DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protection structure for slopes, walls and the like using a grid frame fence.

[0002]

2. Description of the Related Art Rock slopes, concrete / mortar spray slopes, and walls of concrete structures such as retaining walls and dams,
Because there are many problems on landscape conservation, introduction of protection and greening by vegetation is considered. Japanese Patent Application Laid-Open No. Hei 4-213625 discloses that a grid frame fence composed of an inclined front wall and a horizontal bottom wall made of a reinforced grid is installed in front of a slope, and a grid frame fence is provided below the bottom wall of the grid frame fence. Reinforcement fleece is laid on the front of the lattice fence and the top of the bottom wall, and a greening sheet is laid.Filling material is filled between the lattice fence and the slope. A protective structure of a slope constructed in multiple stages by repeating from above to above is disclosed. This protective structure can be constructed even on steep slopes, and has excellent points such as good construction efficiency.

[0003] In the above protective structure, the reinforcing fleece (reinforcing member) spreads over the bottom wall portion into the embankment material, and serves to anchor the lattice fence to the embankment material and stabilize the embankment material. For this reason, the bottom wall can be shortened, and transportation of the lattice frame fence becomes easy. As reinforcing members to be laid under the bottom wall of the lattice frame fence, "flexible plastic net" (Japanese Patent Laid-Open No. 3-51423) and "fibers formed by molding a polymer material into a lattice shape" Well-known and commonly used geotextiles such as grids, polymer grids, geonets, and geofabrics ”(JP-A-3-592).
No. 20), "Net-shaped geotextile made of glass fiber impregnated with synthetic resin" (Japanese Patent Application No. 5-13)
6563) are known.

Here, the term "geotextile"
It refers to a type of reinforcing member used with soil, rocks, etc., but its definition (particularly the range of types) varies widely. Geotextile in a narrow sense means a knitted fabric, woven fabric, nonwoven fabric, a combination thereof, and the like made of a fiber material. Geotextiles in a broad sense include not only geotextiles in a narrow sense but also geonets and geos made of non-fiber materials (such as resin). Also includes geotextile-related products such as grids and combinations of these. In the above known publications, the term geotextile is used in a broad sense, but in the present specification, the term geotextile is used in a narrow sense.

[0005]

A geotextile such as a knitted fabric, a woven fabric, or a nonwoven fabric made of a fiber material has a feature of high strength in spite of being lightweight and flexible. In particular, nonwoven fabrics have thick and high-strength products. Also,
Due to the capillary action of the fiber material, it also has the function of guiding the water contained in the embankment material to the front and draining it. However, geotextiles (especially high-strength nonwoven fabrics) are expensive, and thus have a problem in that the construction cost increases.

On the other hand, geotextile-related products such as geonets and geogrids made of non-fiber materials are relatively inexpensive, and their use has been increasing in recent years. However, compared to geotextiles, springback (which tends to curl elastically when spread at the construction site because it has a curl due to roll winding after production) occurs, making it difficult to handle, lower strength, drainage function Because there is almost no
There was a problem that the embankment material was liable to soften due to water content.

Accordingly, an object of the present invention is to provide an embankment material in a protection structure such as a slope or a wall using a grid frame fence having excellent points such as being able to be constructed even on steep slopes and having good construction efficiency. The amount of geotextile used as a reinforcing member to be moored in the building can be saved, and construction costs can be reduced. It is to provide a protective structure that can be obtained.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is directed to a reinforced steel grid comprising an inclined front wall portion and a horizontal bottom wall portion, which are provided in front of a surface to be protected such as a slope or a wall. Grid frame fence, and reinforcing members laid under the bottom wall of the grid frame fence, embankment material filled between the grid frame fence and the surface to be protected, filler such as rock One step is constituted by, and in a protection structure such as a slope, a wall surface and the like constructed in multiple steps by stacking the steps from the bottom to the top, as the reinforcing member, a geotextile made of a fiber material and a non-fiber material are used. It is characterized in that geotextile-related products are used alternately for each stage, for a plurality of stages, or for each irregular stage.

Here, "slope" which is one of the surfaces to be protected
The type of rock is not particularly limited,
Examples include mortar spraying slopes, cut slopes, and embankment slopes. Similarly, the type of the “wall surface” is not particularly limited, and may be a wall surface of a concrete structure such as a retaining wall or a dam.

[0010] Examples of the "filler" include embankment materials, rocks, mixtures thereof, and mixtures thereof with clinker ash, fly ash or asphalt waste materials. The embankment material is preferably soil at the construction site, but may be soil carried from another place. The size of the rock is not particularly limited, and includes large crushed rock to gravel of about 2 to 75 mm.

Examples of the "geotextile made of a fiber material" include a knitted fabric, a woven fabric, a nonwoven fabric, a combination thereof, and the like made of a fiber material. In particular, a thick, high-strength nonwoven fabric is preferred. The geotextile has an effect of mooring the grid frame fence to the embankment material, an effect of stabilizing the embankment material, and a drainage effect.

Examples of "a geotextile-related product made of a non-fiber material" include a geonet formed by fusing extruded resin strands in a mesh shape, a geogrid formed by stretching a perforated resin sheet, and the like. In particular, a geogrid whose strength is increased by stretch molding is preferable. Geogrids include uniaxial stretching and biaxial stretching. Geotextile-related products have the effect of mooring the grid frame fence to the embankment material,
It acts to stabilize the embankment material.

The reinforcing member can be fixed at its end to the surface to be protected. In this case, the reinforcing member has the same function as the next anchor.

Further, by fixing an anchor to the surface to be protected and connecting the grid frame fence to the anchor with a connecting member, the movement of the grid frame fence can be strongly prevented. The shape and length of the anchor can be appropriately determined according to the surface to be protected.
The connecting material is not particularly limited as long as it has a sufficiently high strength to connect and hold the grid frame fence to the anchor.
Examples include a metal chain, a synthetic resin rope, and a glass fiber rope. Regarding the method of connecting the anchor and the connecting member, even in a mode in which a locking portion is provided on the anchor and one end of the connecting member is directly connected to the locking portion, the mounting member extending along the surface to be protected is fixed to the anchor. Then, an embodiment may be adopted in which one end of the connecting member is connected to the anchor member so as to be indirectly connected to the anchor. Examples of the attachment material include a rod material, a pipe material, an angle material, and a rail material.

It is preferable that a greening sheet is provided on the rear surface of the front wall of the lattice frame fence and on the upper surface of the bottom wall. The sheet for greening can prevent spilling and erosion of the filler, does not hinder the growth of the plant, and is not particularly limited as long as it is water-permeable, and examples thereof include a slightly coarse cloth and water-soluble paper. it can. Particularly preferred are microorganisms such as bacteria in soil (bacterium in soil is called bacteria,
There are bacteria, filamentous fungi, actinomycetes and the like. ) Is a greening sheet made of a biodegradable material that is decomposed and disappears. Examples of the biodegradable material include a starch compound, a protein compound, a vinyl emulsion compound, a polylactic acid compound, a blend of starch and a resin, and at least one selected from these. After the seeds germinate and grow and the construction surface is stabilized, the greening sheet made of the biodegradable material is decomposed by microorganisms in the soil and eventually loses its shape because it cannot maintain its shape.

It is preferable that a vegetation material including soil, seeds, and the like be attached to a filler or a greening sheet that appears through the front wall of the lattice frame fence. As this vegetation material, artificial soil, a sprayed layer formed by spraying a mixture of seeds, etc.
An example is a sandbag containing seeds or the like. The spray layer is made by spraying materials such as artificial soil, seeds, fertilizer, curing agent (coagulant to stabilize the spray layer) and soil activator (to activate microorganisms). A spraying layer having a thickness of about 10 to 30 mm by the "soil spraying method", or a thickness of about 30 to 100 mm (or more) by the so-called "thick layer base material spraying method" in which the same material is sprayed dry.
A spray layer can be illustrated. Seeds are at the construction site soil, construction season,
It is appropriately selected according to weather conditions and the like. The spray layer may be a single layer or a plurality of layers.

The inclination angle formed by the front wall portion of the lattice frame fence and the bottom wall portion may be constant in all stages, but may be set to be larger for each stage or for each of a plurality of stages. Specifically, the following modes (a), (b), and (c) can be exemplified. (A) The inclination angle of the front wall portion at the first stage (lowest stage) is, for example, 60
Degrees, and the inclination angles of the front wall portions of the second stage or more are 62 degrees, 6
4 degrees, 66 degrees, 68 degrees, etc.
An aspect set to increase by 0 degrees. The increment of the inclination angle may be constant between the stages or may be changed in the middle (for example, in the same example, 60 degrees, 64 degrees, 67 degrees, 69 degrees, 7 degrees).
0 degrees ...). (B) The inclination angle of the front wall of the first to third steps is, for example, 60 degrees, and the inclination angle of the front wall of the fourth to sixth steps is, for example, 64 degrees. An aspect that is set so as to increase by degrees. The increment of the inclination angle may be constant between the stages or may be changed in the middle. (C) An embodiment in which the embodiment (a) and the embodiment (b) are mixed.

Further, a part of the reinforcing bar constituting the lattice frame fence (for example, a part requiring particularly high strength) may be thicker than other reinforcing bars. Thereby, it is possible to prevent a phenomenon in which a part of the rebar is bent and deformed to the front side due to the pressure of the filler or the like.

[0019]

BEST MODE FOR CARRYING OUT THE INVENTION

<< First Embodiment >> FIGS. 1 to 3 show a protection structure for a rock slope according to a first embodiment of the present invention. The protection structure is constructed by the following steps. The rock slope 1 is, for example, about 6
It is a steep slope of 0 degrees.

[Installation process of lattice frame fence] In the first stage, as shown in FIG.
Non-woven fabric 3 as a geotextile of reinforcing material
a, and a required number of lattice frame fences 5 are arranged side by side on the nonwoven fabric 3a. As shown in FIG. 1, the lattice frame fence 5 includes an inclined front wall portion 6 and a horizontal bottom wall portion 7. As an example of a manufacturing method, a reinforcing bar is welded in a vertical and horizontal lattice shape (specifically, arc welding). Is formed by bending a reinforcing bar lattice formed by welding at the center. The upper end of the front wall 6 and the rear end of the bottom wall 7 may be connected by a connecting rod with a hook or the like. Non-woven fabric 3
a is spread to the rock slope 1 side beyond the rear end of the bottom wall 7. Reference numeral 15 denotes a pile for fixing the bottom wall 7 of the lattice frame fence 5 to the nonwoven fabric 3a. The distance between the front wall portion 6 of the lattice frame fence 5 and the rock slope 1 is not particularly limited, and is, for example, about 2 in the present embodiment.
000 to 5000 mm.

The dimensions and the like of the lattice frame fence 5 used in the present embodiment are as follows, but are merely examples, and these dimensions and the like are appropriately changed depending on the construction site. Angle of inclination of front wall 6 with bottom wall 7: about 60 degrees Length of inclination of front wall 6: about 600 mm Depth of bottom wall 7: about 600 mm Left and right length of front wall 6 and bottom wall 7: about 2600mm Diameter of reinforcing bar: about 10mm Grid pitch of reinforcing bar grid: 100 to 300mm

[Greening sheet laying step] A slightly rough greening sheet 8 is laid on the rear surface of the front wall 6 of the lattice frame 5 and the upper surface of the bottom wall 7. It is preferable that the upper end of the greening sheet 8 be slightly left behind and temporarily suspended on the front surface of the front wall portion 6 (not shown). The greening sheet 8 is not limited to a specific material, and examples thereof include a woven fabric and a nonwoven fabric.

[Embedding Material Filling Step] The embankment material 9 is filled between the lattice fence 5 and the rock slope 1 by using soil at the site. The embankment material 9 is compacted with an impact roller or the like. The remaining upper end of the greening sheet 8 is placed on the upper surface of the embankment material 9. This forms the first stage.

[Multi-step repetition step] The above-mentioned step of installing the grid frame fence, laying the sheet for greening, bending the end of the horizontal reinforcing bar, and filling the embankment material are performed on the upper surface of the embankment material 9 to form two steps. Form the eyes. However, as shown in FIG. 3, the reinforcing member to be laid in the second stage is a geogrid 3b (a geotextile-related product) formed by uniaxially stretching a perforated resin sheet. As described above, the geogrid 3b is likely to undulate due to springback, and therefore it is preferable that the undulation be suppressed by the pile 14. This operation is repeated from the bottom to the top to construct the lattice frame fence 5 and the embankment material 9 in multiple stages. Non-woven fabric 3a and geogrid 3
and b are alternately used for each stage. In the uppermost lattice frame fence 5, the upper end of the vertical reinforcing bar of the front wall portion 6 is bent rearward and downward (not shown).

[Spraying Layer Forming Step] On the front surface of the greening sheet 8 that appears through the reinforcing grid of the front wall 6 of the grid frame fence 5,
A spray layer 16 including seeds and artificial soil is spray-formed. In the present embodiment, the spray layer 16 having a thickness of about 60 mm was formed by the above-mentioned “thick layer base material spraying method”.

[Vegetation Member Attaching Step] Through holes are provided in the spraying layer 16 and the vegetation greening sheet 8 at various places, and the vegetation members 10 are driven or inserted into the embankment material 9 at a required angle through the through holes. Mounting. The vegetation member 10 is a tubular body formed of a biodegradable material and opened at both ends, and a large number of through holes 11 are formed in the tubular wall over substantially the entire length and the entire circumference. This through hole 11 can be omitted. As the biodegradable material, those exemplified above can be used. Here, a blend of starch and a polyester resin is used. The inside diameter of the vegetation member 10 in the illustrated example is about 5
0 mm and length is about 300 mm. The inner diameter of the vegetation member 10 varies depending on the type of greening plant to be planted, and is not particularly limited, but is preferably 20 to 150 mm. The length of the vegetation member 10 depends on how much the extension direction is controlled, and is not particularly limited.
0 mm is preferred. The mounting angle of the vegetation member 10 can be variously set within the range of 80 degrees from horizontal to horizontal.
In addition, the vegetation member 10 is not limited to a cylindrical body, and may have a half cylindrical wall or a channel wall.

In the soil inside the vegetation member 10, the plant 1 for greening
2 is planted or planted in the form of seeds, seedlings or cuttings.
The type of the plant 12 for greening is not particularly limited, but is not particularly limited, as follows:
Examples include cedar, hinoki, yasabushi, beech, radishes, poplar and the like. It is preferable that a functional agent such as a fertilizer, a soil conditioner, or a molding agent is mixed with soil and loaded into a deep place inside the vegetation member 10 to promote the growth of the plant 12 for greening.

According to the protection structure of the rock slope 1 constructed by the above-described method, the use of the lattice frame fence 5 enables construction even on steep slopes, and does not require heavy equipment for construction and enables manual work. Available, easy to construct, does not require much manpower, has good construction efficiency, can shorten construction period, can easily cope with curved rock slope 1, can use on-site soil as embankment material 9, etc. The effect of is obtained.

Since the spraying layer 16 containing seeds and artificial soil is spray-formed on the front surface of the greening sheet 8, the germination and growth of the seeds are better than when the seeds are simply incorporated in the greening sheet. Primary vegetation by germination of seeds such as Western turf can be achieved in a short period of time. After that, the woody plants grow.

The vegetation member 10 functions to prevent erosion of the soil around the root system of the greening plant 12,
It has the function of retaining the water contained in the soil and the function of controlling the direction of extension of the root system by changing the mounting angle. In addition, the vegetation member 10 made of a biodegradable material collapses several months to several years after construction, and does not hinder the growth of the root system.

Further, in this embodiment, the nonwoven fabric 3a and the geogrid 3b are alternately used for each step as the reinforcing member, so that the strength and drainage function of the entire protection structure are almost the same as when the nonwoven cloth is used for all the steps. Can be obtained. That is, the nonwoven fabric 3a and the geogrid 3b spread in the embankment material 9 beyond the bottom wall portion 7, and have the effect of anchoring the grid frame fence 5 to the embankment material 9 and stabilizing the embankment material 9. In particular, the nonwoven fabric 3a provided for each stage has high strength, so that it is not easily cut even by earth pressure, and exhibits a strong reinforcing action.
Further, the nonwoven fabric 3a has a function of guiding the water contained in the embankment material 9 to the front and draining it by the capillary action of the fiber material, so that even if there is a large amount of rainfall, the embankment material 9
There is no danger of softening. By using the relatively inexpensive geogrid 3b for each stage, the expensive nonwoven fabric 3
The use amount of a can be saved, and the construction cost can be reduced.

Instead of the geogrid 3b, as shown in FIG. 4, a geogrid 3b composed of a vertical strand 22 reinforced with aramid fibers 21 and a stretched horizontal strand 23 can be used. . Further, instead of the nonwoven fabric 3a, as shown in FIG. 5, a composite fabric 3c formed by coating a mesh fabric such as polyester fiber with a resin can be used.

Second Embodiment Next, FIG. 6 shows a protection structure for a rock slope 1 according to a second embodiment, in which an anchor 32 is fixed to the rock slope 1 and a grid is attached to the anchor 32. The point at which the frame fence 5 is connected by the connecting member 34 and the inclination angle formed by the front wall 6 and the bottom wall 7 of the lattice fence 5 are set to be larger toward the upper level (specifically, the first level (lowest level)). Is set to, for example, about 50 degrees, and the inclination angles of the second and subsequent steps are increased by 1 to 5 degrees for each step.) The structure of the corner is the same as in the first embodiment.

In the present embodiment, a large number of mounting holes 31 are provided on the rock slope 1 at intervals in the vertical and horizontal directions, an anchor 32 made of a metal rod is inserted into each mounting hole 31, and a mortar, an adhesive,
It is fixed with a filler 33 such as resin. A ring-shaped locking portion is formed at the front end of the anchor 32.

After the grid frame fence 5 is installed, the grid frame fence 5 is connected to the anchor 32 by the connecting member 34. Connecting material 34
Is an assembly, which comprises two hooks 35 made of a thick metal plate and a wire 36 formed of a metal stranded wire connecting the hooks 35. If each hook 35 is hooked on the locking portion between the grid frame fence 5 and the anchor 32, the grid frame fence 5 can be easily connected to the anchor 32. The connection point of the lattice frame fence 5 may be the front wall part 6 or the bottom wall part 7, but a horizontal reinforcing bar at the lower part of the front wall part 6 or a horizontal reinforcing bar of the bottom wall part 7 is appropriate. It is preferable to have at least two places.

According to the present embodiment, in addition to the effect of the first embodiment, even if the depth of the embankment material 9 is reduced to 2000 mm or less (for example, about 500 mm), the grid frame connected to the anchor 32 by the connection material 34. The fence 5 holds the embankment material 9 to prevent its collapse. Therefore, even if there is a gutter, a road, a land boundary, etc. just in front of the lower end of the rock slope 1, and the width of the land 2 is narrow, construction can be easily performed.

Further, by setting the inclination angle of the front wall portion 6 as described above, the inclination angle of the front wall portion 6 can be reduced on the lower side where the earth pressure is large, and the force withstanding the earth pressure of the embankment material 9 can be reduced. Can be secured. In addition, the inclination angle of the front wall portion 6 can be increased as the earth pressure becomes lower, so that the upper shoulder (not shown) moves forward, and the effective area of the top end surface can be increased.

<< Third Embodiment >> Next, FIG. 7 shows a third embodiment applied to the protection structure of the wall surface of the concrete retaining wall block, and differs from the first embodiment only in the following points. . The structure of the corner is the same as in the first embodiment.

The wall surface 41 of the concrete retaining wall block 40
Is a steep slope of about 90 degrees. A large number of mounting holes 42 are formed in the wall surface 41, the anchor 43 is inserted into the mounting hole 42, and the filler 43 is filled to fix the anchor 43. A mounting member 45 extending vertically along the wall surface 41 is attached to a locking portion formed at the front end of the anchor 43. Connect both ends of the connecting member 46 made of metal wire to the grid frame fence 5
And the attachment material 45, thereby connecting the lattice frame fence 5 to the anchor 43.

It should be noted that the present invention is not limited to the above-described embodiment, and can be embodied with appropriate modifications without departing from the spirit of the invention.

(1) In each embodiment, the end of the reinforcing member is extended and fixed to a surface to be protected such as a slope or a wall surface. FIG. 8 shows a modification in which the ends of the nonwoven fabric 3a and the geogrid 3b are extended and fixed to the rock slope 1 with the holding plate 24 and the pile 25 in the first embodiment. The reinforcing member in this case has an effect of strongly preventing the lattice frame fence 5 from moving, similarly to the anchors 32 and 43.

(2) The bottom wall 7 of the grid frame fence 5 is
a or the geogrid 3b by connecting with a wire or the like.

(3) In each embodiment, the greening sheet is omitted.

(4) In each of the embodiments, the space between the lattice frame fence and the surface to be protected such as a slope or a wall is filled with rocks such as crushed rocks and gravel.

(5) In each embodiment, instead of the spray layer, a sandbag containing soil, seeds and the like in a bag is used.

(6) In each embodiment, the lower grid frame fence 5
The front wall part 6 of the upper lattice frame fence 5 is arranged so as to overlap the rear side with respect to the front wall part 6 of FIG. 9, but as shown in FIG.
Upper grid frame fence 5 against front wall 6 of lower grid frame fence 5
Can be arranged such that the front wall portion 6 of the front side overlaps the front side. In FIG. 9, illustration of each part other than the lattice frame fence 5 is omitted for convenience.

(7) As shown by the thick line in FIG. 10, a part of the reinforcing bar constituting the lattice frame fence 5 (for example, a part requiring particularly high strength) should be thicker than the other reinforcing bars. Thus, it is possible to prevent a phenomenon in which a part of the reinforcing bar is bent and deformed to the front side by the pressure of the filler.

[0048]

As described in detail above, according to the protection structure for the slopes and walls of the present invention, a grid frame fence having excellent points such as being able to be constructed even on steep slopes and having good construction efficiency is used. In protection structures such as slopes and wall surfaces, it is possible to reduce the amount of geotextile used as a reinforcing member for mooring the grid frame fence to the embankment material, thereby reducing construction costs. This provides an excellent effect that the strength and drainage function of the entire protection structure can be obtained which is close to the use of the water.
