Description

  TECHNICAL FIELD The present invention relates to a planting mat for cultivating plants, especially ground plants such as lawns, flowers, vegetables and the like, and a method for laying the plant mats, particularly on artificial ground such as rooftops, verandas and terraces of buildings.

  Conventionally, when a plant is planted in a place having a flat laying surface such as a rooftop of a building, a veranda, or a terrace, a waterproof layer and a root-proof layer are formed or a sheet is laid, and soil is piled thereon. In the past, ground cover plants such as lawns, plants, vegetables and the like were planted (for example, Patent Document 1).

  However, the method of laying the soil as described above requires facilities such as a waterproof layer, so that it is difficult to apply to existing buildings, but the cost burden also increases when used for new buildings. There is a problem. Moreover, in order to use said planting equipment, a large-scale operation | work is needed and will require a great deal of time and labor.

  On the other hand, it is generally said that the lifetime of the waterproof layer is 10 to 15 years, and removal work is required every time. In addition to the lifespan, if the laying surface and waterproof surface are inadvertently damaged due to planting work, etc., it is necessary to remove the plant and soil and repair the waterproof layer to prevent water leakage. This removal work also takes a lot of time and effort.

Japanese Patent Laid-Open No. 4-99411

  The present invention has been made in view of the above-described problems, and provides a planting mat that can be applied to existing buildings and does not require much time, labor, and cost for laying and removing work, and a method for laying the mat. For the purpose. Furthermore, it aims at providing the mat for planting which the management of soil and moisture is easy, and its laying method.

The planting mat according to the present invention is provided with a plurality of drainable water outlets at or near the bottom, and one or more cells that can be drained from the bottom or near the bottom so that the top opens. were recessed, a planting mat is laid directly on the laying surface, while the shape set the inwardly recessed portion in the lower portion of the required side wall of the cell, drainable through Mizuguchi is bored in the bottom of the cell The hollow concave portion is formed so as to protrude downward, and the drainage from the water passage port can be directly discharged to the laying surface . In the planting mat according to the present invention, the cell is formed in a square shape having four side walls, and the inward dent portion is formed at a lower portion of one side wall, two side walls, or three side walls of the cell. It is desirable to form the other side wall so as to be inclined inwardly from the upper part toward the lower part . Furthermore, planting mat of the present invention, the internal planting mat defining at bounding member constitutes a plurality of cells, the upper end of the height planting mat of the bounding member It is desirable to have the same height as the part .

  Further, the method for laying a planting mat according to the present invention provides the planting mat so that when the planting mat is laid on a laying surface, a space portion of a required path is formed by an inwardly recessed portion of the cell. It is characterized by laying a mat. In the method for laying the mat for planting, it is preferable that a water retaining layer is provided on the laying surface in advance before the mat for planting is laid on the laying surface. Further, in the method of laying the planting mat, when the planting mat is laid on the laying surface, a space portion of a required path is formed and at the same time, a water supply pipe is disposed in an arbitrary route of the space portion. It is good to lay the mat for planting.

  As described above, by laying a plurality of decomposable lightweight planting mats on the laying surface, it is possible to perform laying and removing operations very easily, in a short time, and without cost. In addition, a plurality of planting mats having inward dents formed in the lower part of the side wall of the cell are simply laid on the laying surface, or the cell side walls having inward dents are made to face each other and laid on the laying surface. As a result, the water supply pipe disposition space part of the required path can be formed in the lower part between the opposing cell side walls, and the workability is very good.

  Also, by forming a flat water-retaining layer on the laying surface of the planting mat, planting material (custom soil, lightweight artificial soil, etc.) is stuffed into the planting mat and seeds are planted or planted. When planting, a part of the surplus water such as irrigation or rain from the top of the planting mat is not drained to the drainage drain, but a water retention layer is formed from the water inlet formed at the bottom of each cell. The water can be absorbed and stored. And when the plant growth material in a cell becomes water-deficient, the water | moisture content of a water retention layer is guide | induced to a water flow opening by the capillary phenomenon from the opening part of a cell bottom part, and is absorbed. Therefore, the water retention layer serves as a water supply source for the plant growing material, and there is no fear of water dying, greatly contributing to the growth of seeds and plants and easy management.

  Furthermore, water can be stored in the water retentive layer by disposing a water supply pipe in the water supply pipe disposing space on the upper surface of the water retentive layer and drilling a small hole around the water supply pipe to supply water. And when the moisture of the soil stuffed in the planting mat is insufficient, the seeds or planted plants that have been soaked in the plant growth material without being dried up are absorbed from the water inlet provided on the bottom of the planting mat. Breeding can be kept good and management becomes easier.

  Since the planting mat and its laying method according to the present invention have the above-described configuration, it can be applied to existing buildings, and has the effect of not requiring much time, labor, and cost for laying and removing work. Play. Furthermore, there is an effect that it is possible to provide a planting mat that can easily manage soil and moisture and a method for laying the mat.

  Moreover, in the case of the mat 1 for planting which formed the inward dent part 4 in the lower part of three side surfaces, two side surfaces, or one side surface of the mat frame 2 (FIGS. 4 to 6, FIG. 8 to FIG. 10, FIG. 12 to FIG. 14, FIG. 16 to FIG. 18), the inwardly recessed portions 4 of the respective cells 3 are spread to face each other, whereby a substantially inverted U-shaped space portion 10 is formed in that portion, and the space in which the required path is continuous as a whole. Part 10 is constructed.

  In the example shown in FIG. 16 to FIG. 18 which is a modified example of FIG. 15, the cross-shaped substantially inverted U-shaped space 10 is formed in advance under the connecting rib 8b of the mat frame 2, so The space part 10 is additionally constructed.

  In addition, the mat frame 2 shown in FIG. 19 has only a cross-shaped substantially inverted U-shaped space 10 formed below the connecting rib 8b of each cell 3, and the space 10 continuously forms a lattice. The space part 10 is constructed.

  Furthermore, the laying method which provides the water retention layer 14 in the laying surface 13, lays the planting mat 1 on it, and arrange | positions the water supply pipe | tube 15 is demonstrated.

  In the laying method of the present embodiment, as shown in FIGS. 24 to 26, a flat water-retaining layer 14 is laid on the laying surface 13, and the planting mat 1 is laid thereon. In the illustrated example, a plurality of planting mats 1 shown in FIG. 15 are applied, and light artificial soil as a plant growing material 12 is packed in each cell 3. As the water retaining layer 14 to be laid, a woven fabric / nonwoven fabric / felt using chemical fibers or natural fibers, a water-absorbing polymer processed into a sheet shape, or a composite thereof is used.

  And when laying the mat 1 for planting, water retention is carried out in the position of the space part 10 formed in the lower part between the cross-shaped space part 10 of the lower part of the mat frame 2, and the adjacent mat 1 for planting. On the layer 14, the water supply pipe | tube 15 is arrange | positioned so that the required path | route of the space part 10 may be followed, and the planting mat 1 is spread | laid so that the water supply pipe | tube 15 arrange | positioned in the position of the space part 10 may be covered.

  That is, after a flat water retention layer 14 is formed on a laying surface 13 such as a rooftop, a veranda or a terrace, a plurality of planting mats 1 are laid down, and the lower part of the connecting rib 8b of each mat frame 2 and each cell 3 are mutually connected. A substantially inverted U-shaped space portion 10 of the required path is continuously formed in a lattice shape in the lower part.

  Thereby, it will be in the state by which the water supply pipe 15 was arrange | positioned in the space part 10, and the said space part 10 will play a very important role as the space part 10 for water supply pipe arrangement | positioning. Further, the space portion 10a also plays a valuable role as an arrangement space for the thin water supply pipe 15. The water supply pipe 15 is connected to a pressurizing device for irrigation and constitutes an irrigation device as a whole.

  The plant-growing material 12 can be stuffed into the planting mat 1 and the sowing and planting of vegetation and plants such as lawns can be carried out before or after the planting mat 1 is laid.

  By providing the water-retaining layer 14 as described above, a part of surplus water such as irrigation from the upper part, rain, etc., is stored in the water-retaining layer 14 without being drained to the drainage drain, and the plants in the cell 3 are grown. When the material 12 becomes short of water, the moisture of the water retention layer 14 is absorbed by the capillary phenomenon from the water inlet 6 of the bottom 3b. Therefore, the water retention layer 14 becomes a water supply source to the plant growth material 12 and does not have to worry about water drainage, greatly contributes to the growth of the plant and becomes easy to manage.

  And since the water | moisture content which is a plant growth condition can be suitably hold | maintained even if it reduces the plant growth material 12 used as the culture medium of a plant by presence of the water retention layer 14, a building rooftop, a veranda, a terrace, etc. The load on the laying surface 13 can be reduced.

  Further, the root of the plant coming out from the water inlet 6 in the bottom portion 3b of the planting mat 1 is located on or in the water retention layer 14 and does not deteriorate the laying surface 13, and the root prevention Also fulfills the function.

  In addition, when laying the laying surface 13 of the planting mat 1, it is possible to select an appropriate shape from among various planting mats 1, and lay it in combination with the right material in the right place.
