To enhance a safety countermeasure by eliminating the problem wherein a conventional CB (concrete block) wall frequently collapses in an earthquake, and is not easy in reduction of damage, refuge and a rescue to people by the collapsed heavy weight CB.

This construction method for stacking up a high-quality W.B (wood block) product by machining a long-short size member of processing-drying a thinning material, is performed as a construction method for stacking up on an upper stage via a tongue by dropping in and fixing an upper stage W.B by fixing the tongue (relay timber) to the W.B upper end for a sill fixed to a foundation, and a collapse preventive construction method for bracing an anchor bolt with a hook fixed to an upper part and an independent foundation of a stacked-up W.B fence by a wire with a turnbuckle by stacking up on the upper stage by the same method for fixing both upper and lower ends by dropping an upper stage W.B in between columns by fixing the tongue to the sill upper end by simultaneously fixing a sill and column W.B to a foundation, to provide environment-friendly town making and a scenery by construction of the W.B fence for reducing damage of an earthquake, facilitating refuge and rescue, protecting mountains and forests by the spread of the W.B fence, recovering water resources and promoting employment.
