Description

[Detailed description of the invention] The present invention relates to a drainage device that is buried in the soil and drains water contained in the soil, and which drains water efficiently and is easy to implement. This is what we intend to provide.

The present inventor first invented a water draining device that can drain water efficiently (Japanese Patent Application Laid-open No. 47314/1983). That is, as shown in FIGS. 1 and 2, a plurality of flat water guide plates 1, 2, 3 are arranged with ribs 5, 5 with gaps 4, 4 provided between the inner edges of adjacent plates. A water guide plate 7 having a Y-shaped cross section and a water collection channel 6 at the upper part is provided below the water guide plate 7 with gaps 8 and 8 between the upper end and the lower surface of the water guide plates 2 and 3, respectively. In this state, it is fixed via ribs 9, 9 to form a water draining device 10, and in use,
The narrow part 11 at the tip is inserted into the water collection pipe 13, and the water collection pipe 13 is buried in the soil with unnecessary gaps except for the part of the water collection channel 6 closed with packing 12.
Therefore, the water above the water draining device 10 passes through the side surfaces of the vertical water guide plate 1 and the upper surfaces of the water guide plates 2 and 3 and is collected into the collection channel 6 through the slits 4 and 4, while the water below is channeled. After dew condenses on the lower surfaces of the plates 2 and 3 or the side surfaces of the water guide plate 7, it travels along the surface and is collected in the collection channel 6 through the slits 8 and 8, and is discharged to the outside through the water collection pipe 13.

The present invention relates to an improvement of the water draining device according to the previous invention, which is constructed and operates as described above, and provides a water draining device that can improve water collection efficiency and simplify connection to a water collection pipe. This is what I am trying to do.

Hereinafter, the present invention will be explained with reference to drawings showing embodiments.

Fig. 3 is a cross-sectional view similar to Fig. 2 showing an embodiment of the present invention, and Fig. 4 is a side view seen from the left side of Fig. 3 with the water guiding plate 2 and ribs 5 and 9 omitted. . The lower end of the vertical water guide plate 1 is branched into a substantially inverted Y shape, forming a space 14 facing the collection channel 6 at the upper part of the lower water guide plate 7. In addition, the upper vertical water guide plate 1, the left and right water guide plates 2, 3, and the upper ribs 5, 5
means the lower edge of the vertical water guide plate 1 and the left and right water guide plates 2,
It is integrally molded from synthetic resin with a narrow gap 4, 4 provided between it and the inner edge of 3. As shown in detail in FIG. 5, a semi-cylindrical portion 16 having a stepped portion 15 in the middle is formed at the front end portion (right end portion in FIG. 4) of each of the water guide plates 1, 2, and 3. On the other hand, the lower water guide plate 7
The ribs 9 and 9 are similarly integrally molded from synthetic resin, and a semi-cylindrical portion 16a having a stepped portion 15a in the middle is formed at the front end, as shown in detail in FIG. A small protrusion 17 as shown in FIG. 6 is protruded from the upper surface of the rear end of the lower water guide plate 7.
At the rear ends of the upper water guide plates 1, 2, and 3, there is formed a seat 18 having a small hole in the lower surface into which the small projection fits.

In order to combine the members configured as described above to form a water draining device, the upper surfaces of the lower ribs 9, 9 are connected to the left and right sides while the small protrusion 17 is fitted into the small hole on the lower surface of the seat portion 18. It is brought into contact with the lower surfaces of the water guiding plates 2 and 3, and both surfaces are adhered by means such as adhesive or welding. In this state, the two semi-cylindrical parts 16, 16a at the front end are combined into a cylindrical shape, and there is a slit-shaped gap 19 between the lower edge of the upper semi-cylindrical part 16 and the upper edge of the lower semi-cylindrical part 16a. is formed. In FIG. 4, 20 is a protrusion protruding from the lower surface (or upper surface) of the base of one semi-cylindrical portion 16 (or 16a);
It comes into contact with the upper surface (or lower surface) of 6a (or 16). Therefore, the gap 19 is elastically bent about the protrusion 20, and the diameter of the cylindrical portion at the tip also changes. Alternatively, the protrusion 20 may be omitted and the gap 19 may be configured to flex with the rib 9 closest to the tip (the rib at the right end in FIG. 1) as a fulcrum.

Since the water draining device of the present invention is configured and assembled as described above, a space 14 having a relatively large volume is provided above the slits 4 and 8 that introduce water into the collection channel 6.
As the air in the space expands and contracts, air always passes through the gaps 4 and 8, and the gaps 4 and
8 is less likely to become clogged, and water collection efficiency is always maintained at a good level. Furthermore, the work of connecting the water draining device to the piping is extremely easy and quick, as it is only necessary to push the cylindrical part formed by the semi-cylindrical parts 16, 16a into the open end of the piping while elastically reducing the diameter. can be done.
