Description

  The present invention relates to a vegetation greening device for greening an installation surface such as a wall surface of a building.

  2. Description of the Related Art Conventionally, various vegetation greening devices are known in which a plant is vegetated and fixed to an installation surface for greening a wall surface of a building. For example, in the vegetation planting apparatus 40 shown in FIGS. 6 and 7, a mesh molding mat 43 is fixed inside a thin planting tray 42 having a large number of drain holes formed on the bottom surface, and the mesh molding mat 43 has a gap. A planting tray 42 filled with soil 44 and cultivated with plants 45 is set up vertically, a water storage tank 46 is installed at the lower part thereof, and the planting tray 42 and the water storage tank 46 are connected by a water absorbing sheet 47, Water in the water storage tank 46 is supplied to the plants in the planting tray 42 by capillary action (see, for example, Patent Document 1).

Utility Model Registration No. 3064435 (FIGS. 2 and 6) Japanese Patent Laying-Open No. 2003-189734 (FIG. 2)

  However, in the first conventional vegetation planting apparatus 40 described above, the height of the water that is sucked up from the water storage tank 46 below the planting tray 42 via the water absorbing sheet 47 is limited. However, the height usually has to be about 30 centimeters or less. The water sucked up by the water absorbing sheet 47 is absorbed by the planted plant 45 and spontaneously evaporates, and in particular, at the upper part of the planting tray 42, the water is not sufficiently sucked up as described above and dries. Therefore, although the cooling effect on the planting tray 42 installation surface by the vegetated plants 45 can be expected, the cooling effect by the water supplied with a sufficient amount is not achieved.

  In the second conventional vegetation planting apparatus 50 described above, although a certain amount of water can be supplied to the water supply sheet 54, it is intensively supplied to the water supply sheet 54 near the pipe 52. It is difficult to distribute the supply water uniformly over the entire water supply sheet 54, that is, the entire apparatus 50. In addition, it is difficult to uniformly supply water to the entire apparatus 50, and supply water is insufficient in a part of the apparatus 50, while supply water is excessive in other parts of the apparatus 50, and water flows out below the apparatus 50. Therefore, it has been difficult to efficiently use the supplied water while sufficiently supplying water to the plant.

  The present invention solves the problems of the above-described conventional vegetation greening device and vegetation greening system, and by supplying sufficient water to the vegetation greening device, the cooling effect by the supply water itself can be sufficiently obtained. An object of the present invention is to provide a vegetation greening device and a vegetation greening system that can circulate the supply water and efficiently reuse the supply water to reduce costs and reduce the environmental load.

  Means taken by the present invention to solve the above problems will be described below. In the vegetation planting apparatus of the present invention, a fibrous vegetation mat that can be filled with culture soil is provided in the first layer, a water retention mat that can be infiltrated with supply water is provided in the second layer, and is vegetated on the vegetation mat. A vegetation planting device that is provided with a protective mat for suppressing the protrusion of plant roots in the third layer and greens the installation surface such as a wall surface of a building, wherein the water retention mat is disposed on the back side of the vegetation mat. An upper end portion and a lower end portion that are arranged over the entire surface and extend so as to protrude in the vertical direction of the vegetation mat are respectively provided above and below the water retaining mat ( Claim 1).

  On the top and bottom of the water retaining mat, there are provided an upper end portion and a lower end portion that protrude and extend above and below the vegetation mat. Supply water can be infiltrated into this upper end part, and supply water can be infiltrated from the upper part of a water retention mat to the lower part. Further, since the water retaining mat is disposed over the entire surface of the vegetation mat, water can be sufficiently supplied to the entire vegetation mat on which the plant is vegetated. Therefore, in addition to the cooling effect by the vegetated plant, the cooling effect on the installation surface can be further exerted by the water itself sufficiently supplied to the entire water retention mat.

  Moreover, about the surplus part of the supply water supplied to the water retention mat, it can be dripped downward from the lower end part of the water retention mat lower part, this excess water is collect | recovered and supplied again as supply water from the vegetation planting apparatus upper part Is possible. Moreover, when many above-mentioned vegetation planting apparatuses are installed up and down, this surplus water can also be utilized sequentially as supply water to another vegetation planting apparatus arranged below.

  In addition, as a vegetation greening system using a plurality of such vegetation greening devices, a vegetation greening system in which a plurality of the vegetation greening devices according to claim 1 are combined in at least the vertical direction. The upper and lower ends of the water retention mat of the vegetation greening device are accommodated at the upper and lower sides of each vegetation greening device, respectively, and a water flow portion that can supply water from a water supply source is disposed. A supply pipe connected to the water supply source is connected to at least the uppermost water passage section of the section, and excess supply water is recovered at least to the lowermost water passage section of the water tank. In addition, a vegetation greening system (Claim 2) may be provided in which a recovery pipe capable of supplying excess supply water is connected to the supply pipe.

  A plurality of the above-described vegetation planting apparatuses are combined in a plurality in the vertical direction as described above, and a water flow portion is disposed above and below each vegetation planting apparatus. Each vegetation planting device is supplied with supply water from a water supply source to at least the uppermost water passing portion, and sufficient supply water is supplied to the water retention mat via the upper end portion of the water retention mat. In addition, as described above, in the water flow portion disposed above the second-stage vegetation planting device, the lower end of the water retention mat of the uppermost vegetation planting device, and the water retention of the second-stage vegetation planting device The upper end portion of the mat is accommodated. Then, from the lower end portion of the water retention mat of the uppermost vegetation planting device, surplus water in the uppermost vegetation planting device is dropped into the second stage water passing portion, and the upper end portion of the water retention mat of the second stage vegetation greening device Is supplied as supply water. In this way, the surplus water from the upper vegetation planting device is sequentially supplied to the lower vegetation planting device as the supply water in the water passage. And the surplus water dripped at the lowermost water flow section is recovered by the recovery pipe and supplied to each vegetation planting device from the supply pipe again while supplementing water from the water supply source as necessary. .

  For example, conventionally, when water is given to plants planted in a vegetation planting device by watering with a hose, water has been spilled outside the vegetation planting system, and water has been wasted. Then, since supply water is reliably supplied to each vegetation planting apparatus by a supply pipe, each water flow part, and a collection | recovery pipe, and also surplus water is reliably reused, water resources are not wasted.

  A plurality of vegetation planting devices constituting this vegetation planting system are combined at least in the vertical direction, and may be combined in a plurality in the horizontal direction in addition to those combined in a vertical row. The supply pipe is connected so as to supply at least the uppermost water passage, and is connected only to the uppermost water passage.

Similarly, the recovery pipe is connected so as to recover surplus water from at least the lowermost water passage, and is connected only to the lowermost water passage, and other if necessary. You may provide so that it may be directly connected also to the water flow part.

  In addition, the water flow portion is formed in a bowl shape having a circular arc shape with an open top, and is provided so as to be accommodated over the entire width of the upper end portion and the lower end portion of the water retention mat of each vegetation planting device. It can also be set as the vegetation greening system (Claim 3) of Claim 2 characterized by these.

  By forming the water passing portion in a bowl shape and providing the upper end of the water retention mat so as to be accommodated over the entire width, the supply water can be infiltrated over the entire width of the upper end of the water retention mat, and directed downward. Water can be uniformly supplied to the entire water retaining mat. Moreover, it can comprise so that all the surplus water of a water retention mat | matte can be supplied to a lower vegetation planting apparatus without waste by providing a lower end part so that accommodation is possible in a water flow part over the full width. Moreover, the water flow part for supplying water to a water retention mat and collect | recovering the excessive water dripped can be comprised simply.

  Moreover, the vegetation greening system (Claim 4) according to claim 2 or 3, wherein a timer for controlling supply of supply water from the water supply source is provided.

  By providing a timer for controlling the supply of supply water, the supply water can be automatically replenished after a lapse of a certain time.

  The vegetation greening system according to any one of claims 2 to 4, wherein a sensor capable of detecting the amount or level of the recovered surplus water is disposed in the recovery pipe. 5).

  By arranging such sensors, the amount of surplus water is automatically detected and the water supplied from the water supply source is controlled to automatically control the appropriate amount of water supplied to the vegetation planting system. It becomes possible to do.

  In the vegetation greening device or the vegetation greening system of the present invention described above, water can be supplied uniformly and in a sufficient amount to the vegetation greening device, so that a sufficient cooling effect can be achieved. Moreover, water resources are not wasted by reusing excess water. In particular, in the vegetation greening system according to the third aspect of the present invention, it is possible to simply configure a water passing portion that supplies water to the water retention mat, and to reduce its manufacturing cost. Moreover, especially in the vegetation greening system of Claim 4 or Claim 5, the maintenance of a vegetation greening system can also be made simpler.

  Next, an embodiment of the vegetation planting apparatus of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the vegetation greening apparatus 20 of the present invention is installed on an installation surface A such as a wall surface of a building such as a building, and plants a plant on its main body 21. In this example, the installation surface A is a side wall surface of a building.

  The entire body 21 of the vegetation planting apparatus 20 is formed in a thin plate shape having a length of about 100 cm, a width of about 90 cm, and a thickness of about 3 cm. And many main bodies 21 of such a vegetation planting apparatus 20 are connected up and down, right and left, and the water trough 22 (the "water-flow part" of this invention) between the top and bottom of these vegetation planting apparatuses 20 and each vegetation planting apparatus 20 is connected. An example) is arranged to cover most of the installation surface A. As shown in FIG. 3, in this example, the vegetation planting system 1 is assembled by connecting five vegetation planting apparatuses 20 vertically and five horizontally.

  As shown in FIG. 3, the vegetation greening device 20 is incorporated in the vegetation greening system 1 for supplying supply water to these vegetation greening devices 20. The vegetation greening system 1 includes a water supply source 2, a supply pipe 3 connected to the water supply source 2, a recovery pipe 4, and a timer 5 attached to the water supply source 2. The recovery pipe 4 is provided with a pump 6 that pumps excess water to the supply pipe 3. The supply pipe 3 connected to the water supply source 2 is connected to a water trough 22 (excluding the bottom water trough 22z described later) disposed above and below a large number of installed vegetation planting apparatuses 20. The recovery pipe 4 is connected to a water trough 22z disposed below the lowermost vegetation planting apparatus 20. The timer 5 periodically supplies water from the water supply source 2 and performs an opening / closing operation of the water supply source 2 so that the water supply is performed at a predetermined time set according to temperature, weather, or the like. Make it.

  Next, the vegetation greening device 20 will be described in detail. As shown in FIG. 2, the main body 21 of the vegetation greening device 20 includes a vegetation mat 24, a water retention mat 26, and a protection mat 28, and the vegetation mat 24, the water retention mat 26, and the protection mat 28 from the surface. Are stacked in this order. The main body 21 of the vegetation planting apparatus 20 is formed in a thin box shape as described above.

  The vegetation mat 24 is formed into a thin sheet having a length of about 100 cm, a width of about 90 cm, and a thickness of about 2 cm. The vegetation mat 24 has, for example, a fineness of 100 to 5000 d / f and contains 40% by weight or more of the heat-fusible conjugate fiber that has been crimped. A fiber mat having a fixed density of 0.02 to 0.15 g / cm @ 3, a thickness of 1.5 to 15 cm, and a repeated compression recovery rate of 80% or more can be used. In this example, “CP mat” (trademark) manufactured by Chisso Corporation was used. “CP mat” product number RM-62 (bulk 40 cc / g, porosity 97.4%, fiber diameter 216 μ), RM-63 (bulk 20 cc / g, porosity 94.5%, fiber diameter 279 μ), RM-66 (Bulk 25 cc / g, porosity 95.6%, fiber diameter 342 μ), RM-73 (bulk 40 cc / g, porosity 97.4%, fiber diameter 394 μ), RM-74 (bulk 20 cc / g, porosity) 94.5%, fiber diameter 624 μ), and other types such as RM-66, RM-77, RM-72, and RM-101 can be used. However, other fiber mats other than these can also be used.

  The water retaining mat 26 is composed of a water absorbent fiber alone or a nonwoven fabric mixed with other fibers, for example, synthetic fibers such as polyester fibers, polyamide fibers, acrylic fibers, and polypropylene fibers. Moreover, although the thickness of the water retention mat 26 is about 2 mm in this example, it is desirable to set it as the range of 1-50 mm. If it is less than 1 mm, the water absorption ability and water retention ability to the plant are insufficient, while if it exceeds 50 mm, the thickness of the greening structure increases, which is not preferable from the viewpoint of cost. Moreover, it is desirable to contain 20 weight% or more of a water absorbing fiber in a nonwoven fabric from a viewpoint of water replenishment. This is because when the weight of the water-absorbing fiber is 20% or less, the basis weight of the entire sheet has to be increased in order not to wither the plant, and the overall thickness increases and the cost of the frame increases. is there. Therefore, it is more desirable to include 30 to 50% by weight of the water-absorbing fiber. Desirable water-absorbing fibers include, for example, cross-linked sodium acrylate fiber, synthetic fiber obtained by hydrolyzing the surface of acrylic fiber by post-processing, rayon, hydrophilized polyester, polypropylene fiber, cotton, coconut, hemp, etc. Can be used. Moreover, the water retention mat 26 should just be comprised with the material which can absorb a water | moisture content, and can also be comprised with porous bodies with water absorption, such as a foam sheet other than a nonwoven fabric, for example.

  The water retention mat 26 is provided with a horizontal length of about 90 cm, while the vertical length is slightly longer than the vertical length of the vegetation mat 24 and is provided with a length of about 110 cm. Are provided so as to protrude from the upper and lower ends of the vegetation mat 24, respectively. As shown in FIGS. 4 and 5, the upper end portion 30 of the water retention mat 26 has its tip portion downward so as to be accommodated in a water trough 22 disposed above the vegetation greening device 20 main body 21. It is made into a semicircular shape that curves toward. On the other hand, the lower end part 32 is extended downward as it is so that it may be accommodated in the water trough 22 arrange | positioned under the main body 21 of the vegetation planting apparatus 20. FIG. The water absorbed in the upper end portion 30 of the water retaining mat 26 from the upper water basin 22 infiltrates downward through the main body 27 of the water retaining mat 26, and excess water passes from the lower end portion 32 to the lower water basin 22. It is comprised so that it may be dripped.

  The protective mat 28 is made of, for example, a fine woven fabric or a non-woven fabric such as a spunbond made of polyester fiber, and prevents the roots of the plant from entering the installation surface A side, and the direction of the roots along the installation surface A. It is provided to spread. The protective mat 28 is formed into a thin sheet having a length of about 100 cm, a width of about 90 cm, and a thickness of about 1 mm.

  The vegetation greening device 20 uses the vegetation mat 24, the water retention mat 26 and the protection mat 28 in a box-shaped plastic case 34. The plastic case 34 is formed to have a size that can be accommodated by the vegetation planting apparatus 20 and includes openings 36 and 37 from which the upper end 30 and the lower end 32 of the water retention mat 26 can be projected from above and below. Yes.

  In order to plant a plant on the main body 21 of the vegetation greening device 20, first, the vegetation mat 24 is filled with cultivating culture soil, and plant seeds are planted in the vegetation mat 24. Plants are cultivated in a farm or the like with respect to the vegetation planting apparatus 20 thus formed. It is possible to prevent the plant from falling even when the roots are entangled with the vegetation mat 24 as the plant grows and the main body 21 is erected vertically. In this example, the thickness of the vegetation mat 24 is suppressed to about 2 cm as described above, the amount of culture soil to be filled can be reduced, and the weight of the entire vegetation greening system 1 can be reduced. The load on A is reduced. Therefore, even if the installation surface A cannot withstand a certain weight or more, vegetation greening can be easily realized without requiring reinforcement or the like.

  In the vegetation greening device 20 configured in this way, it is possible to vegetate various plants including plants other than lawn, moss, and ivy that have been conventionally used for wall surface greening. , Tsurmasaki, Loofah, convolvulus, chigaya, enokoro grass, etc. can also be vegetated.

  Moreover, as above-mentioned in this example, the whole vegetation planting system 1 is comprised by arrange | positioning the main body 21 of the vegetation planting apparatus 20 comprised in this way 7 vertical * 5 horizontal. And the water trough 22 is each arrange | positioned along the horizontal direction on the main body 21 upper and lower sides of each vegetation planting apparatus 20 of the vegetation planting system 1 arrange | positioned in this way. In addition, between each main body 21, the water trough 22 is shared in each main body 21 lined up and down. If a problem occurs in some vegetation greening devices 20 by configuring the vegetation greening system 1 with a large number of vegetation greening devices 20 as described above, the entire vegetation greening device 20 can be replaced by replacing only a part of the vegetation greening devices 20. Maintenance can be completed.

  A water trough 22 is provided above and below the vegetation planting apparatus 20. Each water trough 22 is formed in a trough shape with a semicircular cross-section with an open top. As described above, the water tanks 22 except for the lowermost water tank 22z are connected to the supply pipe 3, and supplied water from the water supply source 2 is supplied. Among these water troughs 22, the uppermost water trough 22 a accommodates an upper end portion 30 of a water retention mat 26 that extends from the lower vegetation planting device 20 and whose tip is curved in a semicircular shape. The water supply bath 22a is immersed in the supply water. And the front-end | tip of the lower end part 32 of this water retention mat 26 is accommodated in the 2nd stage water trough 22b arrange | positioned directly under the main body 21 of the vegetation planting apparatus 20 of the uppermost stage. And the upper end part 30 of the water retention mat 26 of the vegetation planting apparatus 20 in the second tier from the top is similarly accommodated in the water basin 22b in the second tier from the top. The main body 21 of the water tank 22 and the vegetation planting apparatus 20 is installed. And the lower end 32 of the water retention mat 26 of the lowermost vegetation planting apparatus 20 is accommodated in the lowermost water basin 22z. The lowermost water trough 22z is connected to the recovery pipe 4 as described above.

The water retention mat 26 is immersed in the supply water in each of the water basins 22a, 22b..., And the supply water infiltrates from the upper end portion 30 below the water retention mat 26. Excess supply water reaching the lower end 32 is dropped into the lower water trough 22. Thereafter, the surplus supply water is sequentially supplied to the lower water trough 22 through the water retention mat 26. Then, excess supply water that has reached the lowermost water tank 22z flows down into the recovery pipe 4. The supply water flowing down through the recovery pipe 4 and reaching the pump 6 is appropriately supplemented with the supply water from the water supply source 2 and supplied again into the supply pipe 3. In addition, the water supply source 2 is configured such that a constant amount of supply water is discharged into the supply pipe 3 every elapse of a predetermined time under the control of the timer 5, and an appropriate amount for the vegetation planting system 1 It is comprised so that supply water of this can be supplied suitably. Thus, maintainability of the vegetation greening system 1 is improved by omitting frequent supply water replenishment work.

  According to this vegetation greening device 20, the supply water is sufficiently supplied to each vegetation greening device 20 through the water supply source 2, the supply pipe 3, and each water trough 22, and the vegetation greening system 1 is further provided by the recovery pipe 4 and the pump 6. Surplus water can be circulated in As described above, since the supply water sufficiently spreads over the entire water retention mat 26 and the supply water circulates in each vegetation greening device 20, in addition to the cooling effect by the vegetated plants, the supply water itself A sufficient cooling effect on the installation surface A can be obtained.

  Further, the entire upper end 30 of the water retaining mat 26 is immersed in the supply water, and the supply water infiltrates from the entire upper end 30 toward the main body 27 of the lower water retaining mat 26, so that the entire upper end 30 is spread over. The water can be soaked uniformly and sufficiently. Therefore, the cooling effect can be further enhanced.

  In addition, since the water trough 22 is provided in a shape with an open top, in the case of the vegetation planting system 1 installed outdoors, rainwater that has fallen into the water trough 22 in the rain is used as supply water. It is possible to save costs by using natural resources.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention. For example, in the above example, the water basin 22 is assumed to have an open top, and the upper end 30 of the water retaining mat 26 is directly infiltrated into the water basin 22, but in the invention of claim 1 or claim 2, For example, the water retaining mat 26 can be supplied with water by holding the upper end and the lower end of the water retaining mat 26 in the slits of a pipe-like pipe.
