DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter pipe buried along a side edge of a permeable pavement constructed to allow rainwater falling on a road to pass therethrough, and more particularly, to guide gutter from the road side to the gutter pipe. The present invention relates to a gutter pipe which drains water in a drainage channel and simultaneously supplies water to a side opposite to a road to effectively drain rainwater on a road and a structure for disposing the gutter pipe.

[0002]

2. Description of the Related Art A permeable pavement road has been used for a long time as a pedestrian road, but its structure is to use a large amount of crushed stone aggregate having a large particle size and to form it while maintaining a high porosity. Since it is possible to maintain high pressure resistance by realizing a strengthened asphalt structure connecting the aggregates, construction as an automobile road is gradually increasing.

[0003] The structure of a permeable pavement road is transverse (in the width direction).
An impermeable lower roadbed having a thickness of about 80 mm is formed using a material made of asphalt-reclaimed crushed stone in a lower portion of about 270 mm of the sloped road ground, and each upper layer is made of a water-permeable asphalt mixture. It is formed by sequentially laminating a basic asphalt layer having a thickness of about 70 mm, an intermediate layer having a thickness of about 70 mm, and a surface layer having a thickness of about 50 mm.

On a permeable pavement road, when rain starts to fall, or when the amount of rainfall is small, the permeable structure allows rainwater to penetrate into the interior of the road using a large total area of the road and not to puddle on the road surface, so that walking is comfortable. be able to.

In particular, on an automobile road with a permeable pavement, since water splashing by a traveling vehicle does not occur, it is possible to travel smoothly without worrying about muddy splashing to pedestrians, This is effective in that the mud splashing does not temporarily cause a smoke phenomenon that obstructs the view of the following vehicle and safe driving can be obtained.

In addition, since a water film layer due to rain cannot be formed on the road surface due to the water permeability of the road, the occurrence of slip accidents due to the hydroplaning phenomenon during braking is reduced, and the safety of driving in the rain is ensured. But it is effective.

However, when a large amount of rainfall occurs in a short period of time, rainwater that has initially permeated by the water permeation function smoothly penetrates to the lower layer of the road and does not form a puddle or a water film layer on the road surface. If you continue to descend intensively to some extent, the permeability of the entire road will be saturated, resulting in the formation of puddles and water film layers on the road surface, especially near the side of the road due to the cross slope or in the low part due to the vertical slope. Become.

Therefore, the present applicant has drilled a guide hole to introduce permeated rainwater into the road-side wall surface of the road gutter.
We tried to drain this rainwater to the drainage channel in the gutter to discharge the rainwater that passed through the road.However, only the function of guiding the transmitted rainwater to the drainage channel using the holes alone was enough to satisfy the drainage efficiency of the road. Did not reach.

In the case of drainage of permeated rainwater through a drainage channel in a gutter through a guide hole or temporary heavy rainfall, the drainage channel itself becomes full, the drainage function becomes slow, and water permeability increases. The result was that the effect of absorbing rainwater into the gutter on the road was not as effective as expected.

[0010] Therefore, in the case of temporary concentrated rainfall,
A puddle or a water film layer still tends to be formed locally on the road surface, and there is a risk of causing an accident due to the smoking phenomenon and the hydroplaning phenomenon.

Further, in this type of conventional gutter and its road structure, a drain outlet is formed in which the upper side wall of the gutter is opened along the length direction, so that the gutter itself is poor in pressure resistance.
When transporting the gutter or installing it on the road, there were also problems such as easy damage due to impact and fluctuation.

Further, rainwater introduced and discharged into the gutter is treated at a sewage treatment plant to avoid flowing into a sea river, and is directly reduced to the earth to be retained and supplied to trees. Effectively reducing rainwater, such as torrential rain, to the ground, and focusing on gradually giving rainwater to plants and plants using the water retention of the soil, the drainage channel in the gutter is small and sufficient. Because it is possible, problems are raised in terms of the production cost and reinforcement of the gutter.

In addition, a problem arises in that the return passage of the gutter for returning rainwater to the ground is blocked by the grown root due to the invasion of the root accompanying the growth of the tree, thereby obstructing the supply of rainwater.

[0014]

SUMMARY OF THE INVENTION According to the present invention, in a gutter of a conventional permeable pavement as described above, rainwater permeated from the road surface is efficiently drained by the gutter to reduce a large amount of rainfall concentrated in a short time. Also eliminates the possibility of roads and gutters becoming saturated with permeated rainwater, eliminates the formation of water puddles and water film layers on road surfaces, ensures safe driving of vehicles, and makes the gutters rigidly constructed to withstand pressure And reduce rainwater operation by reducing rainwater to the ground.

[0015]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a grooved pipe having a main drainage channel along one of its longitudinal sides, and a water absorption hole communicating with the drainage channel is formed in one side wall of the grooved pipe. A water supply hole communicating with a drainage channel is provided in the side wall of the permeable pavement road, and a water absorption hole is formed along the side edge of the permeable pavement road on the road side. In addition, by disposing water supply holes toward the anti-road side and sequentially arranging them, rainwater permeated through the road is absorbed into the drainage channel through the water intake hole and at the ground on the anti-road side through the water supply hole. It is characterized by an arrangement structure of a gutter pipe for supplying water.

[0016]

The rainwater that has passed through the permeable pavement through the water intake hole of the gutter pipe is introduced into the drainage channel and discharged to prevent rainwater from accumulating on the road surface.

The rainwater introduced into the drainage channel is supplied separately from the drainage channel by using the wide capillary action of the ground made of ordinary earth and sand on the opposite side of the road through the water supply hole to assist drainage in the drainage channel, and quickly. Drains large amounts of rainwater.

In a gutter pipe having a water supply hole also formed in the bottom wall, the supply of rainwater to the ground works in multiple ways to supply a large amount of rainwater to the ground more quickly.

In the water supply hole in which the cutting blade is protruded, the root is naturally cut by the cutting blade due to the enlargement of the root of the tree that has entered the water supply hole, thereby preventing the root from further extending to the water supply hole. Improve the distribution of rainwater.

The drainage outlet with a trapezoidal cross section at the bottom spreads drainage when rainwater overflowing on the road surface is introduced into the drainage channel to prevent adhesion of mud and dust, thereby improving drainage.

In the drain outlet which is joined and closed in some places, the top wall has a rigid frame structure connected to the side walls and the bottom wall, thereby increasing the pressure resistance of the gutter tube.

The water guide groove formed on the outer surface of the water absorption hole collects and collects rainwater that has passed through the road, guides the rainwater widely up and down to the water inlet through the slope, and sucks it into the drainage channel.

In the water guiding groove having a lower bottom portion formed in a gutter shape having a U-shaped cross section, the collected rainwater is drained well from the gutter-shaped lower bottom portion, guided to the water absorption hole, and the water absorbing action to the drainage channel is activated. Work on.

A gutter pipe 1 has a top wall 2a of a gutter pipe body 2 having a main drainage channel 3 having a circular cross section along the length direction. A plurality of water-absorbing holes 6 are formed in one of the side walls 2b of the grooved pipe body 2 to open downward along the drainage channel 3 and communicate with the drainage channel 3 with a downward slope. The bottom wall 5a of the plurality of water guide grooves 5, 5 engraved at an angle up and down along the length direction communicates with the bottom wall 5a, and the drainage passage 3 is provided on the other side wall 2c.
A plurality of water supply holes 7, 7 leading to the hole are formed and formed of a concrete material.

As shown in FIG. 7, the water supply hole 7 is also formed in the bottom wall 2d of the grooved pipe 2, and the water supply hole 7 in the bottom wall 2d allows the rainwater in the drainage channel 3 to utilize the wide capillary action of the ground. In this way, the water can be returned to the earth from various angles, which is advantageous in that the drainage effect is improved.

In FIG. 7, reference numeral 7a denotes a cutting blade protruding into the water supply hole 7 in the direction of cutting the hole. The root of the tree which has entered the water supply hole 7 from the outside expands as it grows. Thus, the cutting blade 7a cuts off the roots that have invaded, improving the flow of the water supply hole 7, and is effective in preventing the supply and discharge of rainwater to the ground.

In some cases, the drainage port 4 is not provided at all, and individual drainage members are provided at the joints of the gutters 1 in the process of arranging on the road. Edges 10 and 10 made of a metal material are formed to form the opposing rims 4a and 4a to have a trapezoidal cross section that leads to the drainage channel 3 so as to spread to the skirt. Receiving steps 4b for receiving the drainage plate 9 made of metal are formed to face each other.

Further, as shown in FIGS. 3 and 7, the drain port 4 is formed by connecting a reinforcing bar 14 perpendicular to the reinforcing bar 14a along the length direction in a series, joining it in a closed shape 4c, and molding it with concrete. In addition, there is an advantage in that the pressure-resistant property and the impact resistance of the gutter 1 can be increased by partially eliminating the cross-sectional projecting structure by the drain port 4.

As shown in FIGS. 9 and 10, the joint 4c is a closed joint 4c of the drain port 4. A trapezoidal block plate 8 made of a thick steel plate for stress propagation is fitted into the drain port 4 over the entire length. Then, the drain plates 9 can be formed by joining the edge plates 10, 10 by welding 8a, and by reducing the interval between the joining portions 4c, 4c as shown in FIG.

It is formed by a plate 11 and its lower bottom 5a is communicated with each water absorption hole 6,6.

The water absorption hole 6 and the water supply hole 7 are formed by a water absorption pipe 12 and a water supply pipe 13 made of a non-corrosive material such as stainless steel or vinyl, as shown in FIGS.

The water guide groove 5, water absorption hole 6, and water supply hole 7 are
Instead of using the edge plate 11 and the pipes 12 and 13, it is also possible to perform concrete molding with a mold at the time of molding the grooved tube body 2 as shown in FIG.

The water absorption hole 6 and the water supply hole 7 can be effectively lowered and inclined in the direction along the flow of rainwater so that the functions of water absorption and water supply can be effectively performed. Due to the capillary action, sufficient water absorption and water supply can be obtained even by drilling horizontally.

Reference numeral 15 in FIGS. 1 and 2 denotes a curb joined to the top wall 2a of the grooved tube 2, which is provided by a construction structure.

Reference numeral 16 in FIGS. 1 to 3 denotes a packing made of an elastic material provided at the end of the groove tube 2, and the seam between the groove tubes 2, 2 connected along the length direction is formed in a watertight manner. I do.

As described above, the grooved pipe 2 is made of steel, stainless steel, vinyl or the like in order to achieve abrasion resistance and stainless steel at each of the drain port 4, the water guide groove 5, the water absorption hole 6, and the water supply hole 7. The rebars 14 and 14a are arranged using the above-mentioned materials, and a mold is formed from a concrete material.

An embodiment of the structure for arranging the gutter tube 1 according to the present invention will be described with reference to FIG. 11. A ground formed by laying coarse crushed stones and fine crushed stones in order and increasing the center of the road with a cross slope. About 80 m of asphalt material made of recycled asphalt is placed on the road ground 17a, which is about 270 mm below the surface.
m to form a water impervious lower subgrade 18
Above that, a basic asphalt layer 1 having a thickness of about 70 mm made of an asphalt mixture having a high water permeability and mainly composed of a coarse crushed aggregate having a large particle diameter and connected by an asphalt material.
9. Intermediate layer 20 having a thickness of about 70 mm, made of a permeable asphalt mixture mainly composed of crushed stone aggregate having a slightly smaller particle size, and a permeable stone mainly composed of crushed stone aggregate having a smaller particle diameter on its surface. A surface layer 21 of a thickness of about 50 mm made of a porous asphalt mixture is sequentially laminated and laid to form a permeable pavement 17.
To form

The gutter pipe 1 having a length of 1 to 1.5 m is embedded along the side edge 17b of the permeable pavement road 17 with the water absorption holes 6 being arranged toward the road 17 side and being connected sequentially. Filters 22 and 22 are attached to the outer side 1a of the water absorption hole 6 and the water supply hole 7, respectively.

Although not shown, it is possible to prevent earth and sand from flowing into the gutter 1 by adding coarse crushed stone having a large particle size in place of the filter 22.

A sidewalk 23 in which a tree 24 is planted is disposed on a sidewalk ground 23a on the side opposite to the side of the gutter tube 1, and a side edge 2 of the sidewalk 23 is provided.
A curb 25 is arranged on 3b to form a road.

The above-described structure for arranging the gutter pipe for a permeable pavement has been described for the embodiment provided adjacent to the sidewalk 22 on which the street tree 24 is provided. It can be constructed as a countryside or a mountain.

In the gutter tube 1 according to the present invention, the water suction hole 6 communicates with the drain passage 3 at an upper position, and the water supply hole 7 communicates with the water passage at a lower position, so that the suction operation can be performed smoothly. Due to the drainage suction power of the rainwater in the drainage channel 3 and the large capillary action by the ground on the side opposite to the road, the positional relationship does not necessarily have an effect when a large amount of rainwater is discharged.

[0045]

According to the present invention, a large amount of rainwater, which has been temporarily concentrated and falls, is introduced into the gutter pipe and smoothly and quickly discharged from the above-described structure of the gutter pipe of the permeable pavement. Effectively utilizes the characteristics of permeable roads, improves the durability of gutters, and reduces and reduces sewage treatment operations by reducing rainwater supply to the earth without draining as much of the seawater as possible. There is.

In other words, the present invention is characterized by a gutter pipe having a water absorption hole formed on one side wall and a water supply hole formed on the other side wall in communication with the drainage passage of the gutter pipe body. The water intake hole is directed toward the road side along the side edge, and the water supply hole is directed toward the opposite road side and is buried.

Thus, the rainwater permeated into the interior by the permeation function of the road is sequentially collected at the side edge by utilizing the cross slope of the road, introduced into the drainage channel of the gutter through the water intake hole, and discharged to the road surface. Although it is intended to prevent accumulation and formation of a water film layer, in the gutter pipe for a permeable pavement of the present invention, rainwater temporarily concentrated and concentrated, that is, a short time such as concentrated torrential rain. When the drainage channel of the gutter pipe is saturated with a large amount of rainwater and the drainage capacity is exceeded, the water is sucked and discharged from the drainage channel through the water supply hole due to the capillary action of the large natural ground made of debris and the water absorption of vegetation. Return to the ground as much as possible in a separate route from the drainage channel, and reduce sewage treatment operation.

As described above, drainage of permeated rainwater in the drainage channel is assisted to prevent water accumulation on the surface of the permeable pavement road even in the case of temporary torrential rain and to reduce the diameter of the drainage channel. Therefore, a robust gutter tube with high pressure resistance can be configured.

Therefore, it is possible to prevent the running and hydroplaning phenomena of the running vehicle from occurring during the operation of the vehicle under heavy rainfall, thereby ensuring safe driving and running in the rain. At the same time, the pedestrian does not have to worry about splashing muddy water, has a smooth running flow, and has an effect that the vehicle can be easily driven in the rain.
