Embodiment Construction

[0040] The present invention comprehensively analyzes various construction technologies, construction management methods and experience in the construction of nuclear island projects in the first and second rounds of nuclear power plants in my country. On the basis of the shortcomings of huge resources and huge investment in temporary infrastructure construction on site, the concept of modular construction is used to put forward the modular concept and modular design appeal for the upstream engineering design, and the traditional construction concept and construction technology are carried out in the construction stage of the project. optimized and refined. And introduce P3 plan management technology, computer three-dimensional model technology, nuclear power plant open top method construction technology, factory manufacturing concept, use the parallel construction organization method of construction and installation engineering, and carry out in-depth construction and installati...

Abstract

The invention discloses a modular construction method of a nuclear island of a nuclear power station, which comprises: a modular design step, which is to modularly design an upstream project of the nuclear island of the nuclear power station to divide a plurality of units in the nuclear island of the nuclear power station and/or combine the plurality of units to form a plurality of modules and connecting units between the modules and between the modules and the outside; a module prefabrication step, which is to prefabricate the modules in an industrial manufacturing mode; a plant building construction step, which is to construct plant buildings in the nuclear island in an open-top-method construction mode; and a module installation step, which is to install the prefabricated modules on preset design positions of the plant buildings. The method greatly increases the prefabrication rate of the industrial manufacturing of the project of the nuclear island of the nuclear power station, improves the construction quality of the project of the nuclear island, accelerates the construction process of the project and reduces overall construction cost.

Description

[0001] This application is a divisional application of the patent application with the filing date of September 27, 2007, the name "modular construction method for nuclear power plant nuclear island", and the application number 200710162906.3. technical field [0002] The invention relates to the field of nuclear power plant construction, in particular to the construction of mega-kilowatt and above large nuclear power plants. Background technique [0003] At present, in the construction of nuclear island projects of nuclear power plants that have been put into operation or are under construction in China, the traditional construction, civil engineering and installation construction organization mode is generally adopted, with the component or equipment unit as the smallest unit, and the construction is carried out according to the preset construction sequence. . It has the disadvantages of long construction period, many high-altitude operations, and complicated engineering q...
