A kind of anti-radiation concrete screen door and its construction technology

Abstract

The invention discloses a radiation-proof concrete screen door and a construction process thereof, which belong to the field of radiation-proof doors, and comprise a concrete pile, a concrete wall is fixedly installed on the top of the concrete pile, and a center is arranged in the middle of the concrete wall. channel, and one side of the central channel is provided with a seal overturn, and the concrete wall outside the seal overturn is provided with an annular concave cavity, the side wall of the concrete wall is provided with eight filling ports, and one of the load-bearing plates An engaging guide rod is provided on the side, one end of the engaging guide rod is provided with a fixed hinge block, the fixed hinge block is fixedly connected with the side wall of the load-bearing plate, and the other end of the engaging guide rod is provided with a movable hinge block, A clamping door and a docking door are arranged in the middle of the engaging guide rod. In the present invention, the clamping door and the docking door are moved and docked together by the engaging guide rod, which improves the sealing performance in the shielding door and prevents the human body from being harmed by highly radioactive radiation substances.

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.
