Description

  The present invention relates to an aquatic plant planting apparatus that can plant aquatic plants in the watersides of natural waterways and artificial waterways, and contributes to water quality purification of waterways.

  In order to plant aquatic plants at the bottom of the waterway, it is necessary to prevent the outflow of soil material due to water flow and to firmly root the plant. For this purpose, a planting structure for aquatic plants disclosed in JP-A-8-84532 has been proposed. The planting structure uses a cylindrical planting pot having a vertically long cylindrical shape whose upper and lower ends are open. The tubular planting pot is filled with a soil material to plant aquatic plants, and this is the bottom of a water channel. In the predetermined position, the lower part is installed in an upright state. Since the cylindrical planting pot has a vertically long cylindrical shape, it is necessary to support it so that it does not fall down through stones when it is installed at the bottom of the water channel. Therefore, a large number of planting pots are installed. When doing so, there were problems such as complicated work.

  In order to solve such a problem, an aquatic planting structure disclosed in JP-A-10-98962 has been proposed. As shown in FIGS. 29-30, this planting structure is a synthetic resin in which a vertically long pot for planting a made of synthetic resin with upper and lower ends opened is superposed vertically at a predetermined position on the bottom of a water channel. It was fixed to the resin-made installation mats b and c in a standing state via a stainless steel fixing device d having a long bowl shape. The upper installation mat c is provided with a plurality of pot fixing holes e penetrating vertically, and the lower portion f of the planting pot a is inserted into the pot fixing hole e, The end face g is placed on the lower installation mat c, and the planting pot a is accommodated between a plurality of bars h, h extending upward in the hook-shaped fixing device d. It was made to.

When such a planting structure is used, the planting pot can be fixed at a predetermined position on the bottom of the water channel, and there is an advantage that the soil material j filled in the planting pot a can be prevented from flowing out by the water flow. In order to fix the planting pot a at a predetermined position at the bottom of the water channel, not only the installation mats b and c having the above-described configuration through which the pot fixing hole e is penetrated but also a special fixing device d needs to be used. In addition, there is a problem in that the work for fixing the position of the pot for planting takes time and increases the construction cost. Further, since the pot for planting is fixed by the pot fixing hole e of the installation mat b, the pot for planting cannot be installed in a free arrangement. In addition, since the planting pot a and the installation mats b and c are made of synthetic resin, and the fixing device d is made of stainless steel, the aquatic plant k is rooted at the bottom of the water channel. Since the planting pot, the installation mat, and the fixing device remain without being disassembled afterwards, there is a trouble that these must be collected in order to prevent the waterway landscape from being damaged.
JP-A-8-84532 (page 2-3, FIG. 1) JP-A-10-98962 (page 2-3, FIG. 1, FIG. 3, FIG. 5, FIG. 6)

  The present invention was developed in view of such conventional problems, and in a state where a cylindrical pot capable of reliably planting aquatic plants by preventing the outflow of soil material is positioned at the bottom of the water channel as desired. An object of the present invention is to provide an aquatic plant planting device that can be fixed easily and reliably. Further, an object of the present invention is to provide an aquatic plant planting apparatus that does not require the effort of collecting a cylindrical pot or the like after the aquatic plant has taken root.

In order to solve the above problems, the present invention employs the following means.
That is, the aquatic plant planting apparatus according to the present invention has a vertically long cylindrical shape with open upper and lower ends, and a cylindrical pot capable of planting aquatic plants with soil material accommodated therein, and two adjacent cylindrical shapes. A pair of holding pieces that are inserted into both cylindrical pots and hold opposite side walls of the cylindrical pots. It is characterized by having the following.

  A more specific aspect of the aquatic plant planting apparatus according to the present invention is a vertically long cylindrical shape with the upper and lower ends opened, and can plant aquatic plants with soil material housed in the lower part inside, and It consists of a cylindrical pot that supports aquatic plants on the inner surface of the upper part inside, and a connecting tool that connects the lower end sides and / or the upper end sides of two adjacent cylindrical pots. The cylindrical pot is inserted into the cylindrical pot so as to hold the opposing side wall portions of the cylindrical pot, and the cylindrical pot is made of biodegradable aggregate formed by crushing tuff. And a porous block cured in a porous shape via a binder, and the connector is entirely formed of a biodegradable resin.

  Another aspect of the aquatic plant planting apparatus according to the present invention is a vertically long cylindrical shape with the upper and lower ends open, and a cylindrical pot that can plant aquatic plants with soil material housed inside, and two adjacent plants. The cylindrical pot includes a connecting tool for connecting the lower end sides and / or the upper end sides of the cylindrical pot, and a spacing holding piece interposed between adjacent cylindrical pots, and the connecting tool is inserted into both cylindrical pots. It is characterized in that the side wall portions facing each other of the cylindrical pot are clamped with the spacing holding piece interposed therebetween.

  A more specific aspect of the aquatic plant planting apparatus according to the present invention is a vertically long cylindrical shape with the upper and lower ends opened, and can plant aquatic plants with soil material housed in the lower part inside, and A cylindrical pot that supports aquatic plants on the inner surface of the upper part inside, a connector that connects the lower end sides and / or the upper end sides of two adjacent cylindrical pots, and an intervening cylindrical pot The connecting member is inserted into both cylindrical pots, and is configured to sandwich the opposing side wall portions of the cylindrical pots with the spacing holding pieces interposed therebetween, and The cylindrical pot is a porous block in which aggregate formed by crushing tuff is hardened in a porous shape via a biodegradable binder, and the connector is entirely made of biodegradable resin. Characterized by being formed A.

  In each of the aquatic plant planting apparatuses, the cylindrical pot may be formed in a vertically long cylindrical shape, and a circular concave surface may be provided on the outer surface of which the circular peripheral surface portion of the adjacent cylindrical pot fits.

  In each of the aquatic plant planting devices, the connecting tool is such that the holding pieces inserted into the adjacent cylindrical pots on both sides of the substrate protrude in an opposing state, and the holding pieces are adjacent cylinders. It is good to comprise so that the side wall parts which a shape pot opposes may be held. In this case, it is preferable that the leading ends of the both holding pieces are bent obliquely in the opposite direction, and an enlarged guide portion is formed between both bent portions.

The present invention has the following excellent effects.
(1) The aquatic plant planting apparatus according to the present invention has a vertically long cylindrical shape with open upper and lower ends, and two adjacent cylindrical pots capable of planting aquatic plants with soil material accommodated therein. Since the cylindrical pot is composed of a connecting tool for connecting the lower end sides and / or the upper end sides of each cylindrical pot, the cylindrical pot is simply connected by inserting a holding piece from the lower side or the upper side of the cylindrical pot. The pots can be easily connected. This also keeps the positional relationship between the cylindrical pots correct and allows the whole to be connected in a stable state, preventing the cylindrical pots from being displaced, and the cylindrical pot rows are fence-like and effective as earth retaining. Can function.
However, since the connector has a holding piece that is inserted into the cylindrical pot and holds the side walls facing each other, the cylindrical pot is connected in a linear state or various curved states. Even if it exists, compared with the conventional apparatus using the mat for installation which has a pot fixing hole, considering the design of the prosperous state of an aquatic plant, a continuous arrangement with a high form freedom can be performed easily.
Thereby, it becomes possible to grow aquatic plants substantially in accordance with the set configuration of the cylindrical pots, and to improve the landscape of the water channel.

  (2) The cylindrical pot has a vertically long cylindrical shape with the upper and lower ends open, and aquatic plants can be planted with the soil material housed inside. In addition to preventing water from being washed away, even at low water levels, water can be supplied to the soil material from the open bottom of the cylindrical pot, promoting the growth of aquatic plants, and rooting the soil at the bottom of the canal be able to.

(3) Especially when the aggregate formed by crushing the tuff is hardened into a porous cylinder via a biodegradable binder, and the connector is made of a biodegradable resin. In addition, since the binder and connector of the cylindrical pot are biodegraded, it is not necessary to remove them after the aqueous plant has taken root, and a biodegradable resin dissolved in water can be used as a nutrient for the aquatic plant. In addition, there is an advantage that the aggregate constituting the cylindrical pot can be made into a soil having excellent fertilizer and water retention.
In addition, since the cylindrical pot is made of tuff aggregate, the good water retention promotes the growth of algae and microorganisms on the surface and inside thereof, and water purification by microorganisms can be achieved. In particular, when moths and moths are used as water-based plants, they grow by absorbing nitrogen and phosphorus, which are sources of contamination in the water. Nitrogen and phosphorus can be absorbed well, and water purification can be achieved efficiently.

  (4) When the lower part inside the cylindrical pot is used as a soil material container, and the inner surface of the upper part inside the cylindrical pot is used as a plant support part that supports aquatic plants, the aquatic plants take root. In the meantime, it is possible to more effectively prevent the aquatic plants from falling down due to the water flow.

  (5) In the case where a spacing piece is interposed between adjacent cylindrical pots, it is preferable because the continuous form of the cylindrical pots can be changed.

  1-2, the aquatic plant planting apparatus 1 which concerns on this invention is the coupler 3 which connects the cylindrical pot 2 which plants an aquatic plant, and the lower end side of two adjacent cylindrical pots 2 and 2 mutually. It consists of and.

  The cylindrical pot 2 has a vertically long cylindrical shape with the upper and lower ends open as shown in FIGS. 1 and 2, and is formed as a porous block having tuff as aggregate 5 as shown in FIG. 3. More specifically, the cylindrical pot 2 is obtained by curing a gravel-like aggregate 5 formed by crushing tuff into a porous cylindrical shape using, for example, a biodegradable resin made of corn as a binder 6. For example, the inner diameter is about 90 mm, the wall thickness is about 30 mm, and the height is about 300 mm. In this embodiment, as shown in FIG. 4, the lower 1/4 to 部分 length of the cylindrical pot 2 is a soil material (natural or artificial soil material for planting) 7. While being set as the accommodating part 9, the upper part is made into the plant support part 13 which supports the aquatic plant 11 by the inner surface 10 (supports a stem, a leaf, etc.). The binder is biodegraded in about 2 to 3 years.

  Further, the connector 3 is a hard one integrally formed of, for example, a biodegradable resin made from corn. As shown in FIG. 1, the connector 3 is adjacent to both ends in the longitudinal direction of a substrate 14 having a rectangular plate shape. The holding pieces 15, 15 inserted into the matching cylindrical pots 2, 2 have a clip-like shape protruding in an opposing state, and the front sides of the holding pieces 15, 15 are bent obliquely in the opposite direction, An enlarged guide portion 17 is formed between the portions 16 and 16. As an example of the dimensions of each part of the connector 3, the substrate 14 has a short side of about 40 mm and a long side of about 70 mm, the holding piece 15 has a protruding length of about 75 mm, and the bent portion 16 has a vertical length of about 70 mm. The total wall thickness is set to about 5 mm. The connector 3 having such a structure is biodegraded in about 2 to 3 years.

In this connected state, as shown in FIG. 2, the lower ends 21 and 21 of both cylindrical pots 2 and 2 are placed on the substrate 14 placed on the soil and gravel of the water channel bottom 22, and FIG. As shown in FIG. 2, the both side walls 19 and 19 are elastic between the both holding pieces 15 and 15 in a state where both sides 18 and 18 of the holding pieces 15 and 15 are in contact with or substantially in contact with the inner surface 10 of the cylindrical pot 2. It is held in the middle. Since the enlarged guide portions 17 are formed by bending the front end sides of the both holding pieces 15, 15 constituting the connecting tool 3 obliquely in the opposite direction, the both side wall portions 19, 19 are connected to the both holding pieces 15, 15. Easy to insert between them.

In this connected state, the substrate 14 of the connector 3 is placed on the upper ends 23 and 23 of the cylindrical pots 2 and 2 and both sides 18 and 18 of both holding pieces 15 and 15 as shown in FIG. Both side wall portions 19 and 19 are held between the holding pieces 15 and 15 in a state of being in contact with or substantially in contact with the inner surface 10 of the cylindrical pot 2. Thus, when connecting the upper end side of two adjacent cylindrical pots 2 and 2, after connecting a cylindrical pot, both holding pieces 15 and 15 of the said coupling tool 3 are put in the cylindrical pot 2. As shown in FIG. Since it is only necessary to insert from the upper end side, the construction efficiency can be improved.

  FIG. 10 shows a state in which the lower end side and the upper end side of two adjacent cylindrical pots 2 and 2 are connected by the connecting tool 3 in the linear parallel state. When connecting the lower end sides and the upper end sides of the cylindrical pots, the upper end sides are connected to each other with several cylindrical pots in between, for example, every three pots. There is also. If the upper and lower connections are made in this way, the connection of the cylindrical pots becomes more stable, and the functionality as a soil retaining can be improved.

  FIG. 11 shows a state in which the cylindrical pot 2 is in contact with the outer surfaces 20 and 20 of the side wall portions 19 and 19 and arranged in a curved shape in plan view. The cylindrical pots 2, 2 are connected to each other at the lower end side and the upper end side by the connecting tool 3. In this case, any one of the upper and lower connectors 3 and 3 may be omitted.

  FIG. 12 shows a case where the cylindrical pots 2 are juxtaposed in a straight state in a plan view in a branched state with respect to one of the cylindrical pots 2a. The lower end sides and the upper end sides of two adjacent cylindrical pots 2 and 2 are connected by the connecting members 3 and 3. In this case, any one of the upper and lower connectors 3 and 3 may be omitted. When juxtaposed in a branched state in this way, the juxtaposed state of the cylindrical pots 2 may be set to a curved state as shown in FIGS.

  FIG. 4 shows the soil material 7 filled in the accommodating portion (a portion having a length of about 1/3 of about 1/3 of the lower side of the cylindrical pot 2) 9 of the cylindrical pot 2 thus connected. It shows a state where seedlings of aquatic plants 11 such as cocoons and cocoons are planted. The soil material 7 is a natural or artificial soil material for planting, and the lower portion of the cylindrical pot 2 having a length of about 1/3 of about 10 cm is embedded in the soil 24 at the bottom 22 of the water channel. ing.

  FIG. 15 shows a state in which planting portions 27 are formed on both sides of the water channel 26 using the aquatic plant planting apparatus 1 according to the present invention. The water channel 26 is formed, for example, as an artificial water channel formed on the upper surface of a culvert 30 constructed by connecting box culverts 29, and is continuous with both side portions (watersides) of the water channel 26 in its length direction. The planting parts 27, 27 are formed.

  In order to form the planting portion 27, as shown in FIGS. 4 to 6, the cylindrical pot 2 having the above-described configuration is brought into contact with the outer surfaces 20, 20 of the side wall portions 19, 19 so as to stand upright In parallel with each other, the lower ends of two adjacent cylindrical pots 2 are connected to each other by the connector 3 as shown in FIG. 7 is carried out. Thereafter, as shown in FIGS. 15 and 4, seedlings of aquatic plants 11 as cocoons and straws are put into the soil material 7 and the roots thereof are planted. At this time, the upper end of the aquatic plant is made to protrude from the upper end of the cylindrical pot.

  As a result of connecting the cylindrical pots with the connector 3 as described above, the positions of the cylindrical pots are determined, so that the parallel installation of the cylindrical pots can be performed accurately. And since the cylindrical pot row | line | column 28 formed by this connection exists in the stable state as a whole, until the aquatic plant takes root, the standing position of each cylindrical pot 2 does not shift | deviate with a water flow, This arrangement form (arrangement design) can be maintained, and aquatic plants can be grown according to the arrangement design of the cylindrical pot. In addition, since the entire cylindrical pot 2 is integrated via the connector 3, the cylindrical pot row 28 can function effectively as a retaining fence, and between the cylindrical pot rows 29, 29. A running water section is secured.

  In addition, since the connection tool 3 which connected the lower end side of a cylindrical pot is embed | buried under a water channel bottom part and cannot be visually observed, the scenery of a water channel is not impaired.

  And the length part 31 about 10 cm above the cylindrical pots 2 arranged side by side protrudes from the water surface 32, and as shown in FIG. However, since the cylindrical pot 2 is formed as a porous block, water penetrating the side wall portion 19 of the cylindrical pot 2 is supplied to the soil material 7 as shown by arrows in FIG. , Supplied to the aquatic plant 11. Moreover, since the lower end 33 of the cylindrical pot 2 is open, water is supplied to the soil material through the lower end 33 and supplied to the aquatic plants as shown by arrows in FIG. 4 even at a low water level. Will be.

  The aquatic plant 11 planted in this way is prevented from flowing out of the soil material 7 by the cylindrical pot 2, and its stem 12 and leaves are supported by the inner surface 10 of the plant support portion 13. Until the aquatic plant 11 takes root, it is safely protected by the cylindrical pot 2 so that it is not washed away by water flow. FIG. 16 shows a state in which the aquatic plant 11 planted on the soil material 7 has rooted and has grown buds, and the roots of the aquatic plant are stretched from the lower end of the cylindrical pot 2 into the soil at the bottom of the water channel.

  In the present embodiment, the cylindrical pot 2 and the connector 3 only need to maintain the form until the culm or culm is rooted in the soil at the bottom of the water channel. The connector 3 is formed by using a biodegradable resin as described above, and the biodegradable resin has a vigorous growth of wrinkles and wrinkles, and has a vigorous stock split. After years, the biodegradable resin is biodegraded, and the shapes of the cylindrical pot 2 and the connector 3 are destroyed.

  Since the biodegradable resin is formed from corn as a raw material as described above, the biodegraded resin is a safe nutrient used for plant growth. Also, the gravel-like aggregate 5 constituting the cylindrical pot 2 is weakly acidic, porous, and excellent in fertilizer and water retention power, so that it becomes a good soil.

  FIG. 17 shows a state in which ridges and ridges have grown on both sides of the water channel. The prosperous state substantially matches the pre-designed arrangement state of the cylindrical pot 2. In the same figure, the state which the form of the said cylindrical pot 2 and the said coupling tool 3 collapse | crumbled by the biodegradation of the said biodegradable resin is shown. The moths and moths grow by absorbing nitrogen and phosphorus, which are sources of pollution in the water. Periodically mowing them to activate aquatic plants and absorb nitrogen and phosphorus well. Can do. The cylindrical pot is made of tuff gravel-like aggregate 5 and, because of its good water retention, the growth of algae and microorganisms on its surface and inside is promoted, and organic substances are decomposed by microorganisms. Water purification can be achieved.

  FIG. 18 shows another embodiment in which planting portions 27 and 27 are formed in the water channel 26 using the aquatic plant planting apparatus 1 according to the present invention. The water channel 26 is formed as a natural or artificial water channel, and the planting portion 27 is formed on both sides of the water channel 26 so as to be continuous in the length direction. The planting portion 27 has the cylindrical pot 2 having the above-described configuration in contact with the outer surfaces 20 and 20 of the side wall portions 19 and 19 as described above, and is arranged in a standing state, and two adjacent pots As shown in FIG. 2, the lower ends of the cylindrical pots 2 are connected to each other by the connector 3, and then the storage portion of each cylindrical pot 2 (about 1/3 of the lower side of the cylindrical pot 2 The portion of about 20 cm length) 9 is filled with soil material 7.

  Each cylindrical pot 2 is in a state of being stabbed into the lower portion of the inclined side surface portion 35 of the water channel, and the lower end side portion 36 of the cylindrical pot 2 is buried in the soil, and is formed by the connection. The shaped pot row 28 also functions as a retaining fence. In FIG. 18, the cylindrical pot 2 is submerged, and reference numeral 38 is a crushed stone layer.
