Scaled hydropower
A fish passage system having flexible textile materials forming a conduit to transport fish across river barriers encountered during migration. The system can include modular support structures that can be independently secured to riverbeds to form conduit supports, dams, hydropower structures, and the like.
1. A system comprising:
a plurality of modules vertically assembled to form at least one stack;
a post-tension anchor securing the at least one stack individually to a foundation on a streambed; and
wherein the at least one stack is not structurally secured or affixed to any adjacent stack, wherein the at least one stack includes:
vertical seals that are installed vertically between adjacent stacks to prevent leakage and provide a water-tight connection, and
horizontal seals installed horizontally between each of the vertically assembled modules that form the at least one stack;
a shear connector coupled to at least one module in the plurality of modules to prevent any module from sliding off the module directly above or below;
a shear key coupled to a concrete footing supporting the at least one stack to prevent the at least one stack from sliding in an upstream or downstream direction; and
a grout bag positioned between each stack and each shear key to secure each respective stack in place, wherein the grout bag can be removed.
2. The system of claim 1 further comprising a compressible gasket positioned on vertical interfaces on a downstream side of the at least one stack to prevent leakage and provide a water-tight connection.
3. The system of claim 2 wherein the compressible gasket is made of neoprene.
4. The system of claim 1 further comprising a compressible gasket positioned between the at least one stack and the foundation.
5. The system of claim 1 wherein the vertical seals and the horizontal seals are configured as compressible gaskets.
6. The system of claim 1 wherein the horizontal seals are positioned between the least one stack and its foundation and other interfaces.
7. The system of claim 1 wherein the vertical seals and the horizontal seals are made of neoprene.
8. The system of claim 1 wherein the vertically assembled plurality of modules are configured as building blocks to assemble prefabricated, modular systems for dams and hydropower facilities.
9. The system of claim 1 wherein the vertically assembled plurality of modules are configured to be stacked on top of each other to a desired height and attached together, vertically and/or horizontally, with bolted structural connections.
