BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soil retaining device used for planting on a building roof, a balcony, an artificial ground such as an atrium.

[0002]

2. Description of the Related Art In recent years, greening of rooftops and surroundings of buildings has been promoted, and planting is being done on rooftops of many buildings. Conventionally, rooftops of buildings, balconies, planting on artificial ground such as an atrium, stack blocks of concrete and use them as curbs, or assemble walls by connecting glass fiber-reinforced concrete panels, Gravel etc. is laid inside it to improve drainage, and the soil is planted on it.

[0003]

However, in the case of the above concrete block, it is heavy and therefore it takes time and labor to carry it and stacking work at the installation site, and also in the case of a glass fiber concrete panel, it is heavy to carry. It is not easy, and there are many problems such as the corners of the panel being chipped or broken during transportation.

[0004] Also, it takes time to transport the gravel laid on the inner side of the wall assembled from the blocks and panels, and when the soil layer is thin, water is replenished for planting to grow. There was a problem, so it was necessary to thicken the soil layer.

Further, as described above, the concrete blocks and panels are heavy, and since the gravel and a large amount of soil are required, the overall weight is considerably heavy. There is a problem in that it is not possible to install it on the rooftop of existing buildings, which has a large impact and is therefore overwhelmingly common.

[0006] In view of the above points, the present invention aims to facilitate transportation and assembling work by reducing the weight of the building, and to facilitate installation of the existing building on the rooftop. A soil holding device is provided.

[0007]

In order to achieve the above object, the invention according to claim 1 forms a wall portion by stacking plastic hollow blocks in a predetermined shape while connecting and fixing them in the vertical and horizontal directions. Then, a water guiding means for water retention and drainage is provided on the inner bottom surrounded by the wall, and a water permeable sheet is laid on the upper part of the water guiding means.

According to a second aspect of the present invention, the hollow block made of plastic is composed of a base block fixed to an installation surface and a wall forming block stacked on the base block. The block is configured to be provided with fitting means for connecting the base block, the wall forming block, and the wall forming block.

According to a third aspect of the present invention, in the plastic hollow block forming the stacked wall portions, one of the left and right side walls in the longitudinal direction of the hollow block located at the lowermost position is higher in one side wall. In addition, the other side wall has holes formed at positions lower than the above positions.

[0010]

According to the invention described in claim 1, since the plastic hollow block forming the wall portion is lightweight, it is easy to carry, and the wall portion is piled up while connecting and fixing the hollow blocks vertically and horizontally. Since it is formed by arranging it, the forming work can be performed easily, and since the inner bottom part surrounded by the wall part is provided with water guiding means for water retention and drainage, and a water permeable sheet is laid on it, gravel for drainage is laid. There is no need for water, and it is not necessary to thicken the soil layer for water retention, which makes it possible to reduce the weight as a whole.

According to the second aspect of the present invention, the hollow block made of plastic is composed of a base block fixed to an installation surface and a wall forming block stacked on the base block. Since the structure block is provided with the fitting means for connecting the base block, the wall forming block and the wall forming block, the base block, the wall forming block and the wall forming block are fitted to each other. The wall portions can be easily formed by connecting them together.

According to the third aspect of the invention, of the left and right side walls in the longitudinal direction of the plastic hollow block located at the bottom, one side wall is at a high position and the other side wall is at a lower position than the above position. Since holes were formed at each position,
By setting the plastic hollow block located at the bottom so that the side wall at the higher position is outside the wall, the water inside the wall will come to the inside wall of the plastic hollow block at the bottom. When the water inside the hollow block made of plastic is retained from the lower hole formed and the amount of water in the block exceeds the hole formed on the outer side wall, the water is drained from this hole to the outside of the wall.
