Washing box for manual washing of motor cars and lorries

摘要

The washing box (1) has a bottom slab for draining away the water and roughly vertical side walls along the long sides. The box consists of one or more prefabricated concrete components (2,3). The prefabricated concrete components (2,3) may have the same cross-section. Alternatively, the box may be composed of two L-shaped or T-shaped side components and a middle piece (10) between them, with the joints between the components running longitudinally.
