Abstract

The invention provides a transformation scheme of a water sluice gate groove of a material change pond of a nuclear power plant. The scheme relates to a gate groove, a water sluice gate groove sealing panel which is used for building a sealing face of a water sluice gate sealing air bag on the basis of the gate groove, and a leveling device used for adjusting the position of the water sluice gate groove sealing panel. By means of the transformation scheme of the water sluice gate groove of the material change pond of the nuclear power plant, the position of the water sluice gate groove sealing panel can be conveniently and fast adjusted, and therefore the flatness of the sealing face of the water sluice gate sealing air bag finally formed after transformation can be guaranteed.

Description

technical field [0001] The invention relates to a modification scheme for a water gate groove of a refueling pool in a nuclear power plant. Background technique [0002] Such as Figure 1-3 As shown, the water gate of the refueling pool of the nuclear power plant generally adopts an inflatable sealing structure. Two sealing airbags 02 are arranged on the U-shaped sealing surface 031 of the water gate 03, and the inside is filled with nitrogen gas of about 0.25MPa. The steel cladding of 01 is pressed against 011 to form a complete watertight boundary. If necessary, the water on the side of the pressure vessel can be emptied, and operations such as repairs to the flange surface of the pressure vessel can be performed. In order to ensure the sealing effect, it is necessary to ensure the flatness of the sealing surface of the sluice gate and the sealing surface of the door slot. The sluice gate is manufactured in the factory, and the flatness of its sealing surface can be guar...
