AQUEDUCT DESIGN3The choice of aqueduct system. The two aqueducts of choice are the trough and the barrel type aqueduct. However, some of the specifications in their design are completely different and as such, require individual focus[ CITATION Bos76 \l 1033 ].The following design basically focuses on the barrel type aqueduct.The three principal loadings are from:The self-weightThe loading by the emergency vehiclesLoading by the water(during operation of the canalBeginning with the stresses that are induced on the slab(taking a trough aqueduct)The self-weight properties of the slab and the troughThe stress that is induced by the concrete=352/Nmm 0.0980665=3.43232752/kgcmThe stress induced by the steel=22450 /0.098665 /Nmmkgcm =44.1299252/kgcmThe concrete mix basically determines various parameters of the structural element and in this case, a C35 concrete mix is taken for the design purpose The density of water is 10003/kgm and designing the elements per meter run the stress induced is 10002/kgmThe size of the trough is given as 4.0m

AQUEDUCT DESIGN4BS 8110-1:1997Table 3.3The trough propertiesThe maximum depth that water is limited to flow is 1.8 meters. It is an important aspect of the design because of the thrust that the trough and slab aresubjected to. The freeboard of the water of 0.5 meters prevents the water from causing considerable damage to the traffic and the footpath.16mm S355 diameter bar is taken as the main reinforcing bar for our design purpose. The 16mm diameter is appropriate because it is the most viable among the three grades of steel. Though it does not possess the same characteristic strength as the S460 bars, it presents a comparatively cheaper option.Taking the cover of the slab as 35 due to moderate exposureThereore,assuming a slab thickness of 230mmEffective depth of the slab=230-35-8=187mmAnd the effective span of the trough=the span effective depth 4+0.187=4.187mThis results into a self-weight of (2500kg/m2 is the unit weight of reinforced concrete)0.230 2500 575 / /kgmmrunDesigning the wing walls of the troughThe total height of the wingwall,which may be simply supported between the wuingwall and the pier=1.8+0.5+0.230=2.52 mFurthermore, the wing wall may be described to span between the abutment and a pier that may be located midway through the total span that is 34 m. The 16mm diameter S355Cover =35mm
