Example Embodiment

[0040] The present invention comprehensively analyzes various construction technologies and construction management methods and experiences in the construction of nuclear island projects in China's first and second rounds of nuclear power plants. It overcomes the long construction period of the nuclear island project construction mode of existing nuclear power plants, and puts manpower and construction machinery on site. Based on the shortcomings such as huge resources and huge investment in temporary infrastructure construction on site, the concept of modular construction is used to propose modular concepts and modular design requirements for upstream engineering design, and carry out traditional construction concepts and construction techniques during the construction stage of the project. Optimized and refined. It also introduces P3 planning management technology, computer three-dimensional model technology, nuclear power plant open-top construction technology, and factory ma...

Abstract

The invention discloses a modularization construction method for a nuclear power station nuclear island, comprising the following steps: a modularization design step, carrying out the modularization design on an upstream engineering design of the nuclear power station nuclear island so as to divide and/or combine a plurality of units in the nuclear power station nuclear island into a plurality of modules and connecting units among the modules and between the modules and the outside; a module prefabrication step, prefabricating each module in a workshop manufacturing manner; a workshop building step, building workshops of a nuclear island building by an open-top construction method; and a module installation step, installing the prefabricated modules at the pre-designed positions of the workshops. The invention greatly improves the prefabrication rate of workshop manufacture of the nuclear power station nuclear island engineering, improves the construction quality of the nuclear island engineering, accelerates the engineering progress and achieves the purpose of reducing the whole 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...
