[0008] The invention described in claim 3 is claim 1 or 2.
In the described floor or pavement pavement structure, the base surface was formed from concrete or mortar.

In the above invention, it is preferable to use stone as the aggregate and cement as the bonding agent.

[0010]

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 flowed to a predetermined thickness. , The base surface 2 is formed, and the base surface 2 is appropriately sloped so that water flows into the inlet 10 of the drain pipe 1.

The entrance 10 of the drain pipe 1 is covered with a wire net 11 or the like.

When forming the base surface 2 described above, concrete or mortar may be poured after reinforcing steel as a reinforcing material is incorporated on the floor.

Next, a first underlayer 3a is formed on the base surface 1.
And the second underlayer 3b are formed. The first underlayer 3a has an average particle diameter of 2 as an aggregate.
A gravel 5 having a weight of about 5 mm is used, and Portland cement 6 is used as a bonding agent. Thickness, i.e. in the embodiment shown in the figure, a 60 mm thick pouring and hardening,
The porosity with many continuous open pores 7 formed between them is about 25%
The first underlayer 3a having air permeability and water permeability is formed on the base surface 1.

The second underlayer 3b formed on the first underlayer 3a is composed of a gravel 5 having an average particle size of about 10 mm as an aggregate and a portland cement 6 as a bonding agent.
The mixture obtained by mixing and kneading water is poured into the first underlayer 3a with a predetermined thickness, that is, in the embodiment shown in the figure, a thickness of 100 mm and hardened to form continuous open pores 7 between the gravel 5. The second underlayer 3b having a large number of porosity of about 20% and having air permeability and water permeability is formed on the first underlayer 3a.

Further, a surface layer 4 is formed on the second underlayer 3b.
The surface layer 4 is formed by mixing a mixture of gravel 5 having an average particle size of about 5 mm as an aggregate, Portland cement 6 as a bonding agent and water, and kneading the second underlayer 3b.
Above, a predetermined thickness, that is, 20 mm in the embodiment shown in the figure.
The surface layer 4 having a large porosity of about 15% and having air permeability and water permeability with a large number of continuous open pores 7 formed between the gravel 5 is formed on the second underlayer 3b. .

Thus, on the floor surface paved as described above, since the grain size of the gravel 5 forming the surface layer 4 is as fine as 5 mm, there is no problem in walking, and water on the floor is not affected. Even if it flows, it immediately flows down to the base surface 2 through the continuous open pores 7, and is collected in the drain pipe 1 along the base surface 2.

Even dust and mud falling on the floor enter the continuous open pores 7, flow down to the base surface 2 together with the water flowing on the floor, and are collected by the drain pipe 1 along the base surface 2. It does not accumulate on the floor.

Therefore, it is not necessary to provide a gradient on the surface of the surface layer 4 on the floor surface described above.

Moreover, since the grain size 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 increased. Therefore, dust and dirt flowing into the continuous open pores 7 of the surface layer 4,
It is also suppressed that the continuous open pores 7 are clogged by mud on the way.

Further, even if there is noise, the noise is sucked into the continuous open holes 7, so that the noise can be reduced efficiently.

In the above embodiment, the first underlayer 3a
Was formed using a gravel 5 having an average particle size of 25 mm as an aggregate and having a large number of continuous open pores 7 between the gravel 5 and having a porosity of about 25% and air permeability and water permeability. The average particle size of the aggregate is not limited to this, but is in the range of 20 mm to 30 mm, and the porosity is 15%.
The range may be up to 35%.

In the above embodiment, the second underlayer 3b is formed by using the gravel 5 having an average particle size of 10 mm as an aggregate and forming a large number of continuous open pores 7 between the gravel 5 and having a porosity of about 2%. It was formed so as to have air permeability and water permeability of 20%, but it is not limited thereto. The average particle diameter of the aggregate is in the range of 6 mm to 20 mm, and the porosity is 15%.
It may be within the range of 30%.

In the above embodiment, the surface layer 4 is
Gravel 5 having an average particle size of 5 mm is used as an aggregate, and a large number of continuous open pores 7 are formed between the gravel 5 and the porosity is about 15%.
% Air permeability and water permeability, but is not limited thereto, and the average particle size of the aggregate is 3 m
m and less than 6 mm, and a porosity of 10% or more and 25% or less.

In the above embodiment, the underlayer 3 is formed by the first
Although the base layer 3a and the second base layer 3b are formed, the present invention is not limited to this. For example, as shown in FIG. Alternatively, the surface layer 4 may be provided on the underlayer 3.

That is, what is shown in FIG. 2 is a mixture obtained by mixing a gravel 5 having an average particle diameter of about 20 mm as the aggregate, a Portland cement 6 as a bonding agent and water, and kneading the mixture.
A base layer 3 having a porosity of about 20% and having air permeability and water permeability having a large number of continuous open pores 7 formed between the gravel 2 is poured on the base surface 2 and hardened by pouring a thickness of 100 mm on the base surface 2. After being formed, the average particle size is 5 mm as aggregate.
Gravel 5 and Portland cement 6 as bonding agent
The mixture kneaded with water and water is placed on the underlayer 3 for 30 m.
Then, the surface layer 4 having a porosity of about 15%, having a large number of continuous open pores 7 formed between the gravel 5 and having air permeability and water permeability, was formed on the underlayer 3 by being poured and hardening.

In the above embodiment, the base surface 2 is formed by flowing concrete or mortar on the floor to a predetermined thickness. However, the present invention is not limited to this.
A base surface hardened with sand or gravel may be formed, and an underlayer and a surface layer may be provided on the base surface.

FIG. 3 shows the road surface of the approach road formed by the pavement structure according to the present invention. The configurations of the base surface 2, the underlayer 3, and the surface layer 4 are the same as those of the embodiment shown in FIG. The difference is that the drain pipe 1 is poured into a U-shaped drain groove 8 arranged on one side of the road surface.

It is needless to say that the same effects as those of the above embodiment can be expected in the above embodiment.

In each of the above embodiments, as the aggregate,
Although the gravel is used, the invention is not limited to this. For example, crushed stone may be used, or crushed concrete lumps produced as industrial waste may be used.

In each of the above embodiments, Portland cement 6 is used as a bonding agent. However, the present invention is not limited to this. For example, an adhesive made of a synthetic resin material may be used as the bonding agent.
