Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mold material capable of easily and reliably forming a pavement having good water permeability such as rainwater, and a method of forming a water-permeable pavement using the mold material. Regarding the offer.

[0002]

2. Description of the Related Art Conventionally, sidewalks, roads, various plazas, playgrounds,
As a pavement means for various spaces such as a facility installation site in a park, a parking lot, and a garage interior space, a pavement having water permeability may be required instead of various non-permeable pavements such as concrete pavement.

[0003] Such pavements having water permeability are usually prepared by forming concrete blocks along the pavement edge of the ground to be paved and forming the pavement edge in advance, or by forming the pavement edge in advance along the pavement edge. An edge is formed and prepared, a pavement material is sequentially laid inside the pavement edge portion, and a resin binder is sprayed on the pavement material. I was trying to do it.

[0004]

However, in such a method for forming a pavement, prior to the formation of the pavement, a pavement edge used for laying the pavement material is prepared by juxtaposing concrete blocks. Alternatively, it is necessary to form a temporary formwork along the edge of the ground to be paved, and to put concrete in the temporary formwork and cure the concrete form to form a pavement edge in advance so that water permeability is required. Prior to the formation of the pavement of nature, it is necessary to perform pretreatment with a lot of equipment and materials and a lot of construction work, which is difficult in terms of cost and construction period.

[0005] From this point, as shown in FIGS. 15 to 17, a perforated plate 130 is set on the pavement ground 100, and a pavement material 111 such as crushed stone is laid inside the perforated plate 130. Then, a resin binder is sprayed and cured so that the pavement materials 111 such as crushed stones are integrally bonded to each other, and in view of curing of the resin binder, the perforated plate 130 is removed.
It has been studied to form a water-permeable pavement body 110 having a water-permeable decorative surface layer by applying a surface decorative material 112 to the surface to be removed and the surface on which the paving material 111 is laid.

However, in the method of forming the pavement body 110, the pavement members 111 laid inside the through plate 130 are sufficiently bonded and fixed by the curing of the resin binder spread on the pavement member 111. It was considered that a curing period was required to complete the process, and a considerable period of work was required until the penetration board 130 was removed and the surface makeup was applied.

A pavement 110 shown in FIGS. 18 and 19 is formed by the same method as that shown in FIGS. 15 to 17, and a pavement thickness H in the pavement 110 thus formed.
However, for example, when the pavement 110 is formed so as to be 10 cm or more, the resin binder sprayed on the pavement material 111 does not sufficiently reach below the pavement material 111 laid on the inner side of the through plate 130. When the penetration board 130 was removed, a problem that the pavement 110 collapsed from below the removal surface was expected.

The present invention solves the problem in forming such a conventional water-permeable pavement, and can easily provide a pavement having water permeability effectively with a short construction period. It is an object of the present invention to provide a mold material and a simple method of forming a water-permeable pavement.

On the other hand, there is provided a method for forming a water-permeable pavement characterized by laying a pavement material.

In the form material and the paving method configured as described above, the form material is set along the edge of the ground to be paved, and the paving material is laid inside the form material. By doing so, a water-permeable pavement having a substantially vertical pavement side surface of an arbitrary height can be easily and reliably formed.

Further, as the reactive resin, for example, a reactive resin obtained by mixing 50 to 90% by weight of a bisphenol A type epoxy resin and 10 to 50% by weight of a water-soluble polyamine resin can be used. .

The lower pavement layer 11 is constituted by the lower pavement layer 11 and the upper pavement layer 12 each having a required thickness on the pavement ground B partitioned by the formwork material 30 '. Between each crushed stone in the crushed stone aggregate Wa,
The pavement main body 10 is configured so as to have a gap through which rainwater passes between crushed stones in the crushed stone aggregate Wb constituting the upper pavement layer 12.

Following the formation of the pavement main body 10,
Without waiting for the curing of the reactive resin used in the configuration of the pavement main body 10, or at any time after the formation of the pavement main body 10, the surface of the second plate part 32 of the formwork material 30 ' The water permeable surface layer 20 is formed on the pavement main body 10 made of the pavement material W laid with the damping plate surface and the upper end surface and side surfaces of the second plate portion 32.

Here, the pebble aggregate Wc constituting the water-permeable surface layer 20 is, for example, a pebble having a particle diameter of 7 mm or a pebble under a sieve sieved using a sieve through which a pebble having a smaller particle diameter passes. In addition, a pebble having a particle size of 3 mm or a larger particle size is prepared as an aggregate of pebbles having a particle size remaining on the sieve when sieved with the sieve remaining on the sieve.

Such pebbles may be rocks that have been finely divided in any way, such as those in which rocks have been refined by natural phenomena and those in which rocks have been artificially crushed. Also, it may be of any form, and may be of any stone type. For example, various crushed stones obtained by artificially crushing various rocks such as plutonic rocks, semi-plutonic rocks, and volcanic rocks, and various types of gravel such as naturally occurring river gravel, sea gravel, and mountain gravel are used.

The above-mentioned pebbles refer to a single piece of gravel obtained by reducing such a rock by natural action and a single piece of crushed stone obtained by artificially crushing a rock by a crusher or the like. , And the aggregate in which the gravel and the crushed stone are mixed is referred to as a pebble aggregate Wc.
