Description

Urban Anti-Clog Rainwater Gutter and Its Construction Method

The present invention relates to a rainwater drain and a construction method thereof, and more particularly, to a rainwater drain for preventing clogging in an urban area and a construction method thereof, which forms a drainage hole on one side of a road curbstone of a size into which an end of a grating can be inserted, and when the grating is placed on a main body, an auxiliary wing of the grating is automatically raised to be positioned inside the drainage hole of the road curbstone, thereby increasing drainage efficiency by allowing rainwater to drain through the drainage hole of the road curbstone when foreign matter is caught in the grating and preventing smooth drainage of rainwater, and prevents the occurrence of safety accidents in advance by preventing the feet of pedestrians from getting stuck in the drainage hole of the road curbstone.

Generally, a sump is a structure installed on roads or other facilities in urban areas to collect rainwater or cleaning water (hereinafter referred to as "rainwater") and discharge it into a river or surrounding drainage channel. In addition, a conventional sump includes a main body formed by digging a hole in the ground or pavement surface and constructing an inner wall to collect rainwater, a drainage pipe connected to the main body and connected to a river or surrounding drainage channel, and a grating installed on the upper part of the main body to form a support surface for pedestrians and vehicles and filter foreign substances contained in the rainwater.

The main body of the above-mentioned sump is generally formed by pouring concrete mortar into the inner wall of a recessed portion dug from the ground to form a space for collecting rainwater. In addition, the drain pipe is connected to the circumference of the main body, and the bottom surface of the drain pipe is arranged higher than the bottom surface of the main body, so that rainwater flowing into the main body is collected from the bottom surface of the main body, and when the water surface of the rainwater rises above the bottom surface of the drain pipe, it is discharged along the drain pipe. In addition, the grating is made of a metal material so as to be able to support the weight of pedestrians or vehicles passing by the sump, and is manufactured in the shape of a strainer so as to be able to filter foreign substances contained in rainwater, and is installed on the upper part of the main body.

These collection systems have a problem in that foreign substances contained in the rainwater flowing on the road gradually accumulate on the grating, clogging the grating and causing water to pool on the road.

To solve these problems, domestic patent publication No. 10-2025-0008498, a road rainwater drainage device that allows drainage from a curbstone, and domestic patent registration No. 10-1563695, a road curbstone for drainage treatment, are disclosed.

The above road rainwater drainage device is installed around the road adjacent to the boundary block (5) as illustrated in FIG. 1, and includes a sump (10) having an opening formed at the top, a storage space for storing rainwater formed inside, and a drainage pipe (17) connected thereto for discharging rainwater flowing into the storage space to the outside; a grating (20) installed in the opening of the sump (10) to filter out foreign substances contained in rainwater flowing into the storage space through the opening; a bypass block (30) installed between the boundary blocks (5), having an inlet formed on one side facing the road so as to allow rainwater to flow inward, and a drainage hole formed downwardly through the bottom of the inlet; a bypass pipe connecting the drainage hole and the sump so as to transfer rainwater flowing into the inlet to the sump; a rainwater detection sensor installed in the inlet or the drainage hole to detect the inflow of rainwater; It is provided with a light emitting unit (60) installed in the above-mentioned bypass block and which emits light when rainwater is detected by the above-mentioned rainwater detection sensor; and a wireless communication unit which wirelessly transmits rainwater detection information detected by the above-mentioned rainwater detection sensor to the outside.

However, these road rainwater drainage devices have inlets formed in the bypass blocks, so there is a risk of safety accidents such as slipping when moving a vehicle after parking it on the road. In addition, since two or more gratings must be installed separately, there is a problem in that the construction cost and construction time increase.

The road curb stone for the above drainage treatment is constructed on the boundary line of the road and the sidewalk as shown in Fig. 2, and has an opening (111) formed on the front surface facing the road, a drainage hole (113) formed on the bottom surface, a settling groove (110a) formed on the upper surface into which a stone panel (110b) is inserted, and a coupling hole (112) and an operating hole (178) formed on both sides of the opening (111), a drainage pipe (130) connected to the drainage hole (113) and connected to a drainage channel, and a drainage hole (141b) connected to and communicating with the opening (111) are formed, and a catch groove (141c) and a catch projection (141a) inserted into the coupling hole (112) are provided, and a coupling groove (141e) and a handle (141d) are provided. It includes a mounting frame (141), a cover member (143) that is pressed into a connecting groove (141e) to cover a drainage hole (141b) and has a plurality of cut-outs (143a) formed so that the opening (111) is opened when the wire mesh of the drainage ditch is blocked and rainwater collects in front of the water collecting case (110), and a plurality of cut-outs (143a) are formed, and a breakage prevention hole is formed at the end of the cut-outs (143a), a detachable member (150) that is caught and connected to a catch-out groove (141c) when a catch-out projection (141a) is inserted to restrain the mounting frame, and a release member (170) that releases the restraint state of the detachable member (150) by operation of a worker to separate the mounting frame (141) from the water collecting case (110).

However, these road curbs for drainage treatment have the problem of increasing construction costs and time because gratings must be installed on the road and curbs respectively.

Referring to FIGS. 4 to 9, the urban clog-prevention rainwater catchment (100) according to the present invention is composed of a body (110), a sewage catchment (120), a road curbstone (130), and a grating (140).

First, the body (110) is formed of one of PC concrete, metal, and synthetic resin, has an open upper surface, a step (111) is formed on the inner edge, and at least one drain is formed at the bottom. For example, in the drawing, an inlet (113) and a drain (115) are shown on both sides of the bottom, and one may be formed on the bottom or bottom side. At this time, a rainwater pipe (P) is installed at an angle and connected to the inlet (113) and the drain (115).

The body (110) is formed with a first inclined surface (117) that is inclined inwardly on one side of the upper edge to allow rainwater to drain to a location corresponding to the drainage hole (131) of the road curbstone (130), and an inclined support protrusion (119) is provided on the first inclined surface (117) to support the auxiliary wing (143) of the grating (140) by rotating it.

In addition, the waste receiver (120) is formed of one of PC concrete, metal, and synthetic resin, and is formed in the same shape as the container (110) so as to be in close contact with the inside of the container (110) and collect foreign substances inside the container (110). At this time, it is preferable that the waste receiver (120) has a hole (121) of the same diameter formed at a position corresponding to the inlet (113) and drain (115) of the container (110).

The sewage receiver (120) is formed with a second slope (123) that slopes inward on one side of the upper edge so that rainwater can be drained at a location corresponding to the drainage hole (131) of the road curb (130), and a hole (126) through which a slope support step (119) passes is provided in the second slope (123).

It is preferable that the waste receiver (120) be provided with a lifting means (127), such as a handle or a hook, so that it can be discharged from the body (110) and cleaned.

In addition, the road curb (130) is made of stone or synthetic resin material, and is positioned on one upper surface of the container (110) so that rainwater flowing in laterally through the upper surface of the container (110) is drained, and a drainage hole (131) is formed connecting one side surface and the bottom surface. At this time, the road curb (130) is installed continuously along the roadside, and it is preferable that the drainage hole (131) is formed only in the road curb (130) at the location where the container (110) is formed.

In addition, the grating (140) has a main wing (141) formed in multiple stages in the direction of the road width, an auxiliary wing (143) positioned between the main wing (141) at one end, and a rotation shaft (145) to which each auxiliary wing (143) is fixedly connected while penetrating the main wing (141) and the auxiliary wing (143) in the direction of the road length, and is mounted on a step (111) of a body (110), and when mounted on the body (110), the auxiliary wing (143) protrudes within a drainage hole (131) of a road curb (130) to drain rainwater into the drainage hole (131) of the road curb (130) and prevent pedestrians from tripping.

The auxiliary wing (143) is formed in a square plate shape with a metal material, and has an axial hole (143a) formed at one end to be fixedly coupled to a rotation shaft (145), and a third inclined surface (144) formed so that the other end maintains a vertical plane when raised and fixed on the inclined support step (123) of the waste receiver (120). At this time, it is preferable that the auxiliary wing (143) be formed with a length that does not interfere with the drainage hole (131) of the road curb (130) when raised.

In addition, the auxiliary wing (143) has an angle limited by the inclined support jaw (123) of the waste receiver (120), and depending on the selection, it can be maintained in the same line as the main wing (141), or it can be installed in a form in which it goes backwards with the vertical line as the center by increasing the rotation angle.

Meanwhile, the urban clog-prevention rainwater catcher (100) according to the present invention may have an inclined support step (125) formed on the second inclined surface (123) of the sewage catcher (120) as shown in FIGS. 10 and 11. FIG. 10 is a perspective view showing the configuration of an urban clog-prevention rainwater catcher according to another embodiment of the present invention, and FIG. 11 is a cross-sectional view taken along line B-B of FIG. 10.

Hereinafter, the installation process of the construction method of the urban area clog-prevention rainwater drain according to the present invention will be described in detail with reference to the attached drawings.

First, a trench is created in the drainage section between the road and the sidewalk, and aggregate is laid on the bottom of the trench to form a settlement prevention layer.

In this state, a rainwater pipe (P) is installed in the trench, and the body (110), the sewage collector (120), and the grating (140) are installed so that the grating (140) is positioned at regular intervals, and the rainwater pipe (P) is connected to the inlet (113) and the drain (115) of the body (110). At this time, the grating (140) is installed by being placed on the step (111) of the body (110), and when lowered by its own weight, the auxiliary wings (143) located at both ends come into contact with the inclined support step (119), and the rotation axis (145) rotates, and as a result, the entire auxiliary wings (143) rotate around the axis and the ends rise, thereby partially blocking the drainage hole (131) of the road curb stone (130) to be installed later, thereby preventing pedestrians from getting tripped.

When the installation of the hull (110), the waste receiver (120) and the grating (140) is completed, the outside of the hull (110) and the outside of the rainwater pipe (P) are backfilled with soil, and then concrete is poured into the remaining drainage section except for the part of the hull (110) where the grating (140) is installed.

When the curing of the concrete is completed, a road curb (130) is installed for the sidewalk and boundary, and a road curb (130) with a drainage hole (131) formed therein is installed on the grating (140) at the location of the body (110).

Afterwards, construction is completed by completing the road and pavement.

When only replacing an existing installed sump, the existing sump is replaced, and only the body (110), road curbstone (130), and grating (140) according to the present invention are replaced.

Therefore, if foreign substances such as fallen leaves or trash are caught in the grating (140) and drainage is not smooth, causing rainwater to flow horizontally to the outside of the road, the rainwater is discharged through the drainage hole (131) of the road curb stone (130).

In addition, when the grating (140) is installed on the body (110), the auxiliary wing (143) automatically rises, blocking the lower part of the drainage hole (131) of the road curb (130), thereby preventing a pedestrian's foot from getting stuck.

Furthermore, when cleaning the inside of the body (110), the waste receiver (120) can be raised to clean the inside of the waste receiver (120) and then reassembled to increase cleaning efficiency.

In addition, during the rainy season, such as the monsoon season, the grating (140) can be rotated 180° so that the auxiliary wing (143) is positioned toward the road, thereby completely opening the drainage hole (131) of the road curbstone (130) to improve drainage capacity and prevent road flooding in advance.

The present invention is capable of various modifications and takes many forms, and the detailed description of the invention has described only specific embodiments thereof. However, it should be understood that the present invention is not limited to the specific forms described in the detailed description, but rather encompasses all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
