Each of the protrusions and the depressions has a complicated shape as shown in the drawing, a shape close to a natural stone, and a shape to be fitted into the adjacent block.
1A (1B, 1C, 1D) is a shape that can be fitted and assembled.
The base 1 is placed on the base 11A at an appropriate height and at an appropriate interval.
A plurality of earth retaining bodies 2 arranged in a zigzag shape protruding from 1A are provided, and the upper surface of the earth retaining body 2 is made uneven in the natural stone style, and the side part 21 also forms large unevenness of the natural stone style. The rainwater channel 3 zigzagged on the base 11A between the three
The arrangement group of the earth retaining bodies 2 prevents the permeated rainwater flow path 3 formed on the base 11A from being linear. That is, the large zigzag meandering of the rainwater flow path 3 is given by the arrangement of the earth retaining bodies 2, and the smaller zigzag meandering is given by the large unevenness formed on the side surface portion 21 of the earth retaining body 2.

[0007] As shown in FIG.
The embankment 4 is provided on the side of the base with a triangular embankment 4 slightly lower in cross section than the earth retaining body 2, and the top 41 of the embankment 4 is a straight line or a meandering curve but horizontal, and the height of the top 41 is high. Below this, the soil does not flow and accumulates in the form of a guest soil. If the flow is gentle, the soil reaches the height of the earth retaining body 2 beyond the top 41 and accumulates in the form of a cover soil. The rainwater passage 3 is provided with a drain hole 31 penetrating the base 1 vertically.
Means that the roots of the small shrubs extend into the ground through the drain holes 31 and spread into the soil and cover soil on the base 11A, and further into the ground from the adjacent drain holes 31. The soil covering block 1A is fixed on the slope by its own weight and the weight of the soil and covering soil.In addition, the rooting of planting shrubs prevents the collapse of the soil and covering soil block 1A and prevents the loss of the soil and covering soil. soil·
Even if the covering block 1A is made of concrete, the vegetation growing on the soil and covering soil will not die due to the replenishment of water by the capillary action from the many drain holes 31 provided.

As will be described later, the drainage depression 5 can be smoothly connected in the space, and the depression also functions as a drainage hole communicating with the ground. Therefore, the drainage depression is formed by the root of the small shrub through the depression. While extending underground, the rooting of planted shrubs will prevent the collapse of the soil and cover soil and prevent the loss of soil and cover soil. The cross section of the shape of the base 11A and the earth retaining body 2 of the above-mentioned soil and earth covering block 1A is substantially trapezoidal, that is, the base is formed so as to have a trapezoidal shape at any cross section. It is easy to remove the block from the production of the block.
