There's a problem. On the other hand, lawn work does not damage the landscape, but does not provide a strong seawall. In addition, wooden fences are sometimes used as piers, but the strength and durability of the seawall have not been sufficiently enhanced.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a strong seawall with high durability without damaging the scenery such as a riverbank.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to further develop a conventional wooden fence and to provide a step-like seawall having a raised wall formed by the wooden fence.

[0005] That is, the invention of this application is a revetment embankment constructed in a step-like manner, comprising a large number of wooden fence units in which a plurality of standing timbers are connected side by side without gaps. The base formed by the steps is fixed to the slope, and a plurality of wooden fence units are arranged on the base at intervals in the slope direction of the slope so as to form a staircase, and each step is lifted. Are arranged laterally along the slope so as to be formed by a plurality of wooden fence units, the respective wooden fence units are connected to the base, and the wooden fence units are connected to each other via the base. The back of the wooden fence unit is filled with backfill material.

[0006] In such a revetment embankment, unlike the step work using a net fence adopted in the conventional hillside sabo,
Since the wooden fence unit is formed by connecting a plurality of pieces of wood without gaps, the soil retaining effect is high, and the embankment is strong and has high durability. Moreover, the fact that the wooden fence units are connected to each other via the base works advantageously on the strength of the seawall. In addition, unlike the stairs constructed by masonry, the embankment does not require masonry, so construction is easy.
