Abstract
The invention belongs to the field of water conservancy and hydropower engineering, and mainly discloses a flood discharge and energy dissipation building foundation scooping prevention structure which comprises a dam flood discharge and energy dissipation building and a downstream river channel revetment, the dam flood discharge structure and the dam downstream river channel are each provided with a scooping prevention structure, and the flood discharge building comprises a discharge chute formed in a dam; a flip bucket is arranged at the end of the discharge chute, the energy dissipation building comprises a stilling pool and revetments on the two sides of a riverway, a first underground reinforced concrete anti-digging wall is arranged on the side, close to the riverway, of the flip bucket, and the overlapped portion of the first underground reinforced concrete anti-digging wall and a flip bucket foundation tooth groove formed below the flip bucket is fixed through connecting joint bars. Through the structure, the foundation of the flood discharge and energy dissipation building can be effectively protected from being scooped by water flow, the safety of the flood discharge and energy dissipation building is guaranteed, meanwhile, the problem that a traditional reinforced concrete scooping prevention tooth groove deep foundation is large in excavation difficulty is solved, and the foundation is an economical and safe scooping prevention facility.
Description
technical field [0001] The invention belongs to the field of water conservancy and hydropower engineering, and mainly relates to a structure and method for preventing scouring of a flood discharge and energy dissipation building and a revetment foundation of a downstream river course. Background technique [0002] In water conservancy and hydropower projects, due to the need to build dams on the river to retain water, in order to ensure the safety of the dam, it is usually necessary to set up flood discharge and energy dissipation structures. For high dams and large reservoirs, the water head is often tens to hundreds of meters, and the energy of the discharged water is huge, and the downstream river channel scours up to tens of meters. According to investigations, there are not a few buildings damaged by flood discharge and energy dissipation, and most of them are caused by the foundation being scoured by the discharge water, which leads to the instability of the buildings....
