Precast concrete products - Box culverts

This standard deals with both large (structural) and small (non-structural or light structural) box culverts of rectangular cross-section formed monolithically and designed as continuous elements with a joint detail shaped to allow the possible incorporation of sealing materials. Box culverts can be used for creation of voids below ground for conveyance and storage of materials. e.g. conveyance and storage of wastewater, cable tunnels and subways
For the purposes of this standard, box culverts having internal cross-sectional dimensions (W and H in Figure 1) less than or equal to 1 250 mm should be considered as small (non-structural or light structural). All other units should be defined as large. The elements are generally manufactured in factories using either normal weight or lightweight concrete and usually require reinforcing steel. This standard does not include units manufactured from autoclaved aerated concrete, nor prefabricated reinforced box culverts of lightweight concrete with open structure.
Each unit is structurally complete. They are used in combination to form a total structure of appropriate length (including joints) and capacity.

Betonfertigteile - Hohlkastenelemente

Diese Europäische Norm behandelt sowohl große (tragende) als auch kleine (nicht tragende oder eine geringe Tragfähigkeit aufweisende) Hohlkastenelemente mit rechteckigem Querschnitt, die monolithisch hergestellt werden und als aneinander gereihte Elemente mit einer Fugenausbildung entworfen sind, wobei die Fuge so geformt ist, dass Dichtstoffe eingebracht werden können. Hohlkastenelemente können dazu verwendet werden, unterirdische Hohlräume zu schaffen, die für den Transport oder die Lagerung von Materialien, z.B. für den Transport und Lagerung von Abwasser, als Kabelkanäle oder als Unterführungen, genutzt werden.
Für die Anwendung dieser Norm sollten Hohlkastenelemente mit Innenquerschnittsmaßen (W und H in Bild 1) ≤ 1 250 mm als klein (nicht tragend oder eine geringe Tragfähigkeit aufweisend) angesehen werden. Sämtliche anderen Elemente sollten als groß definiert werden. Im Allgemeinen werden die Elemente in Werken aus Normal  oder Leichtbeton hergestellt und erfordern meist eine Betonstahlbewehrung. Die vorliegende Norm behandelt weder Elemente, die aus Porenbeton hergestellt werden, noch vorgefertigte Hohlkastenelemente aus Leichtbeton mit offenem Gefüge.
Alle Elemente sind in statisch konstruktiver Hinsicht vollständig ausgebildet. Sie werden aneinander gereiht eingesetzt, so dass sich eine Gesamtkonstruktion passender Länge (einschließlich Fugen) und Tragfähigkeit ergibt.
