Abstract

The invention discloses an adjustment tool and an adjustment system applied to integral assembling of steel lining modules of a nuclear power station. The adjustment tool includes a buttress; the buttress is further provided with a height adjusting part and a clamping part; the height adjusting part includes an adjusting bolt and an adjusting nut; a through hole is formed in the buttress; one endof the adjusting bolt is buried in a cement buttress after penetrating through the through hole; the adjusting nut sleeves the adjusting bolt in a threaded connection manner and is located between thecement buttress and the buttress; the outer diameter of the adjusting nut is larger than the inner diameter of the through hole; and the clamping part includes a U-shaped clamp which is used for clamping the buttress and a module base in a haunching area. The adjustment system is composed of a plurality of tools. The adjustment tool disclosed by the invention has the advantages of simple assembling, lower construction difficulty and convenient adjustment, and facilitates quick and accurate assembling of modules in the haunching area.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant construction, in particular to an adjustment tool applied to the overall assembly of steel lining modules of a nuclear power plant. Background technique [0002] The steel lining is one of the important components of the prestressed reinforced concrete containment of the reactor building. It is cylindrical and has a diameter of 46.8m. [0003] At present, the steel lining is actively promoting the concept of modular construction. According to the previous construction experience of steel lining in nuclear power plants, the steel lining haunching area module is mainly composed of the vertical section and the horizontal section of the haunching area. , The lower part of the module in the armpit area is welded to the upper part of the "L-shaped" thickened plate. Since the bottom plate and the "L-shaped" thickened plate are installed first, the working environment for the assembly, weldin...
