Concrete Encased Duct Bank Design

Concrete Encased Duct Bank Design. The thermal properties of the soil in which the duct bank is installed are the most critical aspect to the design As the cables generate heat it is dissipated to the surrounding soil and concrete encasement materials Conduction of heat from the cables to the surrounding materials occurs due to temperature differences between materials.

Because of factors such as defects in early design construction and nearby infrastructure deficiencies such as the differential settlement tilting and cracking of concrete and HDPE conduits can appear in electrical duct banks and working wells as shown in Figure 2 Hence protecting electrical cable duct banks and controlling their deformation and damage.
