The present invention facilitates drainage of rainwater on roads paved with small permeable asphalt or asphalt concrete, and prevents water from being stored due to the formation of curved surfaces on the road surface due to partial subsidence or topography of the ground. It relates to the rainwater drainage structure of the pavement.

Asphalt or asphalt concrete, which is widely used as a paving material for roads, is added to mixed soil such as fine and fine cement and sand in order to minimize cracks on the road surface and maintain a certain flatness. Therefore, roads coated with such asphalt or asphalt concrete have low water permeability and are difficult to expect drainage from the road surface.

1 is a view schematically showing a cross-sectional structure of a pavement, it will be described with reference to this.

As shown, the pavement road is to form a asphalt layer 40 by applying the pavement material on the soil layer 50, the support layer, there is no drainage function on the road surface itself, the drainage line 30 along the edge of the road Install. In addition, the surface of the pavement is formed to be convex, so that water generated on the surface of the road due to rain or the like can flow toward the drainage line 30.

However, the curved surface 41 may be formed on the surface of the pavement due to the settlement of the soil layer 50 and the pressure applied to the pavement.

The curved surface 41 is a road that loses its flatness and sinks to a certain depth. When water is supplied to the surface of the road due to rain or the like, the curved surface 41 does not flow to the drain line 30 and the curved surface 41 does not flow. Is stored.

The water (W) stored in this way may damage the pedestrians passing by the pressure of the traffic vehicle, passing through the sidewalk 10, and may obstruct the driver of the nearby driving vehicle or be surprised by a sudden shock. Could give.

Unexplained withdrawal symbol '31' covers the open upper surface of the drain line 30 as a cover.

Unexplained withdrawal symbol '32' is a drain, allowing the inflow of water through the cover (31).

Unexplained withdrawal symbol '20' is a driveway.

Therefore, the present invention was devised to solve the above problems, and prevents water from accumulating to a point formed due to a curved surface formed by a portion of the pavement or a geographic feature, and prevents water from accumulating, and supports the road to a soil layer. It is a technical task to provide a rainwater drainage structure on a pavement that can supply groundwater to prevent the destruction of underground ecosystems.

The present invention to achieve the above technical problem,

A hollow pipe is formed, the upper end is adjacent to the surface of the pavement road and the bottom is vertically buried so as to be located on the soil layer via the asphalt layer, the circumferential surface is formed with a plurality of drainage holes for opening the hollow;

A flat plate having a plurality of through holes for increasing binding force as the pavement material of the road flows, the fixing plate having a plurality of drain pipes fixed at predetermined intervals and embedded in an asphalt layer;

A buffer plate made of a synthetic resin material which covers the top and bottom surfaces of the fixing plate so that the packaging material does not directly contact the surface of the fixing plate and has through holes corresponding to the through holes;

A buffer tube covering an outer circumferential surface of the drain pipe positioned in the asphalt layer so that the pavement material does not directly contact the surface of the drain pipe, and covers the upper top surface of the drain pipe so that the top of the drain pipe does not directly appear on the surface of the pavement road; And

A concave drain groove is formed on a flat plate, and at the lower end of the drain groove, a water flow distribution plate having a hole so that water introduced into the drain groove penetrates downward;

Rainwater drainage structure of the pavement consisting of.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 is an exploded perspective view illustrating a connection relationship between the components constituting the rainwater drainage structure according to the present invention, Figure 3 is a cross-sectional view showing a rainwater drainage structure according to the present invention, it will be described with reference to this.

Rainwater drainage structure according to the present invention is the drainage pipe 131 and the drainage pipe 131 is fixed to the soil layer 50 through the asphalt layer 40 and the fixing plate 133 for fixing the drain pipe 131, and the drain pipe Water flow distribution pipe 150 for dispersing the rainwater drained through the 131 as wide as possible to be evenly immersed in the soil layer (50).

The drain pipe 131 has a hollow tube shape, and has a plurality of drain holes 132 on a circumferential surface thereof and is embedded to penetrate the asphalt layer 40 and the soil layer 50. At this time, the drain hole 132 is formed only at one point of the drain pipe 131 at the position of the soil layer (50). This is because rainwater drained into the drain pipe 131 penetrates the asphalt layer 40, thereby weakening the durability of the pavement, and further, by shortening the adhesion and mucus of the asphalt quickly, thereby shortening the life of the pavement. .

On the other hand, the drain pipe 131 according to the present invention was molded to the bottom point so that it can be easily driven into the soil layer (50).

As described above, the drain pipe 131 is embedded so as to pass through the asphalt layer 40 and the soil layer 50, the upper end is located near the surface of the asphalt layer 40, the lower end is located in the soil layer 50 do. Of course, since the drainage of the water stored in the curved surface 41 is made through the drain pipe 131, the hollow of the drain pipe 131 is opened through the upper top surface of the drain pipe 131, and the open top surface is thus a curved surface ( Should be exposed on the surface.

Since the pavement is built for the purpose of vehicle traffic, when a vehicle having a weight of several tons passes, a large vibration occurs on the surface of the road, which is transmitted to the drain pipe 131. Therefore, the drain pipe 131 embedded in the asphalt layer 40 may be out of position, and if so, there is a risk of breaking the pavement.

In the rainwater drainage structure according to the present invention, the fixing plate 133 is further provided to reduce shaking of the drain pipe 131. The fixing plate 133 is embedded in the asphalt layer 40 in a state where the drain pipe 131 is fitted, and a plurality of through holes 134 are formed in the fixing plate 133 to strengthen the binding with the asphalt.

Therefore, the fixing plate 133 is buried in the asphalt layer 40 while fixing a plurality of drain pipes 131 collectively, the drain pipe 131 is out of position or shaken due to the vibration force or various external forces generated Can be minimized.

Subsequently, the drainage structure 130 consisting of the drain pipe 131 and the fixing plate 134 constituting the rainwater drainage structure according to the present invention should have a rigidity that can maintain its shape to resist the weight of asphalt, It is made of metal or hard synthetic resin. However, when the drainage structure 130 is hardened, the contact surface may be damaged by the collision with the asphalt layer 40. Therefore, a part of the drainage structure 130 that is in direct contact with the asphalt layer 40, that is, the entire fixing plate 133 and the upper end of the drainage pipe 131 should have a buffer property, and for this, rainwater according to the present invention. The drainage structure further includes buffer plates 110 and 120 covering the upper and lower surfaces of the fixing plate 133, and a buffer tube 140 covering the upper surface of the drain pipe 131.

Since the buffer plates 110 and 120 and the buffer tube 140 should have a predetermined elasticity, the buffer plates 110 and 120 and the buffer tube 140 may have a rubber material having a predetermined thickness. On the other hand, in the case of the buffer plate (110, 120) has a through hole (111, 112) for the reaction with the through hole (134). The through holes 111 and 112 should be formed at positions corresponding to the positions of the through holes 134. The through holes 111 and 112 may be formed by covering the buffer plates 110 and 120 and drilling the corresponding positions while manufacturing the fixing plate 133. There will be.

On the other hand, the buffer tube 140 is to cover not only the top outer peripheral surface of the drain pipe 131 but also the top end. That is, the buffer tube 140 is to be in contact with the asphalt layer 40 as much as possible. As described above, since the drain pipe 131 is a hard material having a predetermined rigidity, when the upper end of the drain pipe 131 protrudes to the surface of the asphalt layer 40, the tire of the vehicle may be damaged. . Therefore, the buffer tube 140 is to cover the top end of the drain pipe 131 as shown in Figure 3 it is preferable to reduce the possibility of damage to the tire.

Meanwhile, the rainwater drainage structure according to the present invention drains rainwater through the drain pipe 131 partially buried, so that the drained water is concentrated only at a limited position of the soil layer 50. However, when the drain pipe 131 is densely formed, the binding force of the asphalt layer 40 is weakened, so the number of the drain pipes 131 to be buried is limited.

Therefore, even when draining through a small amount of drain pipe 131, the oil and water distribution plate 150 is further included to make the water drained to the soil layer 50 as uniform as possible.

The oil and water distribution plate 150 is in the form of a plate having a plurality of drain grooves 151, the drain groove 151 is inclined so that water formed on the oil and water distribution plate 150 flows in, the water flowing in the bottom Holes 152 are formed to penetrate into the soil layer 50.

Therefore, even if the distance between the neighboring drain pipe 131 is far away and only water is concentrated in a specific position, the water is dispersed in the water distribution plate 150 buried under the drain pipe 131 relatively wide and as wide a range as possible Allow water to flow in.

On the other hand, even if the oil distribution plate 150 is slightly inclined, the water flowing into the upper surface of the oil distribution plate 150 does not flow down the upper surface of the oil distribution plate 150, the inclined drain groove 151 formed Can be discharged through.

In the illustrated figure, the diameter of the drain groove 151 is relatively larger than the size of the drain pipe 131 and the separation distance between the drain pipe 131 is also shortened, but this is the appearance of the rainwater drainage structure according to the present invention It is conceptually illustrated to be shown, and in reality, the drain groove 151 is small in diameter and adjacent to another neighboring drain groove 151, and the drain pipe 131 may also be disposed relatively far from other neighboring drain pipes.

According to the present invention as described above, while the bent portion formed at one point of the pavement road or the geographic feature is installed at the point where the water is concentrated on the pavement, the drainage of the deceased water is directly drained from the pavement, while the drainage is a pavement road Since it becomes the soil layer 50 which supports the water, it can supply water to the soil layer below the road where the ratio of groundwater falls relatively.
