Abstract
A method and an assembly for protecting dams according to which dehydration of the dam body is obtained as a result of the differences in temperature between the concrete structure and a steam barrier defined by a water-proof protective sheathing. The condensation water and any seeping water is eliminated by means of a drainage channel system at atmospheric pressure.
Claims16
Method for the protection and pressureless drainage of water present in a hydraulic concrete structure of a dam body and similar hydraulic works, according to which a waterproof protective sheathing is provided and stretched onto a surface of said hydraulic structure, the improvement comprising the steps of:
- providing an air space between said surface of the structure and an elastically yieldable protective sheathing defining a steam barrier;
- drawing off water from said dam body by causing the migration of the water in steam form into said air space;
- condensing said steam by contacting it with said steam barrier;
- collecting condensed water in said air space;
- and
- outwardly discharging said condensed water from said air space by non-pressurized water channel means provided on the surface of said hydraulic structure.
Assembly for the protection and pressureless drainage of water in a concrete structure of a dam body, comprising:
- a covering made of flexible water-proofing material, said covering defining a steam barrier;
- fastening means for mechanically fastening said covering to the surface of the dam body to be protected, and air space means for providing an air space for collection of condensed water between said covering and said surface of the dam body, and non-pressurized channel means for discharge of water from said air space.
