The present invention relates to a trickle filter opening for a road drainage system, and more particularly, to a trickle filter opening for a road drainage system to prevent the introduction of various kinds of contaminants into the rain gutter, and to effectively introduce rainwater.

In general, the road is provided with a drainage system for draining rainwater, the drainage system comprises a rain gutter 5 and a sewer pipe (not shown) connected to the bottom of the road as shown in FIG.

Rain gutter (5) serves as an inlet through which rainwater flowing down the roadside flows, the open upper surface of the rain gutter (5) prevents vehicles or passers-by falling into the rain gutter (5), at the same time A grating 7 is installed to prevent the rain gutter 5 from flowing into it.

The grating (7) is made of a steel material lattice form, because it has a relatively large mesh (目) can be filtered to some extent in the case of large coarse (보다 大) large enough than the mesh, but the volume such as soil, tobacco butts and leaves Will not be able to filter for small contaminants.

Therefore, as the time passes, various contaminants accumulate in the rain gutter 5, and in some cases, the sewage pipes connected to the rain gutter 5 are blocked so that the drainage of the rain water is not smoothly made. .

If there is a heavy rainfall, such as during the rainy season, there is a concern that the sewage pipes may be blocked by rainwater flowing back from the rain gutter 5 disposed in the lowlands, and the roads may be flooded.

 Therefore, according to the prior art, a cleaning operation for removing the accumulated contaminants in the rain gutter 5 is required before the problems as described above are exacerbated. As the worker enters the rain gutter (5) and pulls out the contaminants, it requires as much labor and manpower.

In order to solve such a problem of the prior art, a method of using a so-called fine-grained grating (not shown) with fine mesh or installing a basket-type strainer (not shown) under the grating has been devised.

However, according to the method using the fine grating, although a large amount of contaminants do not flow into the rain gutter 5, the fallen leaves or plastic paper swept away from the rain accumulate on the grating 7, thereby blocking the net surface. There is a problem in that rainwater is easily accumulated, and according to the method of using a strainer, there is a problem that a still hard work of lifting grating is required to remove the debris accumulated in the strainer.

The present invention has been made to solve the above-mentioned conventional problems, and is installed on the grating to prevent the entry of contaminants into the rain gutters, and at the same time, the purpose of the provision of the contaminant filter opening for the road drainage system to allow the rain water to flow smoothly.

The vertical blocking network 26 is a panel-shaped grid structure, which is placed inside the internal net 24 to cross the inner space of the internal net 24 in the longitudinal direction. Reference)

The support network 28 is also formed in the form of an extension from the edge of the cover network 20 is also a lattice structure and extends to the outer end of the outer tunnel network 22 by the inner network 24 and the vertical intercept network 26 It is in the form of supporting (see Figure 4).

The cover net 20, the outer tunnel network 22, and each surface of the inner tunnel network 24 is provided with a plurality of spaced apart pins 21, 23, 25 protruding upward by a certain height.

The spacing pins 21, 23, 25 are preferably configured such that their heights are different from each other.

Here, as shown in FIG. 4, the outer tunnel network 22 and the inner tunnel network 24 are formed on the outer side (cover) based on a virtual vertical line formed by the vertical blocking network 26 (shown in the drawing). When divided into the opposite side of the network) and the inner side (part close to the cover net), the inner side of the inner side of the tunnel net 24 (241) is formed denser than the outer portion 221 of the outer tunnel net 22, The vertical blocking net 26 is formed denser than the outer portion 241 of the inner mesh 24, the inner portion 242 of the inner mesh 24 is denser than the vertical blocking network 26 Is formed, the inner portion 222 of the outer tunnel network 22 is formed denser than the inner portion 242 of the inner tunnel network 24 from within.

To describe the mesh size of each net in detail, the outer mesh 221 of the cover net 20 and the outer tunnel net 22 is preferably made of a size having a width of about 15 mm, and the inner net 24 of the net The mesh of the outer portion 241 is preferably made of a size having a width of about 10mm, the mesh of the vertical blocking network 26 is preferably made of a size having a width of about 7mm.

In addition, the inner mesh of the inner portion 242 of the inner tunnel net 24 is preferably made of a size having a width of about 5mm, the mesh of the inner portion 222 of the outer tunnel network 22 has a width of about 3mm It is preferable that it consists of.

The mesh of the support net 28 is preferably made of a size having the same width as the inner portion 222 of the outer tunnel network (22).

In other words, the network size of each part is listed in order of the largest size, `` outer part of cover net and outer tunnel net〉 inside of net net from inside〉 vertical blocking net〉 inside of net net from inside〉 outside of inner net and supporting net In the order of.

In the present embodiment, all the components including the cover net 20, the outer tunnel network 22, and the inner tunnel network 24, including the vertical barrier net 26 and the support net 28, are made of rubber and synthetic rubber. It is preferable that the so-called soft material, such as synthetic resin, is formed, in particular, the spaced pins 21 and 23 protruding from the cover net 20 and the outer tunnel net 22 are made of a more flexible material than the other parts.

Referring to the operation of the filter bag for the road drainage system according to the present embodiment configured as described above are as follows.

First, as shown in FIGS. 3 and 4, the contaminant filter opening 10 according to the present embodiment is seated on the grating 7, and the grating 7 is separable using a fixing means such as a fixing clip 30. Bound with

According to the contaminant filter opening 10 according to the present embodiment installed as described above, since the contaminants such as fallen leaves and plastic paper are caught on the cover net 20, the contaminants are introduced into the rain gutter 5 through the grating 7. The phenomenon does not occur. Therefore, the work of cleaning the contaminants becomes very easy.

In this case, the trapped material caught by the cover net 20 is lifted by the spacer pins 21, and since the gap is formed between the trap and the surface of the cover net 20, the trap is formed on the surface of the cover net 20. Close contact with the net prevents the phenomenon of blocking the net completely.

Therefore, even if it rains in a state where debris such as fallen leaves or plastic paper is accumulated, rainwater flows well into the rain gutter through the gap formed between the scum and the cover net 20, and the raised structure of the cover net 20 Due to the gap is formed between the grating (7) and the cover mesh 20 through which the rainwater flows into the rain gutter (5). Therefore, the phenomenon that rain water does not flow into the rain gutter 5 during rainy weather and is accumulated on the road is prevented.

On the other hand, in rainy weather, various contaminants mix with rainwater along the roadside, and the rainwater in the center of the road flows to the edge due to the gradient structure with high center and low edges. The net 22 and the inner net 24, the vertical blocking net 26, the supporting net 28 is made.

That is, bulky ones such as fallen leaves or vinyl paper among the mixed matter flowing in rainwater are preferentially filtered by the outer part 221 of the outer tunnel network 22, and the outer part 221 of the outer tunnel network 22 is small in volume. The small stones and the like that pass through the hook is caught on the outer portion 241 of the inner net 24, and likewise fine fine particles such as coarse sand passing through the outer portion 241 of the inner net 24 is a vertical barrier net ( 26).

Then, the fine sand, such as enough to pass through the vertical barrier net 26 is sequentially filtered on the inner part 242 of the tunnel network 24 and the inner part 222 of the outer tunnel network 22 from the inside of the cover net ( It is impossible to enter the 20) side, it is also filtered by the backing net (28).

Accordingly, according to the present embodiment, it is almost perfect to filter out various sizes of contaminants ranging from relatively large leaves to fine sand.

In addition, since the contaminant filter opening according to the present embodiment is made of elastic materials such as synthetic rubber and synthetic resin, each component is light and easy to separate from the grating 7, but also elastically deformed. The tires will not damage the tires if they are hit.

In particular, the spacer pins 21 and 23 protruding from the surface of the cover net 20 and the outer tunnel network 22 is made of a more flexible material so as to bend smoothly, as described above, 21) (23) in order to prevent this because the risk of puncturing the car tire is increased if the material is made of high strength.

Meanwhile, the contaminant filter opening according to the present embodiment may have various sizes, and basically, the entire area (the area formed by the outside of the tunnel network) should not be smaller than the grating 7, but the external tunnel network ( 22) and internal net 24, vertical barrier 26 are preferably the same as the size of the grating (7).

5, 6, and 7, each tunnel network 22, 24, and the vertical blocking network 26, if the size is out of the grating 7 each tunnel network 22, 24 ) And the vertical blocking net 26 is preferably provided only on three sides of the cover net 20, which is the cover net 20 without each tunnel net 22, 24 and the vertical blocking net 26 This is to ensure that one side of) is placed in contact with the boundary stone between the roadway and the sidewalk so that no interference with the boundary stone occurs.

In addition, the contaminant filter opening according to another embodiment of the present invention is provided with only the cover net 20 and one tunnel net 22 (corresponding to the external tunnel network of the previous embodiment) covering the edge of the cover net as shown in FIG. In the form of

According to another embodiment of the present invention, detailed filtering of the contaminants may be difficult because the net network 24, the vertical blocking network 26, and the support network 28 in the foregoing embodiment may be difficult. Not only the grating 7 can sufficiently overcome the phenomenon of clogging, but also has a feature that the manufacturing cost is cheaper than the previous embodiment due to its simple structure.

The contaminant filter opening according to each embodiment of the present invention may be made of a structure having a luminous paint applied to its surface at night or may have a material having luminous properties. It is helpful to improve the aesthetics of the road and the passage of vehicles or pedestrians by emitting light at night with a large number of roads arranged along the edge of the road. The traffic accident prevention effect is also great.

As described above, according to the contaminant filter opening according to the present invention, there are advantages as follows.

First, in terms of the processing of the contaminants, since most of the contaminants are filtered out of the filter spout without entering the rain gutter, the filtered state of the contaminants can be easily grasped. The efficiency is improved by cleaning the impurities, and it is possible to separate and filter the combustible contaminants such as relatively large leaves, twigs, and plastic paper, and the non-combustible contaminants such as sand, soil, etc. .

In addition, in the drainage side of the rainwater, the grating is not blocked even when a large amount of contaminants accumulates, so even when there is a lot of precipitation, such as during heavy rains, the rainwater smoothly flows into the rainwater collecting container so that the rainwater does not fall out and the road is not flooded. There is an advantage.

In addition, in terms of ease of use, there is an advantage in that the installation and separation of the filter opening is easy in view of the property that is simply mounted on the grating to be fixed by the fixing clip.
