The present invention relates to a rainwater infiltration gutter structure that is built along a roadside to perform rainwater storage and drainage functions together, and can prevent falls and tripping accidents by securing visibility.

Contrary to the decrease in the ratio of farmland to forest due to industrialization and urbanization, as the area occupied by buildings and pavement of roads (asphalt or concrete pavement) expands, the ground penetration rate of rainwater decreases. As environmental problems such as land, water quality, and air have emerged due to the destruction of the rainwater circulation system, the need for rainwater management is becoming increasingly important.

As for the technology for rainwater utilization, the permeable block technology group to meet both the demand for ground pavement and the need for rainwater penetration, the storage tank technology group to store and utilize the rainwater that is buried underground, and the rainwater storage tank made of permeable materials There is a group of infiltration storage tank technologies that allow the stored rainwater to slowly infiltrate into the ground with a time difference.

In addition, various technologies related to blocks, panels, precast members, etc. for constructing rainwater storage tanks or infiltration storage tanks are known.

However, there is a limit to the capacity of the storage tanks buried underground, and there are many cases where rapid drainage of rainwater is required rather than penetrating the ground during heavy rains (urban areas, roadside, etc.). Therefore, it is required to provide a technical solution that can satisfy both the incompatible "necessity of rainwater storage and ground penetration" and "necessity of rapid drainage of rainwater during torrential rain".

In addition, it is required to prepare a technical solution for securing visibility to prevent a fall or trip accident due to an infiltration gutter installed on the roadside for a vehicle drainage function.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention is a linear structure constructed by continuously disposing a flat block 100 for rainwater storage and drainage installed and erected with a porous material in the ground along a roadside, and the rainwater storage-drainage The flat block 100 includes a bottom portion 11, sidewall portions 12 formed on both sides of the bottom portion 11, a middle floor portion 13 provided across the middle of the sidewall portion 12, and the a block body portion 10 including a partition wall portion 14 formed between the bottom portion 11 and the middle floor portion 13; An upper space portion 20 formed so that the upper end of the middle layer bottom portion 13 is open; a lower space portion formed under the middle floor portion 13 and longitudinally divided by the partition wall portion 14; and a water passage groove (40) formed in the longitudinal direction on the front or rear surface of the middle layer bottom part (13); It is configured to include, and the drainage channel 120 is formed by the junction of the upper space part 20, the storage tank 130 is formed by the junction of the lower space part 30, and the rainwater storage-drainage that connects The flat block 100, two water passage grooves 40 are combined to form a water passage 140, and a fluorescent or photoluminescent finish cap 170 is installed along the upper end of the side wall portion 12. Visibility, characterized in that It provides a secured heavy rain disaster prevention type multi-stage rainwater infiltration gutter structure (200).

The rainwater storage-drainage flat block 100 is made of a porous material to ensure water permeability, and the heavy rain disaster prevention type multi-stage rainwater infiltration side gutter structure 200 provided by the present invention is constructed by placing a plurality of them upright and connecting them. do.

The block body part 10 is configured to include a bottom part 11 , a side wall part 12 , the middle layer bottom part 13 , and a partition wall part 14 .

An upper space portion 20 having an open upper end is formed on the middle layer bottom portion 13 . That is, the upper space portion 20 is an open space in which the upper surface of the middle floor portion 13 becomes the floor surface, the upper section of the side wall portion 12 becomes the wall surface, and the ceiling is open.

A lower space portion 30 is formed under the middle floor portion 13 . That is, in the lower space part 30, the upper surface of the bottom part 11 becomes the floor surface, the lower section of the side wall part 12 becomes the wall surface, and the lower surface of the middle floor part 13 becomes the ceiling surface. to be.

A partition wall portion 14 is formed between the bottom portion 11 and the middle floor portion 13 to longitudinally divide the lower space portion 30 . The bulkhead portion 14 serves as an intermediate support wall of the middle floor portion 13, so the structural role increases when the left and right widths of the flat block 100 for rainwater storage-drainage are wide, and the rainwater storage-drain A plurality of the partition wall portions 14 may be formed according to the width of the accommodating piece-shaped block 100 .

In addition, by forming the inner wall surface of the side wall portion 12 as an inclined surface 12-1, the vertical cross-section of the upper space portion 20 may be formed in a V-shape (see [Fig. 1] above).

A water passage groove 40 is formed in the longitudinal direction on the front or rear surface of the middle layer bottom part 13 . When the flat block 100 for rainwater storage-drainage is erected and placed in contiguous arrangement, the two water passage grooves 40 of the adjacent flat block 100 are connected to each other so that they can be combined into one water passage 140 ( [Fig. 3]). The water passage groove 40 may be formed to communicate in each divided section of the lower space 30 in the upper space 20 .

A longitudinal rainwater penetration groove 50 may be formed on the front or rear surface of the bottom portion 11 . The rainwater penetration groove 50 is preferably formed so as not to vertically communicate with the water passage groove 40 formed in the middle layer bottom part 13 .

The outer wall side of the side wall portion 12 may further include a lifting hook portion 60 provided in the form of a groove or a chin.

Specific details regarding the rainwater penetration groove 50 and the lifting hook 60 will be described later.

As described above, the heavy rain disaster prevention multi-stage rainwater infiltration gutter structure 100 is constructed by continuously arranging the flat block 100 for rainwater storage-drainage to connect. Accordingly, the drainage channel 120 is formed by the junction of the upper space part 20 , and the storage tank 130 is formed by the junction of the lower space part 30 . The rainwater storage tank 130 is segmented into a compartment by the partition wall portion 14 of the flat block 100 for drainage, as shown in FIG. 2 .

During heavy rain, rainwater is primarily introduced into the drainage channel 120 , and secondly flows into the storage tank 130 through the water passage 140 . Rainwater flowing into the storage tank 130 is stored for a certain period of time, but since the flat block 100 for rainwater storage-drainage is made of a porous material, the stored rainwater gradually passes through the bottom 11 with a time difference to be buried in the ground. will penetrate Of course, since the middle-layer bottom part 13 is also formed of a porous material as a part of the flat block 100 for rainwater storage-drainage, a portion of the rainwater of the drainage channel 120 passes through the middle-layer bottom part 13 and passes through the storage tank. (130) is introduced.

In addition, by forming the inner wall surface of the side wall part 12 as an inclined surface 12-1, so that the vertical cross-section of the drainage passage 120 is formed in a V-shape, rainwater flowing down the road surface is transferred to the inclined surface 12-1. ) can lead to inflow.

On the other hand, when the rainwater penetration groove 50 is formed in the longitudinal direction on the front or rear surface of the bottom part 11, and the flat block 100 is erected and arranged in a contiguous arrangement, the adjacent rainwater storage-drainage flat block 100 The two rainwater penetration grooves 50 of the can be configured to be combined into one rainwater penetration hole 150 by being connected to each other. In this case, while the rainwater stored in the storage tank 130 penetrates the bottom 11 as a whole and penetrates into the ground, a concentrated penetration section through the rainwater penetration hole 150 is formed. However, it is preferable that the rainwater penetration hole 150 is formed in a portion that is not in vertical communication with the water passage 140 so that the ground is not digged by falling water.

Meanwhile, by installing a filter 145 in the water passage 140 , rainwater flowing into the storage tank 130 may be filtered. The filter 145 may be managed by periodic cleaning or replacement.

A change occurs in the function of the multi-stage rainwater infiltration gutter structure 200 provided by the present invention depending on whether the filter 145 is installed.

When the filter 145 is not installed, the rainwater introduced into the drain 120 once flows into the storage tank 130 through the water passage 140 . In this case, the heavy rain disaster prevention multi-stage rainwater infiltration gutter structure 200 preferentially performs a rainwater storage function, so that the stored rainwater slowly permeates into the ground during normal times. In the case of heavy rain exceeding the temporary rainwater storage capacity of the storage tank 130 , rainwater from the storage tank 130 overflows through the water passage 140 and is drained along the drainage channel 120 .

When the filter 145 is installed, there is no significant difference between the amount of rainwater permeation per unit area-hour through the filter 145 and the amount of rainwater permeation per unit area-hour through the middle layer bottom 13 made of a porous material. have. In this case, the multi-stage rainwater infiltration gutter structure 200 preferentially performs a drainage function, and as the inflow rainwater is drained along the drainage channel 120 , a part of the middle-level floor 13 or filter 145 is used. It is introduced into the storage tank 130 through the. Even in the case of heavy rain, the drainage function is prioritized, and since some of the rainwater being drained flows out to the storage tank 130 , the drainage capacity is relatively increased by the amount of the discharge.

On the other hand, according to the continuous arrangement of the flat block 100 for rainwater storage-drainage, the lifting hook 60 provided in the form of a groove or a chin is also continuously connected.

The flat block 100 can be individually moved in the vertical direction by inserting a grip on the lifting hook 60 during construction or maintenance and repair of the multi-stage rainwater infiltration gutter structure 200 .

In addition, in the present invention, a fluorescent or photoluminescent finish cap 170 is installed along the upper end of the side wall portion 12 . The closing cap 170 may be installed in units of the flat block 100 for rainwater storage-drainage, but as shown in [Figs. - It is efficient to install to cover the top of the flat block 100 for drainage.

The closing cap 170 may be made of a fluorescent or photoluminescent material, or may be manufactured by applying a fluorescent or photoluminescent material to the outer surface.

The closing cap 170 is composed of a length member having an ∩-shaped cross section, and in a state where it is fitted on the top of the side wall part 120, the side wall part 120 and the closing cap 170 by the frictional force of the inner surface can be made to be fixed.

In addition, as shown in [Fig. 1], by forming an insertion groove 70 in the transverse direction on the side wall part 120, and forming a locking protrusion inside the end of the closing cap 170 having an ∩ cross-section, the It can be configured so that the installation state of the closing cap 170 is maintained by the groove-chin combination of the insertion groove 70 and the locking jaw.

The closing cap 170 performs a safety bar function to prevent a fall accident of an automobile or bicycle, a fall accident of a pedestrian, etc. by clearly revealing the boundary line of the rainwater penetration side. In particular, it may contribute to ensuring nighttime visibility by the fluorescent or photoluminescent material.

On the outer surface of the closing cap 170, guide phrases/symbols, advertisement texts/figures, etc. may be displayed.

In the above, the present invention has been described in detail along with specific examples. However, the present invention is not limited by the above embodiments and may be modified and modified without departing from the gist of the present invention. Accordingly, the claims of the present invention cover such modifications and variations.
