Anti-radiation concrete shielding door and construction technology thereof

Abstract

The invention discloses an anti-radiation concrete shielding door and a construction technology thereof, and belongs to the field of anti-radiation doors. The anti-radiation concrete shielding door comprises a concrete pile, wherein a concrete wall body is fixedly mounted at the top end of the concrete pile, a center channel is formed in the middle of the concrete wall body, a sealing flange is arranged on one side of the center channel, the concrete wall body on the outer side of the sealing flange is provided with an annular concave cavity, the side wall of the concrete wall body is provided with eight filling ports, one side of the bearing plate block is provided with a clamping guide rod, one end of the clamping guide rod is provided with a fixed hinge block, the fixed hinge block is fixedly connected with the side wall of the bearing plate block, a movable hinge block is arranged at the other end of the clamping guide rod, and a clamping door and a butt joint door are arranged in the middle of the clamping guide rod. According to the anti-radiation concrete shielding door, the clamping door and the butt joint door are movably connected together in a butt joint mode through the clamping guide rod, the sealing performance in the shielding door is improved, and the situation that a human body is injured by radiation substances with high radioactivity is avoided.

Description

technical field [0001] The invention relates to the field of radiation-proof doors, in particular to a radiation-proof concrete screen door and its construction technology. Background technique [0002] With the development of industrial technology, the development of modern nuclear technology industry has become more and more perfect. Radioactive substances have been widely used in various fields since their discovery. Harmful effects can occur if the human body is exposed to doses exceeding a certain limit. To protect personnel from radiation, it is necessary to build corresponding shielding facilities. Shielding facilities are generally composed of shielding rooms and shielding doors. According to different types of radiation protection requirements, shielding doors are divided into metal (steel, lead) shielding doors, remixed shielding doors and neutron shielding doors according to materials. For the remix screen door, the door body composed of steel skeleton and concr...

AI Technical Summary

Problems solved by technology

[0003] In order to meet the special requirements of radiation protection, when selecting the door structure required by the protection process, the precision of the gap between the shielded door and the shielded door opening is very high. If the gap is too large, it will easily lead to an increase in the local radiation dose, which will endanger the health of personnel.
