Description

  The present invention relates to an artificial turf pavement used for pavement such as walking paths. More specifically, the present invention relates to an artificial turf pavement that creates a natural texture using artificial turf and soil-based materials that are suitable as a walking path and have an excellent green space effect visually. The present invention also relates to an artificial grass pavement surface and a pavement method using the artificial grass pavement.

  Conventionally, for the purpose of improving drainage, preventing weed reproduction, landscape maintenance, and the like, earth-based pavement materials are known as pavement materials such as walking paths (for example, Patent Document 1). The earth-based pavement material (self-hardening earth-based pavement material) utilizing the property (self-hardening) that is hardened by addition of moisture is generally used. The self-hardening pavement can be applied to the surface to be paved, ground with a dragonfly or a rake, and then hardened by watering to provide a paved surface easily.

  On the other hand, artificial turf is provided as one that provides an excellent green landscape (for example, Patent Document 2). In addition, for the purpose of improving workability and elasticity of an artificial turf for an athletic field, an artificial turf pile filled with granular materials such as sand and rubber chips has been proposed (for example, Patent Document 3).

JP 2002-371504 A Japanese Patent Laid-Open No. 3-119212 JP 2001-254310 A

Self-hardening earth-based paving materials are generally granular, have excellent handleability, and are easy to construct, so they have a wide range of applications. However, on the other hand, when a wide area is constructed, there is a problem that the hardened surface gives an inorganic and monotonous impression because it is a soil-based material, lacks warmth, and damages the landscape depending on the application site.
Moreover, since the surface has hardened | cured naturally, the planting to a construction surface was very difficult and there also existed the subject that the improvement of the landscape by a plant was substantially impossible.

  Artificial grass, on the other hand, is usually fixed to an asphalt or concrete ground with an adhesive or the like. However, there is a problem such as displacement and peeling of the artificial grass fixed over time, and the maintenance is very large. There is a problem of requiring a lot of labor.

  Further, even if the artificial turf piles are filled with granular materials such as sand and rubber chips, they are not sufficient to prevent misalignment and peeling, and there is also a problem of sand and rubber outflow. Moreover, since the construction surface is rich in elasticity, it is suitable as an athletic field, but is not suitable for a walking path. Furthermore, the function of suppressing the rise in surface temperature under hot weather is not sufficient, and it is difficult to say that this is also suitable for pavement such as walking paths.

  The present invention solves the above-mentioned conventional problems, is superior in workability, landscape and its long-term sustainability, and further has an excellent effect of suppressing the rise in surface temperature, and is suitable for pavement such as walking paths. The issue is to provide.

  In order to solve the above-mentioned problems, the present inventor conducted the following studies on improvement of the road surface using artificial grass and a self-hardening earth-based pavement material.

  If artificial turf bodies with piles closely arranged in a line, such as long pile artificial turf laid on a pavement surface, are sprayed with self-hardening earth-based pavement, piles are formed by granular pavement. It will fall down and the finished pavement will not look good after watering and curing. When the self-hardening earth-based pavement material is cured while including a pile that has fallen in this manner, the unevenness of the finished pavement surface becomes severe, cracks are likely to occur on the pavement surface, and the aesthetics are significantly impaired.

  To prevent this pile collapse, if the particle size of the self-hardening earth-based pavement material is made too fine, the pavement material will adhere to the pile, and the pile that will become the artificial turf surface will not flow down even after watering. It will be colored brown by the paving material, resulting in poor finish. In this case, there are problems in the flatness, aesthetics, and durability of the finished pavement surface, and there is also a problem of scattering of the pavement material before watering, resulting in poor workability and workability.

  Therefore, the present inventor further studied the structure of the artificial turf. Specifically, a monofilament artificial turf yarn bundle (pile) of a predetermined size is made into a relatively large lump (colony) and the distance between the colonies is controlled to an appropriate value to prevent pile collapse. The present invention has been completed by finding that it is easy to fill a self-hardening earth-based pavement material without impairing the landscape as an artificial turf, and that a finished pavement surface excellent in workability and durability can be realized. It was.

  That is, the gist of the present invention is as follows.

[ 6 ] A pile is erected on a sheet-like base material, and the pile is provided as a colony composed of an aggregate of a plurality of piles, and a plurality of the colonies are provided on the base material with a predetermined interval. This is a pavement method in which the artificial turf body formed is laid on the construction surface, and then a self-hardening earth-based pavement material is filled between the piles of the artificial turf body, and then water is sprayed to cure the pavement material. The pile has a weave of 1000 dtex or more, a thickness of 100 μm or more, and a lawn height of 30 to 60 mm, and the colony has a pile density of 15 pieces / cm ² or more and a base area of 0.5 to ⁵ cm ² . And the space | interval of adjacent colonies is 0.5 cm or more, The pavement method characterized by the above-mentioned.

According to the artificial turf pavement of the present invention, the artificial turf pile of a specific size has a specific colony structure, and in combination with a granular self-hardening earth-based pavement, the pile collapses when filling the pavement. It is possible to realize a finished pavement surface with excellent workability and workability and excellent appearance.
Moreover, it retains the high water retention characteristic of soil-based paving materials, and can easily suppress the temperature rise of the paving surface, which is a problem in the summer, by watering, and has excellent durability. It can be.
In addition, since the artificial turf can be fixed by the solidified self-hardening earth-based pavement material, the artificial turf main body is prevented from being displaced, peeled off or piled off, and the maintenance of the pavement surface can be greatly reduced.

  According to the present invention, by using a self-hardening earth-based pavement material as a filler for a specific artificial turf body, it is possible to provide a green and very beautiful landscape similar to natural turf, and self-hardening. In addition to the above-mentioned suppression of surface temperature rise by soil-based pavement materials and the effect of immobilizing artificial turf, weeds can also be used to prevent weed growth and water retention by self-hardening soil-based pavement materials. The appearance and functionality of the self-hardening earth-based pavement material can be significantly improved compared to a single pavement surface.

  The artificial turf pavement of the present invention can be used not only as a road surface improvement, but also as a block material that is individually manufactured as a block body, laid on slopes for various revetments, and further combined as an interlock. And its industrial usefulness is extremely high.

BRIEF DESCRIPTION OF THE DRAWINGS It is a schematic diagram which shows embodiment of the artificial turf pavement of this invention, Comprising: (a) A figure is sectional drawing, (b) is a plane which shows the projected area of the top part of a pile, and the area of a base part FIG. It is a perspective view which shows the example of a shape of a pile. It is a graph which shows the time-dependent change of the surface temperature of the sample in Example 2 and Comparative Examples 3-5.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1 (a), the artificial turf pavement of the present invention has an artificial turf body 4 in which a pile 2 is erected as a colony 3 made up of an assembly of a plurality of piles on a sheet-like base material. The self-hardening earth-based pavement material 5 is filled between the piles 2 and 2 (mainly the space between the colonies), and the self-hardening earth-based pavement material 5 is cured. After laying the artificial turf body 4 on the construction surface, the turf pavement surface is filled with a self-hardening earth-based pavement material 5 between the piles 2 and 2 (mainly the space between the colonies), and then sprayed with water. A pavement surface is formed by curing the self-hardening earth-based pavement material 5.

<Sheet substrate>
The sheet-like base material 1 of the artificial turf main body 4 is a base of the artificial turf main body 4, and is generally a woven fabric sheet of synthetic resin fibers such as polyethylene, polypropylene, nylon, polyethylene terephthalate, and synthetic resins thereof. A sheet | seat etc. are used and the thickness is about 0.3-3.0 mm normally.

  For the woven fabric sheet, a multifilament yarn, slit yarn, flat yarn or the like of the above synthetic resin is used, and the yarn is formed by weaving these yarns with plain weave or twill weave. Moreover, the yarn which consists of another raw material may be mixed as needed.

<Pile>
The pile 2 of the artificial turf body 4 according to the present invention is erected on the upper surface of the sheet-like substrate 1 in the form of a cut pile or a half pile.

The pile 2 is generally made of a synthetic resin, and any conventionally known material can be used. Specifically, for example, green-colored multifilament yarns and slit yarns made of various polyethylenes, various polypropylenes, various nylons, polyvinyl chloride, polyvinylidene chloride, and the like are used. Usually, from the viewpoints of softness and flexibility, those made of LDPE (low density polyethylene), LLDPE (linear low density polyethylene) or the like are preferably used.
In the present invention, it is important that the pile does not fall down due to the filling of the self-hardening earth-based pavement material. Therefore, from the viewpoint of improving the strength and rigidity, it is preferable to use a stretched pile.

  The shape of the pile 2 is also arbitrary, and in order to ensure its uprightness, the shape of the cross section perpendicular to the length direction is usually a circle, a rectangle such as a rectangle, a rhombus, a V shape, a U shape, a Y shape, an ellipse. What was shape | molded in various shapes, such as a shape, is used. 3A and 3B are perspective views showing an example of a pile shape. FIG. 3A shows a pile 2a having a circular cross section, FIG. 3B shows a pile 2b having a rectangular cross section, and FIG. 3C shows a pile 2c having a V-shaped cross section. (D) shows a pile 2d having a U-shaped cross section, and (e) shows a pile 2e having a Y-shaped cross section. In addition, one or a plurality of cores are embedded in the apex part of the V-shaped, U-shaped or Y-shaped cross section (the bottom end portion in the case of V-shaped or U-shaped) or the branched part of the Y-shaped cross section. Alternatively, one or a plurality of core members may be inserted into a hollow portion of a pile having a circular cross section, an oval shape, or a square shape.

In the present invention, the pile 2 has a weave of 1000 dtex or more, a thickness of 100 μm or more, and a lawn height of 30 to 60 mm.
Here, decitex (dTex) is a unit that defines the thickness of the fiber, and corresponds to a weight (g) of 10 km length. Moreover, the thickness of a pile means the thickness shown by "d" in a figure, for example in pile 2a-2e shown to Fig.3 (a)-(e). Moreover, the lawn height of a pile refers to the length of the pile 2 exposed from the upper surface of the sheet-like base material 1.

  If the pile 2 has a lawn height of 30 to 60 mm, a natural texture as a lawn can be created. If the turf length of the pile 2 is shorter than the above range, the self-hardening earth-based pavement material cannot be sufficiently filled, and if it is longer than the above range, it is difficult to ensure the standing property.

  Further, when the pile having a turf height of 30 to 60 mm has a weaving degree of 1000 dTex or more, preferably 2000 dTex or more and a thickness of 100 μm or more, preferably 300 μm or more, the standing property and durability are improved. On the other hand, good shape retention is exhibited. However, if the weaving degree and thickness of the pile 2 are excessively large, the texture of the artificial turf is impaired. Therefore, the weaving degree of the pile 2 is preferably 5000 dTex or less, and the thickness is 600 μm or less. It is preferable.

  The artificial turf body according to the present invention may be one in which two or more types of piles having different shapes, weaving degrees, thicknesses, turf lengths, materials, and the like are erected on a sheet-like substrate. As for the panel that forms a plurality of piles, a single colony may contain a plurality of piles. Moreover, in the pile provided in the sheet-like base material, one having a weaving degree of less than 1000 dTex may be included, but more than half of the piles constituting one colony have a weaving degree of 1000 dTex or more. It is preferable that in one colony, the average value of the weaving degree is 1000 dTex or more, particularly 2000 dTex or more.

<Colony>
In the artificial turf body 4 according to the present invention, the above-described pile 2 is erected on the sheet-like base material 1 as a colony 3 formed by a plurality of the aggregates. Here, a colony is a set of piles in which the distance between piles on the sheet-like substrate surface is not 2 mm or more, and is regarded as one colony. The colonies may be arranged regularly on the sheet-like base material 1 or may be provided in a random arrangement, but are usually arranged in a square arrangement or a Kurile arrangement in the manufacturing process of the artificial turf body. Provided in the arrangement.

The pile density of the colony 3 is 15 / cm ² or more, preferably 15 to 60 / cm ² , more preferably 20 to 50 / cm ² , and particularly preferably 25 to 50 / cm ² . If the pile density of the colony 3 is lower than 15 / cm ^2, a green space sensation sufficient as a turf surface cannot be obtained, and the appearance is inferior. However, when the pile density is too high, the filling property of the self-hardening earth-based pavement material is deteriorated.
Here, the pile density refers to the number of piles relative to the unit area (area occupied on the sheet-like substrate) of the base of the colony.
In addition, the pile density of the several colony formed on the sheet-like base material does not need to be all the same, and pile density may differ for every colony within said range. For example, colonies having a relatively high pile density and colonies having a relatively low pile density may be alternately arranged in parallel.

The area of the base of the colony 3 (hereinafter referred to as “bottom area”) is 0.5 to ⁵ cm ² , preferably 1.0 to 3.0 cm ² . If the bottom area of the colony 3 is too small, a sufficient green space sensation as a turf surface cannot be obtained, resulting in poor appearance. However, if this bottom area is too large, the colonies will become large and the “sparseness” of the pile will not be denied, and it will not be a beautiful green space, and the filling property of the self-hardening earth-based pavement will be inferior.
Note that the bottom areas of the plurality of colonies formed on the sheet-like substrate do not have to be the same, and may be different for each colony within the above range. For example, colonies having a relatively large bottom area and colonies having a relatively small bottom area may be alternately arranged in parallel.

  Moreover, in this invention, it is self-hardening earth system that a colony is a top-open shape whose projected area from the upper part of the top part of this colony exceeds 1 time of a bottom area, and is 15 times or less, especially 2-10 times. When filling the pavement material, the pavement material sprayed from above the artificial turf body does not stay on the colony but falls to the sheet-like substrate surface, which is excellent in filling property and workability, and self-hardening earth-based pavement The pile after the material is filled and hardened is preferable because it can be appropriately dispersed without forming an excessively spread or falling, and a turf surface having a good appearance can be formed.

  FIG. 1 (b) is a schematic plan view showing the projected area from above the colony crown, and in FIG. 1 (b), the circled portion indicated by the solid line corresponds to the colony vertex and is indicated by a broken line. The part of the circle corresponds to the base part. That is, in the present invention, it is preferable that the area of the region surrounded by the solid line is more than 1 time and not more than 15 times, particularly 2 to 10 times the area of the region surrounded by the broken line. Hereinafter, the ratio of the projected area from the top of the top to the bottom area of this colony is simply referred to as “the top area ratio”.

  Note that, similarly to the pile density and the bottom area, the top area ratios do not have to be the same, and colonies having different top area ratios may be mixed on the sheet-like base material.

In the present invention, the colony interval, that is, the distance between adjacent colonies of a plurality of colonies formed on the sheet-like substrate 1 is 0.5 cm or more, preferably 1 cm or more. Here, the colony interval refers to the distance between the base portions of the colonies, and is indicated by L in FIG. When this colony interval L is less than 0.5 cm, the filling property of the self-hardening earth-based pavement material is poor, and the workability during construction is inferior. However, if the colony interval is excessively large, a good turf surface with a high pile density cannot be formed. Therefore, the colony interval L is preferably 3.0 cm or less, particularly preferably 1.5 cm or less.
In addition, the colony space | interval on a sheet-like base material does not need to be the same in all the places, for example, the colony space | interval L may differ in one direction of a sheet-like base material, and the direction which crosses it.

<Manufacturing method of artificial turf body>
The method for producing the artificial turf body according to the present invention is arbitrary, but in general, a method of weaving a pile and a sheet-like substrate portion (weaving, weaving weave), a sheet or woven fabric made of resin, rubber, or the like. Examples include a method of sewing yarns (tufting, tufting). Above all, piles are hard to fall down, and piles are relatively large colonies, and they are formed at predetermined colony intervals, making it easy to fill self-hardening soil-based pavement materials without impairing the landscape as artificial turf, making them durable. For reasons such as an excellent finished paved surface, it is preferable to produce an artificial turf body with a weaving weave.
In the case of weaving weaving, piles and colonies thereof can be formed in various shapes, unlike tuft weaving in which the gauge width is fixed and the pile density is adjusted by the interval between stitches.

<Self-hardening earth-based paving material>
In the present invention, the self-hardening earth-based pavement material filled between the piles 2 and 2 of the artificial turf main body 4 as described above is hardened (solidified) at room temperature by mixing with water or the like. Also called inorganic material.

  Here, “self-hardening” indicates a penetration resistance value equivalent to that of natural soil by hardening. For example, in Japanese Patent Laid-Open No. Sho 61-257503 relating to “soil-based pavement material”, a diameter of 6. It is shown that the penetration resistance value when a 4 mm penetration needle penetrates 1 inch is 35 pounds or more. The self-hardening earth-based pavement material used in the present invention preferably has a penetration resistance value of about 50 to 130 pounds.

  There is no particular limitation on the self-hardening earth-based pavement material used in the present invention, such as recycled aggregates such as clay, sand sand, sand, foamed glass, and ground ceramics, solidified materials such as magnesium oxide and magnesium hydroxide, What mixed the pigment (color powder) as needed is mentioned.

  Such self-hardening earth-based paving materials are usually provided as granular materials. If the particle size is too small, it is easy to scatter and poor handleability, but if it is too large, it is difficult to fill between the piles. Therefore, the maximum particle size is 5 mm or less and the particle size is about 0.5 to 2 mm. That is, it is preferable that the average particle diameter is about 0.5 to 2 mm.

  Although there is no restriction | limiting in particular in the filling amount of the self-hardening earth-based pavement material 5 to the artificial turf main body 4, If it is too small, the effect of this invention by filling self-hardening earth-based pavement material can fully be acquired. If the amount is too large, the exposed length of the pile from the pavement filling surface is shortened, and the appearance as a turf surface is impaired. Therefore, a length portion of about 15 to 35 mm of the pile appears. In addition, for example, it is preferable that the filling layer thickness h of the self-hardening earth-based pavement material 5 in FIG. 1A is about 20 to 50 mm.

  In order to fill the piles 2 and 2 of the artificial turf body 4 with the self-hardening earth-based pavement material 5, after spraying a necessary amount of the self-hardening earth-based pavement material 5 from above the artificial turf body 4, rakes, dragonflies, etc. The surface should be leveled using Since the artificial turf body used in the present invention has a pile size, colony density, colony interval, and the like that are suitable for filling the self-hardening earth-based pavement 5, as described above, from above the artificial turf body 4. By simply spraying and leveling the self-hardening earth-based pavement material 5, the pile can be prevented from falling over and efficiently without piled up the self-hardening earth-based pavement material on the pile. Can be filled.

  After filling the self-hardening earth-based pavement material 5 between the piles 2 and 2, water-based materials such as water or water-based resin material are sprayed to cure the self-hardening earth-based pavement material 5. There is no restriction | limiting in particular in this watering method and the amount of water spraying, What is necessary is just to be able to provide the quantity of water required for hardening of the self-hardening earth-based pavement material 5 to be used.

  The self-hardening earth-based pavement material 5 hardened by watering prevents the position of the artificial turf body 4 from being displaced and the piles from coming off, and retains the water sprayed by its water retention, and gradually evaporates it. Thus, the effect of suppressing the rise in the surface temperature under hot weather is shown by the heat of vaporization during evaporation.

  Hereinafter, the present invention will be described more specifically with reference to examples and comparative examples.

  The artificial turf body used in the following examples and comparative examples is made of LDPE made by weaving weaving, and is made of an aggregate of cut piles having a U-shaped cross section on a 2.0 mm thick fabric sheet. A colony is formed in a square arrangement.

Moreover, the following were used as a filler for the artificial turf body.
Self-hardening earth-based pavement material: Mixing magnesium oxide and pure sand in a mass ratio of 9: 1
Granular paving material. Average particle size 2.0 mm, maximum particle size 5 mm.
Rubber chips / sand: Rubber chips made of SBR waste rubber (average particle size 3.3 m)
A mixture of m) and sand (river sand) in a mass ratio of 1.2: 1.

[Examples 1-6, Comparative Examples 1-5]
Between the piles of the artificial turf main body having the piles and coils having the specifications shown in Table 1, the filler shown in Table 1 was filled to form a paved road surface, and the evaluation was performed.

The prepared sample has an artificial turf body on the bottom surface of a resin container having a bottom surface of 310 mm × 230 mm (0.0713 m ² ) square and a wall surface having a height of 60 mm on all sides, and this is filled with a filler. It is a lawn pavement model. The amount of each filler used was such that the filling thickness of the filler was 30 mm from the bottom of the container (28 mm from the top of the base sheet).

  In Comparative Example 3, no filler was used, and in Comparative Example 5, the same evaluation was performed on an artificial turf body and an asphalt road surface without using a filler.

  In Examples 1 to 6 and Comparative Examples 1 and 2, when preparing samples, each artificial turf main body was sprayed with a self-hardening earth-based pavement material from the top surface and filled into the pile root, and then sprinkled to pave the material. Cured. In addition, since Comparative Examples 3-5 did not use the filler which does not have a filler or hardens, watering for hardening was not performed.

In this filling operation, superiority or inferiority in workability occurred.
That is, in the preparation of the samples in Examples 1 to 6 and Comparative Examples 1 and 4, when filling the filler, a rake is used, and the lawn pile is brought down while moving the rake to secure a filling path to the colony root. Thus, it was possible to easily put the filler continuously between the colonies. However, in Comparative Example 2, since the colony interval was small and the colonies were dense, it was difficult to fill with the above-described method.

  Each sample obtained was evaluated as follows, and the results are shown in Table 1.

<Appearance>
The appearance of each sample (samples after curing in Examples 1 to 6 and Comparative Examples 1 and 2) was visually observed and evaluated according to the following evaluation criteria.
A: The green is vividly covered.
○: Slightly less green, but recalls a green space sensation sufficient for the turf surface.
X: There are many soil surface parts, and the sensation as a turf surface is not recalled.
−: Not evaluated because artificial turf or filler is not used.

<Surface temperature difference>
A lamp (infrared lamp IR250WRH manufactured by Iwasaki Electric Co., Ltd.) was used as a heating source, and this was installed 70 cm above the surface (turf surface) of each sample (samples after curing in Examples 1 to 6 and Comparative Examples 1 and 2). The sample surface was heated.
When 60 minutes have passed since the start of heating, the sample whose surface temperature has risen is sprinkled with tap water equivalent to light rain with a precipitation of 0.1 mm / m ² (the amount of water sprayed on the sample is equivalent to 7.13 mL) by spraying. The surface temperature after 60 minutes from watering was measured. And the surface temperature difference (temperature rise difference) immediately after watering and 60 minutes after watering was calculated | required, and the result was shown in Table 1. Moreover, the time-dependent change of the surface temperature in Example 2 and Comparative Examples 3, 4, and 5 is shown in FIG. The smaller the surface temperature difference is, the higher the effect of suppressing the surface temperature rise is, and the surface temperature difference is preferably 10 ° C. or less.
For measuring the temperature of the sample surface, an infrared camera (infrared camera FLIR i5 manufactured by FLIR Systems Japan Co., Ltd.) was used, and the average temperature of the obtained measurement surface was obtained by the measuring device, and this average temperature was taken as the measurement temperature. .

  As is clear from Table 1, the artificial turf pavement of the present invention is excellent in appearance and excellent in the effect of suppressing the rise in surface temperature. The effect of suppressing the increase in surface temperature is that the artificial turf pavement of the present invention has water retention, and the water held in the artificial turf pavement evaporates after watering, thereby suppressing the increase in surface temperature. it is conceivable that.
