Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage pipe which is buried in a place where drainage is required, such as artificial turf or ridges in a field, and induces drainage, and a buried structure of the pipe.

[0002]

2. Description of the Related Art Conventionally, as a drainage pipe or a drainage attraction pipe, a synthetic resin pipe provided with a large number of attraction holes has been known and is used everywhere.

It is also known that a part of the drain pipe is provided with blade members for attracting and feeding water.

[0004]

However, the above-mentioned conventional drainage-induction pipe cannot be said to have a sufficient drainage effect simply because it has a hole for attracting water, especially along the blade member. The drainage efficiency of the flowing water was extremely low.

It is an object of the present invention to cope with the above-mentioned drawbacks and to provide a good drainage attracting action by specifying the arrangement of the drainage hole of the drainage pipe to improve the drainage effect.

[0006]

In order to meet the above-mentioned object, the drainage guide pipe of the present invention has a vane member extending in the longitudinal direction on both sides of a synthetic resin pipe having a predetermined length and extending obliquely upward from both sides from the lower part. Along with the installation of a plurality of laterally elongated holes on both sides of the pipe at appropriate intervals over the lengthwise direction and shifting the vertical position toward the attraction direction, further on the inner surface of the blade member, A plurality of small holes are formed on both sides of the lower part of the pipe in the longitudinal direction at appropriate intervals.

[0007] When the drainage inducing pipe is buried in the ground, a structure in which bean gravel is filled and arranged around the pipe above the blade member is adopted.

[0008]

The drainage inducing pipe of the present invention is buried in the ground below the ground surface, such as a field ridge or an artificial turf structure.
When the water is drained, water is normally attracted to the inside of the pipe evenly through horizontally elongated holes that are vertically out of phase, and is drained through the pipe. Along the bottom of the blade member, the water flows downward and is attracted by the small holes formed near the root of the lower blade member to further enhance the drainage effect. Therefore, the drainage attraction performance is better than that of a drainage pipe that is simply provided with an attraction hole.

When buried in the ground, bean gravel is arranged around the pipe to prevent the pipe from being clogged and to improve the drainage attracting function.

[0010]

Embodiments of the drainage guide pipe and the buried structure of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view of the pipe of the present invention, and FIG. 2 is a sectional view of the pipe.

In these figures, reference numeral 1 is a synthetic resin pipe having a required length, and the diameter is not always constant depending on the embedding place, but a pipe with a diameter of about 10 cm is generally used, and the length of the pipe is on both sides. Horizontally elongated holes 2 having a required length are vertically provided in two steps at appropriate intervals in the vertical direction in the attracting direction, that is, in the obliquely downward direction with the vertical position being shifted.

Of course, the number of upper and lower stages is not limited to two, and three or more stages may be provided.

The length and interval of the laterally elongated holes are determined in accordance with the vertical displacement, but at this time, it is most preferable that they partially overlap each other. However, if the distance between the horizontally long holes is too long, the effect of inducing the angle is reduced.

The drainage inducing pipe is further provided with a blade member 3 extending obliquely upward on both sides over the length of the pipe at a lower portion of the pipe 1, and the pipe length is provided on a pipe wall near a root on the inner side. Small holes 4 for invitation are formed at appropriate intervals in the direction.
It is effective to drill the small holes 4 in the direction of the attraction so as to improve the attraction.

The blade member 3 is a member that extends to the left and right and is a pipe 1.
However, as shown in FIG. 3, a separate blade member may be fixed at the lower portion of the pipe 1 and extended obliquely upward on both sides. , 15 to 45 °, preferably 15 to 30 °. If the inclination is too large, the efficiency of attracting water is low, and the same applies if the inclination is too small.

On the other hand, if the small holes 4 referred to above are too close to the central portions on both sides of the pipe, the effect of inducing water induced by the blade members 3 is weakened, so that the base position near the lower end of the pipe 1 is as good as possible. Is.

The small holes 4 are not limited to one step, and it is of course effective to provide two or more steps along the base of the blade member 3.

FIGS. 3 and 4 are views showing the state where the drainage inducing pipe 1 of the present invention is buried inside a ridge 5 or the like.
2 are the same as those in FIG.

In FIG. 3, the drainage inducing pipe shown in FIGS. 1 and 2 has the blade member 3 extending to the left and right integrally fixed to the pipe 1, while the pipes fixed to the left and right are attached. In addition, beans gravel 6 is filled and arranged around the pipe 1 above the blade member 1 and buried underground G.

The soybean gravel 6 is arranged around the pipe 1 in order to prevent clogging of the pipe 1 when attracting water in the ground G and to make the attracting action effective.

FIG. 4 shows a state in which the drainage-inducing pipe 1 is buried in the ground of a cultivated field in which ridges 5 are formed on the ground surface, and the water attracted in the direction of the arrow is the horizontally elongated hole of the pipe 1. 2. It is drawn into the inside of the pipe 1 through the small hole 4 in the lower part, and is sent through the inside of the pipe to the existing drainage point which is installed in advance.

At this time, since the laterally long holes 2 and the small holes 4 are formed in the direction in which water is attracted, the attracting action is very good.

Although the attraction effect is affected by the depth of the burial, it is generally buried at about 30 cm below the ground surface, at a depth of about 5 m when buried below, and at about 35 cm below the ground. In some cases, an attractive effect is observed over a range of about 6 m.

Of course, attraction is not performed below the blade member 3 in the horizontal direction.

Thus, the water in the ground which is attracted by the above-mentioned attracting pipe of the present invention passes through the inside of the pipe and the drainage action is performed at any time.

[0027]

As described above, according to the present invention, the blade members extending obliquely upward are provided on both sides of the synthetic resin pipe, and the pea gravel is arranged in the periphery to be embedded. Water is guided along and promotes the attracting action by the drainage pipe, and the pipe has horizontal holes on both sides that are arranged in the attracting direction by shifting the vertical position, so that the attracting water is uniformly attracted along the length direction. Has the advantage that Moreover, since the small holes are provided near the base of the blade member, the water guided by the blade member is surely drained through the small holes.

Further, since the pebble is arranged around the periphery of the pipe, clogging of the pipe hole does not occur, and the attracting action is very reliable.

[0029] Therefore, the drainage operation can be performed much more reliably than a pipe having a simple induction hole on the entire surface, and the drainage function is improved.
