Description

The present invention relates to, for example, a slope protection tool for protecting a slope such as a slope and a slope protection method.

Conventionally, a slope protection tool composed of a bag-shaped body 51 in which a base material is housed together with vegetation seeds (seed of a plant for greening) and a net-shaped member 52 to which a plurality of the bag-shaped bodies 51 are mounted (FIG. 10 (A)). )) Is installed on the slope (slope) N. Slope protection work is being carried out.

In this slope protection work, as shown in FIG. 10B, the vegetation base 53 is stepped on the mountain side of the bag-shaped body 51 due to the runoff sediment accumulated by being blocked by the bag-shaped body 51, the leaves of trees from the surroundings, and the like. Due to the so-called step effect, which is formed in the step and makes it easier for plants to grow in this step, greening is realized early and well. That is, the small step effect referred to here means an effect in which a growth base layer having a gentler slope than the slope is formed in a small step shape due to the accumulation of earth and sand, and plants can easily grow in this small step.

However, the base material in the bag-shaped body 51 used in the slope protection work is mainly composed of organic matter, and the organic matter is consumed with the passage of time, and depending on the construction environment, the base material may be severely reduced. Then, in this case, a small step is formed from the gap formed between the slope N and the bag-shaped body 51 of the slope protection tool installed on the slope N and the upper side of the bag-shaped body 51 due to this reduction. There is a problem that the vegetation base 53 is washed away and slides down, the vegetation base 53 is not formed on the mountain side of the bag-shaped body 51, and as a result, the small step effect cannot be obtained.

Therefore, it is conceivable to include a curing material that is cured by water absorption in the base material or the bag-shaped body (Patent Document 1). If the cured material is cured by rainfall or the like, the shape of the bag-shaped body 51 is maintained even if the base material is consumed, so that loss of the step effect can be prevented.

Embodiments of the present invention will be described below with reference to the drawings.

In the slope protection method according to the present embodiment, the slope protection tool 1 shown in FIG. 1 is laid on the slope N (see FIGS. 3A and 3B), which is an example of the slope, to protect the slope N. And for greening.

As shown in FIG. 1, the slope protection tool 1 includes a net-shaped member 2 having a substantially rectangular shape, and a mortar bag 3 and a base material bag 4 held (mounted) on the net-shaped member 2.

The net-shaped member 2 has accommodating portions 5 at appropriate intervals in the longitudinal direction. Here, the net-shaped member 2 of this example is, for example, a member having a width of 1 m and a length of 5 to 10 m, and accommodating portions 5 are provided at intervals of 30 cm in the vertical direction. That is, in FIG. 1, only a part of the net-like member 2 (slope protection tool 1) appears. Then, the mortar bag 3 or the base material bag 4 is independently housed in each storage section 5. In the example shown in FIG. 1, the mortar bag 3 is housed in one of the two storage parts 5, and the base material bag 4 is housed in the remaining storage part 5. The accommodating portion 5 is formed in a bag-like shape, a tubular shape, or a pocket shape having a size capable of accommodating the mortar bag 3 or the base material bag 4, and each of the bags 3 and 4 is one end of the accommodating portion 5. It is inserted into the interior from the side, whereby the bags 3 and 4 are held by the net-like member 2.

The net-like member 2 uses fibers having high durability (for example, fibers such as nylon, polyester, aramid, carbon, glass, polyacetal, etc.) or corrosive fibers (for example, fibers such as palm), and has a mesh size of 5 to 10 mm. It is molded to a certain degree, and both of these (durable fibers and corrosive fibers) may be superposed. Further, in order to improve the strength, a wire mesh (for example, a hexagonal wire mesh or a lath wire mesh) may be superposed on the net-like member 2.

The mortar bag 3 is a bag-shaped body 3a having an elongated tubular shape with both ends closed, and containing a dry mortar (curing material) 3b that is cured by water absorption. The dry mortar 3b of this example is a mixture of cement and granular sand as an aggregate, but the aggregate constituting the dry mortar 3b is not limited to sand, but pumice stone (for example, pearlite) or the like is used. Can be done. Further, a reinforcing material such as steel fiber may be mixed with the dry mortar so that the effect of improving the strength of the cured mortar bag 3 can be obtained.

Further, as shown in FIG. 2, the bag-shaped body 3a constituting the mortar bag 3 has a double structure including an inner bag body 6 and an outer bag body 7, and between these two bag bodies 6 and 7. Sheet-shaped high-strength fibers 8 for increasing the strength of the bag-shaped body 3a in the longitudinal direction are arranged. Here, the high-strength fiber 8 is used in at least the longitudinal direction of the bag-shaped body 3a, and the high-strength fiber 8 increases the strength of the bag-shaped body 3a in the longitudinal direction. The high-strength fiber 8 may be joined (for example, heat-sealed or bonded) or connected (for example, sutured) to or both of the bag bodies 6 and 7, and between the two 6 and 7. It may just be inserted. On the other hand, the inner bag body 6 may be simply inserted into the outer bag body 7, or may be directly or indirectly connected to the outer bag body 7 via, for example, high-strength fibers 8. When the inner bag body 6 is only inserted into the outer bag body 7, for example, after the dry mortar 3b is housed in the inner bag body 6, the outer bag body 7 is covered on the outside of the inner bag body 6. You can do it like this.

Here, the bag bodies 6 and 7 can be formed by using a sheet-like body that does not allow the dry mortar 3b to pass through and has water permeability, and the materials thereof include, for example, non-woven fabric, felt, and cloth (woven cloth). ), Knitted fabric, jute cloth, water-decomposable plastic, thin cotton, etc.

Further, as the material of the high-strength fiber 8, synthetic fibers such as polyethylene, polyester, nylon and vinylon manufactured to have high strength for industrial materials, high-strength glass fiber, carbon fiber, aramid fiber and the like are used. Will be done.

The base material bag 4 is a bag-shaped body 4a having an elongated tubular shape with both ends closed, and the base material 4b is housed in the bag-shaped body 4a. The bag-shaped body 4a can be formed by using a sheet-shaped body having water permeability without passing through the base material 4b, and the same material as the bag bodies 6 and 7 can be used as the material. The base material 4b may be a vegetation base material containing, for example, a seed of a plant for greening (vegetation seed), a growth auxiliary material (water retention material, fertilizer, etc.), a soil conditioner, or the like. It may be another normal base material, and may be a mixture of a vegetation base material and a normal base material. The vegetation base material includes, for example, one containing vermiculite as a main component and containing vegetation seeds, a surface soil seed bank, and specifically, a ground near a slope protection target area (greening target area). Examples thereof include those obtained by appropriately mixing growth auxiliary materials such as peat moss, vermiculite compost and water retention material with the surface soil containing vegetation seeds such as forests. In this case, the plant can be surely introduced in a streak pattern. In addition, the normal base material includes a base appropriately selected from materials that do not harm vegetation, such as wood chips, agricultural and marine waste (shells, crab shells, fruit scraps, etc.), paper sludge, and the like. The material is mentioned.

Then, as shown in FIG. 3A, the slope protection method of this embodiment is completed only by laying the slope protection tool 1 on the slope N. In order to lay the slope protection tool 1, for example, the slope protection tool 1 may be fixed to the slope N by driving a fixing member 9 such as an anchor pin. In addition, by laying the slope protection tool 1 on the slope N so that the bags 3 and 4 follow the contour lines, the plants will take root in the soil deposited on the mountain side of the bags 3 and 4, and the greening will be further improved. It is desirable from the viewpoint of obtaining the small step effect that can be achieved early and satisfactorily, and further desirable from the viewpoint of improving the landscape. In addition to the arrangement on the contour lines, the mortar bag 3 may be arranged so as to be orthogonal to the contour lines, and the fixing members 9 may be placed at the intersections to connect them in a grid pattern (not shown). By doing so, it is possible to obtain a construction method having a higher protective effect on the slope N.

Each of the bags 3 and 4 of the slope protection tool 1 laid on the slope N as described above is arranged along the slope N without a gap due to its own weight. That is, each of the bags 3 and 4 has a flexibility of more than a degree that can be stretched along the slope N even if the slope N is uneven. This also applies to the net-like member 2.

Then, as shown in FIG. 3A, the dry mortar 3b is cured as the water is supplied into the mortar bag 3 due to rainfall or the like. After the dry mortar 3b is cured in this way, the mortar bag 3 maintains its shape, and thus the close contact state of the mortar bag 3 with the slope N is maintained, as shown in FIG. 3 (B). In addition, the vegetation base 10 is surely formed by the accumulation of exile sediment on the mountain side of the mortar bag 3, and the above-mentioned small step effect can be obtained.

In particular, when the fixing member 9 is placed, one mortar bag 3 is kept pierced by the plurality of fixing members 9, so that the mortar bag 3 is fixed after the dry mortar 3b is cured. Since it is firmly connected to the head of No. 9 to form an integral structure, the effect of reinforcing the net-like member 2 in both the vertical and horizontal directions can be obtained. In this case, the protective effect from deer trolls is also enhanced. Here, the net-shaped member 2 of this example is obtained by Russell knitting (chain knitting), and the strength in the horizontal direction is inferior to the strength in the vertical direction, and therefore, it tends to shift (elongate) in the horizontal direction. However, this lateral strength is significantly reinforced by the mortar bag 3 after the dry mortar 3b has hardened, and by firmly pressing the slope N with the mortar bag 3, the net-like member 2 expands and contracts. The sex is limited, and the protective function of the slope N surface layer is also improved. That is, only by deploying the slope protection tool 1 and fixing it with the fixing member 9, it is possible to effectively suppress the initial movement of the boulder falling on the slope N, and it is possible to prevent a small collapse caused by the initial movement. Therefore, the slope protection tool 1 is suitable for use on the slope N where small rockfalls are likely to collapse and the slope N where erosion is likely to occur, and also contributes to the suppression of frost heaving of the slope N, and the slope of the present embodiment. The protection method will be applicable as a greening (slope protection) foundation work.

By implementing the slope protection method in which the slope protection tool 1 is laid on the slope N as described above, the vegetation seeds in the base material 4b housed in the base material bag 4 germinate and grow, which is more positive. Greening can be done. Further, even when the slope protection tool 1 does not contain plant seeds, the vegetation base 10 formed in small steps on the mountain side of the mortar bag 3 can effectively capture the flying seeds from the surrounding vegetation. The plant germinates and grows. Therefore, the greening coating on the slope N is ensured over almost the entire surface.

Moreover, the compressive strength of the mortar formed by the dry mortar 3b of the mortar bag 3 is high, but the bending strength is low. Therefore, there is a problem that the mortar after curing is fragile, but a high-strength fiber that enhances the strength of the bag-shaped body 3a. 8 makes the mortar hard to break. Further, the bag-shaped body 3a of the mortar bag 3 is thick and water does not sufficiently permeate into the inside of the bag-shaped body 3a, or the amount of water supplied to the mortar bag 3 is small, so that the dry mortar 3b is sufficient. The bag-shaped body 3a can be reshaped by the high-strength fibers 8 even if it is not cured. Therefore, it is possible to reduce the amount of dry mortar 3b contained in the mortar bag 3 and reduce the thickness of the mortar bag 3. is there.

Further, in the slope protection tool 1 of this example, the high-strength fiber 8 is sandwiched between the inner bag body 6 and the outer bag body 7 in the bag-shaped body 3a of the mortar bag 3, so that the dry mortar is placed in the mortar bag 3. In addition to being able to prevent the high-strength fibers 8 from peeling off when accommodating 3b, the formation of a space in the three-layer structure of the bag-shaped body 3a improves the water retention performance and cures the mortar. It can also be expected that the effect will be enhanced (higher strength).

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be variously modified and implemented without departing from the gist of the present invention. For example, the following modification examples can be given.

When carrying out the slope protection method, the slope protection tool 1 integrated in advance may be laid on the slope N, but for example, the slope protection tool 1 in a state where the bags 3 and 4 are not attached may be used. After arranging on the surface N, each of the bags 3 and 4 may be inserted into the accommodating portion 5. In this case, the slope protection tool 1 can be reduced in weight and transported to the slope N by a small number of people. it can.

Further, the bags 3 and 4 are not limited to those having an elongated bag shape as shown in FIG. 1, and may be, for example, a bag shape having substantially the same aspect ratio. In this case, the configuration of the accommodating portion 5 of the net-like member 2 that holds the bags 3 and 4 may be appropriately changed according to the bags 3 and 4.

It is formed on the underside of the net-like member 2 using a biodegradable material such as rayon, pulp fiber, or synthetic resin, a soluble material, or a water-degradable material, and is configured to allow water and plant buds and roots to pass through. The sheet-shaped member (not shown) may be provided by an appropriate means such as sticking. In this case, a vegetation base material containing a material appropriately selected from vegetation seeds, fertilizers, soil conditioners, water-retaining materials, etc. is attached to the lower surface of the sheet-shaped member with a water-soluble glue material, whereby the sheet-shaped member is adhered. It is desirable that the vegetation base material is supported. The sheet-like member can also be formed by thinly stretching a thin cotton made of rayon.

The sheet-like member and the net-like member 2 may be directly fixed by sticking or the like. For example, after the sheet-like member and the net-like member 2 are arranged on the slope N in a laminated state, an anchor is provided. By placing a fixing member 9 such as a pin, both may be laid on the slope N.

In addition, the member to which the bags 3 and 4 are mounted is not limited to the net-shaped member 2, and may be a mat-shaped or sheet-shaped member. Further, the installation of the bags 3 and 4 can be simplified by using the net-shaped member 2 or the like, but the present invention is not limited to this, and only the bags 3 and 4 may be installed.

Although the net-shaped member 2 shown in FIG. 1 is provided with the accommodating portion 5, the accommodating portion 5 may not be provided, and for example, the bags 3 and 4 may be tied to the net-shaped member 2 with a rope, a wire, or the like.

The slope protection method performed by laying the slope protection tool 1 is suitable for implementation on a slope, and slope N is an example of a slope. For example, the slope protection method is performed on a flat ground or the like. Needless to say, it's good. However, the slope protection method is more suitable for implementation on the slope N in that the small step effect can be obtained.

In the example shown in FIG. 1, the mortar bag 3 is housed in one of the two storage parts 5, and the base material bag 4 is housed in the remaining storage part 5, but the present invention is not limited to this, and one in three. The mortar bag 3 is housed in the storage part 5, and the base material bag 4 is stored in the remaining storage part 5, or the mortar bag 3 is stored in all the storage parts 5 without using the base material bag 4. The ratio of accommodating the bag 3 and the base material bag 4 can be appropriately changed.

The bag-shaped body 3a shown in FIG. 2 has a three-layer structure, but the present invention is not limited to this, and for example, the inner bag-shaped body 6 is eliminated so that the high-strength fibers 8 are exposed inside the bag-shaped body 3a. Alternatively, the outer bag body 7 may be eliminated so that the high-strength fibers 8 are exposed on the outside of the bag-shaped body 3a.

In the mortar bag 3, a core material such as an iron wire or a high-strength fiber rope may be arranged in the longitudinal direction while maintaining the center with a spacer such as a lantern spacer (not shown). By doing so, the mortar bag 3 having higher strength can be obtained, and the bag shape can be obtained after the slope protection tool 1 is laid on the slope N until the dry mortar 3b of the mortar bag 3 is cured or after the curing. The body 3a may be able to maintain a good state along the slope N.

The bag-shaped body 3a of the mortar bag 3 shown in FIG. 2 is provided with high-strength fibers 8 in a tubular shape or a bag shape covering the outer surface of the inner bag body 6 and the entire inner surface of the outer bag body 7. Not limited to this, the high-strength fiber 8 may be configured to increase the strength of the bag-shaped body 3a in the longitudinal direction. Therefore, for example, as shown in FIG. 4 (A), the high-strength fibers 8 are fixed to the sheet-shaped outer bag 7 in a striped pattern, and as shown in FIG. 4 (B), the high-strength fibers 8 are inside. The outer bag body 7 may be rolled into a tubular shape so as to form a bag-shaped body 3a by closing the edge thereof. The inner bag body 6 may be provided in this forming process, or the inner bag body 6 is provided with the high-strength fibers 8 instead of the outer bag body 7, and the inner bag body is provided so that the high-strength fibers 8 are on the outside. 6 may be rolled into a tubular shape. In any case, in the formed bag-shaped body 3a, the high-strength fiber 8 has a portion extending in the longitudinal direction of the bag-shaped body 3a, so that the strength of the bag-shaped body 3a in the longitudinal direction is increased.

Further, in the modified examples shown in FIGS. 4A and 4B, the high-strength fiber 8 has only a portion extending in the longitudinal direction of the bag-shaped body 3a, but a portion extending in the circumferential direction of the bag-shaped body 3a. As an example, as shown in FIGS. 5A and 5B, the high-strength fibers 8 may be arranged in a grid pattern.

Further, the high-strength fibers 8 can be variously provided within a range in which the strength of the bag-shaped body 3a in the longitudinal direction can be increased. For example, as shown in FIG. 6A, the rectangular inner bag-shaped body 6 can be provided. Alternatively, the outer bag body 7 may be provided so as to pass diagonally, or the inner bag body 6 or the outer bag body 7 may be provided so as to extend spirally when the inner bag body 6 or the outer bag body 7 is rolled into a tubular shape (FIG. 6 (B). ) May be used.

If the mortar flows out from the mortar bag 3 due to the supply of water to the mortar bag 3 due to rainfall or the like, the mortar is alkaline and may have an adverse effect depending on the vegetation. Therefore, considering that the mortar flows out from the mortar bag 3 mainly to the valley side of the mortar bag 3, as shown in FIGS. 7, 8 (A) and 8 (B), the inside of the mortar bag 3 is inside the valley side. If the Japanese bag 11 is arranged, the adverse effect on the vegetation due to the outflow of mortar can be suppressed. In order to surely obtain such an effect, when the slope protection tool 1 is laid on the slope N, it is preferable to arrange the slope protection tool 1 so that the neutralization bag 11 is located on the valley side of the mortar bag 3. ..

The neutralizing bag 11 contains the alkali neutralizing agent 11b in a bag-shaped body 11a having an elongated tubular shape with both ends closed. The bag-shaped body 11a can be formed by using a sheet-shaped body having water permeability without passing through the alkali neutralizing agent 11b, and the same material as the bag bodies 6 and 7 can be used as the material. The alkali neutralizing agent 11b is a material obtained by contacting a carbon material treated with, for example, peat moss (acidic) or an acid (for example, a carbonized product obtained by contacting a solution containing calcium chloride and then carbonizing) with hydrochloric acid. ) Can be used.

In the examples shown in FIGS. 7, 8 (A) and 8 (B), the mortar bag 3 and the neutralizing bag 11 are housed in a pair in the accommodating portion 5, and the neutralizing bag 11 for measures against mortar outflow is contained in the mortar bag. Although the example of arranging only on the valley side of 3 is shown, the present invention is not limited to this, and the neutralizing bag 11 may be arranged on the mountain side of the mortar bag 3 as well, and in a form other than the neutralizing bag 11. , The alkali neutralizing agent 11b may be arranged around the mortar bag 3.

As shown in FIG. 9 (A), a fertilizer bag is placed on the mountain side of the mortar bag 3 in order to promote germination and growth of plants on the vegetation base 10 (see FIG. 3 (B)) formed on the mountain side of the mortar bag 3. 12 may be arranged. In the illustrated example, the mortar bag 3 and the fertilizer bag 12 are housed in a pair in one storage part 5. Further, in this case, the base material bag 4 can be used instead of the fertilizer bag 12. As the fertilizer bag 12, for example, the contents of the base material bag 4 can be specialized for fertilizer.

Further, the mortar bag 3, the neutralization bag 11, and the base material bag 4 (or the fertilizer bag 12) may be accommodated in one accommodating portion 5. In this case, it is preferable to arrange the neutralization bag 11 on the valley side of the mortar bag 3 and the base material bag 4 (or fertilizer bag 12) on the mountain side.

Further, in the examples shown in FIGS. 7, 8 (A) and 8 (B), the mortar bag 3 and the neutralization bag 11 are accommodated in one accommodating portion 5, but the present invention is not limited to this, and for example, FIG. 9 (B). ), A plurality of accommodating portions 5 that are continuously arranged in the net-like member 2 may be provided, and the mortar bag 3 and the neutralizing bag 11 may be individually accommodated in each accommodating portion 5. This also applies when the fertilizer bag 12 is used in place of or in addition to the neutralization bag 11.

In the examples shown in FIGS. 8A and 8B, of the mortar bags 3 and the neutralizing bags 11 housed in pairs in one housing portion 5 when the slope protection tool 1 is laid on the slope N, The fixing member 9 penetrates only the neutralizing bag 11 on the valley side and presses the mortar bag 3 on the mountain side with the bent head of the fixing member 9, but the mortar bag 3 and the neutralizing bag 11 are individually fixed. It may be fixed by penetrating at 9. As shown in FIGS. 3A and 3B, the mortar bag 3 independently housed in the housing part 5 is individually pierced by the fixing member 9 and fixed to the slope N, and is fixed to the slope N. 4 is also fixed in the same manner.

Needless to say, the above modified examples may be combined as appropriate.
