BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage port for a retaining wall for preventing the outflow of soil on a residential site, when the residential site is being constructed.

[0002]

2. Description of the Related Art Conventionally, it is required by rules to open drain ports at regular intervals in a retaining wall. The drain port has the purpose of draining groundwater or rainwater remaining on the backside of the retaining wall and preventing the retaining wall from peeling off the site. However, in the related art, the drain port 7 provided in the retaining wall has only a pipe hole opened on the side surface of the retaining wall in order to satisfy only the function. Therefore, even if many trees and street trees are placed for the purpose of beautifying the residential area, the dwelling walls and drains are exposed as low-design shapes, so the dignity of the townscape may be reduced. is there.

[0003]

SUMMARY OF THE INVENTION The present invention is to solve the conventional disadvantage. That is, instead of exposing the drainage port 7 provided in the retaining wall U as it is, the drainage port such as a tile fired as a decorative plate is provided on the side surface of the retaining wall U at the outlet of the drainage port 7. The decorative panel 1 is attached, and the design of the drain port decorative panel 1 and the retaining wall U as a whole is improved as a contrast. Further, in order to prevent the drainage decorative plate 1 from continuing to flow along the drain and the mold and algae breeding in the drainage portion to prevent dirt or peeling, the drainage as a passage through which the slight drainage flows. The guide slits 1a and 1b are formed.

[0004]

The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described. That is, in the configuration in which the drain port decorative board 1 attached to the retaining wall U is provided at the outlet of the drain port 7 that opens to the wall surface of the retaining wall U, the drain port decorative panel 1 is configured by a fired tile, Drain guide slits 1a and 1b are provided in the vertical direction.

[0005]

Next, the operation of the present invention will be described. A ballast layer W for improving the matching of the embankment wall U with the embankment is provided on the back portion of the embankment wall U, and groundwater and drainage collect in the ballast layer W. Unless the groundwater or drainage is discharged from any drainage outlet, the groundwater and the drainage gradually accumulate, and eventually the retaining wall U is peeled off from the ballast layer W. In the present invention, the ballast layer W and the retaining wall U
A drain port 7 is provided for communication with the outside. The decorative wall 1 is attached to a portion where the drain port 7 is exposed on the surface of the retaining wall U. The drainage decorative board 1
Are provided with drainage guide slits 1a and 1b for guiding groundwater and drainage flowing in the vertical direction, and preventing the front surface of the drainage decorative panel 1 from being contaminated by the water flowing in the vertical direction. It is.

[0006]

Next, an embodiment of the present invention will be described. FIG. 1 is a side sectional view of a retaining wall U and a drain port 7, FIG. 2 is a perspective view of a retaining wall U and a drain port 7, and FIG. 3 is a retaining wall U having a vertical groove 3. FIG. 4 is a front view showing a state in which a drain-face decorative board 1 having a star-shaped design is laid, and FIG.
5 is a star-shaped design of a drain port decorative board 1
FIG.

FIG. 1 and FIG. 2 will be described. The retaining wall U is composed of a lower embedded foundation portion and an upper retaining soil portion.
Under collapse pressure. On the back side of the retaining wall U, a ballast layer W is formed, which serves to separate groundwater, rainwater and muddy soil, and retain water. In addition, the ballast layer W also has a role of improving the matching between the retaining wall U and the embankment M.

In the upper and lower retaining portions of the retaining wall U,
The drain outlets 7 are opened at regular intervals. The drain outlet 7 is required to be arranged by a rule. FIG. 2 shows an embodiment in which the retaining wall U is configured as a unit and the retaining wall U of the unit is continuously formed. However, the retaining wall U is separately formed by casting concrete on site. However, the present invention can be implemented even when the drain outlets 7 are arranged at regular intervals.

Next, referring to FIG. 3, FIG. 4 and FIG. In FIG. 3, the retaining wall U has a design in which a vertical groove 3 is formed in the side wall. A drain port 7 is opened on the line of the vertical groove 3, and the drain port decorative board 1 is attached to the drain port 7. In the retaining soil wall U, a rectangular recess 9 is formed in a portion where the drain port 7 is opened, and the drain port decorative plate 1 is attached so as to be fitted inside the square recess 9. is there. When the drainage decorative panel 1 is fitted in the rectangular recess 9 in this manner, the same surface of the drainage decorative panel 1 and the retaining wall U is formed, so that the design can be improved. .

[0010] In the present invention, a decorative hole 5 is formed at the center of the decorative panel 1 through a drain opening 17 communicating with the drain port 7, and around the decorative opening 17. doing. A star-shaped design recess 2 is formed concentrically around the drain opening decorative plate opening 17 and the makeup recess 5. The star-shaped design recess 2 has drain guide slits 1 at the top and bottom.
The upper drain guide slit 1a and the lower drain guide slit 1b form a groove in communication with a and 1b. The star-shaped design recess 2 may be of any design, but it is necessary that the recess is recessed from the surface of the drainage decorative board 1, and the drain guide slits 1a and 1b are always opened up and down. You do it.

[0011]

[Effects of the Invention] The present invention is constructed as described above, and has the following effects. That is, first, the drain port 7
By attaching the drainage decorative panel 1 made of a fired tile plate or the like to the above, it is possible to prevent the outlet portion from being worn or chipped by the drainage from the drainage hole 7.

Secondly, since the drainage decorative plate 1 laid at the outlet of the drainage opening 7 is provided with vertical drainage guide slits 1a and 1b, fungi and algae are propagated by water flowing for a long time with the chorochoro. In this case, it is possible to minimize the portion of the drain opening decorative board 1 that is stained by the mold or algae to the minimum width. If the drainage guide slits 1a and 1b are not formed, the water of the chorochoro spreads over the entire area below the drainage decorative board 1, so that a wide area of the part is stained by fungi and algae. is there. This can be prevented.
