DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope drainage member for preventing runoff due to rainwater or the like on a slope, and more particularly to a drainage member suitable for application while performing vegetation on the slope. It relates to attached vegetation zone.

[0002]

2. Description of the Related Art A newly formed land or a slope formed on the side of a newly passed road must be protected by some method or the surface soil will flow due to rain or the like ( The sloping itself collapses. For this reason, the vegetation method of actively growing and protecting plants on the slope has been adopted.However, this vegetation method is very important until the growth of the plants is completed. You must try to prevent the runoff.

[0003] For this reason, for example, Japanese Utility Model Laid-Open No. 53-37205.
In the official gazette, "Drainage channel for draining only rainwater etc." will be positively formed on the slope "Reinforced buried body of earth structure"
Has been proposed. As shown in FIG. 11, the reinforced buried body is attached to the vegetation zone 100 with a synthetic resin mesh drainage member in a certain direction and at appropriate intervals with respect to the thread 1 of the mesh vegetation zone 100 with mesh drainage member. Each of the strips 2 is arranged integrally with the vegetation zone 100 with the drainage member, and a plurality of strips 3... Along the longitudinal direction of each strip 2 are arranged on the strip 2 at intervals. Are fixed, and the upper surface of each of the strips 3 is covered with a nonwoven fabric, a net-like sheet, or another water-permeable sheet 4 so that each strip 3
... formed with drainage 5 in between ", but it is considered that protection of the side of the slope not covered by the water-permeable sheet 4, that is, prevention of runoff, is not possible.

On the other hand, for example, Japanese Utility Model Laid-Open No. 59-140
No. 344 proposes a "planting mat".
As shown in FIG. 12, this grass planting mat is provided with a water-permeable mat portion having a constant thickness that allows water to flow freely in a thickness direction and a planar direction with a synthetic resin material, and is provided on the surface of the water-permeable mat portion. A perforated plate made of a flexible synthetic resin plate is integrally fixed, and a soil receiving rib continuous in the width direction on the surface opposite to the water-permeable mat portion is provided on the perforated plate at regular intervals. And a large number of through holes are provided at the base of the rear surface of the earth receiving rib. "It is considered that the slope of the slope on which the rib is constructed can be prevented from flowing out.

However, Japanese Utility Model Application Laid-Open No.
In the grass plant mat disclosed in Japanese Patent Publication No. 44-44, a vegetation base material including plant seeds is sprayed and used in the earth receiving ribs 4 which protrude in the lateral direction of the slope. The surface of the vegetation base material is only protected by the net 6, and is hardly useful for preventing the vegetation base material itself from running off against rainwater flowing on the surface.

For this reason, the applicant has filed Japanese Utility Model Application No. 60-156.
In the '268 application, a drainage mesh has been proposed. As shown in FIG. 13, the drainage net is formed by attaching drainage material 2 to the net body 1 in a streak shape. This is advantageous because it can be drained downward.

However, in such a drainage mesh, a part of the drainage received by the drainage material 2 may flow again on the slope while flowing through the drainage material 2. Unfortunately, it was not unfortunate that all of the wastewater was drained below the slope by the drainage material 2. This was not a problem, especially in the case of low rainfall, but it was a problem in the case of sediment swings, which tended to run off.

The present inventors have conducted various studies on how to overcome the above-mentioned disadvantages of the prior art, and as a result, completed the present invention.

[0009]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned situation, and a problem to be solved is to prevent the topsoil from flowing out simultaneously with the vegetation on the slope. Draining is also effective.

An object of the present invention is to allow drainage such as rainwater flowing on a slope to flow below the slope while leaving sediment contained therein on the slope. Another object of the present invention is to provide a vegetation zone with a drainage member that can be implemented together with the vegetation method.

[0011]

Means for Solving the Problems In order to solve the above problems, means according to the first aspect of the present invention will be described with reference numerals used in the embodiment.
Vegetation mat 30 which is holding the fertilizer and plant seeds necessary for vegetation zero together and constituted by attaching the mesh body 20,
The base 11 is formed of a mat body capable of absorbing and passing water.
A part of the formed vertical and horizontal drainage members 10
Attach taken reticulated body 20 such that the lattice shape, a vegetation 100a to be deployed at the slope face 70 above the drainage member 10
Of the horizontal drainage member 10a,
Cover the other part with the impermeable body 12 while exposing it.
And the vertical drainage member of the drainage member 10
10b, the entire side surface excluding the top surface and the end surface of the base 11
By being covered by the water shield 12,
The drainage member 10 absorbs and flows water in about half of the upper side.
For example, it is assumed that can be performed only passed through at the lower side about half, further
A portion of the horizontal drainage member 10a intersecting with the vertical drainage member 10b
For the minute, the cutout 1 is attached to the impermeable body 12 corresponding to this part.
2a is formed to expose the lower surface of the mat body.
The exposed part of the mat body is placed on the mat body on the side of the vertical drainage member 10b.
So as to place the mainly horizontal drainage member 10a drainage member with vegetation, characterized in that the drainage on the slope 70 was collected and so that drainage into each longitudinal drainage member 10b side 10
0a ".

That is, in the vegetation belt 100a with the drainage member of the slope 70 according to the first aspect, a large number of the drainage members 10 are attached to the mesh member 20 to be developed on the slope 70 in a lattice shape. The horizontal drainage member 10a of the drainage member 10
The drainage collected by the horizontal drainage member 10a is drained through the inside of the vertical drainage member 10b while collecting drainage flowing on the slope 70 by the drainage member 10a. . Thus, while the drainage member 10 serving as a sediment dam on the slope 70 prevents further runoff of the earth and sand, the drainage member 10 and the vertical drainage member 10b connected thereto are independent of the slope 70. By forming a lattice-shaped drainage channel, the drainage once collected is prevented from flowing back onto the slope 70.

The vegetation zone 10 with drainage membersAt 0a
Attaches a large number of drainage members 10 to the mesh body 20 in a grid pattern.
Vegetation on this net-like body 20.
Vegetation map with fertilizer or plant seeds
The vegetation method on the slope 70
At the same time as the implementation, to prevent runoff of earth and sand on the slope 70
Vegetation belt with drainage member 100aCan be implemented simultaneously
It is something.

Further, according to the vegetation zone 100a with the drainage member, the net 20 is spread on the slope 70, and
If this net-like body 20 and each drainage member 10 are fixed on the slope 70 by an anchor 41 or a peg 42 as shown in FIGS. And is prevented from floating on the slope 70 which is so-called "non-land", so that drainage on the slope 70 can be performed more effectively. is there.

As shown in FIG. 5 or FIG. 6, if the fertilizer bag 60 and the vegetation base bag 61 are arranged between the horizontal drainage members 10a in the horizontal direction, the vegetation belt 10 with drainage member according to the present invention can be obtained. 0a, the slope 7 with the vegetation mat 30
The vegetation method can be more effectively implemented.

In particular, each of the drainage members 10 is for preventing drainage once collected from leaking to the outside as much as possible. It can also play a role as a "gutter". In particular, the horizontal drainage member 10
As for a, since it is necessary to receive drainage flowing on the slope 70 together with the earth and sand and to absorb the drainage together with the sediment weir, as shown in FIG. The other part is covered with a water shield 12 while mainly exposing the mountain side portion, so that about half of the upper side together with the sediment weir can sufficiently function as a water absorbing material for drainage. Then, as shown in FIG. 3A, the periphery of the lower half of the lateral drainage member 10a is covered with the water shield 12, so that the water shield 12
The mat body inside serves as a gutter.

On the other hand, the vertical drainage member 10b does not actively absorb the drainage flowing on the slope 70, but rather receives the drainage from each horizontal drainage member 10a and flows it downward. Therefore, as shown in FIG. 3B, the entire side surface excluding the top surface and the end surface of the mat body is covered with the water impervious body 12.

With such a horizontal drainage member 10a and a vertical drainage member 10b, there is a problem how to drain the water from each horizontal drainage member 10a to the vertical drainage member 10b side. The vegetation zone 100a is configured as shown in FIG. That is, the portion of the horizontal drainage member 10a that intersects with the vertical drainage member 10b (usually often located at the center) is, as shown in (a) and (b) of FIG. The lower surface of the mat body is exposed by forming a cutout portion 12a in the lower portion, and the exposed portion of the mat body is placed on the mat body on the side of the vertical drainage member 10b. Since the mat body that is the base 11 of each drainage member 10 is rich in water permeability, as shown by arrows in FIG. 4, the drainage collected by each horizontal drainage member 10a is a mat on the vertical drainage member 10b side. It flows on the body and does not flow anywhere else.

On the other hand, the vegetation zone 10 with the drainage member
At the side edge of 0a, the end of each horizontal drainage member 10a is located, and the vertical drainage member 10b is arranged below it. Therefore, as shown in FIG. 4C, the end of each horizontal drainage member 10a is shifted inward so as to cover only about half of the vertical drainage member 10b. Thereby, each horizontal drainage member 10
Since the drainage from the end of a naturally flows down on the upper surface of the vertical drainage member 10b, the drainage absorbed by each horizontal drainage member 10a is efficiently drained to the vertical drainage member 10b side. is there.

The horizontal drainage member 10a and the vertical drainage member 10b described above, or the vegetation zone 10 with a drainage member described below.
For example, a so-called “water-draining sheet” used for sucking out moisture in the embankment and discharging the same to the outside, or a stack of the same, is used as the mat body that is the base 11 of 0b. A thick nonwoven fabric formed so as to be rich in water is used.

[0021] In order to solve the above-mentioned problem, a second aspect is provided.
Means adopted by the invention according to the present invention are described with reference numerals used in the description of the embodiment. "The vegetation mat 30 holding fertilizers, plant seeds, etc. necessary for vegetation on the slope 70 is connected to the reticulated body 20. in together and configured attached to, the base 11 parts

The plurality of drainage members 10 are partially crossed to form a lattice shape.
Attach taken reticulated body 20 so that, a vegetation 100b to be deployed at the slope face 70 on the horizontal drainage portion of the drain member 10
The material 10a is exposed mainly at the mountain side of the base 11.
The other part is covered with the impermeable body 12
And the vertical drainage member 10b of the drainage member 10,
The entire side surface excluding the upper surface and the end surface of the base 11
Each drainage member 1 is covered by
0 means that water can be absorbed and passed in about half of the upper side,
It is assumed that only half water can be passed through, and the upper permeable material 51
And the impermeable material 52 disposed thereunder are formed between them.
Communication passages 53 communicate with each other and open outward.
To form a connecting band 50 , and connect the ends of each of the vertical and horizontal drainage members 10 a and 10 b to the communication path of the connecting band 50.
By inserting into the 53 opening of the mainly drainage horizontal drainage member 10a is on slope which was collected and passed through the communication passage 53 in the connection zone 50 to be able to wastewater in each longitudinal drainage member 10b side Vegetation belt with drainage member 100b characterized by the following "
It is.

That is, the vegetation zone with drainage member 100b according to the second aspect is substantially similar to the vegetation zone with drainage member 100a according to the first aspect, in that the horizontal drainage member 10a and the vertical drainage member 10b employed in the vegetation zone 100a. It is the same,
In order to allow water to flow between the horizontal drainage member 10a and the vertical drainage member 10b, the horizontal drainage member 10a and the vertical drainage member 10b are positively connected to each other by the connection band 50.

In other words, in the vegetation zone 100b with a drainage member according to the second aspect, a part of each drainage member 10 in which the base body 11 is formed of a mat body is covered with the impermeable body 12. The drainage member 1 is the same as the vegetation zone 100a with the drainage member according to the first aspect.
8 are attached to the mesh body 20 in a grid pattern, at the intersections, the connection bands 50 as shown in FIGS.
It is adopted.

As shown in FIG. 9 (b), the connection band 50 is formed by partially integrating the upper part as the water-permeable material 51 and the lower part as the water-blocking material 52. A communication path 53 is formed therein as shown by a dotted line in FIG. That is, the connection zone 50 actively absorbs rainwater or the like from its upper surface, and receives the rainwater or the communication passage 5 from its lower surface.
3 is to prevent the drainage flowing in the inside from leaking out, and the end of each drainage member 10 is inserted into each opening of the communication passage 53.
ON, that is intended to connect. Therefore, this claim 2
In the vegetation zone 100b with a drainage member, each horizontal drainage member 10a
It is not necessary to form the cut-out portion 12a of the water impervious body 12 at the end, and the end of the mat body constituting each drainage member 10 is
That is, it is only necessary to be connected to the communication passage 53 of zero.

By adopting the above-described connecting band 50, not only can water flow between the drainage members 10 be satisfactorily performed, but also the following effects can be obtained. That is, the connection band 50 is attached in advance to, for example, the vertical edge of the mesh body 20, and the vertical drainage member 10b for the communication passage 53 is provided.
If the connection is made at the construction site, the vegetation zone 100b with the drainage member can be rounded as shown in FIG. The mat body constituting the base 11 of the drainage member 10 is rarely sufficiently flexible, and if the drainage members 10 are attached to the net 20 in a lattice form from the beginning, 7 cannot be brought into the state shown in FIG.
If the vegetation zone with drainage member 1 is connected to the
00b can be easily stored and transported.

Finally, in order to solve the above-mentioned problems, a means adopted by the invention according to claim 3 is a method similar to the method described in "The vegetation mat 30 holding fertilizers and plant seeds necessary for vegetation on the slope 70". in the together and constructed by attaching the mesh body 20, the base body
A plurality of vertical and horizontal drainage members 1 in which 11 parts are constituted by cylindrical bodies
0 attach preparative reticulated body 20, a vegetation 100c are developed by the slope face 70 above the drain member 10a · 1 aspect
0b, at least in the upper half of the lateral drainage member 10a, a large number of water passage holes 1 for absorbing drainage on the slope 70 into the cylindrical member.
3 is formed, and the upper permeable material 51 and the shielding provided thereunder are formed.
The water material 52 and the communication passages 53 formed therebetween are
And open to the outside
Each of the drainage members 10a and 10b is formed by forming a connecting zone 50.
The end, the insertion to Rukoto in the opening of the communication passage 53 of the connecting band 50, the mainly horizontal drainage member 10a drainage on slopes which were collected, passed through a communication passage 53 in the connection zone 50 A vegetation zone with drainage member 100c "characterized by being capable of draining to the vertical drainage member 10b side."

That is, in the vegetation zone 100c with a drainage member according to the third aspect, the base 11 of each drainage member 10 to be attached to the mesh body 20 in a lattice shape is constituted by a tube material. This is a fundamentally different point from that according to 2. In other words, what absorbs and drains the drainage is not a mat body partially covered by the water shield 12, but a pipe having a water passage hole 13 formed in a predetermined portion. In order to make the drainage member 10a or the vertical drainage member 10b, the following is performed.

FIG. 10 shows how the horizontal drainage member 10a and the vertical drainage member 10b are configured in the vegetation zone 100c with a drainage member according to the present invention. However, as for the horizontal drainage member 10a, as shown on the right side of the connecting band 50, a large number of water holes 1
3 may be formed. Each of the horizontal drainage members 1 is set while the water holes 13 are positioned upward.
If it becomes troublesome to attach the Oa or connect its end to the communication passage 53 of the connecting band 50, each horizontal drainage member 10 using a pipe material as the base 11 is required.
a may be implemented as shown on the left side of the connection band 50 in FIG.

That is, the horizontal drainage member 10a shown on the left side of FIG. 10 has a large number of water passage holes 13 formed in the entirety of a tube serving as the base 11, and a water permeable material 14 and It is formed by arranging the water impervious body 12 and joining both edges by means such as sewing. In this manner, the upper and lower portions of the pipe material whose upper and lower sides are unclear can be clearly defined by the water impermeable body 12 and the water permeable material 14 that wrap the tube material. Of course, the permeable material 14
Is to be disposed on the upper surface side. Through the water permeable material 14 and the water holes 13, the water flowing on the slope 70 is absorbed to flow into the pipe material, and the pipe material and the water permeable material are absorbed. 14 forms a weir of earth and sand.

A water passage hole 13 also exists on the lower surface side of the pipe material, but the water impervious body 12 exists outside the water passage hole 13. Therefore, the upper half of the horizontal drainage member 10a has water absorption as a whole, The lower half will be a gutter for drainage.
Therefore, even in the case of the horizontal drainage member 10a employing this pipe material, the upper half and the lower half thereof have the same function as the horizontal drainage member 10a in the vegetation zone 100a with the drainage member of claim 1 for example. is there.

On the other hand, as for the vertical drainage member 10b using the pipe material, if the drainage is received from the horizontal drainage member 10a, it is sufficient if the drainage flows down through the drainage member.
The water passage hole 13, the water shield 12 or the water permeable material 14 such as the side of the horizontal drainage member 10a is unnecessary, and it may be a simple cylindrical body.
However, as in the case of the horizontal drainage member 10a described above, a pipe material in which only the upper half has the water passage hole 13 or a water passage hole 13 formed in the whole, and the upper and lower portions of the water passage material 14 and the water shield 1
Needless to say, the present invention may be applied to a case where the pipe material wrapped by 2 is adopted as the vertical drainage member 10b.

The vegetation with a drainage member according to the third aspect of the present invention is that the pipe material used as the base member 11 of the drainage member 10 cannot be sufficiently communicated, particularly if it is not positively connected. It goes without saying that the connection band 50 similar to that of the vegetation band with drainage member 100b according to claim 2 is also used for the band 100c. Since this connection zone 50 is the same as that in the vegetation zone 100b with a drainage member according to claim 2, the reference numerals used in the above description are given in FIG.
Detailed description thereof will be omitted.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a vegetation belt with a drainage member according to an embodiment of the present invention;
100b and 100c, respectively, these vegetation zones with drainage members 100a to 100c will be described below.
The explanation will be focused on.

FIGS. 1 and 2 are a partial plan view and a sectional view, respectively, showing a construction for performing vegetation and drainage on a slope 70 by the vegetation zone 100a with a drainage member according to the first embodiment. The vegetation belt 100a with a drainage member is configured such that a large number of drainage members 10 are attached to the mesh body 20 so as to form a lattice. Since the vegetation zone 100a with a drainage member also performs vegetation on the slope 70, as shown in FIG. 2, a vegetation mat 30 including fertilizers, plant seeds, and the like is integrated on the lowermost surface side. Things. In addition, in the vegetation zone 100a with a drainage member of this embodiment, each drainage member 10 is sandwiched between the mesh body 20 and the vegetation mat 30 in a sandwich shape.

Each drainage member 10 is formed as a long one as shown in FIG. 1, and includes a horizontal drainage member 10a which is to be disposed horizontally on the slope 70 and a slope 70, that is, a vertical drainage member 10b that is arranged in the vertical direction. This claim 1
In the vegetation zone 100a with a drainage member according to
The base body 11 is made of a mat body.
This mat body is, for example, formed into a mat shape while entangled with a fiber made of a synthetic resin, or formed by a foam having continuous pores, or a "water draining sheet" used for draining the embankment. Is adopted. The specific size of the mat body is about 5 cm in width and about 2 cm in thickness in consideration of its manufacture and handling, and workability on the slope 70 as the vegetation zone 100a with drainage members. The most preferred is a plate-like material.

The horizontal drainage member 10a employed in the vegetation zone 100a with drainage member is shown in FIG.
(A) and as shown in FIG. That is, the lower half of the mat body, which is the base 11, excluding both end faces, specifically, about half of the valley side is covered with the water impervious body 12, as shown in FIG. The horizontal drainage member 10a is used. In other words, the vegetation zone 100a with drainage members is required to absorb drainage in about half of the upper side (mountain side) and to use drainage gutters in about half of the lower side (valley side). As shown in FIG. 3A, the lower half of the upper surface, the left side surface in the figure, and the lower surface are covered with the water-blocking material 12, so that the right side surface (mountain end surface) and the upper surface of the mat body are shown. The upper half is exposed so that the water can be absorbed. Of course, the portion surrounded by the water blocking material 12 is a portion constituting a “gutter” for drainage.

In this way, as shown in FIG. 3A, the upper half of the mat body can absorb the drainage flowing on the slope 70, and the horizontal drainage member 10a The sediment that has flowed down toward the mountain can be caught by the surface on the mountain side so that it does not flow down below it, that is, it does not run off. Of course, the drainage that has passed through the sediment dam will be absorbed by the mat body when flowing on the surface of the mat body constituting the horizontal drainage member 10a, and will flow into the horizontal drainage member 10a. Needless to say.

By the way, in order to allow the horizontal drainage member 10a whose base 11 is a mat body to communicate with the vertical drainage member 10b described later, it must be arranged, for example, in an intersecting manner as shown in FIG. However, at the intersection,
If 2 exists, the drainage flowing in the horizontal drainage member 10a will not flow to the vertical drainage member 10b side. Therefore, in the horizontal drainage member 10a, as shown in FIGS. 4A and 4B, the cutoff portion 12 of the water shield 12 is provided at the intersection of the horizontal drainage member 10a with the vertical drainage member 10b.
a is formed in advance. If this cutout 12a is formed, the drainage flowing in the horizontal drainage member 10a flows into the mat body of the vertical drainage member 10b from the lower surface of the mat body. Further, as shown in FIG. 4C, the end of the horizontal drainage member 10a is disposed so as to be located at about half the position on the vertical drainage member 10b. do not do. As a result, the drainage flows from the end of the horizontal drainage member 10a to the upper surface of the vertical drainage member 10b, and in this sense, the horizontal drainage member 10a is located above the vertical drainage member 10b described below. Must cross in this way.

As shown in FIG. 3B and FIG. 4, the vertical drainage member 10b has an upper end surface of a mat body serving as the base 11,
And except for the upper and lower end faces that will be connected to each other,
Non-permeable impermeable bodies 12 on both the left and right sides and the bottom side of the base 11
It is configured to be covered by Vertical drainage member 10
The reason for configuring the b in this way is that the vertical drainage member 10b is used to flow drainage vertically on the slope 70, so that it is easy to handle by the mat body which is the base 11, and That is to say, it can serve as a “gutter” on the slope 70.

The mat body, which is the base 11 of the vertical drainage member 10b, has a shape substantially the same as that of the side of the horizontal drainage member 10a, that is, a strip having a width of about 5 cm and a thickness of about 2 cm. . Thereby, the vertical drainage member 1
0b can be manufactured substantially in common with the horizontal drainage member 10a. As will be described later, the vertical drainage member 10b is provided with flexibility necessary for winding the vegetation belt 100a with the drainage member. It is doing.

Each of the drainage members 10 as described above is attached to the net 20 as shown in FIGS. Further below these drainage members 10, materials necessary for vegetation of the slope 70, such as fertilizers and plant seeds, are placed on the slope 7.
A vegetation mat 30 held and attached to a paper sheet or a non-woven fabric that easily corrodes on the vegetation is attached, thereby completing the vegetation belt 100a with drainage members. Of course, each of the drainage members 10 is arranged vertically and horizontally with respect to the mesh body 20 in a state having the above-mentioned intersections, and is attached in a grid shape as shown in FIG. 1, FIG. 5 or FIG. It is.

The vegetation belt 100a with drainage members is entirely composed of each drainage member 10, the mesh member 20, and the vegetation mat 30.
At the same time, as shown in FIG. 2, the drainage member 10 or the reticulated body 20 is deployed on the slope 70 by the anchor 41 or the peg 42 as shown in FIG. By fixing to the top, the construction is completed. In addition, the anchor 41 is for fixing the vegetation belt 100a with drainage members on the slope 70 at a portion where each drainage member 10 is present, and the peg 42 is for fixing the reticulated body 20 where the drainage member 10 does not exist. It is fixed on the slope 70.

The vegetation zone 100a with a drainage member of the embodiment shown in FIG. 1 is composed of only necessary components, but the vegetation zone 100a with a drainage member is, as shown in FIG. A fertilizer bag 60 may be disposed and fixed between the horizontal drainage members 10a. This fertilizer bag 60
Is a case where good vegetation on the slope 70 cannot be performed only with the fertilizer or the like held on the vegetation mat 30 side, that is, the slope 70
It is suitable for use when the upper part is in a so-called thin state. Further, when it is considered that vegetation on the slope 70 cannot be sufficiently performed only with the fertilizer bag 60, as shown in FIG. 6, the vegetation base bag 61 is inserted between the fertilizer bags 60 and the horizontal drainage member 10a. It is good to carry out by mounting. In each case, the fertilizer bag 60 and the vegetation base bag 61
Since the drainage flowing above is received, the fertilizer and the vegetation base therein are eluted or diffused on the slope 70, and are arranged in the horizontal direction of the slope 70, that is, in parallel with each horizontal drainage member 10a. It is preferable to do so.

The vegetation zone with drainage member 10 according to claim 1
For example, as shown in the upper part of FIG. 7, each of the horizontal drainage members 10a is wound and stored / transported, and as shown in the lower part of FIG. Will be expanded to. For that purpose, the vertical drainage member 10b must have sufficient flexibility. However, since the mat body is formed as described above, the winding of the vegetation belt 100a with the drainage member can be sufficiently performed. It is possible.

In the vegetation zone 100a with a drainage member of the present embodiment, a double thread is formed by knitting the vertical and horizontal yarns of the net 20 in the portion corresponding to the installation of each drain member 10 of the net 20. A portion, that is, a bag-like portion is formed, and each drainage member 10 is inserted into this bag-like portion, so that each drainage member 10 is attached to the net 20 side. This arrangement is very advantageous because the attachment of each drainage member 10 to the net 20 can be performed by means of insertion into a bag-like portion, but it is also very advantageous. 10 may be directly attached to the net-like body 20. When this "spelling device" is adopted, for example, only each of the lateral drainage members 10a is spelled in advance or stored in the above-described bag-shaped portion, and the whole is wound up as shown in FIG. At the construction site, each vertical drainage member 10b may be attached to the mesh body 20 with this spelling device so as to have an intersection with each horizontal drainage member 10a.

The above-mentioned vegetation belt with drainage member 1 according to claim 1
00a, the horizontal drainage member 10a and the vertical drainage member 10b are connected to each other to allow the mat members to communicate with each other.
a and the vertical drainage member 10b are attached to the mesh body 20 so as to have an intersecting portion. However, in order to establish communication between the respective mat bodies, each drainage member is provided as in the vegetation zone 100b with a drainage member according to claim 2. The ends of the members 10 may be connected by the connection band 50.

That is, in the vegetation belt 100b with a drainage member according to the second aspect, as shown in FIGS. 8 and 9, the end of each drainage member 10 is attached in advance to, for example, the back surface of the mesh member 20. It is completed by inserting it into the communication path 53 of the connection band 50 and fixing it to prevent it from coming off.

The connecting zone 50 used in the vegetation zone 100b with drainage members is provided with a water shielding material 52 on the lower surface of the water permeable material 51 to be disposed on the upper side, as shown in FIG. Are arranged, and the water-permeable material 51 and the water-blocking material 52 are sewn or adhered while leaving a cross-shaped communication passage 53 as shown in FIG. It is constituted by integrating by means of (1). Of course, when the connection band 50 comes to the edge of the mesh body 20, the communication path 53 may be formed in a T-shape.
When reaching the corner of the net-like body 20, the communication path 53 may be formed in a key shape. In addition, the vegetation zone 100 with each drainage member
Since a plurality of b's are usually arranged in a horizontal direction on the slope 70, if the communication path 53 of the connecting band 50 coming to the end of the mesh body 20 is formed in a cross shape, the adjacent vegetation belt 100b with a drainage member can be formed. The horizontal drainage members 10a can be connected by the connection band 50.

In what constitutes this connection band 50,
At least the lower side of the communication passage 53 is made of the water shielding material 5.
Must be 2. The reason for this is to prevent the drainage from leaking from the communication passage 53 of the connection zone 50.
Upper vertical drainage member 10b or both horizontal drainage members 1 on both sides
0a, the drainage flowing into the communication passage 53 is transferred to the vertical drainage member 10 extending below the connection zone 50.
This is to completely pass through b. In the connection zone 50 in the present embodiment, the upper one is made of the water permeable material 51. However, this is also used for catching rain falling on the connection zone 50 and drainage flowing thereover. It is considered that the water is collected and flowed into the communication passage 53, and it is considered that such an amount is often small.
May be implemented as the water shielding material 52.

Such a connecting band 50 is formed in advance as a finished product as shown in FIG. 9 and is integrated on the back side of the net-like body 20. When manufacturing or constructing the belt 100b,
Although the end of each drainage member 10 may be inserted into each opening of the communication passage 53 and fixed, the formation of each connection zone 50 and the connection of each drainage member 10 to the connection zone 50 may be simultaneously performed at the construction site. What you can do.

The vegetation zone with drainage member 10 according to claim 2
The configuration of each drainage member 10b is substantially the same as that of the vegetation zone 100a with drainage member according to claim 1, but since the connecting zone 50 as described above is used, the shielding of each horizontal drainage member 10a is performed. Needless to say, it is not necessary to form the cut portion 12a in the water body 12. Although the connecting zone 50 is used, the base material 11 of each drainage member 10 is made of a tubular material.
c.

FIG. 10 illustrates the drainage members 10 of the vegetation belt 100c with drainage members according to the third embodiment, and the drainage members 10 are mats as bases 11 thereof. It is constructed using a tube material instead of a body. That is, as for the horizontal drainage member 10a of each drainage member 10, the connection band 50 shown in the center of FIG.
For example, as shown on the right side of FIG.
As shown in FIG. 10, or as shown on the left side of the connection band 50 in FIG. 10, the water permeable material 14 and the water impervious body 12 are integrated above and below a pipe material in which a large number of water passage holes 13 are formed. What is done is adopted. In any case, about the upper half of each horizontal drainage member 10a is made permeable, and the lower half is made non-permeable.
Each of the horizontal drainage members 10a collects the drainage flowing down the slope 70 at its upper portion, and allows only the horizontal flow of the drainage collected at its lower portion. Things.

As shown in FIG. 10, each of the lateral drainage members 10a has a vegetation zone 100b with a drainage member according to the second aspect.
Are connected to the communication passage 53 of the connection band 50 similar to that in the above, and the collected wastewater is caused to flow to the vertical drainage member 10b side through the communication passage 53. This vertical drainage member 10b also has its base 11
However, unlike the horizontal drainage member 10a, no water holes 13 are formed in the vertical drainage member 10b. The reason is that the vertical drainage member 10b is only required to simply drain the drainage collected by each horizontal drainage member 10a to the lower side of the slope 70. This is because the drainage from the member 10a is collected, and the water holes 13 for collecting rainwater and drainage are not required at all.

In the drainage member 10 thus configured, since the base 11 is a tube, the communication passage 5 of each connection zone 50 is formed.
3 can be relatively easily inserted into the communication path 53. After each tube is inserted into the communication passage 53, the respective tube and the connection band 50 must be fixed. However, the tube is tied by the water passage hole 13 or the connection band 50 and the drainage members 10 themselves are meshed. It may be performed by attaching to the body 20 side, or the following may be performed. That is, the connecting band 50 is attached to the end of each drainage member 10.
The fixing member is attached to the side, and by using this, the fixing member is attached to the connection band 50 side. Specifically, for example, the shielding member which may constitute the horizontal drainage member 10a may be used. The ends of the water body 12 and the water permeable material 14 are used as the attachment portions.
