Retaining wall or acoustic barrier constructing method, involves supporting vertical holes of planks and crossbars on corresponding crossbars and planks so that holes are aligned during superimposition of crossbars and planks

摘要

The method involves superimposing crossbars (3) and planks (2) so that each plank rests on two different crossbars at two points and each crossbar rests on two different planks at two points. Vertical holes of each plank and each crossbar are supported on corresponding crossbars and planks so that the holes are aligned during superimposition and passage of a bonding unit between the planks and crossbars is allowed.
