Description

High-strength concrete protective door

Technical Field

The invention relates to the technical field of civil air defense engineering, in particular to a high-strength concrete protective door.

Background

Due to the access of personnel and equipment, and the needs of ventilation, water supply and drainage, smoke exhaust and the like, the civil air defense basement has a small number of orifices communicated with the outside. Blast shock waves, toxic agents, biological warfare agents, radioactive particles, etc., all have the potential to enter the interior of the project from these ports to kill personnel and destroy orally engineered structures and equipment. Practice has proved that the above-mentioned various apertures are weak links in civil air defense engineering. The main components of the civil air defense mouth part comprise a protective door, a protective airtight door, a door frame wall, an outdoor channel and the like which directly bear air shock waves. The strength of the oral structure may sometimes determine the protection level of the whole work, so that the design of the oral structure is preferably reinforced in terms of both calculation analysis and construction measures during engineering design, thereby reinforcing the 'first line of defense' of the engineering protection.

The reinforced concrete protective door has the advantages of relatively low manufacturing cost, relatively convenient later maintenance and management, higher early nuclear radiation prevention capability than a steel structure civil air defense door and the like.

Among the prior art, the door body and the door frame of concrete people's air defense door are easy to corrode, the sealing strip is fixed to be changed inconveniently, after long-term use, probably cause the gas tightness between the door body and the door frame to reduce, when taking place poison gas, flue gas diffusion, will lead to gaseous follow crack in get into indoorly.
