when the vertical grating is blocked due to the presence of rubbish, leaves or other, when the asphalt embankment tends to reduce the rise of the pavement, or in case of accidental alterations of the road section. This model, totally new, facilitates any action of workmen to free the inlet from surface obstructions. It is conceived for installation with the rectangular manhole cover CHC5070 for pavement inspection. STANDARD EN 124 CLASSIFICATIONS AND PLACES OF EMPLOYMENT Manhole covers, gullies and gratings can be distinguished into the following classes: A15, B125, C250, D400, E600 ed F900. Group 3 (Class C250 minimum) For gullies installed in kerbside channels of the pavement which, extends to 0.5 m in the road and to 0.2 m top on the pavement, when measured from the edge.
