Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope block which protects slopes such as river banks and enables plants to grow.

[0002]

2. Description of the Related Art In general, revetment work for protecting the dike slopes of rivers involves leveling the dike slopes, placing a formwork and placing concrete, or laying concrete blocks on the slope. Is done by doing. In such a revetment work, since the slope is constructed in a state where concrete is tensioned, the natural environment and landscape are lost, and it is difficult to protect the natural ecosystem and natural landscape.

On the other hand, conventionally, a revetment block designed so that insects such as fireflies and plants can grow and grow has been proposed (Japanese Utility Model Publication No. 62-148619 and Japanese Utility Model Publication No. 63-28971). ). In these conventional revetment blocks, there is a hollow portion for inhabiting and growing insects and vegetation, and an insect entrance and a water hole are connected to this hollow portion.

[0004]

However, in such a conventional revetment block, vegetation can be grown only in a limited part within the cavity of the block, and relatively large vegetation can be used. It is not suitable for growing, and the exposed part of the concrete surface outside the cavity remains in a state where plants can not grow, this can not create a sufficient natural environment and landscape, and these conventional revetment blocks Since it has a structure that is applied to a steep slope, it is not suitable for construction on a gentle slope, and furthermore, a water passage hole for draining water must be provided in the cavity. However, the block itself has a complicated structure, and it takes time to manufacture.

The present invention has been made in view of the above circumstances, and an object thereof is to protect an slope such as a river embankment and an environment where plants can grow at any slope. The purpose is to provide a slope block with a simple structure that can be made to grow plants all over and create a sufficient natural environment and landscape.

[0006]

To solve the above object, according to an aspect of the means to which the present invention is taken, when described using the reference numerals used in the drawings, slope block as claimed in claim 1, wherein the "small
With a lower layer portion containing aggregate and an upper layer portion containing large aggregate,
The aggregates 12 are bonded to each other with a gap, and seeds are placed in the gap.
The slope block 10 "is characterized in that it is filled with a filling material 14 in which child, fertilizer and the like are mixed .

[0007]

[0008]

[0009] The slope block includes not only individual blocks produced in a factory in advance and laid on the slope such as an embankment, but also those formed on the slope by construction on site. I'm out.

[0010]

In the slope block 10 according to claim 1,
Unlike conventional concrete blocks, for example, Fig. 1
And, as shown in FIG. 2, the upper layer portion that constitutes the block 10.
Contains granular material 11 with a large particle size as an aggregate,
Granules 11 that are aggregates, including granules 11 with a small particle size
Since the gap 12 is provided between the particle size of fine soil and seed empty gap 12, those like paste mixed with fertilizers can be filled and held, also the water 50 through the air gap 12 It is replenished and the plant 30 can be grown in the block. The voids 12 allow the plant 30 to grow roots inside the block 10 and outside the block 10. In addition, the slope block 10 does not need to be provided with a water passage, unlike a conventional concrete block, and the void 12 serves as a passage for water to perform the same function as the water passage, so that water is not supplied to the outside. Water can be supplied to the plant 30 while flowing out.

[0011]

Further, as shown in FIG.
Since the filling material 14 in which seeds, fertilizers, etc. are mixed is previously filled in the void 12, the plant 30 is naturally grown only by laying it on the slope.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the drawings. 1, 4, and 5 are cross-sectional views of an example of the slope block according to claim 1 in use, and FIG. 2 is a partial cross-section showing an example of the slope block according to claim 2. It is a figure and Drawing 3 is a partial sectional view showing one example of a slope block according to claim 3.

1 to 3, the slope block 10 is shown.
The granular material 11 is used as an aggregate, and the granular material 11 forms voids 12.
It is preferable to use the one having a range of mmφ to 150 mmφ. As the granular material 11, gravel, wood waste, pellet-shaped plastic, or the like can be used alone or as a mixture thereof. Further, so-called waste such as rubber pieces or concrete crushed pieces may be used for the granular material 11. This makes it possible to effectively use the waste. The form of the granular material 11 may be spherical or polygonal. Further, the structure of the granular material 11 itself may be solid or may be porous such as pumice. Further, the aggregate is not limited to the granular material 11, and as shown in FIG. 4, a fiber bundle 16 in which fibers such as chemically synthesized fibers are bundled so as to generate a capillary phenomenon may be used.

The slope block 10 is formed into a predetermined shape after the granular material 11 or the fiber bundle 16 is used as an aggregate and the binder such as a resin adhesive such as cement, tar, pitch or urethane is kneaded with the aggregate. It is made by molding or in-situ casting. In addition, at the time of manufacturing, for reinforcement,
A reinforcing material 13 such as a wire or a net is laid vertically and horizontally in the block. The reinforcing material 13 is appropriately applied not only to the size of the block 10 but also to the strength of the block 10 itself depending on the size and type of the granular material 11 and the fiber bundle 16 used, the type of binder, and the like. . When laying and constructing the slope block 10 on site, the reinforcing material 1 is used so that the adjacent blocks 10 can be connected to each other.
3 may be provided, and the slope block 10 integrated on the slope can be formed by the joint of the reinforcing material 13.

The binder is used to bond the aggregates to each other. However, the binder is in a liquid state because the particles 11 and the particles 11 or the fiber bundles 16 are bonded to each other with a gap 12 left therebetween. In the case of kneading with the granular material 11 or the fiber bundle 16, a material having high fluidity, hardening relatively quickly, and capable of maintaining high strength is preferable. Alternatively, the aggregates may be joined to each other while positively feeding air so that the voids 12 are formed during kneading. Alternatively, the aggregate and the binder may be kneaded and then put into a mold from a high place, so that the aggregate is separated during falling or sliding, and a gap is left to cure and bond. or,
In order to bond the aggregates to each other leaving the voids 12, a liquid binder is applied to the surface of the aggregates in advance,
The liquid materials 11 may be joined together. When the binder is a thermal adhesive, prepare an adhesive layer with a binder adhesive layer on the surface of the aggregate, put the aggregate in a mold and heat it to bond the aggregates together. May be. In order to compact the slope block 10 to be manufactured, when the binder is cement, a method of vibrating the mold or a method of compression may be used.

The upper layer contains granular material 11 having a large particle size,
In the case of the embodiment shown in FIG. 2 in which the lower layer portion includes the granular material 11 having a small particle diameter, the granular material 11 having different particle diameters can be individually laminated. When finishing several layers in the mold, the particles 11 can be produced by putting the particles 11 in the order of the grain size of the layer to be produced. The number of layers may be two, three, or more. The material of the granular material 11 may be the same or different.

In the slope block 10 having the filling material 14 in which seeds, fertilizers, etc. are mixed in the voids 12 as in the embodiment shown in FIG. 3, the filling material 14 is provided in the entire block. Alternatively, the case where the filler 14 is partially provided may be used. As the filling material 14, seeds, a mixture of fertilizer and soil, or the like is used. This slope block 10 can be prepared by filling the space 12 with a paste-like filling material 14 after the slope block 10 shown in FIG. 1 or FIG. In that case, for filling, the block 10 is dipped in the solution of the paste-like filling material 14, the paste-like filling material 14 is poured over the block 10, or pressure injection or vibration injection is performed. Further, it can be carried out by a method of injecting by utilizing centrifugal force.

When such a slope block 10 is used, it can be laid or constructed on the slope 40 as shown in FIG. 6 to protect the embankment slope 40. in this case,
The lower part of the block 10, which is an L-shaped soil retaining member, may be an ordinary concrete body in order to maintain the strength against earth pressure. Then, as shown in FIG. 7, a mixture of seeds, fertilizers, soil, and the like in a paste form is permeated and held in the voids 12 of the slope block 10 to grow the plant 30. In addition, at the site, the paste-like filling material 14
In addition to the method of infiltrating into the block 10, seeds or seed-mixed soil 15 may be sprayed onto the slope of the block 10 and held in the block 10 as shown in FIG. It should be noted that the slope block 10 formed on the sloped slope 40 may be provided with a protrusion 10a that prevents slipping when walking. Further, as shown in FIG. 1, a recess 17 may be provided in the slope block 10 so as to penetrate therethrough so that a relatively large tree 31 can grow therein. The slope block 10 according to the present invention is used for a dike slope,
It can also be used on slopes such as mountain cut-off slopes.
