Description

  The present invention relates to a greening system including a container for providing a water storage section between an installation surface on which a greening system is installed and a soil layer on which plants are planted, and a construction method thereof. The present invention relates to a greening system that can be prevented and a construction method thereof.

  Conventionally, in order to maintain a moist state suitable for plant growth, a growth method has been used in which a water storage portion is provided with a non-permeable plastic sheet below the growth layer (for example, Japanese patent publication regarding grass growth). H11-75531).

  In addition, in order to prevent the plant from withering, a planting unit or planter is installed between the non-flat roof and the soil layer to provide a greening structure of the roof (for example, Japanese Patent Publication 2004). -1,37895 publication), a heat insulation block provided with legs for forming an air layer and capable of growing plants has been used (for example, see Japanese Patent Publication No. 2003-147873).

  Furthermore, a prismatic air layer is formed between the lower corrugated plate and the upper corrugated plate by arranging the corrugated plates having different heights on the support member forming the roof skeleton. In addition, a green roof having excellent waterproofness and heat insulation has been used in which a water storage portion is formed by providing a damming portion in the concave portion of the upper corrugated plate (for example, Japanese Patent Publication No. 2001-16982). See the official gazette).

  However, in the case where only the water storage part is provided without providing an air layer, it is necessary to form a heat insulating layer using a separate heat insulating material so that the plant does not heat up due to heat from the lower part.

  In addition, in order to form an air layer using a planter-like unit or the like on a non-flat roof, it is necessary to manufacture a planter-like unit that matches the shape of the individual roof, and an air layer is formed using a heat insulating block. Took a lot of effort to install the insulation block.

  Furthermore, in a green roof using corrugated plates, it is necessary to process a plurality of damming portions on the plate in order to form a water storage portion, and it is also necessary to cover open portions of the end portions such as air layers. It was. In addition, it is necessary to fix the upper plate and the lower plate with bolts or the like at the time of construction, and there is a problem that complicated work is required. Moreover, with such a structure in which corrugated plates are superposed, it is difficult to process the plates according to the size and shape of the location where the greening system is installed, and especially at the end of the installation location, the air layer and the water storage There was a problem that it was difficult to process the part.

  The present invention provides a greening system that uses a container for a greening system that can be easily processed and that is easy to construct and that is excellent in waterproofness, water retention, and heat insulation, and a method for constructing the greening system.

  That is, the greening system of the present invention includes a soil layer for planting a plant, a water-permeable soil layer support part that supports the soil layer, and a water storage part that supports the soil layer and the soil layer support part. And a water container part having a lower air layer, wherein the water container part forms the air layer between the container units by stacking at least two container units, and the uppermost container The water storage part is comprised by the unit, The said container unit has at least 2 container shape part which can become a water container, respectively, It has connected with each other, It is characterized by the above-mentioned.

  Moreover, the construction method of the greening system of this invention supports the soil layer for planting a plant, the water-permeable soil layer support part which supports the said soil layer, the said soil layer, and the said soil layer support part. A method for constructing a planting system for growing plants, comprising a water container part having a water storage part and an air layer below the water storage part, and connecting at least two container shape parts each capable of becoming a water container to each other By arranging the container units in a stacked manner at least in two stages, the air layer is formed between the upper and lower container units, and the uppermost container unit is used as a water storage part to form the water container. The soil layer support part supported by the water container part is installed, and the soil layer supported by the soil layer support part is installed.

  According to the greening system of the present invention, the container shape portion of the container unit located at the uppermost stage of the water container portion serves as a water storage portion, so that water is supplied to the soil layer via the soil layer support portion, or the soil layer Excess water can be drained to keep the soil layer at the proper humidity. In addition, since an air layer is formed between the stacked container units, the heat insulation effect of the air layer can be prevented even when the installation surface becomes hot, and the plant container unit in the lowermost stage Water will not leak even if it is damaged during construction. In addition, by increasing the number of container units or the number of container-shaped parts, a plurality of divided water storage parts can be provided, so it is easier to install a greening system on an inclined part than a single container with the same depth. In addition, it is possible to increase the amount of water retained in the water storage section. In addition, by increasing or decreasing the number of container units, it is possible to flexibly cope with the installation surface shape of the greening system, and it is not necessary to provide a large container for accommodating individual water containers, so that construction can be facilitated.

  Here, if an adjacent overflow part that allows water to overflow outside the container unit is provided at a predetermined location of the container unit, the amount of water retained in the water storage part is made constant, and excess water is stored. Can be discharged from the section.

  Further, the shape of the container shape portion of the stacked container unit is set so that the container shape portion of the upper container unit is entirely accommodated in the container shape portion of the lower container unit. If the shape is shallower than the container shape portion of the container unit, it is difficult for stagnation to occur in the overlapping portion with respect to the pressure from above, and an unpleasant squeaking sound is generated even if a person walks on the greening system. It does not occur. Moreover, the thickness which a water container part occupies in a greening system can be made thin.

  Furthermore, the shape of the container shape part of the stacked container unit is set so that the container shape part of the upper container unit is partially accommodated in the container shape part of the lower container unit. If the shape is the same as the container shape portion of the container unit, the gap formed by the upper container unit portion protruding from the lower container unit also acts as an air layer, so that the heat insulation effect is enhanced. Further, the container unit can be mass-produced at a low cost and can be easily manufactured.

  Moreover, the water container part is configured by stacking at least two stages composed of a plurality of the container units juxtaposed in the lateral direction, and at least of the at least two stages of the container units constituting the water container part. Adjacent parts are arranged in a single stage so that the positions of adjacent parts adjacent to each other in the horizontal direction in the same stage do not overlap the adjacent parts of the container units in the upper or lower stage. Therefore, it is possible to prevent plant roots from entering without providing a root-resistant layer such as a root-resistant sheet. In addition, by stacking the container units in this way, the container units in the horizontal direction are connected and fixed by the stacked container units. It can be made unnecessary.

  In addition, if the container unit is formed by molding a plastic sheet, it is possible to flexibly cope with the installation surface shape of the greening system, and it is possible to reduce the weight and facilitate the construction work.

  In addition, according to the construction method of the present invention, it is possible to construct a greening system that is excellent in heat insulation, waterproofness, water storage, and can flexibly meet installation conditions by a simple operation of stacking at least two container units. it can.

  Further, the water container part is configured by stacking at least two stages in which a plurality of the container units are juxtaposed in the lateral direction, and at least two stages of the containers configuring the water container part when the container units are stacked. At least one stage among the units, the container units arranged on the same stage are arranged so that the positions of adjacent parts adjacent to each other in the horizontal direction do not overlap with the adjacent parts of the container units on the upper or lower stage. By constructing, the gap between the joints can be closed, so that the root of the plant can be prevented from entering between the containers without providing a root-resistant layer such as a root-resistant sheet. In addition, since the container units in the horizontal direction are connected and fixed by the stacked container units, it is not necessary to fix the container units in the horizontal direction, and the greening can be performed more easily and stably. The system can be constructed.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a partially omitted sectional view showing a longitudinal section of an embodiment of a greening system according to the present invention. FIG. 2 is a plan view of a container unit constituting the water container portion of the greening system shown in FIG. FIG. 3 is a front view of a container unit constituting the water container part of the greening system shown in FIG. FIG. 4 is a plan view schematically showing the arrangement relationship of the container units in the water container shown in FIG. FIG. 5 is a front view for explaining how the container units are stacked in the water container shown in FIG. 6 is a partially omitted cross-sectional view showing a vertical cross section of the water container portion shown in FIG. 1 along the line AA in FIG. FIG. 7 is a partially omitted sectional view showing a longitudinal section of a water container portion in another embodiment of the greening system according to the present invention.

  A greening system 1 according to an embodiment of the present invention shown in FIG. 1 includes a soil retaining 2 surrounding an outer periphery of a greening area, a soil layer 4 in which turf 3 is planted inside the soil retaining 2, and a soil layer 4 A water-permeable soil layer support portion 10 that supports the soil layer 4 and a water container portion 20 that is disposed on the installation surface 5 inside the retaining clasp 2 and supports the soil layer 4 and the soil layer support portion 10.

  Here, a structure for holding the soil layer 4 can be used for the earth retaining 2, and for example, a concrete block such as a decorative block can be used.

  For the soil layer 4, soil suitable for the plant to be planted can be used, for example, system soil that is soil whose air permeability and moisture retention are adjusted according to the plant to be planted. Thereby, a plant can be grown in a soil environment suitable for plant growth.

  The soil layer support portion 10 can be made of a water-permeable material that can support the soil. For example, the soil layer support portion 10 is composed of a resin net 12 and high-functional coal such as regenerated coal 11 stacked thereon. Is configured. By providing the soil layer support portion 10 in this way, it is possible to prevent the soil from falling into the water container portion 20 and to support the soil layer 4. Further, water evaporated from a water storage unit 23 (described later) provided in the water container unit 20 supplies appropriate moisture to the soil layer 4 through the soil layer support unit 10, or stores water from the soil layer 4 during rainy weather or watering. Excess water is discharged to the section 23, and the soil layer 4 can be kept at an appropriate humidity. In addition to this embodiment, instead of the regenerated charcoal 11, the soil layer support unit 10 may be configured using an inexpensive material such as driftwood or a demolished house.

  A water container unit 20 shown in FIG. 1 is configured by stacking a plurality of stages (two stages in this embodiment) of container units 21 as shown in FIGS. 2 and 3. As shown in FIG. 6, an air layer 24 is formed between a container unit 21A on the upper stage and a container unit 21B on the lower stage by stacking the container units 21 having the same size and shape in two stages. The container shape part 22A of the upper container unit 21A constitutes the water storage part 23. Thereby, water can be stored in the water storage unit 23, and the humidity of the soil layer 4 can be appropriately maintained. Moreover, the heat | fever withering of the plant planted in the soil layer 4 is carried out by the heat insulation effect of the air layer 24 respectively formed under the water storage part 23 and between the overflow parts 27A and 27B and the overflow part 27B. Can be prevented. Furthermore, since the container shape part 22A of the upper container unit 21A that does not directly contact the outside of the greening system 1 constitutes the water storage part 23, water leaks even if the lower container unit 21B is slightly damaged during construction or the like. Will not occur.

  The container unit 21 has at least two container-shaped portions 22 that are each connected to each other as a water container. The container unit 21 is connected to each other as shown in FIG. 2 and FIG. The shape part 22 has, for example, a truncated pyramid shape in which the cross section is a quadrangle and the cross-sectional area gradually decreases toward the lower part. By overlapping the container shape portion 22 having such a shape that gradually becomes thinner toward the lower portion, the bottom surface 26A of the container shape portion 22A of the upper container unit 21A is placed on the side wall 25B of the container shape portion 22B of the lower container unit 21B. The air layer 24 is formed between the lower container unit bottom surface 26B and the upper container unit bottom surface 26A. At the same time, the overflow portion 27B of the lower container unit 21B and the overflow of the upper container unit 21A are formed. The air layer 24 is also formed between the portion 27A.

  The container shape portion 22A of the upper container unit 21A is configured to be similar to the size of the container shape portion 22B of the lower container unit 21B and larger than the size of the container shape portion 22B. Alternatively, the air layer 24 can be formed. When the size of the upper container shape portion 22 is large, the bottom surface 26 of the container shape portion 22 is locked at a higher position than when the same size container units 21 are stacked. A larger air layer 24 can be formed when the container units 21 having portions are stacked.

  Further, the container unit 21 has a groove serving as an overflow portion 27 in which water overflows outside the adjacent container shape portion 22 or the container unit 21 at the upper center of each of the four side walls 25 forming each container shape portion 22. Have. Thereby, the water level of the water storage part 23 does not rise from the groove that becomes the overflow part 27, the water retention amount of the water storage part 23 is made constant, excess water is discharged from the water storage part 23, the water surface and the resin net 12 A space can also be formed between the two. Furthermore, if the number of the container-shaped parts 22 with respect to the installation area of the greening system 1 is increased, when the greening system 1 is installed in the inclined part, the water retention amount can be increased compared to a single container having the same depth. .

  Furthermore, the container unit 21 may be formed so that the overflow portion 27 is formed in a groove-like bridge shape and the container shape portions 22 are connected only by the overflow portion 27. You may form so that it may connect with all the upper sides. And the container unit 21 can be produced by press-molding a lightweight plastic sheet, for example, and can be produced using other well-known materials and techniques.

  Further, as shown in FIGS. 4 and 5, when the container units 21 are stacked, the positions where the container units 21 </ b> B constituting the lower stage of the water container unit 20 are adjacent to each other and the container units 21 </ b> A constituting the upper stage are adjacent to each other. By overlapping so that the positions do not align vertically, the water container portion 20 can be configured while closing the gap between the adjacent portions 28. Specifically, as illustrated in FIG. 5, a portion where the container shape portion 22A of the upper container unit 21A is connected is positioned on the adjacent portion 28B where the two container units 21B arranged in parallel are adjacent to each other. The container unit 21A is stacked. As a result, as shown in FIG. 6, the upper container unit 21A is arranged on the adjacent portion 28B between the lower container units 21B, which closes the gap between the adjacent portions 28B, and between the upper container units 21A. A lower container unit 21B is disposed under the adjacent portion 28A, and closes the gap between the adjacent portions 28A. Then, when the container unit 21 is overlapped over the entire installation surface 5 of the greening system 1 by the above-described method, as can be seen from FIG. 4, the upper container unit 21A is indicated by a solid line and the lower container unit 21B is indicated by a broken line. The gap between the container units 21 can be closed over the entire installation surface 5. Thereby, since the penetration | invasion of the root of a plant from the clearance gap between the container units 21 can be prevented, root-resistant layers, such as a root-resistant sheet | seat, can be made unnecessary. In addition, by stacking the container units 21 in this manner, the container units 21 are fixed in the horizontal direction, so that a member for fixing the container units 21 in the horizontal direction can be eliminated. In the case where the water container unit 20 is configured by stacking the container units 21 in three or more stages, at least one stage may be arranged so as to close the gap between the adjacent portions 28 of the lower stage.

  In the greening apparatus shown above, a concrete block as the earth retaining wall 2 is installed on the outer periphery of the installation surface 5 of the greening system 1, and the first container unit 21B is laid on the installation surface 5 surrounded by the concrete block. The adjacent part 28B adjacent to the container unit 21B forming the first stage of the second stage container unit 21A and the adjacent part 28A adjacent to the container unit 21A forming the second stage are not aligned vertically. The water container part 20 is constructed by laying on the resin container, and the resin net 12, the regenerated charcoal 11 and the system soil are laid in order on the water container part 20 constructed as described above, and an arbitrary plant is placed on the system soil. It can be constructed by the procedure of planting.

  According to such a greening system 1, the greening system 1 excellent in waterproofness, water retention, and heat insulation can be provided, and the number of container units 21 can be adjusted to match the shape of the installation surface 5. Easy to install. Moreover, since the same shape is used for the container unit 21, cost reduction can be achieved by mass production. Furthermore, by forming the air layer 24 by overlapping the container units 21 having the same shape, a space is also generated in a portion where the upper container unit 21 protrudes from the lower container unit 21, and the space also functions as the air layer 24. It is possible to increase the heat insulation effect.

  Below, other embodiment of the greening system concerning this invention is described. This embodiment is different from the previous embodiment in that the shape of the container shape portion 22 of the container unit 21 is different between the upper stage and the lower stage, and is the same as the previous embodiment in other points.

  As shown in FIG. 7, the present embodiment is characterized in that the shape of the container shape portion 22 is different between the upper container unit 21 </ b> A and the lower container unit 21 </ b> B constituting the water container portion 20.

  Specifically, the water container part 20 is configured by using the container unit 21 in which the container shape part 22 of the container unit 21 is higher in the lower container unit 21B than in the upper container unit 21A. So that the upper container shape portion 22A is entirely accommodated in the lower container shape portion 22B. As a result, the bottom surface 26A of the container-shaped portion 22A of the upper container unit 21A does not come into contact with the side wall 25B of the container-shaped portion 22B of the lower container unit 21B, so even if pressure is applied to the water container portion 20 from above. It is difficult for stagnation to occur in the overlapping portion, and unpleasant squeaking noises are not generated even when a person walks on the greening system 1. Moreover, the thickness which the water container part 20 occupies in the greening system 1 can be made thin.

  As mentioned above, although it described regarding embodiment of the greening system concerning this invention with reference to drawings, this invention is not limited to the said embodiment, The material of a structural member, a manufacturing method, the number of container shape parts, a container unit The arrangement and the like can be replaced with other members and manufacturing methods according to common general technical knowledge.

  For example, the shape of the container shape part 22 of the container unit 21 can take various shapes such as a truncated cone, a cylinder having a different thickness in the upper and lower steps, and a hemisphere. Further, a convex part such as a bead heading toward the inside of the container shape part 22 is produced on the side wall 25 of the container shape part 22, or a step is formed in the container shape part 22 so that the lower cross-sectional area becomes small, so The container unit 21A can be locked so that the air layer 24 can be reliably held even when pressure is applied from above. Furthermore, if the overflow part 27 used as the connection part of the container shape part 22 is formed in three-dimensional shapes, such as a groove-shaped bridge shape, the bending tolerance of the container unit 21 will improve.

  Moreover, if the wall surface extending to the soil layer 4 is integrally formed only on the outer periphery of the container unit 21 that constitutes the uppermost stage of the water container section 20, the soil can be removed only by the container unit 21 without providing the earth retaining 2 separately. Can hold.
