Abstract

The invention relates to an installation apparatus and installation method for a high-temperature gas cooled reactor safety shell sealing seat, which belongs to the technical field of construction ofnuclear power project. The installation apparatus for a safety shell sealing support disclosed in the invention utilizes an internal space of the structure to avoid the influence of various inner items such as reinforcing steel bars, shielded cooling water pipes, nuclear measurement pores and the like; by virtue of the installation, adjustment and fixation of a fine adjustment mechanism and boltsfor a fixing mechanism, the high precision installation requirement can be met, and the stability and firmness of the sealing support can be ensured not to be disturbed by the later concrete pouring;and a method for installing and adjusting the sealing seat by virtue of parts and blocks is provided, so that the problem that the structure is complicated and the dense reinforcing steel bars are difficult to install can be solved. The installation apparatus and the installation method of the invention are simple in operation, convenient and feasible, the installation quality of the safety shellsealing seat can be ensured, the installation efficiency can be improved, and the installation apparatus and the installation method can be popularized and applied to the installation of large-sized horizontal buried parts in other project fields.

Description

technical field [0001] The invention relates to an installation device and an installation method for a high-temperature gas-cooled reactor containment sealing support and belongs to the technical field of nuclear power engineering construction. Background technique [0002] The high-temperature gas-cooled reactor nuclear power plant is an advanced nuclear energy technology with independent intellectual property rights and characteristics of the fourth generation technology in my country. It is one of the 16 major national science and technology projects. The reactor containment vessel is an important safety barrier for the primary circuit system, and the containment top sealing support plays a key role in connecting the containment compartment wall and the sealing cover plate, and has the characteristics of high installation precision and complex construction environment. [0003] As shown in Fig. 1(a), the sealing support 1 on the top of the containment vessel is located a...
