Trade Journals for the Concrete Industry

A long time ago, a simple retaining wall called “Shigara“ was used in Japan (Fig. 1). This is a kind of fence which is made by bamboos and piles. The piles are placed at a certain interval and the bamboos are knitted between piles. They were mainly used for revetment and boundary. The biggest advantages of this fence were that it is made by natural materials which blend to nature and it is easy to make requiring no construction skills. Nowadays it is hard to find them but, today you can find a concrete retaining wall as like as “Shigara” instead. In this issue, the retaining wall that highly blends with the surrounding environment “Cross Beam Retaining Wall” will be introduced.
