DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the “greening structure of a wall surface in a concrete structure and its construction method” of the present invention will be specifically described based on the drawings. In this description, first, the concrete structure 1 will be described, and then various members used in the “greening method of the wall surface in the concrete structure” will be described. Then, while explaining “the greening method of the wall surface in the concrete structure”, the resulting “greening structure of the wall surface in the concrete structure” will be described together.
[0016]
What is indicated by reference numeral 1 in the figure is a concrete structure. In this embodiment, as an example, it is constructed as a countermeasure against disasters such as debris flow, mountain collapse, cliff collapse in the mountainous valley region described in the background of the invention. However, it may be a structure built in mountainous areas such as retaining walls and dams as described in the background of the invention, and moreover it is a structure built in an urban area such as a building or a house. It does not matter.
[0017]
The sabo dam that is the concrete structure 1 is designed after considering variously in terms of strength, proof stress, and cost whether it is unreinforced concrete or reinforced concrete. In this embodiment, a hollow dam is designed as an example. It is made of concrete (hollow gravity type). When constructing this material, first excavate the ground and put out the rock, and if there are cracks, seams, etc. in this rock, inject cement to reinforce it.
Next, the bedrock surface is washed, the floats are removed, a mold is formed, and concrete is placed there.
As an example, the concrete structure 1 obtained in this way has a dike height of several meters to several tens of meters, a dike length of several meters to several tens of meters, and a dike width of several tens of centimeters to several meters. A through 2 is provided. Further, as shown in FIG. 3, the cross-sectional shape was such that the upstream surface 3 (mountain side) was a vertical surface and the downstream surface 4 was a slope.
[0018]
As shown in FIGS. 1, 2, and 3, a plurality of grooves 5 are formed along the longitudinal direction of the downstream surface 4, which is one of the wall surfaces of the concrete structure 1. It can be changed as appropriate. As shown in FIG. 3 (a), the groove 5 is a square of 20 cm × 20 cm (as appropriate depending on the size of the vegetation bag 20) as an example of the cross-sectional shape. A slope that rises toward the downstream surface 4 is formed.
That is, in this case, even when the angle between the groove bottom 5 a and the downstream surface 4 is set to 90 °, the groove bottom 5 a forms a slope that rises toward the downstream surface 4.
[0019]
Next, various members used in the “wall greening method for concrete structures” will be described.
The vegetable long fiber woven fabric 6 is a sheet-like member having a thickness of about 10 mm obtained by flattening relatively inexpensive plant fibers such as palm and hemp and sprinkling or mechanically entwining the adhesive. is there. In this embodiment, as an example, a sheet of several tens of cm × several tens of cm is used as one unit.
In this embodiment, palm is used as the plant fiber, and the color is light brown. Further, chemical fibers can be used in place of the plant fibers. However, since the roots of the plants P are stretched in the plant long fiber woven fabric 6 as will be described later, it has water retention. It is also preferable to use plant fibers.
[0020]
The net 9 is a 10 mm mesh net, and the material is a synthetic fiber (nylon or the like) and the color is green.
Although the plant fiber can be used instead of the synthetic fiber, as will be described later, the net 9 covers the plant long fiber woven fabric 6 and plays a role of holding this, so that the change with time is small. Synthetic fibers that do not cause a decrease in strength are preferred.
[0021]
Next, the soil stopper 10 will be described. This is a device related to utility model registration (Registration No. 2541425) by the applicant of the present application, and is composed of a stopper plate 11 and a stopper pin 15 as shown in FIG. A U-shaped reinforcing bar 12 is used as a frame member, and a mesh body 13 is stretched over the reinforcing bar 12, and two sleeves 14 are provided on one surface of the mesh body 13. The stopper plate 11 has a size of 45 cm × 8 cm (having two sleeves 14) or 100 cm × 8 cm (having three sleeves 14) as an example. The length can be varied.
[0022]
In the embodiment shown in FIG. 4, the support surface of the stopper plate 11 is the net body 13, but in addition to this, the root of the plant P is formed by providing a large number of holes on the flat plate or by providing a plurality of long hole-shaped slits. It can be set as the structure which can pass through. Further, by using the reinforcing reinforcing bars 12 and providing round rods with a small diameter in a saw-like shape with a certain interval, a through structure can be configured.
Further, the stopper plate 11 having the flat plate shape shown in FIG. 4 is the most versatile and easy to use. However, when the use is limited such that a plant having a special shape is planted, both ends are vertical or It is possible to adopt a bowl-shaped configuration that stands up diagonally.
[0023]
Next, the vegetation bag 20 shown in FIG. 5 will be described. This vegetation bag 20 is made of resin fiber fiber nets 21 so that it can ventilate, pass water, and pass through the roots of the plant P, and is adapted to a seedling inside. The mixed soil 22 is stored. In the present embodiment, resin fibers are used as the material of the fiber net 21, but plant fibers such as hemp and cotton can also be used.
[0024]
Hereinafter, the “greening method of the wall surface in the concrete structure” of the present invention will be described.
(1) Construction of the concrete structure First, excavate the ground and put out the rock, and if there are cracks, seams, etc. in this rock, inject cement to reinforce it.
Next, the bedrock surface is washed, and the formwork is formed after removing the float stones. Concrete is placed therein, and when the concrete solidifies, the formwork is removed and the concrete structure 1 is constructed.
[0025]
(2) Application of vegetable long fiber woven fabric And, as shown in FIG. 3, at least the downstream surface 4 as the wall surface and the groove bottom 5a of the groove 5 formed on the downstream surface 4 are provided with the vegetable long fiber woven fabric 6. The concrete nails 7 are driven and pasted at appropriate intervals. In this pasting, it is preferable to fold one vegetable long fiber woven fabric 6 and continuously provide it from the groove bottom 5a to the downstream surface 4, but the downstream surface 4 and the groove bottom 5a are separated and individually provided. You may make it stick to. In addition, since the concrete nail 7 is further driven when the net 9 described later is covered, it may be temporarily fixed at this point.
In the embodiment shown in FIG. 3, the vegetable continuous fiber woven fabric 6 is attached only to the downstream surface 4 and the groove bottom 5 a, but it may be applied to the entire region in the groove 5.
Moreover, when it is necessary to consider the scenery from an upstream side or the upper part especially, the vegetable long fiber woven fabric 6 may be affixed on the upstream surface 3 and the wall top part.
[0026]
(3) Hole for stopper pin Next, a hole 15a for driving the stopper pin 15 for fixing the soil stopper 10 is appropriately drilled using a drill, and the position of the soil stopper 10 after installation is The position is set so that the stopper plate 11 serving as the support surface is in contact with the groove bottom 5a of the groove 5 (whether it is an extended line shape or a bent shape, but there is no step). In the present embodiment, the groove bottom 5a is formed as an extended line because it forms a slope that rises toward the downstream surface 4. In this embodiment, the hole 15a is drilled 30 mm below the groove bottom 5a.
If the stopper plate 11 is 45 cm × 8 cm, two holes corresponding to the sleeve 14 are drilled, and if the stopper plate 11 is 100 cm × 8 cm, three holes corresponding to the sleeve 14 are drilled.
The drilling of the hole 15a in the downstream surface 4 may be performed before the vegetable continuous fiber woven fabric 6 is attached.
[0027]
(4) Net Covering Next, the vegetable long fiber woven fabric 6 is covered with the net 9, and a concrete nail 7 having a diameter of 6 mm and a length of about 50 to 60 mm is used with a washer 8 having a diameter of about 35 to 40 mm. The net 9 is fixed by driving into the downstream surface 4 using about 12 per 1 m ² as a guide.
[0028]
(5) Installation of soil stopper Next, the stopper pin 15 is inserted into the sleeve 14 provided on the lower surface of the stopper plate 11, and the stopper plate 11 is moved to the downstream surface 4 by driving the pointed end into the hole 15 a formed in the downstream surface 4. Fix against.
At this time, it is preferable to use a washer 8 of about 35 to 40 mm and press down the vegetable long fiber woven fabric 6 and the net 9.
In this way, a plurality of soil stoppers 10 are installed in a multi-stage shape (as an example, at an interval of 920 mm) along the groove 5 as shown in FIGS.
[0029]
(6) Installation of the vegetation bag And the vegetation bag 20 is pushed into the groove 5, and at this time the vegetation bag 20 is held by the groove bottom 5a and the stopper plate 11 as shown in FIG. About 1/3 (15 cm) protrudes from the groove 5.
Furthermore, the vegetation bag 20 is fixed by using a holding band 16 having hooks on both ends of the belt-like rubber, and stretching the holding band 16 between two points of the reinforcing bar 12 or the net body 13 in the stopper plate 11. Of course, you may make it fix by driving a pin into the middle part of the vegetation bag 20 suitably.
[0030]
(7) Planting of the plant and driving in the stop pin When the construction method so far is completed, the upper part of the portion protruding from the downstream surface 4 of the vegetation bag 20 is cut open, and plants P such as flowers and trees are planted from this cut end, Further, a hook-shaped opening pin 23 is inserted between the fiber nets 21 divided by the cut end.
The plant P is appropriately selected, and moss growing 80 to 100 cm per year is preferable. In addition, the reason why the grooves 5 are formed in a multi-stage shape at intervals of 920 mm is because it is premised on planting moss, and when planting other plants P, the groove interval may be appropriately changed. .
[0031]
In order to simplify the construction method, the plant P may be installed in the groove 5 and the soil stopper 10 in a state of being planted in the vegetation bag 20.
In addition, since plant P seedlings have appropriate planting times depending on the variety, if the construction up to this point is out of time, only plant vegetation bag 20 is installed, and then plant P is planted at the appropriate time. To ensure the safety of training.
[0032]
(8) Harmony between subsequent plant growth and surrounding environment The “wall planting method for concrete structures” of the present invention is carried out as described above, and as a result, the “wall surfaces of concrete structures of the present invention” Can be constructed. At this point, since the downstream surface 4 is already covered with the vegetable long fiber woven fabric 6 and the net 9, the color of the surrounding landscape (mountain forest) is naturally incorporated, and there is no unnatural feeling peculiar to the artificial building. It is.
[0033]
Eventually, as the plant P grows, the vine extends upward from the planted portion and spreads along the plant long fiber woven fabric 6 and the net 9 that are obediently attached to the downstream surface 4. Further, the roots extend through the vegetable long fiber woven fabric 6 affixed to the groove bottom 5 a and through the stopper plate 11 and into the vegetable long fiber woven fabric 6 affixed to the lower downstream surface 4.
[0034]
Moreover, since the groove bottom 5a in the groove 5 forms a slope that rises toward the downstream surface 4, an appropriate amount of water accumulates in this portion due to rain and water spray. Further, water is retained between the fibers of the vegetable long fiber woven fabric 6.
Further, the plant-based long fiber woven fabric 6 can prevent the burning of concrete in the summer, and can prevent the plant P from being weakened by the heat retaining effect in the winter.
And with the growth of the plant P, after several months, the downstream surface 4 is covered with the vine of the plant P, and the concrete structure 1 can be brought into a more natural state.
[0035]
[ Reference form related to the present invention ]
Next, a reference example related to the present invention in the technical idea will be described. In the previous embodiment, the grooves 5 are formed in a multistage shape along the longitudinal direction of the downstream surface 4 (horizontally). It can also be formed vertically as shown in FIG.
[0036]
In addition, the “wall greening structure and its construction method in a concrete structure” of the present invention can also be applied to an existing concrete structure 1, and is a part surrounded by an imaginary line in FIG. Can be unitized and retrofitted onto the wall surface of the concrete structure 1 to greenen the wall surface of the existing concrete structure 1.
[0037]
In the previous embodiment, the upstream surface 3 (mountain side) of the sabo dam as the concrete structure 1 is a vertical surface, the downstream surface 4 is a slope, and the downstream surface 4 is a construction surface. 4 may be a vertical plane.
Also in this case, the groove bottom 5a in the groove 5 forms an inclined surface that rises toward the downstream surface 4, and the angle between the groove bottom 5a and the downstream surface 4 becomes an acute angle as shown in FIG. 3B. To.
[0038]
【The invention's effect】
The “greening structure of a wall surface in a concrete structure and its construction method” according to the present invention is constituted as described above, and exhibits the following effects.
First, the vegetation bag 20 can be supported in a state protruding from the wall surface. Therefore, by planting the plant P on the protruding portion, the plant P can be extended without difficulty, and the plant P is grown. In addition, the wall can be reliably covered by growing the plant P.
[0039]
Moreover, an appropriate amount of water can be accommodated in the inside of the groove 5 due to rainfall and watering, which can contribute to the growth of the plant P. Moreover, since excess water overflows from the boundary between the groove bottom 5a and the wall surface, root rot or the like is not caused.
[0040]
Furthermore, since the contact surface between the soil stopper 10 and the vegetation bag 20 does not have a step, excessive stress is not applied to the vegetation bag 20 and the vegetation bag 20 is not damaged.
[0041]
Furthermore, even before the plant P grows, the wall surface can have a natural color, and the concrete structure 1 that does not impair the scenery can be obtained. In addition, the wall surface can be provided with water retention, and the roots of the plant P can be stretched without being damaged. In addition, the concrete can be prevented from burning in the summer, and the plant can be prevented from deteriorating due to the heat retaining effect in the winter.
[0042]
Furthermore, the vegetable long fiber woven fabric 6 can be prevented from falling off by supporting the vegetable long fiber woven fabric 6 throughout. In addition, since the vine and roots of the plant P can be entangled, the vine can extend over the entire wall surface, particularly in the case of cocoon-based plants.
[0043]
Furthermore, fraying of the fiber net 21 can be prevented, and the mixed soil 22 and the plant P can be prevented from flowing out.
And by these, the novel "greening structure of the wall surface in a concrete structure and its construction method" which can fix the plant P with respect to the wall of the concrete structure 1 can be provided.
