40、on Products Directive sets out Essential Requirements to be considered, depending upon the use made of the product. For box culverts it was mandated that the requirements for mechanical resistance and stability should be considered. For these requirements this standard will mainly refer to clauses o
41、f EN 1992-1-1, Eurocode 2: Design of concrete structures Part 1-1: General rules and rules for buildings. The mandate also requires consideration of durability, from the point of view of freeze thaw action and corrosion, which is also addressed by the Eurocodes referred to above. #deleted text$ BS E
42、N 14844:2006+A2:2011EN 14844:2006+A2:2011 (E) 7 1 Scope This European 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
43、 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 European Standard, box culverts having internal cross-sect
44、ional dimensions (W and H in Figure 1) less than or equal to 1 250 mm are considered as small (non-structural or light structural). All other units are defined as large.$ The elements are generally manufactured in factories using either normal weight or lightweight concrete and usually require reinf
45、orcing 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 (i
46、ncluding joints) and capacity. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.
