摘要
针对战时防护工程转入隔绝防护状态时,有毒气体沿工程口部及密闭门的各种缝隙和孔道侵入工程内部的问题,采用在工程口部的防毒通道或密闭通道内实现局部超压的方法加以解决。提出了防护工程隔绝防护口部超压的整体思路,通过分析计算密闭通道(防毒通道)超压值和超压漏气量的取值,明确了不同超压下隔绝防护时间内口部所需空气量的计算方法。试验测试证明防护工程隔绝防护口部超压技术可行。
Method of local overpressure is adopted to solve the problem that the poisonous gas could intrude into the interior of the project through the entrance when the project turns into isolation and protection state during wartime.This paper puts forward overall scheme for isolating the entrance by overpressure technology,and through the analysis and calculation of overpressure value and the air leakage of airtight passage(air lock),calculation method of required air volume during isolation under different overpressure is determined.Through the test,it is proved that the proposed technology for isolating the entrance is feasible.
