The barricade wall has a first rigid wall section with spring loaded wall extensions attached to the wall section.
Claims20
A barricade wall assembly comprising:
- a wall structure including:
- a central wall section;
- at least one wall extension located at an edge of the central wall section, the wall extension being movable between a retracted position in which a dimension of the wall structure is reduced and an extended position in which the dimension of the wall structure is increased.
A barricade wall structure for closing a tunnel passage, including:
- a central wall section;
- a plurality of wall extensions secured to one or more of top and side edges of the central wall section, the wall extensions each being movable between a retracted position and an extended position, wherein in the extended position the wall extensions cause the barricade wall structure to have a larger tunnel passage coverage area than in the retracted position.
A method of installing a barricade wall structure in a passageway,
- wherein the barricade wall structure includes a plurality of wall extensions secured to one or more of top and side edges of the central wall section, the wall extensions each being movable between a retracted position and an extended position, wherein in the extended position the wall extensions cause the barricade wall structure to have a larger coverage area than in the retracted position,
- the method comprising:
- positioning the barricade wall structure, with the wall extensions in the retracted position, at least partially across the passageway;
- and
- causing the wall extensions to move to the extended position so that the barricade wall structure extends further across the passageway than when the wall extensions were in the retracted position.
