JP2012241508A - Refuse removal device of vertical drainage passage - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a device for easily removing refuse, which flows down through a vertical drainage passage, from the vertical drainage passage without use of human power.SOLUTION: A refuse removal device, which is attached to a vertical drainage passage, comprises a screen part which is attached in the vertical drainage passage and which separates drainage water and refuse, and a lateral removal part which is attached onto the vertical drainage passage and which automatically discharges the refuse out of the vertical drainage passage by making the drainage water push the refuse accumulated in the screen part.

Description

  It is an object of the present invention to provide an apparatus that easily removes dust flowing down a vertical drainage channel from the vertical drainage channel without using human power.

  The slope of a road with a cut or embankment structure is generally composed of small steps provided at each predetermined height and a slope with a constant slope sandwiched between the small steps. The drainage system that treats the wastewater is a small drainage channel that is provided in a small stage to collect precipitation on each slope, and a vertical drainage that is provided on the slope in order to drain the water in the small stage drainage channel into a gutter installed along the road. Each waterway is connected with a fence.

  The slope is often planted for greening, and it is also common in Japan that trees grow in adjacent mountain forests. For this reason, many dead leaves fall on the slope in the fall and flow into the waterways by wind and precipitation. In addition, empty cans thrown away by unsuspecting road users may also flow into waterways. These flow from the small drainage channel into the vertical drainage channel, and are finally processed in the gutters through the trough.

  When waste such as dead leaves or empty cans clogs the drainage that connects the vertical drainage channel to the side ditch or the small drainage channel, the drainage with a high flow velocity flowing down the vertical drainage channel overflows outside the channel and scours the slope around the channel. Can cause disasters. For this reason, a regular water channel cleaning work is necessary so that the garbage does not clog the soot, and much labor has been required.

  In order to remove the dust flowing through the water channel, a grid-like screen is attached to the water channel to supplement the dust. For example, Patent Document 1 discloses a method of removing the dust flowing into the water channel by attaching a basket to the water channel. However, all of these are problematic because it is necessary to remove the collected garbage manually.

Patent Publication 2003-64763

  The problem to be solved by the present invention is to provide a device that easily removes dust flowing down a vertical drainage channel from the vertical drainage channel without relying on human power.

  The present invention includes a screen portion for separating wastewater and waste attached in a vertical drainage channel, and a horizontal portion attached on the vertical drainage channel that automatically discharges dust accumulated in the screen portion to the outside of the vertical drainage channel when the wastewater pushes. Consists of.

  The screen part stands on the bottom of the channel from the surface of the inclined vertical drainage channel, has a length that allows a sufficient drainage gradient even after installation, and has many slits that separate wastewater and waste It is. With this structure, the waste is separated from the waste water and collected on the surface of the screen portion, and the waste water returns from the slit to the vertical drainage channel.

  In average precipitation, dust will collect on the screen, but if there is heavy precipitation, the water level in the vertical drainage channel will rise, and the dust collected on the screen will be pushed by the drainage and move toward the pre-empty part. It will be.

  Garbage that has been pushed from the screen part to the horizontal part due to repeated heavy precipitation changes its course in the horizontal direction of the water channel by the horizontal plate and is removed outside the vertical drainage channel.

  According to the present invention, it becomes possible to remove the waste in the vertical drainage channel outside the vertical drainage channel without relying on human power, to prevent the drainage system from being blocked and to prevent a disaster due to overflow of the drainage. .

It is the figure which showed the drainage system of the road slope. It is a top view of the dust removal apparatus of a vertical drainage channel. It is a side view of the dust removal apparatus of a vertical drainage channel. It is the top view which showed the condition in average precipitation. It is the side view which showed the condition in average precipitation. It is the top view which showed the situation in big precipitation. It is the side view which showed the situation in heavy precipitation.

  Embodiments of the present invention will be described below with reference to the drawings.

  Figure 1 shows the road slope drainage system. Precipitation falling on the slope 3 gathers in the small drainage channel 5, flows down the vertical drainage channel 6 through the eaves 7, and is processed into a gutter 8 along the road.

  FIG. 2 is a plan view of a vertical drainage debris removal device. Reference numeral 9 denotes a screen portion having a slit 10 which is set against the vertical drainage channel 6. Reference numeral 11 denotes a horizontal portion, to which a horizontal plate 12 extending outside the vertical drainage channel is attached.

  FIG. 3 shows a side view of the vertical drainage debris removal device. 13 is a horizontal line schematically showing that the screen portion has a sufficient drainage gradient.

  4 and 5 are a plan view and a side view showing the situation in a standard precipitation. Denoted at 14 is the level of drainage in the vertical drainage channel due to average precipitation, and the waste 15 separated from the drainage is pushed by the drainage and collected on the screen, and the drainage flows down from the slit 10 to the vertical drainage channel.

  6 and 7 are a plan view and a side view showing the situation under heavy precipitation. 16 is the level of the drainage in the vertical drainage channel due to heavy precipitation, and the waste 15 separated from the wastewater is pushed by the wastewater, and the waste collected in the screen is pushed out one after another toward the pre-filled part. Garbage is discharged out of the vertical drainage channel by the horizontal plate 12.
