sandbag bunker的意思|示意

Last month, the worst flooding in 22 years caused the lagoon to rise more than 5 feet above normal, forcing tourists to bunker down in hotels and shopkeepers to put up sandbag barricades.

上个月，二十二年来最为猛烈的一次洪水让水城的水位比往年上升超过五英尺，迫使观光者逗留在旅馆内，而店主们也不得不在门外设置沙袋以阻挡洪水。

Commuters hurried along the sidewalk toward the entrance, passing a war-zone-like vision of a guard hunkered behind a sandbag bunker, his gun pointing outward.

人们朝着入口沿着人行道快速通过，像是在战区有守在沙袋后的卫兵盯着他们一样。
