<br />. <br /> <br />. <br /> <br />The tunnel linings were also designed to wkhstand full hydrostatic internal pressures wkh nominal <br />external confinement. The need for an energy dissipation structure has been evaluated, The <br />calculations included in Appendix J have shown that an armored stilling pool will suffice for energy <br />dissipation. <br /> <br />. <br /> <br />. <br /> <br />Reservoir sluice gates will be designed by the supplier based upon operating specifications <br />provided by the design engineer, Additional design considerations are the intake trash rack and the <br />upstream slope protection, These will be designed as generally recommended by the State <br />Engineer and the "Design of Small Dams," The District typically uses broken concrete fragments <br />for erosion and slope protection on the Julesburg Dams, This practice has occurred for many years <br />due to the relative abundance of salvaged concrete and the high cost of imported hard rock rlprap, <br />It Is proposed to use broken concrete section from the District's existing stockpiles as well as <br />concrete obtained from the demolition of concrete structures associated with the reconstruction of <br />the outlet works, The cost for this "riprap" is expected to be relatively low. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />17 <br /> <br />. <br />
