Abstract

PURPOSE:To enhance the natural purifying ability of streaming water by furnishing a turbulent flow generating part having a surface with projections and recessed at the inside of a U-shaped side gutter formed from the bottom wall and the two side walls. CONSTITUTION:A turbulent flow generating groove 4 is furnished at the side wall 3 of a U-shaped groove constituting a side gutter 1 for watercourse. The streaming water is allowed to run against this groove 4, and change is generated in the stream to enhance the agitation effect, and thereby oxygen absorption of the streaming water is improved. The side wall 3 shall consists of a plane, and bosses for generating turbulence are provided at the bottom to exert the same effect. Thereby the natural purifying ability of streaming water is enhanced.

Description

[Detailed Description of the Invention] Purpose of the Invention [Industrial Field of Application] This invention relates to a waterway gutter installed on both sides of a road during construction, and a waterway covered with concrete from the bottom to both sides during construction. .

[Prior art and problems to be solved by the invention] Currently,
Wastewater mixed with goyo flows into these gutters.

The applicant believed that if this wastewater could be purified even a little, it would be useful for beautifying the city. This also applies to waterways similar to side ditches.

Therefore, the present invention is devised to improve the self-cleaning ability of running water.

Composition of the invention [:! Means for Solving Problem R] In view of such an object, the present invention provides a waterway gutter 1 consisting of a bottom wall 2 and side walls 3 rising from both sides of the bottom wall 2, or , in the waterway 16 whose bottom and both continuous sides are covered with concrete,
The inner surface thereof is provided with uneven turbulence generating portions 4, 5, 11, and 14.

[Function] When running water hits this turbulence generating part 4, 5, 11, 14,
A change in flow occurs, which increases the agitation rate and improves oxygen absorption.

[First Embodiment] First, a first embodiment of the present invention will be described with reference to FIGS. 1 and 2.

A concrete gutter 1 consists of a bottom wall 2 and side walls 3 rising vertically from both sides of the bottom wall 2. A turbulent flow groove 4 is formed on the inner surface of both side walls 3 so as to extend in the vertical direction from the inner surface of the bottom wall 2 to the upper end of the side wall 3. Each of these turbulence generating grooves 4
are arranged in a staggered manner when viewed from above. Note that the inner surfaces of both side walls 3 and the inner surface of the bottom wall 2, excluding the turbulence generating groove 4, are each formed into a planar shape.

The required number of such side gutters 1 are installed side by side on both sides of the road during construction.

When drainage water flows in the direction of the arrow in the installed side gutter 1, the drainage water hits the turbulence generation grooves 4 on both side walls 3, causing a change in the flow. This change in flow increases the agitation rate of the wastewater, improves oxygen absorption into the wastewater, and naturally purifies the wastewater.

[Second Embodiment] Next, a second embodiment of the present invention will be described with reference to FIGS. 3 to 6.

A concrete gutter 1 consists of a bottom wall 2 and side walls 3 rising vertically from both sides of the bottom wall 2. The inner surface of the bottom wall 2 and the inner surface of the side wall 3 are each formed into a planar shape.

A turbulence generator 5 is removably fitted between the inner surfaces of both side walls 3 and placed on the inner surface of the bottom wall 2.

This turbulence generator 5 is formed into a U-shaped cross section by an upper wall portion 6 and both side wall portions 7, and when fitted into the side groove 1, the outer surface of the side wall portion 7 is aligned with the inner surface of the side wall 3.
The lower end of the side wall portion 7 rests on the inner surface of the bottom wall 2. A passage 9 is formed between the earth wall part 6 and the inner surface of the bottom wall 2. The outer surface of the earthen wall portion 6 has a planar shape parallel to the inner surface of the bottom wall 2.

The required number of side gutters 1 into which such turbulent flow generators 5 are fitted are installed in line on both sides of the road during construction.

Drainage water flowing in the direction of the arrow in the side gutter 1 flows in the passage 9 or on the earth wall part 6 depending on its depth. Then, as the flow passes through this turbulence generator 5, a change is given to the flow. This change in flow increases the agitation rate of the wastewater, improves oxygen absorption into the wastewater, and naturally purifies the wastewater.

[Third Embodiment] Next, a third embodiment of the present invention will be described with reference to FIGS. 7 to 10.

A concrete gutter 1 consists of a bottom wall 2 and side walls 3 rising vertically from both sides of the bottom wall 2. Two turbulence generators 11 are provided protruding inside one side gutter 1 at the corners between the bottom wall 2 and the side wall 3. A passage 12 is formed between the two turbulence generators 11 on the inner surface of the bottom wall 2. The other side? 1! One turbulence generator 11 is located inside the bottom wall 2.
It is provided protrudingly on the inner surface of. When the grooves 1 on both sides are lined up, the passage 12 between the turbulence generating bodies 11 in one side groove 1 is on the extension line of the turbulence generating bodies 11 in the other side groove 1.

Further, both turbulence generators 11 of one side wall 1 are located on an extension of a passage 13 formed on the bottom wall 2 between the turbulence generator 11 of the other side gutter 1 and both side walls 3.

Such side gutters 1 are installed side by side on both sides of the road during construction. Note that the side gutters 1 on one side and the side Ill on the other side are arranged alternately.

When drainage water flows in the direction of the arrow in the side gutter 1, the drainage water hits each turbulent flow generator 11, causing a change in the flow. This change in flow increases the agitation rate of the wastewater, improves oxygen absorption into the wastewater, and naturally purifies the wastewater.

[Fourth Embodiment] Next, a fourth embodiment of the present invention will be described with reference to FIGS. 11 to 13.

A concrete gutter 1 consists of a bottom wall 2 and side walls 3 rising vertically from both sides of the bottom wall 2. A pair of turbulence generating grooves 4 are formed on the inner surfaces of the side walls 3 so as to face each other and extend from the inner surface of the bottom wall 2 to the upper end of the side wall 3 in the vertical direction. A turbulence generator 14 is removably fitted into both turbulence generation grooves 4 from above the side groove 1 between the side walls 3 and placed on the bottom wall 2. A passage 15 is formed between this turbulent flow generator 14 and the inner surface of the bottom wall 2.

Each side gutter 1 is installed side by side on both sides of the road during construction.

The drainage water flowing in the direction of the arrow in the side gutter 1 first passes through the turbulence generator 14.
and then flows over this turbulent body 14 or through a passage 15 . This causes a change in the flow. This change in flow increases the agitation rate of the wastewater, improves oxygen absorption into the wastewater, and naturally purifies the wastewater.

[Fifth Embodiment] The first embodiment to the fourth actual flow example embody the present invention in a side gutter, but as shown in FIG. The same active flow generating body 5 as in the second embodiment may be provided in various water channels 16 whose both sides are covered with concrete. The same applies to the turbulence generating grooves 4 and turbulence generating bodies 11 and 14 in other embodiments.

Effects of the Invention According to the present invention, the turbulent flow generating portions 4 and 5 are provided on the inner surface of the waterway gutter 1 and various waterways 16 covered with concrete.
, 11.14, the flow changes, oxygen absorption improves, and the natural purification ability of running water improves.
