Underground powerhouse caverns for hydropower stations

Abstract

The invention discloses an underground powerhouse chamber for a hydropower station. The underground powerhouse chamber for the hydropower station comprises a powerhouse structure and a supporting structure; the powerhouse structure is positioned inside the supporting structure; the supporting structure comprises a top structure, a middle structure, a bottom structure and an integrated pump station; the top structure comprises an arc-shaped water-resisting layer; the arc-shaped water-resisting layer comprises an outer protecting layer and an inner protecting layer; the middle structure comprises a left supporting wall and a right supporting wall which are vertically arranged; the inner protecting layer is further provided with a top arc-shaped drain pipe; vertical drain pipes are arranged inside the left supporting wall and the right supporting wall; the two ends of the arc-shaped drain pipe are respectively communicated with the upper ends of the vertical drain pipes; the lower ends ofthe vertical drain pipes are connected to the integrated pump station. Therefore, the underground powerhouse chamber for the hydropower station has a reasonable structure, has a good water draining and proofing effect, and can provide better water draining performance.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower, in particular to an underground powerhouse cavern for a hydropower station. Background technique [0002] In the construction of hydropower stations, the construction of underground caverns is usually used to realize very important traffic functions such as power station operation, management, and safety inspections. After the underground caverns are completed, they also need to realize the functions of underground powerhouses. Therefore, underground caverns require a lot of Good safety drainage requirements. In the existing technology, steel formwork trolleys are usually used to pour concrete for construction. The drainage effect is poor and the drainage guarantee rate is low, which makes the workshop caverns humid for a long time, which is not conducive to the work, traffic and transportation in the workshop caverns. long run. [0003] For this reason, in view of the a...
