Abstract

PROBLEM TO BE SOLVED: To provide the planter capable of planting and raising a plant on a road side surface or a dike slope comprising pitched stones or concrete blocks or in an aqueous muddy field. SOLUTION: This net planter with an anchor comprises a freely elastic and deformable cylindrical net 1 and an anchor cord 2 or anchor rod whose one end is attached to the net. When the net planter is used on a waterside, the anchor cord 2 is bound to a pile 7, to which a brush 9 capable of being opened in an umbrella-like shape is coaxialy attached.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planter used for vegetation on a shoulder or embankment slope or waterside made of masonry or concrete blocks.

[0002]

2. Description of the Related Art To protect the natural environment, vegetation must be provided on both slopes or watersides of roads or embankments.
For this purpose, sandbags or pots containing seedlings and soil have conventionally been buried in mudlands on both sides of roads or embankments or on watersides.

[0003]

In order to apply vegetation on both sides of a masonry or concrete block road or revetment embankment, sandbags or pots are buried in the ground between stones and stones or in the gap between blocks. However, it is difficult to embed the sandbag or pot because the gap is narrow. In addition, the mud at the waterside has a problem in that the seedlings planted at an angle rise and do not take root.

An object of the present invention is to solve these problems, and an object of the present invention is to easily vegetate even a road or a dike with a bare ground made of masonry or concrete blocks. An object of the present invention is to provide a planter that can be applied and can surely grow a plant plant.

[0005]

In order to achieve the above-mentioned object, a means adopted by the present invention is that a planter is constituted by a tubular cord net which can be expanded and contracted, and a rod-shaped anchor or an anchor is attached to the net. To have a string for After the plant has taken root, the planter is no longer used. Therefore, it is desirable that the net and the anchor string be made of natural fibers that degrade naturally or made of a biodegradable synthetic resin.

[0006] Anchor strings provided on the net are used to bind to the stones or the like existing on the site and use the stones or the like as an anchor. Further, the anchor string may be connected to a member made of a material whose volume is expanded by a brush or a water absorbing agent which opens and closes in an umbrella shape to form an anchor.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A planter according to the present invention will be described based on an embodiment shown in the drawings. As shown in FIG. 1, the planter includes a tubular net 1 made of a string of natural fibers or biodegradable synthetic fibers, and one or more anchor strings 2 extending from the net. The upper and lower lengths of the net 1 are very large compared to the inner diameter, and the upper end of the anchor cord 2 is connected to the lower edge of the net 1. Since the net 1 can be freely expanded and contracted, its shape changes depending on the shape of the artificial soil 3 to be put inside. The artificial soil 3 is a woven or non-woven fabric made of natural fibers or biodegradable synthetic fibers. FIG. 2 shows a bottle shape, a long cylinder shape,
The artificial soil 3 having a spherical shape and a short columnar shape is packed in a net 1. Instead of artificial soil, a general soil conditioner may be packed in the net 1 and used.

As shown in FIG. 2, the seedlings are wrapped in artificial soil 3 so that the seedlings to be planted become the core. For dry land,
A water retention agent is contained in the artificial soil 3. An anchor string 2 hanging from the net 1 is connected to a stone 4 or the like at the site. In this state, as shown in FIG. 3, the concrete block 5 is embedded in the underground hole 6 between the concrete blocks 5 on the road surface. Even if the width between adjacent concrete blocks is somewhat narrow, the net 1 and the artificial soil 3 therein can be easily embedded because the net 1 and the artificial soil 3 therein can be deformed. Even if the slope of the road shoulder is steep, the net 1 is fixed by the anchor cord 2
Therefore, there is no danger that the net 1 will fall off the road shoulder along with the seedlings. Although not shown, when the reinforcing bar is exposed in a ring shape from the block, the anchor string may be tied to the reinforcing bar instead of to the stone. By the time the net 1 and the anchor string 2 are degraded by the microorganisms in the ground, the seedlings are firmly rooted in the ground.

[0009]

Next, a description will be given of an embodiment which is suitable for muddy water. The net 1 and the anchor string 2 in FIG. 4 are the same as those in the above embodiment. The tip of the anchor string 2 is passed through a string hole 8 of a pile 7 made of a biodegradable synthetic resin, and
Is tied to A brush 9 also made of a biodegradable synthetic resin protrudes coaxially from the tip of the pile. Since this cylindrical brush 9 opens and closes like an umbrella, when it is covered with a water-soluble paper cap 10, it closes like an umbrella and becomes thin. When the cap 10 melts in the mud, the brush 9 opens again like an umbrella. The artificial soil 3 in the net 1 is filled with aquatic plant seeds or seedlings.

As shown in FIG. 5, the pile 7 is driven down to a relatively dense mud layer indicated by dense hatching in the diagram of the muddy water below the water surface. At this time, the net 1 connected to the pile 7 via the anchor string 2 is embedded in a relatively low-density mud layer indicated by rough hatching in the figure above the high-density mud layer. When the brush 9 below the pile 7 cannot be covered with the cap, the brush 9 is gradually opened like an umbrella against the force of pulling the planter upward, and when the cap is covered, the cap 10 dissolves in water and disassembles. Open as an umbrella. Since the opened brush 9 prevents the pile 7 from coming off the mud layer, there is no possibility that the net 1 is washed away, and the aquatic plants can be firmly rooted in the muddy ground.

[0011] As shown in FIG.
It is also possible to attach an anchor rod 11 that opens in an umbrella shape and drive the anchor rod 11 into the ground of a gap such as a rock to perform vegetation. This anchor rod is also preferably made of a biodegradable wooden or biodegradable synthetic resin, but may be made of a non-biodegradable synthetic resin or a metal if there is little hindrance.

[0012]

As described above, the planter of the present invention comprises:
Since it is made of a deformable net, unlike conventional sandbags or pots, it is possible to plant and grow plants on masonry or concrete block-made roads or in narrow gaps on embankment slopes. In addition, since the planter of the present invention has an anchor string or an anchor rod, the anchor string is tied to a stone or the like, or by inserting the anchor rod into the ground, a steep slope or the like which is impossible with the conventional one. Plants can be firmly rooted on land that is easily washed away by water.

[0013] Furthermore, since the brush tied with the anchor string does not flow away even when buried in underwater muddy ground,
Aquatic plants can be planted and raised on the waterside. Therefore, the planter of the present invention has an excellent effect of helping to restore the natural environment destroyed by masonry or concrete block construction on a wide range of roads or embankments including national roads and prefectural roads.
