Description

Drain board for road surface rainwater drainage system}

The present invention is a drain board for a road surface rainwater drainage system that is installed at the boundary of the roadway for road surface drainage and is configured to quickly and smoothly drain rainwater that falls on the road, and a gutter constructed to maximize road surface drainage characteristics by the drain board. It's about structure.

At the side edge of the road or at the boundary between the sidewalk and the roadway, side ditches are continuously buried along the longitudinal direction of the road to form drainage ditches, that is, ditches, for discharging rainwater that falls on the road surface. In addition, separate water collection wells are buried at appropriate intervals (e.g., about 20 to 25 meters on a typical road) along the ditch line formed by continuously connecting side ditch pipes along the ditch formation line, and the water collection well is connected to a sewer pipe. . Therefore, rainwater that falls on the road surface flows into the gutter pipe at the edge of the road, flows through the gutter pipe, collects in a water collection well, and then flows into the sewer pipe.

The side ditch pipes are continuously buried along the length of the bottom of the road edge, and are closed by installing grating or a concrete cover at the upper opening of the side ditch pipes.

Figure 1 is a diagram showing a general gutter shape and water stagnation phenomenon. As shown in Figure 1, in the form of a gutter, a gutter section covered with concrete is formed at a certain width along the road boundary stone, and water collection gratings, which are water collection holes, are installed at predetermined intervals (e.g., 20 meters) along the longitudinal direction of the gutter section. there is. The water collection grating may be a water collection hole for sending rainwater down to the gutter water pipe in a conventional general L-shaped gutter, and is described in Prior Documents 1 and 2 (Registration No. 10-1509202, Registration No. 10-1822899). It may be a grating that forms the inlet of the surface water inflow hole of the side-mounted water collection well disclosed in .

However, in actual roads, depending on the topography or construction conditions, the surface of the gutter section is curved or there is a difference in height along the length of the road, and because neighboring catchment gratings maintain spacing, there is a certain point in the middle of the catchment section. Rainwater may accumulate.

Therefore, the present applicant has applied for and registered Prior Document 3 (Registration No. 10-2184981) for smooth drainage function. Prior document 3 allows rainwater to flow smoothly even in the gutter sections between catch basins, while effectively directing the inflow rainwater to the catch basin, thereby maximizing road surface drainage characteristics to enable rapid and smooth drainage and utilization of rainwater that falls on the road. The construction of an eco-friendly gutter structure with improved road surface drainage characteristics is being disclosed.

Referring to prior literature 3, the passage forming plate in the side gutter structure is formed with a plurality of protrusions and functions to provide a passage for rainwater to flow through the space between the protrusions.

However, the passage forming plate disclosed in Prior Document 3 is mostly composed of plastic molded products, and when constructing such a passage forming plate, the protrusion forming one surface of the passage forming plate may be distorted. Then, due to problems such as the degree of protrusion of the protrusion being lowered or damaged, the rainwater passage becomes narrow or blocked, thereby hindering or blocking the flow of rainwater.

Therefore, even with the structure of the passage shape plate disclosed in Prior Document 3, the problem of not completely resolving the phenomenon of rainwater falling on the road surface being unable to be discharged and continuing to pool may still occur.

Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings.

Figure 2 is a perspective view of a side gutter structure according to an embodiment of the present invention, Figure 3 is a plan view of Figure 2, Figure 4 is a front view of Figure 2, and Figure 5 is a cross-sectional view taken along line A-A of Figure 4.

Referring to Figures 2 to 5, the gutter structure 100 of the present invention is formed along the boundary stone 110 at the edge of the road, and rainwater that falls on the road surface flows toward the boundary stone 110 and the gutter structure at the edge of the road. do.

The present invention proposes a structure that allows rainwater flowing into the gutter structure to be quickly discharged over the entire length of the gutter.

The boundary stone 110 is installed continuously along the longitudinal direction of the road at the boundary between the sidewalk 2 and the roadway, and a support wall 112 may be formed below the boundary stone 110.

In the gutter structure of the present invention, water collection wells (1) are buried at intervals along the longitudinal direction of the gutter. The water collection well (1) includes a water collection tube (10) that is closed around the bottom and sides, open at the top, and provides a water collection space (10a) where rainwater collects, and a cover (20) that covers the upper part of the water collection tube (10). Includes.

Although not shown, a rainwater pipe connection hole for connecting a rainwater pipe of a sewage facility is formed on the side wall of the water collection pipe 10. A storm water pipe connector is a hole for connecting a discharge pipe to a sewage facility. For example, connect a stormwater pipe to a stormwater pipe connector, and connect the stormwater pipe to a stormwater main pipe that passes under the road. Then, the rainwater collected in the sump drains into the stormwater main pipe through the rainwater pipe connected to the stormwater pipe connector.

The cover 20 is formed with a surface water inlet hole 22 that allows rainwater to flow in from the surface of the road pavement layer and a seepage water inlet hole 24 that allows rainwater infiltrated below the road pavement layer to flow in. The entrance of the permeating water inlet hole 24 is covered with a grill-shaped cover 24a.

An inflow neck structure 30 is built around the surface water inlet hole 22. And a grating 32 is installed on the upper part of the inflow neck structure 30. The inflow neck structure 30 can be formed in the field by piling concrete around the surface water inflow hole 22 on the upper surface of the water collection well 1. Alternatively, as shown in the embodiment shown in the drawing, it can be constructed by installing metal or plastic materials in the form of pipes or ducts. Made in the form of a metal or plastic pipe or duct, concrete for forming an inlet is poured around the surface water inflow hole 22 at the site, and the lower part of the inflow neck structure 30 is buried in the poured concrete and fixed. can do.

A soil or floor compaction layer 130 and a concrete support layer 140 are poured between the water sump 1 and the water sump 1. The concrete support layer 140 may be poured at a height such that its surface matches the upper surface of the water sump 1. Accordingly, rainwater can flow between the upper surface of the concrete support layer 140 and the upper surface of the water collection well (1). That is, rainwater can flow over the upper surface of the concrete support layer 140 and flow into the infiltration water inlet hole 24 formed on the upper surface of the water collection well (1).

According to the present invention, the drain board 200 for a road surface rainwater drainage system is constructed to cover the water collection well 1, the upper surface of the concrete support layer 140, and the side of the boundary stone 110 to a certain height. When the drain board 200 is constructed as described above, a passage through which rainwater can flow is formed on the water collection well 1, the upper surface of the concrete support layer 140, and the side of the boundary stone 110 by the drain board 200. .

Additionally, non-woven fabric 300 may be further installed on the drain board 200, and side-groove finishing concrete 150 is poured on the drain board 200 and the non-woven fabric 300. The non-woven fabric 300 is used to protect the drain board 200 by covering it before pouring the gutter finishing concrete 150. That is, the non-woven fabric 300 prevents foreign substances from being swept into the drain board 200 in the gap between the boundary stone 110 and the side finishing concrete 150, and also prevents foreign substances such as sand from being swept into the water sump 1. It is to prevent this. Since foreign substances are filtered by the non-woven fabric 300, high-quality water can be stored in the water collection well (1), thereby securing high-quality groundwater. In addition to the nonwoven fabric 300, a fine mesh structure, etc. may be used.

The side finishing concrete 150 is formed to match the height of the grating 32. It is desirable to calculate the height of the drain board 200 in advance after pouring the drain board 200 so that the top of the drain board 200 is located slightly lower than the upper surface of the drain finished concrete 150.

In this way, a drain board 200 is constructed on the upper surface of the sump 1, that is, the upper surface of the cover 20 and the side of the boundary stone 110, and the side finishing concrete 150 is poured on the drain board 200. am. Therefore, rainwater that falls on the road surface flows over the gutter finishing concrete (150), and some of it enters the surface water inflow hole (22) of the water collection well (1) through the grating (32). And the rainwater that flows over the gutter finishing concrete 150 and flows down to the boundary stone 110 flows down through the passage space of the drain board 200 between the side of the boundary stone 110 and the gutter finishing concrete 150. Rainwater that goes down along the drain board 200 on the boundary stone 110 side flows along the upper surface of the water collection well (1) and the upper surface of the concrete support layer 140, and flows through the infiltration water inlet hole (24) of the water collection well (1). ) is entered.

Next, we will look at the structure of the drain board 200.

Figure 6 is a plan view of the drain board installed in the gutter structure of the present invention, and Figure 7 is a front view of Figure 6.

The drain board 200 shown in FIGS. 6 and 7 is in a state before being installed on the gutter structure 100. The completed drain board 200 is constructed on the upper surface of the water collection well 1, the upper surface of the concrete support layer 140, and the side of the boundary stone 110. The completed drain board is shown in (e) of FIG. 8 and will be described in detail below.

According to the present invention, the drain board 200 has a size that sufficiently covers the area to be constructed in the gutter structure 100, and can be made of plastic.

The drain board 200 includes a first plate 210 on which a plurality of protrusions 212 are formed and a concave groove 214 is formed on the opposite side by the protrusion of the protrusions 212, and the first plate 210 A second plate 220 extends in one direction and is bent about one side of the first plate 210 to contact the end surfaces of the protrusions 212 of the first plate 210 and cover all of the protrusions 212. It is composed including.

The length L2 of the second plate 220 is slightly longer than the length L1 of the first plate 210 so that the second plate 220 can be bent and cover the protrusion 212 of the first plate 210. It is desirable to be formed long.

In this way, if the first plate 210 and the second plate 220 are manufactured to overlap each other in the unfolded state, a passage space through which rainwater flows can be formed between them. There is, and the drain board 200 with the passage space formed in this way is constructed.

Figure 8 is a process diagram showing the manufacturing process of the drain board installed in the gutter structure of the present invention.

The manufacturing process of the drain board 200 in FIG. 8 is a drain board before manufacturing including the first plate 210 and the second plate 220, the upper surface of the water sump 1 and the concrete support layer 140, and the boundary stone ( This is a process of creating a shape that can be installed on the side of 110), and can be viewed as a process of manufacturing an approximately 'ㄴ' shaped drain board 200.

In order to make the drain board 200, the first plate 210 and the second plate 220 are unfolded as shown in (a) of FIG. 8, and the protrusion 212 of the first plate 210 is formed. Bend the second plate (220) by 90°. At this time, there may be a method of making the first plate 210 by bending it.

The state in which the second plate 220 is bent 90° is shown in (b) of FIG. 8, and in this state, the first plate 210 is bent 90° in the direction of the arrow based on line a. Then, in FIG. 8 ( It has the same shape as c), and in this case, in (c) of Figure 8, H is the height constructed on the side of the boundary stone 110, and W is the width constructed on the upper surface of the sump 1 and the concrete support layer 140. This can be. Therefore, the bent portions of the first plate 210 and the second plate 220 may vary depending on the sizes of H and W.

Next, an operation is performed to bring the protrusion 212 formed on the first plate 210 into contact with one surface of the second plate 220. That is, in Figure 8 (c), a part of the second plate 220 is bent in contact with the protrusion 212 of the first plate 210 as shown in Figure 8 (d), and in the state of Figure 8 (d) The second plate 220 is folded again so that the remaining surface of the second plate 220 is in contact with the remaining protrusion 212 of the first plate 210.

When all of these processes are completed, a drain board having a shape that can be installed on the upper surface of the water collection basin 1 and the concrete support layer 140, and the side of the boundary stone 110, as shown in (e) of FIG. 8 (200) is completed. In (e) of FIG. 8 , an open concave groove is formed on one side of the drain board 200, and the other side is closed by the second plate 220. Due to this overlapping structure of the first plate 210 and the second plate 220, a passage space 230 through which rainwater flows is formed between the first plate 210 and the second plate 220.

In addition, since the second plate 220 supports the passage space 230 in the completed drain board 200, even when concrete is poured after constructing the drain board 200 on the side structure, the drain board 200 remains intact. The protrusion 212 can maintain its original intact state without being distorted. Therefore, rainwater that falls on the road surface will flow smoothly and unhindered through the passage space 230 secured between the first plate 210 and the second plate 220, avoiding the protrusions 212.

Figure 9 is a view showing the state in which the drain board according to the present invention is installed on a road side ditch.

Referring to Figure 9, a drain board 200 is constructed on the upper surface of the water sump 1 and the side of the boundary stone 110, and the drain board 200 may be covered with a non-woven fabric 300. Then, the side finishing concrete (150) is poured.

And when the side hole finishing concrete 150 is poured on the drain board 200, the concrete enters the concave groove 214 formed in the first plate 210 of the drain board 100, and the drain is drained according to the hardening process of the concrete. The board 200 is integrated with the side finishing concrete 150.

Meanwhile, the second plate 220 in contact with the protrusion 212 of the first plate 210 can support the passage space 230 formed between the first plate 210 and the drain board 200. Even if pouring work such as concrete is performed after construction, the passage space 230 can be preserved without being damaged. As a result, the discharge function of rainwater can be maximized without being degraded.

In this way, in the present invention, rainwater flows inside up to a certain height on the upper surface of the concrete support layer 140 poured between neighboring water collection basins (1), the upper surface of the water collection basin (1), and the side of the boundary stone (110). A drain board 200 on which a passage space 230 is formed is constructed, and side opening finishing concrete 150 is poured on the drain board 200. Therefore, rainwater that flows over the gutter finishing concrete 150 and flows to the boundary stone 110 flows along the passage space 200 of the drain board 200 constructed between the side of the boundary stone 110 and the gutter finishing concrete 150, The infiltration water flows into the collection space (10a) through the infiltration hole (24) of the collection well (1).

In the present invention, the specifications of the drain board compared to the gutter structure can be determined as follows. However, this is just one embodiment and it is natural that it can be designed in many different ways.

In the gutter structure of the present invention, assuming that the width and height of the boundary stone 110 are 180 mm * 150 mm, the width and height of the gutter structure 150 are 500 mm * 200 mm, and the height of the concrete support layer 140 is 200 mm, etc. , L1 of the first plate 210 may be 580 mm, L2 of the second plate 220 may be 600 mm, the diameter of the concave groove may be 100 mm, the spacing between the concave grooves may be 7 mm, and the protrusion length of the protrusion may be 10 mm. The widths of the first plate 210 and the second plate 220 are variable.

As described above, the present invention is described with reference to the illustrated embodiments, but these are merely illustrative examples, and those of ordinary skill in the art to which the present invention pertains can make various modifications without departing from the gist and scope of the present invention. It will be apparent that variations, modifications, and equivalent other embodiments are possible. Therefore, the true scope of technical protection of the present invention should be determined by the technical spirit of the appended claims.
