Abstract

The invention discloses an emptying tunnel or special flood discharging tunnel arranging system and an operating and closing method thereof and belongs to the technical field of hydraulic structure design manufacture. The system and the opening and reclosing method of the system can effectively reduce hydropower station construction cost. The system comprises a diversion tunnel, the special flood discharging tunnel or the emptying tunnel and a blocking structure with an overflow device. The tail end of the inlet section of the special flood discharging tunnel or the emptying tunnel is communicated with the diversion tunnel at the back of a blocking body, and the blocking structure is arranged in the diversion tunnel at the back of the tail end of the special discharging tunnel or the emptying tunnel. The opening method includes determining the breaking load of a connection bolt, determining and manufacturing a blasting cutting explosive bag according to the breaking load, arranging the blasting cutting explosive bag at the position of the connection bolt between two connection flanges, starting the blasting cutting explosive bag to enable a detachable seal to explode and the like.

Description

technical field [0001] The invention relates to a layout system, in particular to a layout system of a vent hole or a very flood discharge tunnel, and belongs to the technical field of design and manufacture of hydraulic structures. The invention also relates to an opening method for opening said arrangement system and a closing method for closing said arrangement system which has been opened. Background technique [0002] A hydropower station generally consists of three parts: a dam, a water diversion or flood discharge structure, and a power plant. Among them, the role of the dam is to raise the water level to form a reservoir, combined with the natural drop of the river to artificially create the potential energy of the water head that can be used for hydropower generation. According to the dam materials, it can be generally divided into core rockfill dams, face rockfill dams, concrete dams and other types. Since the dam is directly in contact with the water body of the...
