NOAQ Boxwall BW102 together with the BW52
Follow these instructions:
1. Inspect the area where the boxwall is to be constructed
The boxwall has been specially designed for firm, even surfaces such as asphalt, concrete,
lawns etc. It is therefore ideal for setting up on streets and paths, across car parks, in industri-
al areas, around shopping malls, in harbours and at airports. It must not be used on surfaces
that are very uneven or on ground that is prone to erosion. Inclinations of the ground of up to
1:10 is no problem, but abrupt transitions from a surface with one inclination to an other need
to be done perpendicularly. Holes or bumps should be avoided. The boxes are 992 mm long
but overlap one another, which means each box adds 900 mm to the total barrier length. A box-
wall requires a free width of 1,200 mm.
Loose sand and gravel must be brushed away from where the wall is to be erected. The
soles attached beneath each box have just as good a grip as the rubber soles on your shoes.
If there is sand on the road you run the risk of slipping, and the same applies for the boxwall.
The coupling between the individual boxes has a built-in flexibility of +/-2°, which means a
boxwall can be drawn in curves. The curv radius then becomes 26 meters.
The boxwall can be placed on land that is already flooded, but if the ground surface is difficult
to see through the water, you must take particular care to make sure that the boxes are not
placed on uneven surfaces, on the wrong side of surface water drains, etc.
The boxes are easy to handle and move, and you can also adjust the setting of a constructed
boxwall as long as the water has not started to press firmly against the base. But you must
avoid dragging the boxes on the ground, as the sealing strips on the underside are vulnerable
to wear and may become damaged.
