Dam foundation abrupt slope position fault replacement structure

The utility model discloses a hydraulic and hydroelectric engineering structure, especially a dam foundation abrupt slope position fault replacement structure. The utility model provides a reduce the dam foundation abrupt slope position fault replacement structure of excavation volume, including dam foundation abrupt slope and the concrete replacement body, the fault on dam foundation abrupt slope and influence area department and be provided with and wholly excavate the space includes still that the part is drawn to hollow out within a definite time, the part is drawn to hollow out and has been excavated towards the fault influence area extension on dam foundation abrupt slope from the whole space of excavating within a definite time, the concrete replacement body build whole excavate the space draw with the part hollow out within a definite time in. This replacement structure has been because between having adopted the part to draw to hollow out, this make whole excavate the space needn't be too big, just so reduced a large amount of engineering volumes, not only reduced the time limit for a project, also make the side slope in construction time stability improvement.
