为贯彻执行“平战结合”的方针,挖掘人防工事的生产潜力,自1980年起,我们进行了人防工事贮藏蔬菜的试验。人防工事为钢筋水泥结构,深7米,试验用面积约518米~2,洞内地面干燥,无渗水现象,有一个通风口。为便于贮菜进出,在入洞口的台阶上铺设铁轨,由0.5吨卷扬机牵引行车上下。洞温最高18.5～19℃(出现在8月),最低14℃(出现在1月)。洞内相对湿度最高为98％(出现在7～8月),最低为70％(出现在1～2月)。洞内空气含氧量
In order to implement the principle of “combing peacetime and wartime” and tap the potential of civil aircrew production, we have conducted trials of vegetable storage since the beginning of 1980. Civil defense fortifications for reinforced concrete structure, 7 meters deep, test area of about 518 meters ~ 2, dry ground within the hole, no water seepage, there is a vents. In order to facilitate the storage of vegetables in and out of the hole in the steps of the laying of the track, from 0.5 ton hoist traction driving up and down. Cave temperature up 18.5 ~ 19 ℃ (appeared in August), the lowest 14 ℃ (appeared in January). The highest relative humidity in the cave is 98% (from July to August) and the lowest is 70% (from January to February). The air inside the hole oxygen content
