Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block assembly type water channel for sewage, sewage, etc. formed by splicing water channel blocks, and more particularly to a splicing structure having steps between blocks.

[0002]

2. Description of the Related Art Conventionally, for example, as a water channel provided on a shoulder of a road, a block assembly type water channel is often used which is constructed by joining a plurality of water channel blocks having a flow channel space inside. In that case, in order to provide a gradient for water to flow in the flow passage formed inside, water channel blocks having different bottom surfaces of the flow channel space are spliced together.

In such a case, conventionally, a step portion between bottom surfaces of different heights is left as it is, or after joining, mortar or the like is buried in the step portion to eliminate the step and form a gentle slope. Is being done.

[0004]

However, in the block assembly type water channel according to the prior art described above, particularly when the step is left as it is like the former case, the water flow is disturbed at this step portion and dust is collected there. It is not preferable as a waterway because it may accumulate and sediment will accumulate. In the latter case, especially when the waterway is narrow or installed in a low place, the waterway is not so large that people cannot often enter it after assembly. There was a problem that the work to eliminate the step may not be practical.

Therefore, in view of the above-mentioned problems in the prior art, an object of the present invention is to provide a block assembly type water channel which is formed by joining a plurality of water channel blocks having different heights of the bottom surface of the channel. At the same time, it is an object of the present invention to provide a block assembly type water channel capable of easily and surely eliminating a step generated at a joint portion and forming a smooth water channel inside.

[0006]

In order to achieve the above-mentioned object, it is proposed by the present invention to form at least two or more water channel blocks in which a flow channel space for forming a water channel is formed. A block assembly type water channel for connecting a first water channel block and a second water channel block in which the bottom surface of the flow channel space is located at a position higher than the bottom surface of the flow channel space of the first water channel block. In the block assembly type water channel formed by, the upper surface having a slope connecting the flow channel space bottom surface of the first water channel block and the flow channel space bottom surface of the second water channel block, and the first water channel block A slope block having a bottom surface corresponding to the cross-sectional shape of the flow channel space and a tongue protruding downward from the end is fitted into the bottom of the flow channel space end of the first water channel block. , In, the tongue is a block prefabricated waterway, characterized in that fixed sandwiched between the first abutted with each other and the end face of the second water channel block.

[0007]

That is, according to the block assembling type water channel of the present invention, when forming the water channel by joining the first water channel block and the second water channel block to each other, the slope block as described above is used. By fitting in the bottom of the flow path space end portion of one water channel block, the upper surface of the slope block, the flow path space bottom surface of the first water channel block,
The step is eliminated by forming a slope which is higher than this and which communicates with the bottom surface of the flow path space of the second water channel block. In addition, since this slope block has a bottom surface corresponding to the cross-sectional shape of the flow passage space of the first water channel block, when assembling the water channel block, the slope block should be connected to the flow channel of the first water channel block. It is only necessary to fit it into the bottom of the end of the channel space, and tongues protruding downward from that end are abutted and fixed between the end faces of the first and second water channel blocks. Therefore, it can be easily and surely fixed at a predetermined position. That is, it is possible to form a smooth water channel inside the block assembly type water channel by simultaneously forming a gradient in the step portion of the water channel block while joining the water channel blocks having a step on the bottom surface.
