The trap door is arranged in two sliding parts (1 a, 1 b) with sliding capacity, where the sliding parts are assembled in the modules. The sliding parts are located at one of two ends of the shelter, where the sliding parts are closed by a wall. Length of the trap door is roughly equal to half of length of the modules.</p> |
