Description

  The present invention relates to a net constructed on various slopes such as a slope, and more particularly to a net that can promote natural invasion of a plant seed into a slope.

  For slopes such as slopes, various vegetation or greening is performed to protect the slope itself and to make the surrounding landscape beautiful due to the existence of this vegetation or greened slope. On the other hand, the adoption of so-called exotic species as plants for vegetation or greening has not been preferred in recent years, and it is also encouraged to do so with native species.

  When vegetation or greening is performed with native plants, it is considered unnecessary to collect seeds or grow the collected seeds into seedlings if the seeds of already grown plants can be used as they are. Patent document 1 proposes a “plant natural invasion promoting method and its device in slope greening” aiming at this.

The “Method and apparatus for promoting natural plant invasion in slope revegetation” disclosed in Patent Document 1 is described as follows: “In a steep slope, the slope easily falls down after being scattered or dropped from nearby trees, etc. It was extremely difficult to allow natural invasion at an early stage, so that this seed was reliably captured and aimed at efficient vegetation. For example, as shown in FIG. In the vegetation guidance method that creates only the growth base not included in the slope, after the growth base is established, fences are installed in one or more lines, intermittently or in a staggered pattern, or after the growth base is established An object is laid on a part or the entire surface of the creation base, or after the growth base is constructed, a fence-like object and a net-like object are installed. "
Japanese Patent Laid-Open No. 11-81327, abstract, representative diagram

However, in the technique of Patent Document 1,
・ After the growth base is constructed, fences are installed in one or more lines, or intermittently or in a staggered pattern. ・ After the growth base is constructed, a net is laid on a part or the entire surface of the foundation. After adopting one of the methods of installing fences and nets after the foundation is created, both must be “growth foundation creation”. That is, in the technique of Patent Document 1, it is indispensable to perform “growth base creation”, so it is considered that the construction may be costly and troublesome.

  In particular, in the second method described above, “the net is laid on a part or the entire surface of the base after the growth base is formed”. However, with only the “net”, the plant seeds roll or wind. It may be blown away and it may not be able to capture it sufficiently.

  Accordingly, the present inventors have made various studies on how to make a net that can simplify the cost and labor of construction and promote natural penetration of plant seeds into the slope. As a result, it has been realized that native plants have sufficient vitality to grow even on existing slopes as well as existing ones, and the present invention has been completed.

  That is, the object of the present invention is to provide a simple structure of a net that can reliably capture plant seeds and promote natural intrusion into the slope simply by laying and constructing the slope. Is to provide by.

In order to solve the above problems, the means taken by the present invention will be described with reference numerals used in the description of the best mode to be described later.
“The net 10 for promoting the natural invasion of the plant seed 20 into the slope 30,
A lifting member 12 is provided on a part of the net 10, and when the net 10 is constructed, a part of the net 10 is lifted from the slope 30 to become a lifting part 11,
The portion that becomes the valley side of the raised portion 11 is a dense portion 11a that can capture the plant seed 20, and the portion that becomes the mountain side of the raised portion 11 can enter the plant seed 20 below the net 10. A net 10 for promoting natural invasion of plant seeds, characterized in that an opening 11b is provided "
It is.

  That is, the plant seed natural invasion promoting net 10 according to the present invention (hereinafter simply referred to as the invasion promoting net 10) is knitted or woven into a planar shape as shown in FIG. Alternatively, the dense portion 11a, which will be described later, is constructed by weaving between nets with a rough mesh or connecting by using a connecting portion. As shown in FIGS. As shown in FIG. 3, by simply laying on the slope 30, a large number of openings 11b for allowing scattered plant seeds 20 to enter the lower side of the invasion promoting net 10, and these openings. A dense portion 11a that receives and captures the plant seed 20 that has entered from 11b so as not to move downward is arranged on the slope 30.

  Therefore, as shown in FIG. 3, the invasion promoting net 10 includes a plurality of rows of raised portions 11 that are continuous in the lateral direction and a connecting portion 11 c that is positioned between the raised portions 11. The raised portion 11 is lifted from the slope 30 by the lifting member 12.

  Each dense portion 11a is composed of warps (strings) and wefts (strings) constituting the invasion promoting net 10 or a fine mesh (mesh that does not catch the plant seed 20 and put it out on the opposite side), or a non-woven fabric or By forming the mat-like material, the plant seed 20 can be received. The dense portion 11a is sufficient if it can receive the plant seed 20 to the last. Of course, when forming the whole valley side of the raised portion 11 as shown by the dense portion 11a on the upper side of FIG. 3 may form the lower half of the valley side of the raised portion 11 as shown by the dense portion 11a on the lower side.

  For each opening 11b, a part of the connecting portion 11c of each dense portion 11a may be used as it is, or just a warp (string) may be used, but the invasion promoting net 10 is laid on the slope 30 When it does, it needs to open toward the mountain side. This is because, for example, the plant seed 20 which is an acorn as shown in FIG. 3 needs to roll down to the lower side of the invasion promoting net 10 through the opening 11b. Of course, if this opening 11b is greatly opened toward the mountain side, it is possible to allow the fallen leaves and earth and sand that can also be used as fertilizer of the plant seed 20 to enter the dense portion 11a and the slope 30 just before it. However, if it is too large, the plant seed 20 captured at the turning point may be exposed to the outside by the wind, so the size is preferably about 4 to 100 square centimeters.

  Now, as shown in FIGS. 1 and 2, the invasion promoting net 10 can be formed by simply laying the invasion promoting net 10 on the inclined surface 30 by lifting the raised portion 11 from the inclined surface 30. However, it is the lifting member 12 that forms the raised portion 11 on the inclined surface 30. The lifting member 12 may have various side shapes as shown in FIGS. 4B to 4D. However, the presence of the lifting member 12 does not cover the dense portion 11a and the opening 11b, and faces the mountain side. Since it is necessary, as shown in FIG. 4 (a), it must be partially arranged in a horizontal row.

  Further, since these lifting members 12 are for stopping a part of the above-described dense portion 11a at the back portion, in order to facilitate this stopping operation, as shown in FIG. It is good to have a width, for example, a width of 1 to 10 centimeters. Of course, these lifting members 12 are intended to position the dense portion 11a of the invasion promoting net 10 on the inclined surface 30 as much as possible, so as shown in FIGS. 4B to 4D. It is good that it is of a side shape.

  The lifting member 12 can be returned to the soil constituting the slope 30 after the plant seed 20 invaded is grown on the slope 30 on which the invasion promoting net 10 is constructed. Since it also becomes a fertilizer for the plant seed 20, it is preferable to form it with, for example, a wood board or a hardened waste paper.

  The invasion promoting net 10 configured as described above is deployed on the slope 30. In this case, the raised portion 11 must be formed, so that each lifting member 12 is provided on the slope 30. It is necessary to abut on the upper side, that is, each lifting member 12 is on the lower side. Of course, since this invasion promoting net 10 captures the plant seeds 20 of scattered native plants, there is no need to put fertilizer or level the slope 30.

  When this invasion promoting net 10 is laid on the slope 30, as shown in FIGS. 1 to 3, the portion of the invasion promoting net 10 held by each lifting member 12 placed on the slope 30 is as follows. A raised portion 11 is formed. In the floating portion 11, as shown in FIG. 3, the portion on the valley side becomes a dense portion 11a, and a large number of openings 11b are opened on the portion on the mountain side.

  Since each opening 11b opens toward the mountain side, as shown in FIG. 3, the plant seeds 20 scattered toward the opening 11b fall on or enter the slope 30 from each opening 11b. . Since the plant seed 20 that has fallen on the slope 30 from the opening 11b is surrounded by the slope 30 and the dense portion 11a located on the valley side of the raised portion 11, it is assumed that wind blows or water flows from the mountain side. In addition, the state of being captured by the slope 30 and the dense portion 11a is maintained. That is, the plant seed 20 that has entered the net 10 for promoting penetration from the opening 11b is held on the dense portion 11a of the floating portion 11 or the slope 30 immediately above it, and on the slope 30 captured by the dense portion 11a. It will wait for it to germinate.

  Even if this plant seed 20 falls from the opening 11b under the invasion promoting net 10 to the inner surface of the dense portion 11a and does not fall on the slope 30, it will germinate in the long term. The possible state is maintained. This is because the dense portion 11a on which the plant seed 20 is caught is literally “dense”, and thus the dense portion 11a itself has a certain amount of water retention.

  Finally, the plant seed 20 captured by the invasion promoting net 10 extends on the slope 30 and grows on the slope 30 on which the invasion promoting net 10 is constructed. .

  Therefore, the net 10 for promoting invasion according to the present invention can surely capture the plant seeds 20 only by laying and constructing on the slope 30, and can promote natural invasion into the slope 30. It is.

As described above, in the present invention,
“The net 10 for promoting the natural invasion of the plant seed 20 into the slope 30,
A lifting member 12 is provided on a part of the net 10, and when the net is constructed, a part of the net 10 is lifted from the slope 30 to become a lifting part 11.
The portion of the net 10 that becomes the valley side of the raised portion 11 is set as a dense portion 11a that can capture the plant seed 20 and the portion of the net 10 that becomes the mountain side of the raised portion 11 is directed to the dense portion 11a of the plant seed 20. Provided an opening 11b that allows the intrusion of the
In addition to the fact that the construction of the slope 30 can be easily performed, the plant seeds 20 can be reliably captured and the natural invasion of the slope 30 can be promoted. The possible invasion promoting net 10 can be provided with a simple structure.

  Next, the present invention configured as described above will be described based on the best mode shown in the drawings. In FIG. 1 to FIG. The state is shown. In these FIG. 1 to FIG. 3, a large number of raised portions 11 along the lateral direction of the slope 30 are arranged in the vertical direction of the slope 30 while being lifted from the slope 30 by the lifting member 12 below. The raised portions 11 are connected by a connecting portion 11c which is a part of the invasion promoting net 10. Here, the upward direction of the slope 30 is the “mountain side”, and the downward direction of the slope 30 is the “valley side”.

  It is sufficient that the slope 30 before the invasion promoting net 10 according to the best mode is constructed, that is, laid, has flatness enough to allow the invasion promoting net 10 to be laid, and it is necessary to bother to level the ground. There is no need to add fertilizer or improve the soil. The invasion promoting net 10 according to the present invention only captures the plant seeds 20 that have scattered or fallen from the surroundings of the slope 30, and the germination and growth of the captured plant seeds 20 are related to the plant. This is because the natural vitality inherent to the seed 20 is used as it is.

  As shown in FIG. 4, the invasion promoting net 10 according to the best mode has a net body 10a and a lifting member 12 attached to a part of the net body 10a. When the invasion promoting net 10 is constructed by the raising member 12, a part of the net body 10 a is lifted from the inclined surface 30 and becomes a raised portion 11.

  The net body 10a can be configured in various ways and by various methods, and is most easily formed by knitting in a net shape with synthetic fiber yarns (strings) or natural fiber yarns (strings). . Further, the net main body 10a may be configured by forming the dense portion 11a described below in a mat shape and connecting the dense portions 11a to each other with a string-like object or an on-net object serving as a connecting portion 11c described later.

  In configuring the above net body 10a, it is necessary to make it possible to form the raised portion 11 by the lifting member 12, but the portion that becomes the valley side of this raised portion 11 is also shown in FIG. The dense portion 11a capable of capturing the plant seed 20 and the portion on the mountain side of the floating portion 11 need to be an opening 11b that allows the plant seed 20 to enter the net body 10a. In other words, the above-described lifting member 12 may be provided in a portion that becomes the dense portion 11a of the net body 10a.

  As described above, the dense portion 11a can be configured as a net having a mesh that can capture the plant seeds 20, or can be configured as a mat. In the best mode, the corresponding portion of the net body 10a is used. Made of finely woven. Since it is sufficient for the dense portion 11a to be able to receive the plant seed 20, as shown by the dense portion 11a on the upper side of FIG. 3, the entire valley side of the raised portion 11 is formed as the dense portion 11a. In this case, of course, as shown by the dense portion 11a on the lower side in FIG. 3, only the lower half on the valley side of the raised portion 11 may be formed as the dense portion 11a.

  On the contrary, the opening 11b of the best mode is formed by making the woven portion of the corresponding part of the net body 10a rougher than the dense part 11a shown in FIG. This is because it is sufficient for these openings 11b to introduce the plant seeds 20 rolling from the mountain side of the slope 30 or scattered from the surroundings under the net body 10a constituting the invasion promoting net 10.

  As shown in FIGS. 1 and 3, the openings 11b and the dense portion 11a are connected by a connecting portion 11c so as to have an area as shown in FIG. In other words, the net body 10a is formed by alternately weaving a plurality of dense portions 11a, openings 11b (portions), and connecting portions 11c.

  The raised portion 11 having the opening 11b and the dense portion 11a is formed of a material different from the net body 10a, and the raised portion 11 is formed of a material different from that of the net body 10a. The above-mentioned “base material” may be integrated on the unbroken net main body 10a by attaching a lifting member 12 described later on a “base material” that is long in the direction. .

  Now, the lifting member 12 of the best mode provided on the lower side of the net body 10a described above has a triangular shape as shown in FIGS. 1 to 3 and FIG. 4B. However, as shown in FIGS. 4 (c) and 4 (d), the lifting member 12 may be implemented by making its side shape a half moon or a quadrangle. is there. Of course, the lifting member 12 lifts a part of the net body 10a to form the lifting part 11, and at least a part of the dense part 11a and the opening 11b must be directed to the mountain side. As shown in (a) of FIG. 4, it must be partially present in the lateral direction of the net body 10 a.

  The invasion promoting net 10 may be constructed by simply deploying the net 10 on the slope 30. Therefore, the lifting member 12 is attached in advance to a portion to be the dense portion 11a of the net body 10a. As the attachment method, it is most convenient to fix the dense portion 11a to the back of each lifting member 12 with staples, but it may be implemented as shown in FIG.

  In FIG. 5A, a base material is attached on the net body 10a, a part of the attachment material 12a as a surface fastener is fixed on the base material, and the other part of the attachment material 12a is lifted up. It is fixed below the member 12. Before the construction of the invasion promoting net 10, the lifting member 12 is placed on the net body 10a as shown on the left side of FIGS. 5A and 5B. Immediately before, as shown on the right side of FIGS. 5A and 5B, it wakes up. When the lifting member 12 is raised, the attachment member 12a is folded in two and comes into close contact with each other, so that the lifting member 12 stands against the net body 10a.

  In the case as described above, the invasion promoting net 10 before construction can be wound without waste, and storage and transportation become easy. At the time of construction, each lifting member 12 is easily required. It can be made.

  In FIG. 5C, the standing member 12b is attached to an appropriate position of the lifting member 12, and when the invasion promoting net 10 is wound, the standing member 12b is removed and the intrusion promoting member is removed. When constructing the net 10, the raised member 12 is fixed by the standing material 12b. If the standing member 12b is an elastic string that expands and contracts, each lifting member 12 automatically rises when the invasion promoting net 10 is unwound, so that the above operation is further simplified. It can be.

The present invention can also be implemented as follows.
