Abstract

The invention discloses a nuclear power station water intake open channel trash holding construction method. The method is characterized in that diversion dikes are arranged on the two sides of a water inlet, a trash holding structure is arranged in the middle of each diversion dike, each trash holding structure is mainly composed of a plurality of parallel water intake culverts, an intertidal trash holding net is arranged above the water intake culverts, a plurality of special trash holding net cages are arranged in the water intake culverts, and a movable portal crane is arranged above the trash holding structure. According to the nuclear power station water intake open channel trash holding construction method, the problems existing in an existing conventional trash holding scheme can be effectively solved, the holding strength is improved, underwater operation and manpower use are greatly reduced, the fishing and cleaning efficiency is improved, and the project investment and the operation and maintenance cost are saved.

Description

technical field [0001] The invention relates to a method for constructing an open channel for taking water in a nuclear power plant and belongs to the technical field of cold source protection for nuclear power plants. Background technique [0002] The operation of nuclear power plants will generate a lot of heat, and a reliable cold source must be provided for cooling to ensure the safe and stable operation of the power plant. The existing domestic nuclear power plants are all coastal power plants, using seawater as a cold source, and exporting more than 60% of the heat generated during unit operation through the process of "suction→heat exchange→discharge". Most nuclear power plants in China use open channels for water intake. In order to ensure reliable water intake, most nuclear power plants are equipped with multiple filtering equipment at the entrance or in the open channel for water intake, including trash nets, oil drifts, coarse grids, trash net pockets, and thick a...
