In general, a collection well is buried on road surfaces such as urban roads or parks to discharge rainwater or sewage to a sewage treatment plant or river. In such a collecting well, as the walls and the floor on all sides are integrally formed, a connection pipe is formed on one wall to connect the sewage pipe buried underground, and a wide open space is formed on the upper part so that a large amount of rainwater can quickly flow in. is formed, and a grid-type grating is installed in the open space.

Such a grating is installed at the entrance of a sewer at the edge of the road or at the upper part of an exposed drain to facilitate drainage of rainwater.

However, in the grating as described above, as the interval between vertical bars for filtering foreign substances is usually formed to be about 4 to 5 cm, foreign substances having a size of 4 cm or less pass through the grating and flow into the collecting well, so that tobacco contained in rainwater or sewage water Various foreign substances such as butts and other small garbage, fallen leaves, and gravel enter the collecting well and river as they are, and become the main culprit of environmental pollution. There was a problem with this.

As such, there is a problem in that foreign substances deposited in the drainage canal or collection well are decayed, and odors are generated in the drainage passage or the collection well.
