The present invention relates to a bridge water collecting device installed on the edge of the bridge top plate so that the discharge of various wastes contained in the initial rainwater during the rain is structurally blocked so that only filtered rainwater having a relatively low risk of contamination can be discharged. The various inflows of dirt are sequentially filtered by the filters installed in the upper water flow plate and the lower pollutant collecting container, so that only rainwater with relatively low risk of contamination can be discharged to the drain pipe of the bridge. It relates to a bridge water collecting device having a pollution prevention function by the initial rain so that it can be structurally prevented.

In general, the bridge water collecting device, which is installed on the bridge top plate and drains the incoming soil with rainwater, is installed on both edges of the bridge top plate mainly covered with concrete slab and ascon pavement. Landfills, which are made of collecting devices, are reclaimed so that rainwater flowing into the catchments can be discharged to rivers or rivers through drain pipes connected to the bottom of the bridge. Such a water collecting port is formed by fastening a grating cover in which rainwater inlets are formed on the upper side of the opening.

Of course, the upper side of the catchment is located on the same line as the upper side of the concrete slab below the inclined ascon pavement of the bridge deck, and the rainwater flowing along the ascon pavement passes through the rainwater inlet of the grating cover and naturally flows into the catchment body below. It was structure that could be. In addition, the drain pipe connection portion, which is the lower side of the catchment, is fastened to the upper side of the drain pipe having a relatively large diameter, and is normally sealed by rubber packing and connected by fixing bolts.

However, in the conventional water collecting device for bridges, since the grating cover on the upper side of the catchment body is formed in a flat shape, the smaller one than the rainwater inlet hole of various wastes and foreign substances introduced with rainwater at rainwater can pass. This could not be introduced into the catchment body but continued to accumulate on the grating cover to cover the grating cover at some point, which could lead to a blockage that prevents rainwater from entering the catchment body through the grating cover.

This eventually caused the rainwater to pass through the grating cover and was not normally discharged to the drain pipe under the catchment body, so that the rainwater was flooded on the top of the bridge and flooded, resulting in the inconvenience and the safety accidents that resulted in enormous obstacles in the traffic passage.

On the other hand, the structure of the grating cover is improved to be inclined so that rainwater can be more easily introduced into the catchment body through the grating cover, but various wastes included in the initial rainwater flowing into the catchment body during the rainfall are different. Not only was it discharged into the river or river through the drainage pipe without filtration treatment, but it was a direct cause of pollution, and various wastes flowing through the grating cover into the catchment body accumulated in the catchment body. There was a structural problem that prevented or blocked.

As a result, the existing water collecting device for bridges is not polluted with various pollutants accumulated on the ground such as tire dust, heavy metal oil, and contaminants. Inevitably, it caused the destruction of the environment.

Therefore, the present invention was invented to solve the above problems, and the various wastes introduced with rainwater during rainfall are sequentially filtered and retained by a plurality of filters respectively installed on the upper water flow plate and the lower pollutant collecting container. Only rainwater with a relatively low risk of contamination can be discharged to the drain pipe below the catchment body through these filters, so that water collection for bridges with pollution prevention function due to the early rainwater can structurally prevent the occurrence of contamination by the dirt contained in the early rainwater. The object is to provide a device.

Furthermore, the bridge water collecting device having the pollution prevention function by the initial rainwater of the present invention has a relatively small amount of grating cover and a water flow plate without sequentially passing through a plurality of filters when rainwater continues to flow in large quantities. There is a more advanced purpose in that even a large amount of dirt can be filtered out so that it can flow directly into the drain pipe through the central part of the catchment body, thereby structurally preventing the rainwater from flowing back toward the catchment body.

In order to achieve the above object, a water collecting device for a bridge having an anti-pollution function by the initial rainwater of the present invention has a plurality of rainwater inflows on an upper side of a catchment body installed at both edges of a bridge top plate covered with concrete slab and ascon pavement. In the bridge water collecting device is provided with a grating cover formed through the ball and the drain pipe connecting portion protruding the drain pipe connected to the lower side of the water collecting body, the primary filter is mounted to filter the dirt contained in the rainwater flows first Multi-stage filter including a secondary filter and a tertiary filter so that the water flow plate installed below the grating cover and the dirt contained in the rainwater passing through the primary filter of the water flow plate are filtered again and remain without being passed through again. While forming the large-capacity inlet so that the overflow of the large flow into the gap space with the water flow plate It is configured to include a contaminant collecting container.

In particular, the contaminant collecting container is detachably equipped with a multistage filter including at least a secondary filter and a tertiary filter, sequentially mounted in both the vertical direction and the horizontal direction, or selectively mounted in at least one of the vertical direction and the horizontal direction. In addition, the grating cover has a flow plate catching jaw so that the body catching jaw protrudes from the upper side to be seated at the upper end of the catchment body, and the water flow plate located at the upper periphery of the primary filter is seated at the lower inside. Is formed to protrude.

Furthermore, the water flow plate is characterized by a technical relationship between the inner portion is formed to be inclined at an angle toward the center so that rainwater can flow into the outer primary filter.

Hereinafter, with reference to the drawings of the preferred embodiment will be described in detail the configuration and operation of the bridge water collecting device according to the present invention that can structurally prevent contamination by the dirt of the initial rainwater.

1 illustrates a plurality of filters 14, 16, and 18 that constitute a multi-stage filter as a whole according to a basic embodiment of the present invention. The water flow plate 30 and the contaminant collecting container 40 below the grating cover 20 are illustrated in FIG. ) Shows a cross-sectional structure of the water collecting device for the bridge constituting the water collecting body (10) is installed in the filter mounting portion 44 of the), Figure 2 is a grating cover 20 constituting the water collecting device according to the present invention 3A and 3B are lateral directions of the grating cover 20 in which the water flow plate 30, to which the primary filter 14 is mounted, is assembled at the bottom of the multistage filter according to the present invention. The cross-sectional structure and the AA line cross-sectional structure of FIG. 3 are respectively shown.

4 and 5 illustrate the water flow plate 30 and the contaminant collecting container 40 constituting the water collecting device according to the present invention, in particular, the water flow plate 30 is a primary filter 14 The water permeation hole 36 is penetrated so that the rainwater filtered while passing through the primary filter 14 passes through the outside of the filter support end 32 to be mounted to be dropped into the pollutant collecting container 40 below. In the case where a large amount of rainwater flows in at the same time while flooding, the rainwater flows into the outside of the filter support end 32 instead of passing through at the time of normality (when a small amount of rainwater flows into the upper portion). There is a water backflow hole 34 is formed so that it can flow into the central portion of the spout body 10 naturally penetrated immediately discharged.

In addition, the contaminant collecting container 40 includes a multistage filter such that at least a second and a third filtration step may be performed, including a first filtration step of rainwater by the primary filter 14 of the water flow plate 30. The filter mounting portion 44 is formed inside the secondary filter 16 and the tertiary filter 18 so that the secondary filter 16 and the tertiary filter 18 can be detachably mounted. Particularly, the rainwater is discharged through these secondary filters 16 and 18. In this way, a plurality of water permeable holes 46 are formed to penetrate through the filter to be filtered and finer. Of course, the filter mounting portion 44 of the inner side is also naturally formed water permeable hole 46.

In addition, FIG. 6 is a shape change so that the water flow plate 30 to which the primary filter 14 is mounted is located above the contaminant collecting container 40 without being assembled to the lower portion of the grating cover 20 as another embodiment of the present invention. The cross-sectional structure of the water collecting device for a bridge is shown.

First, the water collecting device for a bridge having a pollution prevention function by the initial superiority of the present invention is also basically an upper side of the water collecting body 10 installed on both edges of a bridge top plate usually covered with concrete slab 52 and ascon pavement 50. A grating cover 20 having a plurality of rainwater inlet holes 22 penetrated therein is installed, and the lower side of the catchment body 10 protrudes from the drain pipe connection part 12 to which a drain pipe of the bridge (not shown) is connected. Of course. This is because rainwater can not escape the configuration relationship that flows into the catch body (10) through the rainwater inlet 22 of the grating cover 20 and discharged into the river or river below the bridge through the drain pipe connection portion 12 to be.

In the water collecting device for bridges of the present invention, the grating cover is disposed so that dirt contained in rainwater flowing through the grating cover 20 can be more finely filtered as a plurality of purification steps without being directly discharged through the water collecting body 10. It is configured to be able to install a plurality of filters 14, 16, 18 in the lower part of the 20 and the catchment body 10, respectively.

That is, in the basic embodiment of FIGS. 1 to 4, the water flow plate 30 to which the primary filter 14 is mounted is configured such that the primary filter 14 is located directly under the grating cover 20. It is installed, the water flow plate 30, the rainwater passing through the rainwater inlet hole 22 of the grating cover 20 does not fall directly to the center portion through which the water collecting body 10 penetrates the outer primary filter 14 The inner part is formed to protrude at an angle to the upper side so as to flow toward the center. Particularly, as described above, the water filter hole 36 penetrates through the primary filter 14 so that the rainwater passing through the primary filter 14 passes through the primary filter 14 to fall into the pollutant collecting container 40. The protruding portion is formed with a water backflow hole 34 so that when a large amount of rainwater flows in at the same time, it flows into the central portion of the catchment body 10 naturally penetrated and immediately discharged.

In addition, the grating cover 20 is a body catching jaw (24) protruding to the outer side so as to be seated on the upper end of the catchment body 10, the water in which the primary filter 14 is located in the upper periphery at the lower inner side Flow plate catching jaw 26 is formed to protrude so that the flow plate 30 can be caught. Of course, in the application structure of the water flow plate 30 is not assembled to the lower portion of the grating cover 20, as shown in the application embodiment of FIG. The flow plate catching jaw 26 protruding from the lower inner side of the grating cover 20 for seating the gripping cover may be omitted, and the overall structure of the grating cover 20 is also applied to the water flow plate 30 according to the embodiment. Of course, it can be appropriately modified.

In addition to the water flow plate 30 on which the primary filter 14 is installed, a multi-stage filter including at least a secondary filter 16 and a tertiary filter 18 is additionally installed so that the dirt contained in the rainwater is more reliably. So that the second and third filters 16, 18 are mounted in the vertical and horizontal directions through the filter mounting portion 44 so as to filter the contaminant collecting container 40 to the inside and outside of the catchment body 10. It is composed.

In particular, the upper side of the contaminant collecting container 40 forms a large-capacity inlet 42 in which a gap between the water flow plate 30 and the predetermined space of the grating cover 20 is maintained, which collects the contaminant during a large amount of rainfall. The large amount of rainwater flowing into the cylinder 40 may overflow to the inner space of the filter mounting portion 44 inside the second and third filters 16 and 18 through the large capacity inlet 42. Of course, the pollutant collecting container 40 is a filter mounting portion in which these multi-stage filters are mounted so that relatively clean rainwater through the second and third filters 16 and 18, which are multi-stage filters, can be discharged to the drain pipe below the water collecting body 10. Numerous water permeable holes 46 are formed at 46.

In other words, the bridge water collecting device of the present invention is basically only the rainwater having a relatively low risk of contamination as the dirt contained in the initial rainwater is filtered by a plurality of filters 14, 16, 18, which constitute a multi-stage filter as a whole. Sequentially discharged, and in the case of a large amount of rainfall can be naturally discharged to the river or river through the catchment body (10), so as to prevent structural backflow to the bridge, at least three stages of the filter (14) (16) (18) are configured to be installed in the upper space and the lower space of the catchment body in which the grading cover 20 is located. Of course, the multi-stage filter of the present invention can be applied to the filter structure in more than four stages more than the three-step filter 14, 16, 18, it is preferable to apply a filter of about three stages in the functional structure of the water collecting device.

And while the inflow direction of the initial rainwater flowing through the grating cover 20 passes through the primary filter 14 and the secondary filter 16 and 18 sequentially, dirt contained in the rainwater is structurally sure. The water flow plate 30 protruding obliquely upward from the central portion is configured to be filtered, and also a large-capacity inlet 42 of a predetermined space so that the rainwater with the water flow plate 30 overflows a large amount of rainwater. Contaminant collecting container 40 forming a) is configured. In addition, the secondary filter 16 and the tertiary filter 18 mounted on the pollutant collecting container 40 are basically installed in order in both vertical and horizontal directions, but in some cases, vertical or horizontal directions. It may be selectively mounted in only one of the directions.

As shown in the inflow direction of the rainwater in FIG. 6, the bridge water collecting device of the present invention configured as described above has the primary filters 14 and 2, which are included in the initial rainwater during rainfall when a relatively small amount of rainwater flows in. It can be naturally filtered by the tertiary filter 16, 18 and remain naturally in the pollutant collecting container 40, and of course, only the relatively clean rainwater from which the dirt is filtered through the internal space inside the pollutant collecting container 40. It can be discharged to the drain pipe below the bridge.

And rainwater that flows out through the large-scale inlet 42 of the upper side of the pollutant collecting container 40 is discharged through the filter 16, 18 of the pollutant collecting container 40 is increased so much discharged In case of rainfall in which a large amount of rainwater flows in, the rainwater overflows from the upper water flow plate 40 at the same time with the overflow of rainwater through the large-capacity inlet 42. It can be discharged, it is possible to structurally prevent the occurrence of rain storm back to the bridge top plate through the upper grating cover (20).

As described above, the bridge water collecting device having a pollution prevention function by the initial rainwater according to the present invention has a plurality of dirts flowing into the rainwater rainwater at the top and a plurality of pollutant collecting vessels respectively installed on the upper water flow plate and the lower. Only rainwater that is filtered out sequentially by the filters and which has a relatively low risk of contamination can be discharged to the drain pipe below the catchment body through these filters to structurally prevent contamination by dirt contained in the initial rainwater.

In addition, if the rainfall continues and the rainwater flows in large quantities, the grating cover and the water flow plate are filtered through the grating cover and the water flow plate without passing through a plurality of filters sequentially, and flow directly into the drain pipe through the central part of the catchment body. By making it possible to be able to structurally prevent the phenomenon that the rainwater flows back toward the catchment body can also be provided.
