Construction method for excavating water inlet and outlet of pumped storage power station
The invention relates to a construction method for excavating a water inlet and a water outlet of a pumped storage power station, which comprises the following steps of: constructing a cofferdam structure on the inner side of a wading slope toe, and pumping out water in the cofferdam structure; shed tunnel structure construction is conducted on the part, located in the cofferdam structure, of the wading slope toe; and opposite excavation is conducted on the inlet of the shed tunnel structure and the outer side of the wading slope toe, and excavation work of the water inlet and the water outlet is completed. Cofferdam structure construction can be conducted on the inner side of a wading slope toe, preparation is made for shed tunnel structure construction, then opposite excavation can be conducted at the entrance of the shed tunnel structure and the outer side of the wading slope toe at the same time, excavation work of a water inlet and a water outlet is completed, large-scale slope cutting is not needed for construction of the cofferdam structure and the shed tunnel structure, the construction workload is reduced, and the construction efficiency is improved. The cost is saved; the original landform is kept before and after construction, the ecological disturbance is less, and the environmental damage is less; the two ends of the water inlet and the water outlet are excavated simultaneously, and the construction period is short.
本发明涉及一种抽水蓄能电站进出水口开挖的施工方法，其包括以下步骤：在涉水坡脚的内侧进行围堰结构施工，并将围堰结构内的水抽出；在涉水坡脚位于围堰结构内的部分进行棚洞结构施工；在棚洞结构的入口和涉水坡脚的外侧进行相向开挖，完成进出水口的开挖工作。可以在涉水坡脚的内侧进行围堰结构施工，为棚洞结构施工做好准备，随后即可在棚洞结构的入口和涉水坡脚的外侧同时进行相向开挖，完成进出水口的开挖工作，其围堰结构和棚洞结构施工无需大规模切坡，降低施工工作量，从而节约成本；施工前后保持原始地形地貌，对生态扰动较少，对环境破坏较小；施工工序成熟，进出水口两端同时开挖，其工期短。
