Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a perforated plate with a drainage groove for absorbing and eliminating underground water, which is the source of landslides, and a water absorption groove.

[0002]

[Prior art]

 As shown in FIG. 34, the conventional porous plate water absorption groove has a structure in which a water absorption hole Y 1 for absorbing underground water is provided close to the bottom of the water groove Z.

[0003]

[Problems to be solved by the device]

 In the conventional porous plate water absorption groove as described above, the underground water introduced into the water groove Z through the water absorption holes Y flows in the water groove Z, but at this time, the water is absorbed. When the groundwater level rises, a backflow phenomenon occurs, in which the water flows out from the water intake hole Y to the outside of the groove.

The present invention provides a novel water absorption groove for a perforated plate with a drain groove, which solves the above problems.

[0005]

[Means for Solving the Problems]

 According to the present invention, in a required drainage groove having side walls (or side plates) on both sides, both or one of the side walls (or side plates) is provided with a water absorption hole, and the water absorption hole 1d is formed in the drainage groove. A perforated plate with a drainage groove, characterized in that it is configured to form a flowing water groove portion Q at the bottom portion of the drainage groove by arranging it at a predetermined height P above the bottom portion of the drainage groove. It relates to the water absorption groove. The present invention aims to solve the above-mentioned conventional problems based on the adoption of such a configuration.

[0006]

[Action]

 The underground water is guided from the water absorption holes provided on the side wall into the groove, and the underground water guided into the groove flows in the flowing water groove portion Q and is guided to a predetermined place, for example, sewage or a river, and is discarded. Since the water absorption hole is located above the bottom of the drainage groove by a predetermined height P, the underground water once absorbed into the groove from the upper part of the water absorption hole is discharged from the bottom of the drainage groove. It is prevented that it overflows and escapes to the ground again from below the water intake hole.

[Effect of device]

 According to the present invention, in a required drainage groove having side walls on both sides, a vertically long water absorption hole is bored on both or one of the side walls, and the water absorption hole is formed at a predetermined height from the bottom of the drainage groove. Since the flowing water groove Q is formed at the bottom of the drainage groove by arranging the hole P upward and drilling it, extremely stable drainage of the absorbed underground water is performed.

That is, according to the present invention, since the water absorption hole is formed at a predetermined height P above the bottom of the drainage groove, the water absorption hole is once made to absorb water from the upper portion of the water absorption hole. This will often prevent the underground water from overflowing from the bottom of the drain and escaping into the ground from the lower part of the water intake hole.
