Abstract

PROBLEM TO BE SOLVED: To provide a permeable pavement road excellent in permeability and workability at a low cost, by burying a drain induction material provided with a three-dimensional netted structure in which voids are formed by entangling a synthetic resin linear material, under the permeable paved part and connecting it to a side drain. SOLUTION: A plurality of synthetic resin linear material 2 are folded to be mutually entangled and sticking the contact points to each other to form voids and also a bar-form drain-induction body 1 having a three-dimensional netted structure excellent in a pressure-resistant property. The drain-induction body is both longitudinally and latitudinally laid on a relatively impervious paving binder course 4 and a water-pervious asphalt paving 5 is laid thereon. Required positions of both lateral ends of the drain-induction body 1 are connected to the side drain 6, a drain pit, a drain passage, etc. The drain-induction body 1 made of a synthetic resin reduces the cost and the weight and increases the workability. And the three-dimensional netted structure increases the voids and the draining efficiency and also the pressure-resistant property.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for draining seepage water and a drainage derivative on a water-permeable paved road. In addition,
Roads include roads, sidewalks, and bridges.

[0002]

2. Description of the Related Art For example, if rainwater or the like stays on the road surface of a road, the car may cause an accident due to a hydroplaning phenomenon, and the water splash caused by the car may cause trouble to pedestrians. Therefore, in order to solve such problems, roads are often provided with water-permeable pavement.

Water permeates the inside of such a water-permeable paved road, but it is necessary to guide the permeated water to a drainage basin or a gutter to drain it. Conventionally, as such a drainage derivative, there is a metal wire rod bent into a spiral shape into a pipe shape.

[0004]

The conventional metal spiral pipe as described above is expensive, has poor durability and workability because it is easy to rust and is heavy, and has poor drainage performance because it has a small side opening ratio. There was such a problem. An object of the present invention is to provide a novel drainage method and drainage derivative that can solve such problems.

[0005]

SUMMARY OF THE INVENTION The above object is achieved by the method of the present invention, that is, a plurality of synthetic resin linear bodies 2 are creased and entangled, and contacts are attached to each other while forming a gap therebetween. It is possible to embed the rod-shaped drainage derivative 1 having a three-dimensional network structure excellent in pressure resistance, which is assembled and formed as described above, under the water-permeable pavement portion 5 of the road 3 and connect it to the drainage channel such as the drainage basin or the gutter 6. It can be achieved by a characteristic drainage method.

The above-mentioned method of the present invention uses the drainage derivative of the present invention, that is, a plurality of linear bodies 2 made of synthetic resin.
Are entangled and entwined, and the contacts are attached to each other to form a gap between them to form a three-dimensional network structure having excellent pressure resistance and formed into a rod shape, and the water permeability of the road 3 is formed. It can be carried out by the drainage guide 1 characterized in that it is buried under the flexible pavement portion 5 and is connected to a drainage channel such as a drainage basin or a gutter 6.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. First, FIG. 1 shows a drainage derivative 1. This drainage derivative 1 is a three-dimensional net-like structure excellent in pressure resistance as a plurality of linear bodies 2 made of synthetic resin are wrinkled and intertwined with each other, and the contact points are attached to each other to form a void between them. It has a structure and the overall shape is a round bar. The drainage derivative 1 may be rod-shaped and long, and its cross-sectional shape is arbitrary and may be circular or square as described above. Alternatively, it may be hollow to form a cylindrical rod.

The drainage derivative 1 is manufactured as follows. That is, a thermoplastic synthetic resin such as polypropylene is heated and melted by an extruder provided with a plurality of downward nozzles, and then continuously extruded downward by the above nozzles to form a plurality of linear bodies 2 and descend. Then, the linear members 2 are wrinkled and entangled with each other by taking up the linear members 2 at a speed lower than the descending speed before the linear members 2 are still solidified at the lower position thereof, and their contact points are used for their adhesiveness. Then, they are assembled by sticking to each other to form a three-dimensional network structure, which is then cooled by a method such as immersing in cold water to solidify, then pulled up and cut into an appropriate size.

Next, FIGS. 2 and 3 show a road (road) 3 on which the drainage method of the present invention is carried out. This road 3 has the above-mentioned drainage guides 1 installed vertically along the road shoulders on both sides of the pavement base layer 4 where the water permeability is not good, and the above drainage is also provided in the lateral direction across the road at required intervals. The derivative 1 is installed, and a permeable asphalt pavement is applied on the derivative 1 so as to fill the drainage derivative 1. Reference numeral 5 indicates the water-permeable pavement portion 5. In addition, both ends of the horizontal drainage guide 1 are connected to the vertical drainage guide 1,
The drainage guide 1 in the vertical direction is connected to the side groove 6 at a required position.

Therefore, the rainwater that permeates and permeates the water-permeable pavement portion 5 of the road 3 is guided by the drainage guide 1 to the gutter 6
Are collected and drained. The drainage guide 1 may be connected to a drainage basin or other drainage channel instead of the gutter 6.

[0011]

EFFECTS OF THE INVENTION The drainage method and drainage derivative of the present invention are as described above. Construction of the drainage derivative 1 is made of synthetic resin so that the cost can be reduced, and the weight is reduced and the bending is easy. There is an advantage that the property is improved. Further, since the drainage derivative 1 has a three-dimensional network structure, the aperture ratio of the side surface and the overall porosity are large, and the drainage performance is high.
Incidentally, in the case of the above-mentioned conventional spiral pipe, the opening ratio of the side surface is about 50%, but the drainage derivative 1 of the three-dimensional net structure of the present invention can raise the opening ratio to about 80%. Further, since the drainage derivative 1 has a three-dimensional network structure and is made of synthetic resin, it has excellent pressure resistance and is not crushed by the pressure of the water-permeable pavement, and the drainage function can be reliably maintained. . In addition, the drainage derivative 1 has a low internal thermal conductivity due to its three-dimensional network structure, and even when it comes into contact with high-temperature asphalt, the linear body on the surface is softened and slightly deformed, and the internal structure hardly changes. There is no effect on sex.
Further, since the wastewater derivative 1 of the present invention is made of synthetic resin, it is excellent in durability without fear of rusting unlike metal ones.
