[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to a water-permeable substrate in order to prevent the water-permeable substrate from being clogged by the embankment when it is planted on the roof of a building or for other artificial garden construction. The present invention relates to a method of laying a non-woven fabric.

[0002]

2. Description of the Related Art Conventionally, a large number of water-permeable substrates are laid directly on a concrete pouring surface such as a rooftop of a building or on the surface of which waterproofing is applied on the upper surface, and an embankment or the like is applied on the surface to construct an artificial structure. It was a garden. When the embankment is placed on the above-mentioned water-permeable substrate, the embankment may enter the water-permeable holes formed in the water-permeable substrate and the water-permeable base holes may be clogged. The entire substrate was covered with a non-woven fabric.

[0003]

SUMMARY OF THE INVENTION According to the present invention, when the entire upper surface of the above-mentioned water-permeable substrate arranged in large numbers is covered with a non-woven fabric and it takes a certain amount of time to apply embankment thereon, Since the water permeable substrates are laid out side by side on the roof of a building, etc., the wind may blow the non-woven fabric, and the non-woven fabric may be displaced when embankment, and the non-woven fabric covered on the water permeable substrate. Need to be locked on the water-permeable substrate. Therefore, it is an object of the present invention to provide a method for locking a nonwoven fabric on a water-permeable substrate when covering the nonwoven fabric on a large number of water-permeable substrates.

[0004]

In order to achieve the above-mentioned object, a method of laying a non-woven fabric for preventing clogging of a water-permeable substrate according to the present invention is a water-permeable substrate made of a foamed resin having closed cells and having a predetermined thickness. Laying a large number on the rooftop, etc., when covering the entire surface of the large number of water permeable substrates with a non-woven fabric for preventing clogging of the large number of water permeable substrates arranged, a width wider than the width of the water permeable substrate, and A feature that the non-woven fabric wound in a roll shape is rolled and laid on the water-permeable substrate arranged in a large number and the non-woven fabric is locked to the water-permeable substrate after or at the time of laying. It is what

[0005]

[Operation] A non-woven fabric wound in a roll shape is rolled and transferred to the surface of a water-permeable substrate laid on a concrete placing surface such as a rooftop, and the non-woven fabric is locked. Use a tool or an adhesive tape to lock the water-permeable substrate, or double-sided adhesive or one side of the adhesive tape on the surface of a large number of water-permeable substrates and roll it into a non-woven fabric. By transferring while rolling, by sticking to the other surface of the double-sided adhesive or adhesive tape, the non-woven fabric is stuck to the surface of the water-permeable substrate, and the width of the non-woven fabric is that of the water-permeable substrate. Since the width is wider than the width, the contact side surface of each of the water-permeable substrates arranged in a large number is necessarily covered with the non-woven fabric, and the embankment does not flow out from the contact portion.

When covering the non-woven fabric 10 wound in a roll shape wider than the width of the non-woven fabric, first, the non-woven fabric 10 wound in the roll form is placed on the edge of the water-permeable substrate 1, 1, 1 ,. One end of the double-sided adhesive tape or the double-sided adhesive tape 14 is fixed to the surface of the water-permeable substrate 1, 1, 1, ... Stick the surface. This double-sided adhesive tape 14 is attached
Can be attached to a plurality of water-permeable plates 1, 1, 1, ... Next, by exposing the adhesive portion on the other surface of the double-sided adhesive tape 14 and rolling the non-woven fabric 10 rolled to move to the other edge, the double-sided adhesive tape is formed. Tape 14, 14,
The non-woven fabric 10 is locked on the water-permeable substrates 1, 1, 1, ... by this, and the whole non-woven fabric 10 can be covered with the non-woven fabric 10 by repeating this operation in sequence. Is.

As described above, in the above embodiment, when the nonwoven fabric 10 is covered on the entire surface of the water-permeable substrates 1, 1, 1, ... Since the nonwoven fabric 10 having a width wider than that of the water permeable plate 1 is laid on the surface of the water permeable substrate 1 while rolling, and the nonwoven fabric is locked to the water permeable substrate 1 after or during the laying, a large number of water permeable substrates are provided. 1, 1, 1, ... The non-woven fabric 1 laid so as to cover the whole has no fear of being blown by wind or the like, and moreover, the water-permeable substrate 1 used in this embodiment.
Has a width of 90 cm, and the non-woven fabric 10 is a roll having a width of 1 m and a length of 100 m.
Each water-permeable substrate 1, ...
The contact part on the side of ... is surely covered with the non-woven fabric, and since the roll-shaped non-woven fabric is rolled during the above-mentioned laying, its workability is extremely good.
The mode of locking is also simple.

In the present embodiment, the non-woven fabric laid on a large number of water-permeable substrates 1, 1, 1, ... Is surely covered up to the embankment 15 without being affected by wind or the like. Since the non-woven fabric does not shift when embankment is performed, even if the embankment 15 is constructed in this state, the sand and sand of the embankment 15 will be clogged in the water permeable holes of the water permeable substrate, and the water cannot be permeable. In addition, the water-permeable substrate 1 used in this example also has a water-retaining property, and is suitable for planting an artificial garden provided in a lobby or a rooftop. And, in the above-mentioned examples, the wound non-woven fabric was explained by immediately laying it. However, in the case of a narrow area or a slightly complicated construction, the non-woven fabric cut according to those shapes is used. Needless to say, it is installed and locked.

[0015]

According to the method of laying a nonwoven fabric for preventing clogging of a water-permeable substrate according to the present invention, a large number of water-permeable substrates made of foamed resin with closed cells having a predetermined thickness are laid on a rooftop or the like, and the plurality of the water-permeable substrates are laid out. A nonwoven fabric composed of synthetic fibers or the like that is wider than the width of the water-permeable substrate and wound in a roll is laid while rolling the surface of the water-permeable substrate that is laid out in large numbers, and during or after this laying. Since the non-woven fabric is locked to the water permeable substrate, the laid non-woven fabric is not blown off by wind or the like, covers the entire surface of many water permeable substrates, and the width of the non-woven fabric is wider than the width of the water permeable substrate. Since it is formed in a wide width, the contact portion on the side surface of each laid water permeable substrate is surely covered with the non-woven fabric, so that even if embankment is applied, the earth and sand will not flow out from the contact portion. , At the time of embankment Since the cloth does not shift and the entire water-permeable substrate is covered with the non-woven fabric as described above, the water-permeable holes will not be clogged even when embankment is made, and the locking can be done easily. Since it also rolls a roll-shaped nonwoven fabric, its workability is good.
