Alternatively, the water supplied by the water supply and drainage part 60 is supplied to the vegetation part 30 through the water channel part 50.

The water channel part 50 includes a vertical tube 51 connected to the porous tube 37 of the vegetation part 30 and a horizontal tube 53 connected to the vertical tube 51. The vertical pipe 51 extends downward from the lower surface of the porous pipe 37 to discharge the water collected through the porous pipe 37 downward.

1 and 4, the horizontal pipe 53 is connected to an existing drainage path installed at both sides of the road to discharge the water drawn from the vertical pipe 51 into the drainage path.

The drainage path connected to the horizontal pipe 53 is provided with a water supply and drainage part 60 for discharging water introduced from the horizontal pipe 53 to the outside or supplying water to the horizontal pipe 53.

The water supply and drain unit 60 includes a branch valve 61 provided at one end of the horizontal pipe 53. The branch valve 61 selectively connects the horizontal pipe 53 to the water supply device 63 or the sump 65 according to a water supply and drainage request.

The water supply device 63 is configured as a pump to supply water to the horizontal pipe (53). In addition, the drain tank 65 stores water introduced through the horizontal pipe 53 and discharges the water to the outside.

Therefore, the branch valve 61 may supply or drain water to the vegetation part 30 according to the season (flood or dry season) and weather conditions.

For reference, the water supply device 63 may be configured as a bidirectional pump to supply water to the horizontal pipe 53, or may be configured to forcibly drain the water drawn through the horizontal pipe 53. Therefore, when the rainwater surges due to heavy rain, the water supply device 63 may be operated to forcibly drain the water.

6 and 7 show another embodiment of the buried track structure having the vegetation structure of the present invention. The embedded track structure shown in Figures 6 and 7 relates to an embodiment for aquatic plants such as duckweed, squirts and green grass.

In addition, the water tank 70 may be provided with a fountain 75 for forming a fountain by water supplied from the outside.

The configuration for supplying water or treating the discharged water to the vegetation portion 30 composed of a water tank configured as described above is the same as mentioned above.

Hereinafter, the operation of the buried track structure having a vegetation structure according to the present invention having the configuration as described above in detail.

The buried track track structure of the present invention operates differently depending on the flood and the dry season. First, in the case of a flood, rainwater falling onto the upper surface of the vegetation part 30 is introduced into the purification layer 40 through the planting layer 45.

Rainwater introduced into the purification layer 40 is purified by the functional treatment layer 41 and collected into the porous pipe 37 through the drainage layer 43. At this time, the absorbent body 31 absorbs rainwater flowing from the upper portion and collects it into the porous tube 37.

Rainwater collected by the porous pipe 37 is introduced into the water supply and drainage part 60 through the vertical pipe 51 and the horizontal pipe 53. At this time, the branch valve 61 of the water supply and drainage part 60 connects the horizontal pipe 53 to the drainage tank 65 so that water introduced through the horizontal pipe 53 is collected in the drainage tank 65 to the outside. To drain.

However, when the amount of rainwater surges due to heavy rain, the branch valve 61 may be forced to drain the rainwater temporarily by connecting the water supply device 63 and the horizontal pipe 53.

In the case of the buried track structure according to the second embodiment of the present invention, as described above, the rainwater flowing into the water tank 70 is collected in the drain tank 65 and drained to the outside.

On the other hand, in the case of the dry season, water is intermittently supplied to the vegetation part 30 through the water supply and drainage part (60). The branch valve 61 of the water supply and drainage part 60 connects the horizontal pipe 53 and the water supply device 63, and the water supply device 63 supplies water.

Therefore, the water supplied by the water supply device 63 is supplied to the vegetation part 30 through the water channel part 50 and the porous pipe 37. At this time, the absorbent body 31 connected to the porous tube 37 absorbs the water supplied from the porous tube 37, and the water absorbed by the absorbent body 31 has insufficient water due to capillary action. 30 are supplied to the soil.

In the case of the embedded track track structure according to the second embodiment of the present invention, the water supplied by the water supply device 63 may be introduced into the water tank 70 in the water harvesting device as described above.

In the scope of the basic technical spirit of the present invention, many modifications are possible to those skilled in the art, and the scope of the present invention should be interpreted based on the claims which will be described later. .
