Barricades是什么意思

A barricade is a line of vehicles or other objects placed across a road or open space to stop people getting past, for example during street fighting or as a protest.

If you barricade something such as a road or an entrance, you place a barricade or barrier across it, usually to stop someone getting in.

If you barricade yourself inside a room or building, you place barriers across the door or entrance so that other people cannot get in.
