Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a concrete product which simultaneously achieves both the disaster prevention function of a structure and the landscape maintenance of a natural environment by integrating slope protection by a law block and greenery concrete block in the law frame. It is a thing.

[0002]

[Prior art]

 Conventionally, a legal frame block or a tension block has been generally used for protecting the slope of the cut embankment upper part when constructing a river embankment, a new road, or building a residential land. This is a construction method in which a block is filled in the frame to stabilize the slope. However, as the idea of placing importance on the landscape of the natural environment has become established as a social need in recent years, the diversity and importance of the slope revegetation method is also increasing. In the case of greening within the frame of this legal frame block, conventionally, seed spraying is carried out together with the culture soil instead of covering the interstitial block, or the culture soil is pre-filled in the frame and the ground cover plants are grown and greened by the tension grass etc. The method was generally adopted.

[0003]

[Problems to be solved by the device]

 However, with the above-mentioned greening method, surface rainwater and flooded plants cause the planted soil to collapse and be washed away by flooding at the same time. There are problems that are not the best greening measures. Therefore, in the present invention, in order to solve the above problems, by integrally forming a concrete block as a basis of turfgrass and a culture soil, a strong green surface that is not easily destroyed even by a natural disaster is secured. The purpose is to provide concrete products that also have the original slope protection function.

[0004]

[Means for Solving the Problems]

 The above object of the present invention can be achieved by a concrete product having the following configuration. The point is that the slope block for slope protection and the block block installed inside the block are integrated, and the block block is made of a porous concrete with high water permeability and air permeability. Molded and filled in the voids in the porous concrete with a culture soil containing a sufficient amount of water retaining material and fertilizer to facilitate the growth of ground cover plants such as turf. It is a frame block. In addition, the upper and lower surfaces of the stuffing block section are covered with culture soil to promote the germination of ground cover plants such as grass and the rooting of turfgrass, and the stuffing block section is provided with many perforations. It is what

[0005]

[Action]

 The present invention achieves protection of slopes and conservation of the natural environment at the same time by integrally molding a three-layer structure interlocking block for plant growth inside the slope frame block for protection of slopes. In addition, the interlocking block made of porous concrete within the legal framework resists natural disasters such as heavy rains and floods, and has the function of minimizing slope damage.

【Example】

 Hereinafter, the tension frame block according to the present invention will be described in detail with reference to the drawings showing an embodiment thereof. As shown in FIG. 1 and FIG. 2, the method frame part 1 is integrally formed without a four-round joint, and the connecting bar 3 which also functions as a reinforcement of the interlock block part 2 made of porous concrete is diagonally formed. Then, several centimeters at both ends are projected from the corners of the method frame portion 1 and used for connection with the adjacent method frame. Further, the concrete of the method frame portion 1 is formed by an immediate demolding superhard kneading concrete or a normal casting concrete.

Next, an upper culture soil 4 and a lower culture soil 5 are covered on the upper surface and the lower surface of the stuffing block portion 2, respectively, and a wire mesh 6 is provided on the lower culture soil 5 surface. Further, the thickness of the filling block portion 2 made of porous concrete is selected in the range of 4 to 6 cm in consideration of the length of the turf. In addition, the voids inside the porous concrete are filled with culture soil containing a water retaining material and fertilizer so that the growth of the lawn roots can be facilitated.

Further, as shown in FIG. 3, the above-mentioned upper culture soil 4 promotes germination in the case of sowing, and 0.5-2. Within the thickness range of 0 cm, the above-mentioned lower culture soil 5 receives the above-mentioned lower culture soil a through the perforated portion 7 and the void portion 8 perforated in the stuffing block portion 2, and the grass root is cut on the ground cut surface or the embankment surface. It has the role of fixing water and supplying nutrients and water from the natural ground.

FIG. 4 is an enlarged explanatory view of the interior packing block portion 2 made of porous concrete, in which the aggregate 9 is fixed by the cement paste 10 and is placed between the aggregates 9. Thus, the void portion 8 is formed. The voids 8 are divided into voids that are open to the outside and voids that are closed, and the void ratio is the degree of sizing of the aggregate, the shape of each aggregate, the degree of packing, and the cement pellet that is the binder. -Variable in a wide range depending on the amount of strike or the water-cement ratio.

The compounding ratio and compounding ratio of the instant demolding concrete of the above-mentioned method frame 1 are shown below. The maximum particle size of the aggregate was 13 mm, and the compounding ratio was 11% by weight of cement, 4% by weight of water, 63% by weight of sand, and 22% by weight of coarse aggregate. The mixing ratio of water and cement W / C: 40.0% The mixing ratio of sand and aggregate (sand + coarse aggregate) S / a: 74.2%. Next, the compounding ratio and the compounding ratio of the porous concrete of the padding block 2 are shown below. The particle size range of the sized aggregate is 5 to 13 mm, cement 13.7% by weight, water 3.8% by weight, coarse aggregate 82.4% by weight, admixture (high performance water reducing agent) 0.1% by weight The blending ratio of The mixing ratio of water and cement W / C: 28.0% The mixing ratio of sand and aggregate (sand + coarse aggregate) S / a: 0%.

According to the above blending ratios and blending ratios, the compressive strength of the concrete for the frame portion (after 2 weeks) is 324 Kgf / cm ² , the compressive strength of the porous concrete (after 2 weeks) is 97 Kgf / cm ² and The porosity of the porous concrete was 24.4%. Further, an example of the mixture of the culture soil filled in the porous concrete voids is shown below. Masago soil type soil 99.0% Water retaining material (polyvinyl alcohol type) 0.5% Compound fertilizer 0.5%

A combination example of the upper culture soil and the lower culture soil is shown below. Culture soil 98.0% Fixing material 0.5% Water 1.3% Compound fertilizer 0.2% The above-mentioned concrete-clad block made of composite material of culture soil can achieve the intended purpose. It has become possible.
