<p>A structure (1), such as a portable cabin, a temporary building, a bridge and a vehicle, is provided that has means designed to counter the forces created by blast landmines and improvised explosive devices deployed beneath, adjacent or in the path of the structure (1). The structure (1) comprises a body (2) defining an under-surface (3), which may be wedge-shaped, and side surfaces (4). At least one inclined or curved first deflector (5) is secured to the structure (1) and positioned where the under-surface (3) and one or more side surfaces (4) meet to define a channel (6) between itself and the structure (1) through which blast ejecta from said explosion is channelled in a generally upwards direction. A deflecting means (7, 20, 25) is located within or without the channel (6) and is adapted to deflect or to entrain blast ejecta and align its flow with or in a direction towards a longitudinal axis of the channel (6). The deflecting means (7, 20, 25) may comprise at least one second deflector (7, 20) that extends at an angle to the first deflector (5) to deflect impacting blast ejecta and thereby align its flow with or in a direction towards the longitudinal axis of the channel (6). Alternatively or in addition the deflecting means (7, 20, 25) may comprise at least one ejecta accelerator (25) that is adapted to entrain blast ejecta and to align its flow with or in a direction towards the longitudinal axis of the channel (6).</p> |
