BOCCA C250

BOCCA C250

Product catalog summary
Technical Specifications
The document describes a square-shaped grating made from ductile iron EN-GJS-500-7, compliant with EN 1563:2018 standards. It has a load-bearing capacity exceeding 250 KN (25 tons), aligning with the C250 load class as per EN 124:2015 standards.

Design and Features
The grating is a single cast unit, simplifying installation and reducing the load on the supporting wall. Its tall design allows for use in various pavements. The front features thin bars to facilitate water reception while preventing debris and rats from entering. The concave back with an inward slope aids in water channeling and flow. The walkable upper side includes anti-slip grips and a hole to ensure water drainage even if the street side is obstructed, preventing flooding.

Functionality and Benefits
This innovative pavement inlet addresses highway drainage issues, such as blockages from debris or reduced pavement rise due to asphalt embankments. It also allows easy access for maintenance workers to clear surface obstructions. The design is compatible with the CHC5070 rectangular manhole cover for pavement inspection.

Installation and Certification
The document specifies the installation location and confirms certification compliance, ensuring the product meets necessary standards for safety and performance.

BOCCA  C250-1

Lunghezza Larghezza Altezza Sup . deflusso Peso Length Width Height Flow suface Weight Griglia quadrata in ghisa sferoidale EN-GJS-500-7 conforme alla norma EN 1563:2018 con resistenza a rottura superiore 250KN (25 t) conforme alle classi di carico C250 prevista dalla norma EN 124:2015 Realizzata in monoblocco che ne facilita l’installazione e riduce il carico unitario sulla base muraria di appoggio. Lelevata altezza permette l’inserimento in qualsiasi tipo di marciapiede. Nell a parte anteriore presenta delle barre sottili che permettono un’ ottima ricezione delle acque ed evitano l’ingresso di eventuali rifiuti (sassi, foglie e lattine) e il passaggio dei ratti. La parte inferiore ha una forma concava, con inclinazione verso l’interno, che facilita la canalizzazione e lo scorrimento veloce delle acque La parte superiore, calpestabile, ha dei grip antiscivolo ed una foratura che assicura il defluire dell’acqua anche in caso di intasamento del lato stradale, evitando cosi eventuali allagamenti. Il nuovo modello di bocca da marciapiede risolve tutti i problemi di smaltimento delle acque meteoriche stradali tramite caditoie: ad esempio, quando la griglia verticale e intasata per la presenza di corpi estranei, foglie o altro, quando i riporti di asfalto tendono a ridurre l’alzata utile del marciapiede, o nel caso di alterazioni accidentali della sezione stradale. Il modello, del tutto inedito, agevola anche l’eventuale azione dell’operatore per liberare la bocchetta da intasamenti superficiali E predisposta per l’installazione con il chiusino rettangolare modello CHC5070 per l’ispezione del marciapiede. Square shaped grating in ductile iron EN-GJS-500-7 conforming to the norm EN 1563:2018, with load bearing capacity over 250 KN (25 tons) conforming with the load classes C250 as set out by norm EN 124:2015 TECHNICAL SHEET 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.
