[0007]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a garage floor formed by a pavement structure according to the present invention. First, a drain pipe 1 is laid on the floor, and concrete or mortar is poured to a predetermined thickness to form a base surface 2. Therefore, the base surface 2 is appropriately sloped so that water flows into the inlet 10 of the drain pipe 1.
[0008]
The inlet 10 of the drain pipe 1 is covered with a wire mesh 11 or the like.
[0009]
In addition, when forming the above base surface 2, you may pour concrete or mortar after incorporating the reinforcing bar as a reinforcing material on the floor.
[0010]
Next, the base layer 3 composed of the first base layer 3a and the second base layer 3b is formed on the base surface 1, and the first base layer 3a has an average particle diameter of about 25 mm as an aggregate. A gravel 5 having a large weight and Portland cement 6 as a bonding agent, and a mixture of the gravel 5 having the above particle diameter, the Portland cement 6 and water and kneaded, is provided on the base surface 1 with a predetermined thickness. That is, in the embodiment shown in the figure, the first foundation layer having a breathability and a water permeability of about 25%, in which a large number of continuous open pores 7 are formed between gravels 5 by being cast and cured to a thickness of 60 mm. 3 a is formed on the base surface 1.
[0011]
The second underlayer 3b formed on the first underlayer 3a is a mixture of kneaded gravel 5 having an average particle diameter of about 10 mm as an aggregate, Portland cement 6 as a bonding agent, and water. On the first base layer 3a, in the embodiment shown in the figure, it is poured and cured to a thickness of 100 mm to form a large number of continuous open pores 7 between the gravels 5 and the porosity is about 20%. The second foundation layer 3b having the air permeability and water permeability is formed on the first foundation layer 3a.
[0012]
Further, a surface layer 4 is formed on the second base layer 3b, and the surface layer 4 is formed by mixing gravel 5 having an average particle diameter of about 5 mm as an aggregate, Portland cement 6 as a bonding agent, and water. The kneaded material is poured into the second base layer 3b to a predetermined thickness, that is, in the embodiment shown in the figure, the thickness is poured to be 20 mm and cured to form a void ratio in which many continuous open pores 7 are formed between the gravels 5. The surface layer 4 having about 15% air permeability and water permeability is formed on the second underlayer 3b.
[0013]
Thus, since the particle size of the gravel 5 forming the surface layer 4 is as fine as 5 mm on the paved floor as described above, there is no problem in walking, and water is poured on the floor. However, it immediately flows down to the base surface 2 through the continuous open pores 7, and is collected in the drain pipe 1 through the base surface 2.
[0014]
Further, even if there is dirt or mud falling on the floor, it enters the continuous open pores 7 and flows down to the base surface 2 together with the water flowing on the floor, and is collected in the drain pipe 1 along the base surface 2 to be recovered. It does not accumulate on top.
[0015]
Therefore, in the above floor surface, it is not necessary to provide a gradient on the surface of the surface layer 4.
[0016]
Moreover, since the particle diameter of the gravel forming the base layer 3 is larger than the gravel forming the surface layer 4, the diameter of the continuous open pores 7 formed in the base layer 3 is inevitably large. It is also possible to prevent the continuous open pores 7 from being clogged with dirt and mud flowing into the continuous open pores 7.
[0017]
Further, even if there is noise, it is sucked into the continuous open pores 7, and the noise can be reduced efficiently.
[0018]
In the above embodiment, the first foundation layer 3a uses gravel 5 having an average particle diameter of 25 mm as an aggregate, and a large number of continuous open pores 7 are formed between the gravel 5 and a ventilation rate of about 25%. However, the present invention is not limited to this, and the average particle diameter of the aggregate is in the range of 20 mm to 30 mm, and the porosity is in the range of 15% to 35%. Good.
[0019]
Moreover, in the above embodiment, the second underlayer 3b uses gravel 5 having an average particle diameter of 10 mm as an aggregate and has a porosity of about 20% in which many continuous open pores 7 are formed between the gravels 5. Although formed so as to have air permeability and water permeability, the present invention is not limited to this, and the average particle diameter of the aggregate may be in the range of 6 mm to 20 mm, and the porosity may be in the range of 15% to 30%. That's fine.
[0020]
In the above embodiment, the surface layer 4 is made of gravel 5 having an average particle diameter of 5 mm as an aggregate, and a large number of continuous open pores 7 are formed between the gravel 5. Although formed so as to have water permeability, the average particle diameter of the aggregate is not less than 3 mm and less than 6 mm, and the porosity is not less than 10% and not more than 25%. I just need it.
[0021]
In the above embodiment, the base layer 3 is composed of the first base layer 3a and the second base layer 3b. However, the present invention is not limited to this. For example, as shown in FIG. Alternatively, a single underlayer 3 may be formed on 2 and a surface layer 4 may be provided on the underlayer 3.
[0022]
That is, what is shown in FIG. 2 is a mixture of kneaded gravel 5 having an average particle diameter of about 20 mm as an aggregate, Portland cement 6 as a bonding agent, and water, and a thickness of 100 mm on the base surface 2. The base layer 3 having a breathability and water permeability of about 20%, in which a large number of continuous open pores 7 are formed between the gravels 2 and hardened, is formed on the base surface 2 and then used as an aggregate. Gravel 5 having an average particle size of about 5 mm, Portland cement 6 as a bonding agent, and water mixed and kneaded are poured onto the base layer 3 to a thickness of 30 mm and cured, and continuous between the gravel 5 The surface layer 4 having air permeability and water permeability having a porosity of about 15% in which many open pores 7 were formed was formed on the underlayer 3.
[0023]
In the above embodiment, the base surface 2 is formed by flowing concrete or mortar to the floor at a predetermined thickness. However, the present invention is not limited to this. For example, a base surface solidified with sand or gravel is formed. And you may provide a base layer and a surface layer on this base surface.
[0024]
FIG. 3 shows the road surface of the approach road formed by the pavement structure according to the present invention, and the configuration of the base surface 2, the underlayer 3, and the surface layer 4 is the same as that of the embodiment shown in FIG. The difference is that the drain pipe 1 is poured into a U-shaped drain groove 8 disposed on one side of the road surface.
[0025]
Needless to say, the same effects as those of the above-described embodiment can be expected even in the above embodiment.
[0026]
In each of the above embodiments, gravel is used as the aggregate. However, the present invention is not limited to this, and for example, crushed stone may be used.
[0027]
