Description

[Detailed explanation of the invention] This invention has a large number of water collecting pipes protruding from the side of the main pipe, a water collecting pipe is fitted into the water collecting pipe, and the water collected by the water collecting pipe is buried underground. The present invention relates to a connection member for facilitating connection between a water collection pipe and a main pipe in a water collection device that collects water in a main pipe for drainage.

The present inventor first 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 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, fix the water collector 1 through the ribs 9, 9.
0, and its tip (the right end in Figure 1) is inserted into the end opening of the water collection pipe 12 as the narrow part 11, and the unnecessary gap except for the collection channel 6 is filled as shown in Figure 3. It is closed by a packing 13.

This water collector 10 has a main pipe 14 as shown in FIG.
It is fitted into a large number of water collection pipes 12 connected to each other so as to protrude from the side surface of the pipe, and is buried underground and used for underground drainage. That is, the water that flows through the surfaces of the water guide plates 1, 2, 3, and 7 or collects in the center of the water collector 10 by capillary action enters the water collection channel 6 through the slits 4 and 8, and flows from the water collection pipe 12. It flows into the main pipe 14 and is discharged. A large number of water collection devices can be buried in wetlands, playgrounds, embankments, and other places where it is desired to quickly drain underground water that has increased due to rainfall, allowing drainage over a wide area.

It is convenient for this water collection device to be manufactured from synthetic resin such as vinyl, and in order to facilitate transportation, conventionally the water collection device 10 is separated and the main pipe 14 and water collection pipe 12 are welded and attached at the factory. The water collector 10 was then transported to the site in a state where the water collector 10 was installed there. This is because the water collector 10 and the main pipe 12 can be fitted reliably because the fitting length can be increased, but the water collection pipe 12 and the main pipe 12 can be fitted securely.
4 is based on the common sense consideration that due to the thickness of the main pipe 14, it must be welded to support the water collection pipe 12.

However, when attempting to bundle a large number of main pipes 14 with water collection pipes 12 protruding laterally for transportation,
The water collection pipe 12 gets in the way and makes it difficult to tie up. Furthermore, even if the materials are bundled, the volume becomes large and the bundles tend to collapse during transportation, which is an inconvenience.

The present invention aims to avoid such inconveniences, and provides a connecting member that allows the water collection pipe 12 and the main pipe 14 to be transported separately and joined together on site.

Next, the present invention will be explained with reference to embodiments shown in FIG. 5 and below.

The connecting member 15 for the water collection device is made of soft vinyl chloride, and is manufactured in an almost cylindrical shape, with inner and outer diameters becoming slightly smaller toward the lower part, and wall thickness becoming thinner at the lower part in FIG. 5. The protrusions 16 and 17 are formed so as not to be located on the same radius of the cylinder. The protrusion 16 on the inner surface is high at the lower end, becomes lower as it goes upward, and has a height of zero at the upper end. The protrusion 17 on the outer surface is high at the upper end, becomes lower as it goes downward, and ends at a position slightly below the center of the length of the connecting member. The cross section of the protrusion is triangular, but other shapes are also possible.

To attach the water collection pipe 12 to the main pipe 14 using this connecting member 15, as shown in FIG.
The connecting member 15 is inserted into the hole 18 opened in the side surface of the connecting member 15 with the thin end facing into the main pipe to below the protrusion 17 on the outer surface, and the water collection pipe 12 is fitted into the connecting member 15. When the water collecting pipe 12 is pushed into the connecting member 15, the fitting gradually becomes firmer due to the protrusions 16 on the inner surface of the main pipe 14 that become higher inward, so that the connecting member 15 is pushed into the hole 18. , the thickness of the connecting member 15 is the hole 1
8 is thicker toward the outside of the hole 18, and the protrusion 17 on the outer surface is also higher toward the outside of the hole 18. Therefore, as the water collection pipe 12 is pushed in, the connecting member 15 is also pushed in to an appropriate position, and the connection member 15 is also pushed into the hole 18. The water pipe 12 is reliably connected to the main pipe 14.

Since the internal protrusions 16 and 17 are crushed by the pressure at the time of fitting, no gap is created between the water collection pipe 12 and the hole 18. However, in view of its properties as a water collection device, there is no problem even if there is a small gap, and in some cases, this gap can be easily closed with an adhesive.

When the water collection pipe 12 and the main pipe 14 are connected through the connecting member in this way, the water collection pipe 1
By changing the angle of the water collecting pipe 12 and pushing the water collecting pipe 12 together in that state, the installation angle of the water collecting pipe can be slightly adjusted.

In this way, both pipes can be connected by simply inserting the lower part of the connecting member 15 into the hole 18 of the main pipe and pushing the water collection pipe 12 into the connecting member 15, making it easy to connect both pipes on site. When transporting to the site, only the main pipe 14 can be bundled together, and the water collection pipe 12 and the water collector 10 can be transported together separately, making it possible to transport the main pipe 14 extremely efficiently. There is no need to weld the water collection pipes and main pipes, which has the great effect of reducing production costs.
