DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for concentrating rainwater or the like along a building or some other member on the ground below a tower supporting high-voltage electric wires, or on the ground near boundaries of various buildings. A topsoil protection panel to prevent topsoil from being scoured and run off due to a relatively large amount of rainwater drastically falling down, or other causes Things.

[0002]

2. Description of the Related Art As means for preventing such outflow of topsoil, a creeping plant protection material (Japanese Utility Model Publication No. 52-47289, Japanese Utility Model Publication No. 57-3386, etc.) formed in a mesh or lattice shape, or a box shape is known. For example, by laying a crawling plant protection board (eg, British Patent No. 1554032) on the corresponding ground. Sometimes. It is also practiced to spread "komo" under the lattice-like creeping plant protection material like the former, and to spread more hemp bags filled with soil under "komo". .

[0003]

The net-like or lattice-like creeping plant protection material and the box-shaped creeping plant protection panel described above are proposed by the present inventors, and are effective for such purposes. However, the former is not always perfect for a strong drop of rainwater from above, and the latter has sufficient topsoil protection, but it must be relatively expensive due to its structure. . Furthermore, as in the last-mentioned example, the technique of laying a hemp sack filled with soil or laying a "komo" on top of it, and laying a protective material for creeping plants thereon is cumbersome. However, there is a problem that the "komo" and the hemp bag are rotten and need to be reconstructed. An object of the present invention is to reliably protect topsoil from a strong flow of rainwater from above and from the side, and to secure it by simpler means.

[0004]

The gist of the structure of the present invention is that an upper plate portion is constituted by a plurality of unit upper plates located in the same plane with a space between them adjacent to each other,
And the lower plate portion is constituted by a plurality of unit lower plates located in the same plane below corresponding to the vertical space of the upper plate portion, and an opening penetrating the unit upper plate and the unit lower plate.
Part is formed, further in that become the upper plate unit upper and the lower plate units lower plate of the mutually adjacent when viewed from above,
A topsoil protection panel that is connected to each other with connecting arms
Te, a creeping plant as used laying on topsoil was vegetation
It is a constructed topsoil protection panel .

The unit upper plate of the upper plate and the unit lower plate of the lower plate are suitably formed in a circular shape when viewed from a plane, but a polygon such as a quadrilateral or a pentagon or any other shape is inconvenient. Not . Their respective to the unit top and unit lower plate of these
Opening sides through which the people opening the topsoil protection board when laid on vegetation ground creeping plant, leaves or stems, etc. of these plants is a plant extending outlet may pass. Of course ,
It goes without saying that it also becomes a water-permeable hole through which rainwater and the like pass.

The distance between the upper plate and the lower plate is suitably about 30 mm. Of course, the purpose is not limited to this. Examples of the connecting arm, to adopt the structure of the arm-shaped literally
You. In any case, at the position of the gap in the height direction between the adjacent unit upper plate and the unit lower plate, they are connected to each other by the connection arm while leaving a sufficient gap. The topsoil protection plate is suitably formed of a plastic material to which all components are added with a weathering agent or the like. As the plastic material, for example, polypropylene is suitable.

[0007]

According to the present invention having the above-described structure, it is possible to place a crow on the ground in the vicinity where rainwater or the like falls or falls violently.
The匐植product by Rukoto be laid on the ground that vegetation can protect the topsoil from the effluent. The topsoil protection plate is not simply arranged continuously provided in the region of the target state, and are not to be laid while vegetation creeping plant, following the contents
This is outlined below.

[0008] This leave vegetation creeping plant in the region of interest, is to continuously provided placing the topsoil protection board thereon. Enters between the upper portion and the lower plate through the leaves and stems are opening that opens a number of a unit plates and that of the creeping plants in vegetation in Target region, and further units lower plate and the unit upper plate Nobiagari the gap, Ya separating space between each unit upper plate
Each unit upper plate is extended upward through the opening formed therein . In this way, topsoil protection panels are continuously arranged in the target area
If it does, rainwater or the like that flows down or falls violently, depending on the positional relationship of the flow down or fall, hits on the unit upper plate and breaks down, and after the momentum weakens, flows down to the level of the lower plate through the separated space or opening. . At the level of the lower plate, the topsoil is exposed between each unit lower plate or inside their openings, but as described above, the momentum is weakened, and in addition, it is protected by creeping plants, A considerable amount of topsoil runoff is prevented.

[0009]

[0010]

An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the upper plate portion 2 is composed of a plurality of unit upper plates 1, 1... The lower plate portion 4 is composed of unit lower plates 3, 3,... Arranged vertically and horizontally in a plane. The unit upper plates 1, 1,... Are spaced so as to be adjacent to each other, and are positioned so that each unit lower plate 3 of the lower plate portion 4 is located at a position vertically corresponding to these separated spaces. Thus, a similar separation space is also generated between the adjacent unit lower plates 3, 3,..., And each unit upper plate 1 is positioned at a position corresponding to the space between the unit lower plates 3, 3,. Will be done. Each of the unit upper plates 1 and the unit lower plates 3 is formed in a circular shape when viewed from a plane, and has a circular opening at the center thereof, as shown in FIGS. The part 5 is formed. Further, the unit upper plate 1 and the unit lower plate 3 which are adjacent to each other are connected by a connecting arm 6. Thus, the unit upper plate 1,
.. And the unit lower plates 3, 3,.
6 make them alternately and vertically and horizontally connected as viewed from a plane. The topsoil protection plate has the above configuration, but in this example, all the above components are formed of polypropylene to which a weathering agent is added.

[0011] In this embodiment, since the above configuration is adopted, a suitable creeping plant is vegetated on the ground in the vicinity where rainwater or the like falls violently , and then laid on it to protect the topsoil from runoff. be able to. For example, it is used to protect areas such as the lower part of a tower that supports high-voltage transmission lines, in which rainwater flows down a tower or the like that constitutes the tower during rainy weather, and violently flows down, causing the topsoil 8 to flow out. Is appropriate.

In this example , the lower part of a steel tower supporting a high-voltage transmission line is applied as a target area. The lawn 7 is vegetated in advance in the target area by a general technique. Of course, if the lawn 7 is already vegetated in the target area, this operation can be omitted. FIG.
As shown in (1), after confirming that the lawn 7 has survived and is in an appropriate growing state, the topsoil protection panels are arranged vertically and horizontally in the vegetation area of the lawn 7 which is the target area. . When the topsoil protection panel is laid in the target area in this way,
As shown in FIG. 4, the leaves and stems of the turf 7 on which the vegetation is planted have openings 5, 5,... Formed between the unit lower plates 3, 3. Through upper plate 2 and lower plate 4
, And further from there through the openings 5, 5,... Formed between the unit upper plates 1, 1,... And through the unit upper plates 1, 1,.

[0013] When the topsoil protection panels are continuously arranged as described above,
Rainwater, etc., which flows down or falls violently through a frame or the like in the event of rain, first hits the unit upper plate 1, 1,. It flows down to the level of the lower plate part 4 between the upper plates 1, 1 or through the openings 5, 5,. At the level of the lower plate portion 4, the topsoil 8 is exposed between the unit lower plates 3, 3 or inside the openings 5, 5,..., But as described above, the rainwater is weakened. In addition, since they are protected by the roots of the lawn 7, their runoff of topsoil 8 is substantially prevented. On the other hand, rainwater or the like that has fallen between the unit upper plates 1, 1 or the openings 5, 5,... Collides with the leaves and stems of the lawn 7 extending here, due to the positional relationship of the falling or falling.
The force drops to the level of the lower plate portion 4 while the momentum is weakened. At this position, the topsoil 8 is exposed as described above. However, as described above, the rainwater is weakened by the leaves and stems of the lawn 7, and the roots of the lawn 7 Because of the protection, runoff of topsoil 8 is substantially prevented.
