Embodiment Construction

[0051] The modular construction method of the corbel section wall proposed by the present invention is characterized in that the method comprises two parts, the making of the corbel section wall module and the construction of the corbel section wall, and the specific implementation includes the following steps:

[0052] 1) Fabrication of corbel section wall modules

[0053] The fabrication of the corbel section wall modules is completed on the off-site module fabrication steel platform (see Figure 2 ~ Figure 6 )

[0054] (1-1) Build a module to make a steel platform:

[0055] According to the overall layout of the construction and the performance of the selected crane, select a module production site that can meet the simultaneous or continuous construction of multiple modules outside the wall of the corbel section, and build a module production steel platform 8 in the area of ​​the module production site. Off-site prefabrication and assembly of wall modules in the corbel s...

Abstract

The invention relates to a modular construction method of a high temperature gas cooled reactor nuclear power plant containment bracket section wall, and belongs to the technical field of nuclear power engineering construction. The method comprises the steps that a combined module based on a steel structure is formed by construction rebars and installation parts except wall concrete, and the combined module integrates bracket section rebars, a shielding cooling water pipeline, vapor generator bearing supporting assemblies, vapor generator adjusting line rails, a bracket side face and bottom steel cladding face into a whole structure by adopting an additional steel support structure, so that construction of the bracket section wall is fully moved out of a site for whole assembly. By means of the modular construction method of the bracket section wall, the construction difficulty of a traditional construction method is solved, and the risk of construction safety is reduced; more importantly, the construction period of a critical route is greatly shortened, and the engineering quality of a containment is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of nuclear power engineering construction, and is particularly directed at the modular construction technology and process of the wall body of the corbel section of the reactor containment of a high-temperature gas-cooled reactor nuclear power plant. Background technique [0002] High-temperature gas-cooled reactor is an advanced nuclear energy technology with independent intellectual property rights and fourth-generation technical characteristics in my country. It has inherent safety features, a wide range of applications, and very broad commercialization prospects. One of the major projects is planned to be completed around 2017. The reactor containment of the high-temperature gas-cooled reactor nuclear power plant is an important safety barrier for the primary circuit system, and the difficulties in civil engineering and installation are concentrated, becoming a key path that affects the construction progr...
