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 previously invented a water draining device that can drain water efficiently (Japanese Patent Application No. 114110/1982).

That is, as shown in FIGS. 1 and 2, a plurality of flat water guide plates 1, 2.3 are arranged with a narrow gap 4 between the inner edges of adjacent plates.
．． 4 is fixed radially through ribs 5, 5, and below that, a water guide plate 7 having a Y-shaped cross section and a collection channel 6 at the upper end is attached to the upper end and the lower surface of the water guide plates 2, 3, respectively. With gaps 8 and 8 provided between them, it is fixed via ribs 9°9 to form a water conductor 13, and its tip (the right end in FIG. The backing 12 is inserted into the end opening of the backing 12, and unnecessary gaps except for the water collection channel 6 are closed with a backing 12 as shown in FIG.

When such a drainage device is buried in the soil, in order to prevent the joint between the water collection pipe 11 and the narrow portion 10 from being damaged due to twisting or distortion caused by uneven pressure in the soil, Just by lightly inserting the narrow portion 10 into the water collection pipe 11, the joint portion is made flexible.

For this reason, at a civil engineering work site, the work of burying the drainage device in the soil involves supporting the device with your hands to prevent the water conductor 13 from falling out of the water collection pipe 11 and keeping it in the proper position while burying the water drainage device in the soil. It's a pain to have to call.

Once the water guide body 13 is removed from the water collecting pipe 11, the water draining device becomes completely useless.

The purpose of the water draining device of the present invention is to eliminate the above-mentioned inconveniences and provide a water draining device that can be easily installed on site.

The water draining device of the present invention consists of water guiding plates 1.2, 3.7 and ribs 5.
．． By making the joint between the water guide body 13 and the water collecting pipe 11 made of a screw joint, the above-mentioned disadvantages can be solved and the backing 12 can be made unnecessary.

The present invention will be described in more detail below with reference to the drawings showing embodiments.

In the first embodiment shown in FIG. 4, reference numeral 14 denotes a fan-shaped plate whose outer periphery is approximately in the shape of a quarter circular arc, which is fixed to the narrow part 10 at the tip of the water guide body 13. Four water guide plates are installed, and the water guide plate 1 and the water guide plate 2, the water guide plate 2 and the water guide plate 7, the water guide plate 7 and the water guide plate 3, and the water guide plate 3 and the water guide plate 1 are connected by closing the respective gaps, In the narrow portion 10, the ribs 5 and 9 are replaced.

A small hemispherical protrusion 15 is formed in the center of each of the four plates 14 on the outer peripheral surface thereof, and is integrally formed with the plate 14. A locking step portion 16 having a hook-shaped cross section is formed on the inner surface of the end portion over the entire circumference of the inner surface.

The inner diameter a (FIG. 5) of the locking step portion 16 is formed to be slightly smaller than the diameter of the circumscribed circle of the small projections 15, 15 of the plates 14, 14 fixed to the water guide body.

In order to connect the water guide plate 13 and the water collection pipe 11 configured as described above, the narrow part 10 of the water guide body 13 is strongly pushed into the water collection pipe 11 as shown by the arrow hole in FIG. Plate 1
The small protrusions 15.15 formed on 4 and 14, while elastically deforming, climb over the locking step 16 on the inner surface of the water collection pipe and reach the step 16.
The water guide body 13 enters the inside of the water guide body 13 and recovers its original shape after entering.
This prevents water from being drawn out from the water collection pipe 11.

At this time, the small protrusions 15.15 are formed as small as possible to the extent that they are difficult to pull out from the water collection pipe 11 even if the water guide body 13 is pulled, so that the water guide body 13 and the water collection pipe 11 are loose and flexible. It is connected in a state where it is connected.

As shown in FIG. 5, the water collection pipe 11 is buried in a conch notebook wall 17 on the edge of a cliff to drain water accumulated inside the wall.
As shown in Figure 6, a large number of water collection pipes 11 and il are connected to the main
A large number of water collection bodies 13, 13 are connected to the branch-like structure to drain water from a large area such as a ground.

FIG. 7 shows a second embodiment of the present invention, in which the first embodiment shown in FIG. , 7, 2.3 is shown.

Other configurations and operations are the same as in the first embodiment.

Since the water draining device of the present invention is constructed as described above, there is no need to support the water conducting body 13 by hand and cover it with soil to prevent it from falling off from the water collecting pipe 11 when burying it, and the burying work in the soil can be simplified. This makes it easier and allows the work to proceed quickly, which is practically effective.
