Abstract

The invention discloses a hydropower station tail water dredging method and belongs to the technical field of water conservancy and hydropower equipment. By means of the hydropower station tail waterdredging method, the problem about accumulation of hydropower station tail water is solved. The hydropower station tail water dredging method has the steps of 1, carrying out sludge excavation operation for hydropower station tail water accumulation; 2, carrying out sludge pumping for hydropower station tail water accumulation; and 3, separating sludge from tail water in a sludge storage tank. According to the hydropower station tail water dredging method, removed sludge is subjected to water filtering inside the sludge storage tank, water filtered out flows back to water of a hydropower station, and thus the purpose that hydropower station tail water is prevented from being wasted is achieved.

Description

technical field [0001] The invention relates to a tail water dredging method of a hydropower station, belonging to the technical field of water conservancy and hydropower equipment. Background technique [0002] After the completion of the hydropower station, the downstream channel of the dam area has experienced many times of flood discharge, washing and digging damage, and the influence of various hydraulic structures and terrain will cause a large amount of siltation in the tailrace channel and the downstream channel, thereby increasing the power generation capacity. The tailwater level affects the output of the unit. In view of these situations, strengthening the management of the tail water dredging project is of great significance for controlling the tail water level of power generation and improving the efficiency of power generation. [0003] The implementation of the excavation project for the tail water of the hydropower station can effectively reduce the river bo...
