  Furthermore, an irrigation pipe 15 for irrigating the vegetation layer 8 is provided on the scattering / transpiration preventing layer 13. As the irrigation pipe 15, a pipe made of polyvinyl chloride in which irrigation holes were formed at predetermined intervals on the bottom along the longitudinal direction was used.

  Next, an example of the greening method according to the present embodiment will be described with reference to FIGS.

  As shown in FIG. 2, first, the formation frame body 5 having an arbitrary size is set according to the wall surface or artificial ground to be greened, and the metal strength (material strength, The number of column frames 3, the number of surrounding frames 4, the installation interval of the surrounding frames 4, etc.) are determined. The size of the forming frame 5 is normally set such that the height H is 1 m or less, the width W is 0.5 m or less, and the length L is about 1 to 2 m.

  For the bottom frame 2, two parallel L-shaped hardware 2 a and 2 b each having a connecting member 21 for coupling the column frame 3 to both ends are used, and the inner surfaces of these L-shaped hardware 2 a and 2 b face each other. Arrange to do.

  An insertion hole for inserting a part of the connecting member 21 is formed in the bottom of each column frame 3 in advance. In order to reinforce the forming frame body 5 in accordance with the size of the forming frame body 5, a reinforcing frame R is attached in advance to the inside of the surrounding frame 4.

  The prepared support frame 3 is erected, and the surrounding frame 4 with the reinforcing frame R is attached at a predetermined interval in the height direction of the support frame 3 to obtain the formation frame main body 5b. The enclosure frame 4 and the reinforcing frame R may be attached by using a wire or by welding.

  As shown in FIG. 3, the forming frame main body 5b is placed on the L-shaped hardware 2a, 2b so that the support frames 3 are in contact with the inner bottom surface and the inner surface of the L-shaped hardware 2a, 2b. The support frame 3 is connected and fixed to the hardware 2a and 2b, respectively, and the formation frame 5 is obtained.

  In the present embodiment, as the connecting member 21, as shown in the enlarged plan view of the J portion in FIG. 3, a substantially U-shaped screw that circumscribes and engages the outer peripheral surface of one column frame 3. A shackle comprising a member 22 and a nut 23 screwed to both ends of the screw member 22 and screwing the screw member 22 to the L-shaped metal piece 2b was used.

  As shown in FIG. 4, a waterproof sheet 9 is laid on the bottom of the forming frame 5. In the present embodiment, the waterproof sheet 9 is laid from the bottom surface of the forming frame 5 to a height of about 10 cm.

  As shown in FIG. 5, an outer mesh sheet 6O is provided inside the waterproof sheet 9, and as shown in FIG. 6, an inner mesh sheet 6I is provided inside a predetermined distance from the outer mesh sheet 6O. The inner and outer mesh sheets 6I and 6O may be provided by folding one mesh sheet on the bottom surface along the entire inner peripheral surface of the forming frame 5, or one for each surface of the forming frame 5. One sheet may be provided, or one sheet may be provided for each interval of the reinforcing material R.

  Thereafter, a water retention / drainage layer 10 (see FIG. 1) is provided in the waterproof sheet 9, a moss layer 11 is provided between the inner and outer mesh sheets 6I, 6O, and the water retention / drainage layer 10 on the inner side of the inner mesh sheet 6I. The core material 12 (see FIG. 1) is provided except for the upper part of the forming frame 5. In the present embodiment, the core material 12 is provided except for the upper portion of the forming frame 5 of about 10 cm. Before the core material 12 is put into the forming frame 5, the drainage artificial soil, the bark material and / or the coal char, and the water retention material are mixed in advance until the whole becomes dark.

  An outflow prevention layer 14 (see FIG. 1) is provided on the core 12, a scattering / prevention layer 13 is provided on the outflow prevention layer 14, and finally an irrigation tube 15 ( 1). When the plant p is planted at least on the moss layer 11 from the front and both sides, and the plant p is planted in the scattering / transpiration preventing layer 13, the greening block 1 shown in FIG. 1 is obtained. The plant p grows stably by extending absorption roots into the core material 12 and extending stems and trunks through the meshes of the inner and outer mesh sheets 6i and 6O that form the inner wall of the forming frame 5. Depending on the installation location of the greening block 1, the plant p may be planted on the back surface of the moss layer 11.

  The L-shaped hardware 2a, 2b, which is the bottom portion of the forming frame 5, is attached to the above-mentioned wall surface or artificial ground, for example, a continuous attachment surface of a building eave or fence, and one or more greening blocks 1 are installed. By doing so, the walls and artificial ground are greened.

  Thus, according to the greening block 1, the waterproof frame 7, the mesh layer 6 with the upper part opened, and the vegetation layer 8 are provided in the formation frame 5 using the formation frame 5 that is open in six directions. Therefore, the plant p can be planted also on the top end portion and the rising side surface of the greening block 1.

  Furthermore, since the greening block 1 can be handled in blocks after it is assembled, it can be easily installed or removed.

In the tree planting block 1, the waterproof sheet 9 is laid on the bottom of the forming frame 5, and the mesh sheets 6I and 6O having different meshes are stacked on the waterproof sheet 9, thereby preparing for temporary storage of rainwater or continuous water supply. . In the greening block 1, the water retention / drainage layer 10 in the waterproof sheet 9 supports the weight of the core member 12, and also serves as a temporary water tank. This greening block 1 has a weight of about 1/3 of normal soil and a weight of about 0.5 t per 1 m ³ when water is supplied.

  Therefore, according to the greening block 1, the greening of the wall surface and the artificial ground is lightweight and has good water retention, and the entire forming frame (planting basket) 5 can be made green. The effect can be expected, and unlike conventional concrete, masonry, etc., it is possible to realize an enclosure made up of almost organic matter, and to provide things closer to natural green.

  Moreover, in the greening block 1, the greening block 1 is installed mainly by the moss layer 11 by making the vegetation layer 8 which is a planting base layer into a two-layer structure of at least the moss layer 11 and the core material 12. Planting of the plant p later becomes easier, and the depth of the growth layer of the absorption root to which the plant p mainly replenishes the nutrients, and the whole of the vegetation layer 8 is spread without stagnation of water, air and nutrients, Weight reduction can be achieved.

  In the tree planting block 1, the scattering / transpiration prevention layer 13 prevents the scattering of the core material 12 which is a lightweight material due to the wind, and the soil quality is changed from the core material 12, thereby increasing the moisture from the ground. It is suppressed.

  This scattering / transpiration prevention layer 13 is a stable layer of natural soil (such as soil itself and microorganisms in the soil) that gradually lowers the layer even when considering the overall diversity of the greening block 1 in the near future. It melts to the core material 12 side, which is an artificial material, and contributes to the stability of the artificial material.

  As a result of experiments in which the inventor planted perennial and bulbous plants as plants p in the greening block 1 and regularly supplied water to the irrigation pipe 15 with rainwater or some water, some flowers bloomed throughout the spring, summer, autumn and winter. It was confirmed that the greening block 1 was a three-dimensional lump with colorful autumn leaves.

  In addition, according to the greening method according to the present embodiment, the wall and artificial ground can be greened easily using the greening block 1 while using existing materials and parts, so that the construction is quick and low cost.

  Here, the effects of the greening block 1 are summarized below.

  1) The construction is quicker than the planted ridge constructed by conventional concrete, masonry, etc., and can be shortened to about 1/4 of the conventional construction time.

  2) The water retention is high, the use of rainwater is greatly improved, and rainwater can be stored, thus contributing continuously to the mitigation of heat islands.

  3) Since the top, side, and head can be used as a planting space, the whole is beautiful and has a great visual healing effect as a mass of plants with little discomfort.

  4) Existing equipment such as paved roads can be placed in a table without damage. Therefore, it is suitable for temporary and urgent responses such as partitioning a wide space according to the purpose.

  Next, an example of the planting structure (greening structure) using the greening block 1 will be described with reference to FIGS.

  As shown in FIG. 8, a plurality of greening blocks 1 are arranged in a straight line to form a planting structure 81, or a plurality of greening blocks 1 are arranged in a frame to form a planting structure 91 as shown in FIG. It can be greened with a high degree of freedom according to the shape and situation of the wall and artificial ground. In the case of the planting structure 91, since the space S9 is partitioned in the frame, this space S9 can be used as a planting space.

  As shown in FIGS. 10 and 11, the planting structure 101 is provided with a plurality of greening blocks 1 on the wall surface W10 of a building B such as a building or a condominium, and the greening block 1 and an artificial ground 102 such as a rooftop, A water supply means 104 for supplying excess rainwater from the artificial ground greening structure 103 to the greening block 1 is connected to the artificial ground greening structure 103 planted with plants p10 such as turf and trees. .

  The artificial ground 102 is obtained by providing a rooftop waterproof layer 106 on the slab concrete 105 provided at the top of the building B, and providing protective concrete 107 on the rooftop waterproof layer 106. The surface of the protective concrete 107 is appropriately inclined so that rainwater or the like is drained from a drainage pit 108 provided on the artificial ground 102. An expansion joint 109 is provided between the adjacent protective concrete 107. The expansion joint 109 is a joint that absorbs expansion and contraction of the protective concrete 107 due to a temperature change of the outside air, and prevents the protective concrete 107 from cracking.

  On the protective concrete 107 of the artificial ground 102, a root-proof sheet (also having a waterproof function) 110 that prevents the root of the plant p10 from entering the roof-side waterproof layer 106 is laid, and water retention such as a sponge is provided on the root-proof sheet 110. If the means 111 is provided, the mesh sheet 112 is provided on the water retaining means 111, the granular artificial improved soil 113 is embanked on the mesh sheet 112, and the plant p10 is planted on the artificial improved soil 113, the artificial ground greening structure 103 is obtained. It is done.

  Since the waterproof parapet 114 and the fall prevention fence 115 are provided between the artificial ground 102 and the wall surface W10 of the building B, a water supply hole 104a is formed at the lower end of the waterproof parapet 113, and also on the water supply hole 104a. A root-proof sheet 110 is laid, a horizontal water supply pipe 104h along the horizontal direction of the wall surface W10 is provided at the outlet of the water supply hole 104a, and a vertical water supply pipe 104v along the vertical direction of the wall surface W10 is provided at the horizontal water supply pipe 104h. The vertical water supply pipe 104v and the irrigation pipe 15 of each greening block 1 are connected to each other.

  Thus, according to the planting structure 101, the water supply hole 104a, the horizontal water supply pipe 104h, and the vertical water supply pipe 104v constitute the water supply means 104, and the water supply means 104 connects the artificial ground greening structure 103 and the greening block 1 with each other. By connecting, rainwater that could not be used in the artificial ground greening structure 103 can be used effectively, and natural greening can be performed even in places with a head.

  Urban architecture is now like a concrete box. The material is dry and the light is diffusely reflected in light and sound. In addition, the water retention function is lacking in the whole city, and the weather is disturbed due to sudden floods and heat island phenomenon due to heat accumulation of materials, making it difficult to live.

  For this reason, it is now necessary to devise a method for securing a certain amount of rain on the rooftop for a certain period of time and gradually flowing it to the wall greening.

  Between rooftop greening and wall greening, waterproof parapets and fall prevention fences are currently installed, which is the biggest obstacle to effective use of rainwater.

  As described above, the greening block 1 has a function of gently sucking out rain that has fallen on the rooftop greenery and connecting it to wall greening. That is, the greening block 1 has a shape secured by the inner and outer mesh sheets 6I and 6O and the moss layer 11 up to a certain height to prevent falling, and does not collapse for a long time.

  Moreover, according to the planting structure 101, a fixed amount is not stored on the rooftop on the waterproof surface, but it is possible to prevent flooding of the artificial ground greening structure 103 due to overflow by flowing gently through each greening block 1 on the greened wall surface.

  Furthermore, instead of the waterproof parapet 114 and the fall prevention fence 115 shown in FIG. 10, the greening block 1 is used, and the greening block 1 is used as a waterproof parapet and a fall prevention fence that had to be installed conventionally. You can also.
