JP5108744B2 - Greening road surface forming block and greening road surface on which the block is laid - Google Patents

Description

  The present invention mainly includes a road for forming a road surface for vehicles such as a road, a parking lot, and the like that can be planted by laying turf, plants, and the like, and a green road surface on which the block is laid. About.

  As a concrete block for the purpose of road greening, for example, a plant is vegetated on the surface of a charcoal-containing concrete body obtained by kneading and hardening water in which 100 parts by weight of cement is mixed with 10 parts by weight or more of wood carbide. There is a greening block in which a plurality of recesses for receiving soil or a plurality of holes penetrating vertically are provided, and the soil is planted by placing the soil in the recesses or holes. By arranging a large number of such greening blocks on the sidewalk, garden, outdoor passage surface, it can be used as a greening road surface (see Patent Document 1).

  Such a greening block can be said to be a useful greening block in that the charcoal-containing concrete body is made of porous concrete, so that the effect of promoting vegetation is high and it can be used in places where drainage is necessary.

  However, the greening area of the greening block (the ratio of the place where the soil for plant cultivation is inserted to the laying area of the concrete block) has a certain limit. That is, when the greening block is laid on the road surface on which the automobile actually passes or parks, the proportion of concrete inevitably decreases when the greening ratio is increased, so it can withstand the weight of the automobile passing through the upper surface. And the weight of the car will cause the block to crack or break. Accordingly, when the vehicle is used on a road surface on which an automobile, particularly a heavy vehicle (truck, trailer, etc.) passes or is parked, the area of greenable area must be lowered. In this case, the area to be greened becomes narrow, and the original purpose cannot be achieved. Actually, the inventors conducted various experiments and the like, and when a block was produced with a conventional greening block so that a truck with a weight of about 5 t could pass through, about 30% was the limit. It was.

  Moreover, if the site | part which makes a plant vegetate like the greening block of patent document 1 surrounds the circumference | surroundings like a recessed part and a through-hole, the problem that the root spread of a turf will be prevented and a growth will be prevented. there were.

JP 2002-191235 A

  The present invention has been devised in view of the above problems, and provides a green road surface forming block that can be laid in a place where an automobile passes or is parked to secure a wide greenable area. It is in.

  Another object of the present invention is to provide a green road surface forming block that is not easily damaged even if a truck that is a heavy vehicle passes or parks.

  Furthermore, this invention is providing the road surface using the block for greening road surface formation which can reduce the damage to the planted grass even if a motor vehicle, a truck, etc. pass.

  Furthermore, it is providing the greening road surface formation block which can form widely the growth area | region which can extend a root below and the side of the soil for plant cultivation.

  In order to solve the problems as described above, the means taken by the present invention is one or two or more connecting two or more concrete blocks and the concrete blocks while forming a gap for burying plant growing soil. And a greening road surface forming block characterized by comprising a connecting rod.

  That is, by connecting a plurality of concrete blocks with a connecting rod, the strain of the concrete block generated by the weight of the automobile is reduced, and the strain can be absorbed using the elasticity of the connecting rod. . Further, the connecting rod has a function of preventing individual concrete blocks from sinking or moving.

  Furthermore, the said structure WHEREIN: The upper surface of the said concrete block is a rectangle, It is characterized by the above-mentioned. Furthermore, the rectangle on the upper surface of the concrete block has a short side of 100 mm to 120 mm and a long side of 840 mm to 880 mm.

  Further, four concrete blocks are arranged in parallel in the short direction, and the connecting rods connect all the concrete blocks, and further, gaps between the upper surfaces of the adjacent concrete blocks are characterized. The width is 110 to 170 mm. Moreover, when the four corners of the concrete block are connected, a square shape is obtained.

  Furthermore, the means which this invention took is the said soil for plant cultivation embed | buried in the clearance gap between the said concrete blocks in the greening road surface which laid the greening road surface formation block of any one of Claim 1 to 6 The surface of is a greening road surface characterized by being 1 to 15 mm below the upper surface of the concrete block.

  Further, the means adopted by the present invention is a greening road surface characterized in that the greenable area is 50% to 65% with respect to the block laying area.

  The effects obtained by adopting the above means are as follows.

  According to the concrete block for greening road surface formation according to the present invention, a road surface having a sufficient stable structure against the weight of a heavy vehicle and having little damage to the turf is secured while ensuring a sufficient area for greening. can do.

  The best mode for carrying out the “greening road surface forming block” of the present invention will be described.

  The green road surface forming block according to the present invention includes two or more concrete blocks separated from each other and a connecting rod. Two or more concrete blocks are connected by a connecting rod with a gap from the upper surface to the lower surface. A part of this gap forms an embedded part for embedding plant growing soil. Since there is a gap from the upper surface to the lower surface, the water soaked in the soil can easily penetrate into the basement. The gap between the concrete blocks does not necessarily need to be provided with a constant width. For example, the concrete block may be provided with a slope on the side surface so as to have a portion whose width becomes narrower downward from the upper surface opening. By adopting such a configuration, a large greenable area can be secured on the upper surface, while the lower part of the concrete block can have a divergent shape, so that a stable structure can be obtained. Therefore, the greening road surface forming block can be laid without placing mortar for installation or laying concrete. Further, for example, as shown in FIG. 4, the inclination may be inclined by providing two or more steps. If slopes are provided in two or more stages, a buried area for plant growing soil can be formed in a substantially U shape, and a large area for growing grass roots can be taken, and the lower part can be broadened to the bottom. Can do. The narrowest part of the gap between the concrete blocks is preferably set to 20 mm to 40 mm. Water permeability can be secured while preventing the soil for plant growth from sinking below the concrete block. In addition, in order to reinforce the strength of the concrete block, it is possible to appropriately perform reinforced concrete by embedding a reinforcing bar or the like inside.

  In addition, since the green road surface forming blocks are connected by a connecting rod, even when a vehicle is placed on one concrete block after laying, the force due to the sinking of the concrete block is adjacent due to the elasticity of this connecting rod. It is possible to reduce the transmission to the concrete block. Therefore, the concrete block can be prevented from being broken by strain. More specifically, when a relatively large flat concrete block made of a single piece of concrete is used, for example, when a heavy heavy vehicle is placed on a part of the concrete block, the weight is only applied to a part of the concrete block. May not be able to withstand the strain caused by the force and may crack. However, since the greening road surface forming block of the present invention is made by connecting two or more relatively small concrete blocks with a connecting rod, even if a heavy vehicle is placed on any concrete block, the connecting rod is not The bending and application of force to the adjacent concrete blocks are alleviated, and the strain related to the individual concrete blocks is reduced to prevent breakage. Accordingly, the connecting rod is selected to have a strength that does not cause damage due to strain generated when a heavy vehicle is placed on one concrete block, and an elasticity that can bend and absorb the strain. A reinforcing bar is preferably used as the connecting rod.

  Even if the greening road surface forming block of the present invention is a relatively small concrete block, since a plurality of concrete blocks are connected and heavy, movement in the lateral direction can be suppressed by a connecting rod. Further, for example, even a concrete block once placed on a heavy vehicle is likely to return to the initial position again due to the elasticity of the connecting member. Therefore, the green road surface forming block once laid does not easily move up, down, left and right.

  As the individual concrete block used here, a concrete block whose upper surface is formed in a quadrangle may be used. Preferably, it is good to form in the rectangle whose short side is 100 mm-120 mm, and long side is 840 mm-880 mm. For example, as shown in FIG. 1, the width (short side) of the concrete block is shortened by connecting blocks with a rectangular upper surface arranged in parallel in the short direction, so the vehicle moves in the direction of the arrow. In this case, even if the vehicle is placed on a part of the concrete blocks, there will be a connecting member in the vicinity, and the connecting rod will easily eliminate the strain. Therefore, when laying concrete blocks, it is preferable to lay so that the vehicle passes in the direction of the arrow. The entire concrete block may be formed in a substantially rectangular parallelepiped. In addition, as shown in FIG. 1, a substantially rectangular parallelepiped includes what has a side surface which forms a slope, and a width | variety expands or narrows, and includes what is a rectangular parallelepiped shape as a whole.

  As for the size (outermost dimension) of the concrete block, a concrete block having a width of 210 to 230 mm, a length of 960 to 980 mm, and a height of about 190 to 210 mm may be used. If it is such a size, it can be set as the structure which can fully endure the weight of a heavy vehicle. Moreover, for example, when it is continuously installed in the width direction as in the construction example shown in FIG. Moreover, it becomes the width | variety which can fully mount two tire widths employ | adopted frequently with a heavy vehicle.

  Although the number which connects the said concrete block is not limited, It is preferable to connect 4 in parallel in a transversal direction. When connecting four concrete blocks, individual blocks may be connected by separate connecting rods, but all concrete blocks can be connected by one connecting rod so that the connecting members pass through the two concrete blocks. Should be connected. By connecting the four, it is possible to reduce the number of times the greening blocks are arranged when laying, and the laying becomes easy. Furthermore, the width of the gap between the upper surfaces of the adjacent concrete blocks is preferably 110 to 170 mm. If the width of the gap is set, by further adopting a means of burying the soil in the buried portion by reducing the soil by about 1 to 15 mm, the tire does not fall into the soil portion even when the tire of the automobile enters this gap. It can prevent crushing vegetated lawn and the like.

  The greening road surface forming block is formed to be a quadrangle as a whole. For example, it is preferable that four concrete blocks are formed so as to form a square when the four corners are connected. By making it square, it can be installed on the road surface in a lattice shape, so that it becomes easy to arrange and excellent in aesthetics. In general, a concrete block is hung at four places by hooks and transported, and the stability in such a case is excellent.

  Further, by applying a photocatalyst or the like on the upper surface of the block, it is possible to remove environmental pollutants such as NOx discharged from automobile exhaust gas. By adopting such a configuration, it is possible to provide a green road surface forming block that not only contributes to road greening but also contributes to the preservation of the global environment.

  The greening road surface forming block produced as described above is generally constructed after excavating the planned laying site, laying the foundation crushed stone, and then laying the greening road surface forming block and burying the plant growing soil in the buried part. Lay. At this time, the green road surface forming block according to the present invention is a divergent concrete block, and since a plurality of blocks are connected with connecting rods and are stable blocks having a weight, installation mortar or concrete is not necessarily provided. There is no need to cast. Furthermore, after laying a sheet of woven fabric, non-woven fabric or mesh on the ground crushed stone, sand may be laid to impart flatness and cushioning properties, and then a green road surface forming block may be laid. The reason why the sheet of woven fabric, non-woven fabric or mesh is used is to prevent water from penetrating but laying sand and soil from falling downward.

  The best mode for carrying out the “greening road surface forming block” of the present invention will be described below with reference to the drawings. Of course, the following examples only show preferred examples of the present invention, and the technical scope of the present invention is not limited to the following examples.

  1 is a plan view and a front view of a greening road surface forming block 100 according to a first embodiment, and FIG. 2 is a side view thereof. FIG. 3 is a perspective view of the green road surface forming block 100 according to the first embodiment.

  The green road surface forming block 100 according to the first embodiment includes four concrete blocks 10 and a connecting rod 20 that connects the four concrete blocks 10.

    The individual concrete blocks 10a, 10b, 10c, and 10d are substantially rectangular parallelepiped as a whole. The concrete shape will be described in detail. The upper surface 15 of the concrete block 10 has a rectangular shape of 110 mm × 860 mm, and as shown in the front view of FIG. 1, the first that gradually spreads outward from the plane downward. A side slope 11 is formed, and a second side slope 12 that forms a steeper slope than the first side slope 11 from below 10 mm below the first side slope 11, and a third side slope 13 that forms a gentle slope from the second side slope 12. Further, a fourth side slope 14 that is inclined inward from the third side slope 13 is formed. When viewed from the front as a whole, it has a shape in which four trapezoids are stacked, and a position having a height of about one-third of the total height swells outward most. The widest portion A is set to 970 mm. Similarly, when viewed from the side, a shape in which four trapezoids are stacked as shown in FIG. 2 is formed, and the widest portion B is set to 220 mm. In each concrete block 10, three deformed reinforcing bars 21 are embedded along the longitudinal direction to improve the strength.

  On the other hand, the connecting member 20 is made of a reinforced anticorrosive rebar by galvanizing, and penetrates through the two concrete blocks 10b and 10c, and is embedded in the two outer concrete blocks 10a and 10d. Two concrete blocks 10a, 10b, 10c, 10d are connected. The gap between each concrete block is in a state where the reinforcing bar is exposed. The gap between the upper surfaces is 140 mm, and the narrowest portion D is 30 mm. Therefore, the buried portion α in which the soil for plant cultivation such as lawn and grass is buried is formed so that the upper part is wider and the lower part is narrower. By setting it as this structure, only the water can permeate | transmit below, without the soil embed | buried in the burying part (alpha) falling downward.

  The entire greening road surface forming block is connected so as to form a square of 970 mm (A) when viewed from a plane (see FIG. 3).

  The greening road surface forming block 100 manufactured in this way is first laid on the planned greening road surface formation site where the basic crushed stone 30 is laid, and then flattened by sand 32, and then the greening road surface forming block 100 is formed. The plant-growing soil 33 is buried so that both the upper surface 15 and the first side oblique portion 11 are exposed in the buried portion α. Then, by planting a plant 34 such as turf on the plant growing soil 33, a green road surface is formed (see FIG. 4). At this time, as shown in FIG. 5, the gaps (e, f) of 30 mm in both the vertical and horizontal directions are laid in a lattice shape. By arranging the gaps of 30 mm apart, the gaps (e, f) between adjacent greening road surface forming blocks 100 have the same width as the gaps (g) between the concrete blocks. Moreover, all the widths (i, j) between the concrete block upper surfaces exposed on the surface can be the same width. Further, since the green road surface forming block 100 according to the first embodiment is manufactured to be a 970 mm square, it has a form in which 1000 mm squares are arranged in a grid. For example, as shown in FIG. 6 which shows a state where a parking lot is manufactured, if three laid green road surface forming blocks 100 of this size are laid side by side in the horizontal direction, the heavy vehicle tires are just on the green road surfaces on both sides. It will be located near the center of the forming block and will be the optimal size for use in heavy vehicle parking lots and the like. Of course, the laying state of FIG. 6 is only an example, and is not limited to this construction state.

  Since the plant-growing soil 33 buried in the greening road surface forming block 100 laid in this way is buried so as to expose the first side bevel 11 as described above, it is more than the upper surface of the concrete block 10. The soil surface will be located 10 mm below. Since such a configuration is adopted and the distance between the upper surfaces is set to 140 mm, even if the vehicle passes as shown in FIG. 7, the first inclined portion 11 prevents the tire from falling and prevents the lawn from being crushed directly. Damage to the lawn due to traffic can be minimized.

  Even if a heavy vehicle passes through, the greening road surface is connected to the adjacent concrete block 10b with a reinforcing bar even if it is placed on a part of the concrete block 10a as shown in FIG. 8, for example. Even if the whole sinks somewhat, it is possible to prevent the strain from being transmitted to the adjacent concrete block 10b and to prevent the block from being damaged. When the tire moves as shown in FIG. 9, the depressed concrete block 10 a is returned to the initial position by the elastic force of the connecting member 20. By connecting the concrete block 10 with the connecting member 20 in this manner, the concrete block 10 is prevented from being damaged and has an effect of preventing movement from the initial position. Note that FIGS. 8 and 9 are exaggerated for illustrative purposes only, and there is actually no sinking as shown in the drawings.

  As described above, when the green road surface forming block according to the present embodiment is used, the area that can be greened is the main green road surface even though a heavy vehicle or the like passes through without forming damage. It is possible to secure a wide greening area of about 62% or more with respect to the area where the forming blocks are laid.

  In addition, the said Example is only an optimal Example to the last, The size of a block etc. can be suitably changed according to the place to lay, the vehicle to pass, etc. Further, the shape of the block is not limited to the form of the present embodiment as long as it has a substantially rectangular parallelepiped shape. Further, the connecting rod does not need to be a reinforcing bar, and plastic or the like may be used as long as the material has a certain degree of elasticity and hardness.

  The green road surface forming block according to the present invention may be used when forming a green road surface in which a parking lot, a road, or the like is green.
