COMPOSITE CONDUIT CONSTRUCTION FOR LOWER COST INSTALLATIONS AND IMPROVED PERFORMANCE

Substantial reductions in material costs of conduits may be obtained by partially or fully surrounding specially designed thin-shelled core units with structurally bonded concrete or with a combination of concrete and soil-cement. Analyses are made of composite concrete conduits with side support varying from undisturbed trenches through recompacted soil to those with no lateral support. Analyses are made of controlling moments, shears, and thrusts for various angles of encasement at the bottom and sides or for encasement fully surrounding the core units. From these values, comparisions are made of allowable loads on unreinforced concrete composite conduits and of relative amounts of tensile reinforcement required in reinforced conduits. Tests are described in which performance and installations of conventional pipe sections are compared with those of composite sections under similar loads to verify previously described analyses.
