Shore-side plant structure for hydropower station in easy-to-seep mountainous area

Abstract

The invention discloses a shore-side plant structure, in particular to a shore-side plant structure for a hydropower station in an easy-to-seep mountainous area, and belongs to the technical field of designing and manufacturing of hydraulic building subsidiary facilities. The invention provides the shore-side plant structure for the hydropower station in the easy-to-seep mountainous area, and the shore-side plant structure can effectively reduce loss, caused by extreme climates or geological disasters, to a shore-side plant, and protects life safety of an operator. The shore-side plant structure comprises a shore-side plant main body and a tail water culvert which is communicated with the shore-side plant main body, and further comprises an enclosure system, an anti-seepage system and an enhanced drainage system; the part, above the geographic horizon, of the shore-side plant main body is enclosed by the enclosure system; the part, below the geographic horizon, of the shore-side plant main body is enclosed by the anti-seepage system; submerging water which enters the shore-side plant structure is drained out of the enclosure system through the enhanced drainage system; and the tail water culvert penetrates out of the enclosure system from the lower part of the enclosure system.

Description

technical field [0001] The invention relates to a shore powerhouse structure, in particular to a shore powerhouse structure for a hydropower station in a mountainous area prone to seepage, and belongs to the technical field of design and manufacture of auxiliary facilities of hydraulic structures. Background technique [0002] In recent years, with the frequent occurrence of extreme weather and geological disasters, hydropower plant buildings have been flooded and buried, causing huge property losses and even casualties. Among them, floods and mudslides have caused the greatest harm to the safety of the plant area. . For example, cascade hydropower stations in the upper reaches of the Minjiang River in Sichuan, cascade hydropower stations on the Mianyuan River, and individual hydropower stations in the Tianwan River Basin, etc., were all submerged or washed away by floods and mudslides. The plant area and important hydraulic structures caused severe consequences such as powe...

AI Technical Summary

Problems solved by technology

For example, the cascade hydropower stations in the upper reaches of the Minjiang River in Sichuan, the cascade hydropower stations on the Mianyuan River, and individual hydropower stations in the Tianwan River Basin, etc., were all submerged or washed away by floods and mudslides. The plant area and important hydraulic structures caused severe consequences such as power outages in the plant area and even complete damage to the hydropower station.

When encountering the geology of mountainous areas prone to water seepage, if the anti-seepage treatment is not good, under the impact and pressure of floods and debris flows, the damage to the power plant on the bank of the power station will be greater and more serious.

These phenomena highlight the lack of understanding of special working conditions in the current design concept of shore powerhouses of hydropower stations, the incomplete design system and the lack of design methods
