Cofferdam water retaining structure and dismantling method thereof
The invention belongs to the technical field of water-power engineering diversion design, and particularly discloses a cofferdam water retaining structure which comprises a water retaining rock bank and a sub-weir, a foundation surface of the sub-weir is arranged at the top of the water retaining rock bank, and gaps are reserved between the foundation surface of the sub-weir and the edge of the upstream side and the edge of the downstream side of the top of the water retaining rock bank. According to the dismantling method of the cofferdam water retaining structure, the cofferdam water retaining structure is dismantled, and the water retaining rock ridge and the sub-weir are dismantled in a layering and partitioning blasting mode according to the sequence from top to bottom and from inside to outside. According to the method, dry land construction conditions can be ensured when the water inlet and the water outlet of the mixed pumped storage hydropower station are built in the existing hydropower station reservoir with the annual regulation capacity.
本发明属于水电工程导流设计技术领域，具体公开了一种围堰挡水结构，包括挡水岩坎和子堰，所述子堰的建基面置于所述挡水岩坎的顶部，且所述子堰的建基面与挡水岩坎顶部迎水侧的边缘和背水侧的边缘之间均具有间距。一种围堰挡水结构的拆除方法，对上述的一种围堰挡水结构进行拆除，所述挡水岩坎和子堰的拆除按照自上而下且由内向外的顺序进行分层、分块爆破拆除。本发明能够保证在具有年调节能力的既有水电站水库内修建混合式抽水蓄能水电站进出水口时具备干地施工条件。
