Description

Technical Field

[0001] The invention relates to the technical field of nuclear power plant construction, and in particular to a shielding steel plate embedded part and S-shaped casing group structure and an installation construction method. Background Art

[0002] The shielding room of a nuclear power plant has requirements for the shielding function of the room and needs to install an exhaust system. Usually, an S-shaped casing is left inside the wall. The S-shaped casing inside the wall occupies a large space. Its traditional construction embedded parts are small and light in weight. Most of the reinforcement forms are through the anchor claws of the embedded parts and the wall steel bars tied together. Once the binding is completed, it is basically finalized. If the traditional embedded reinforcement method is used, it cannot be installed in place.

[0003] Moreover, since the installation of the S-type casing weakens the thickness of the heavy concrete wall, it will affect the radiation shielding function. In order to prevent radiation leakage, the S-type casing of the shielding room needs to be shielded and strengthened. Therefore, the S-type casing needs to be constructed, installed and shielded with large shielding steel plate embedded parts. The large shielding steel plate embedded parts are large in size and heavy in weight. After the conventional construction concrete pouring is completed, the installation accuracy of the shielding steel plate cannot be guaranteed. Summary of the invention
