Abstract

<P>PROBLEM TO BE SOLVED: To provide a convenient and safe free gradient side ditch used for irrigation and draining in common, for arranging a flash board for inserting a draining sheathing board into the free gradient side ditch, due to being very dangerous work by becoming a hindrance to traffic for damming up, taking and draining flowing water by a sandbag by rolling up a cover plate of the continuous free gradient side ditch. <P>SOLUTION: A semi-elliptic cutout part 2 is arranged in the free gradient side ditch 1 as a water flash board, and the sheathing board 3 attached with a grip 4 is inserted along a flash board groove 6, and the flowing water is taken in by a damming-up drain port 5. Or a dummy sheathing board 11 attached with a grip 12 is inserted into the flash board groove 6 in the semi-elliptic cutout part 2 as the water flash board unused due to a water bidirectional coping type. In draining, a drain flow rate is adjusted by the height of the water drain port 5, by inserting the draining sheathing board 8 along a groove 9 from the draining flash board 7 arranged in a cover opening part 10 of the free gradient side ditch 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

The present invention relates to a drainage-use free-gradient side groove for making a corner drop in a free-gradient side groove and taking water with a drop lid and adjusting a drainage flow rate.

Conventionally, the cover plate of the free-gradient gutter was rolled up, the water was dammed up with sandbags, etc., water was taken, and the drainage was used by making holes in the concrete.

The problem to be solved was dangerous because the width of the roadway could not be secured because the cover plate was turned over while taking water. Moreover, since the ceiling part of the free-gradient side groove was slightly narrower than the bottom part, it could not be lifted by putting the board into it. At the time of drainage, a hole was dug in the concrete itself, adjusted in size, and closed with a wooden board. The present invention has been made to compensate for the above-described drawbacks.

Means to solve the problem

In the present invention, the free-gradient side groove (1) is provided with a water-dropping semi-elliptical cutout (2), and the sheet plate (3) with a handle (4) is inserted along the corner-dropping groove (6). Water is taken from the drainage port (5) for damming. Because it is compatible with water irrigation in both directions, a dummy seal plate (11) with a handle (12) is inserted into the corner dropping groove (6) in the unused water corner dropping semi-elliptical cutout (2). When draining, drain drainage plates (8) are inserted along the groove (9) from the draining corner drop (7) provided in the lid opening (10) of the free-gradient side groove (1). Adjust the drainage flow rate according to the height of (5). The present invention is a drainage-use free-gradient side groove having the above-described configuration.

The invention's effect

  Since the water intake method according to the present invention is simple in the water intake operation of inserting the baffle into the free-gradient side groove, it can be handled by any person and can be used in any direction of flowing water. When the board is inserted, the handle part of the board is the same height as the top edge of the free-gradient gutter, so it is safe and convenient during the water intake without interfering with traffic. When draining, the drainage flow rate can be adjusted by the height of the plate.

  The free-gradient side groove (1) is provided with two water-dropping semi-elliptical notches (2) and two corner-dropping grooves (6). Also, a drainage corner drop (7) is provided in the lid opening (10), a corner drop groove (9) is provided, and a drainage outlet (5) is provided on the side surface. The present invention has the structure as described above, and when this is used, a squeeze plate is inserted into one of the water corners, and a dummy squeeze is inserted into the other water corner drop to take water. Also, when draining, put drainage board into drainage corner dropper by adjusting drainage, adjust and use.

  FIG. 3 shows the drainage combined type free gradient side groove of the present invention.

  It is a top view of the present invention.   It is CC sectional drawing in FIG. 1 of this invention.   It is a perspective view of the present invention.   It is BB sectional drawing in FIG. 1 of this invention.   It is AA sectional drawing in FIG. 1 of this invention.   It is the enlarged view which put the water supply board in the water angle drop of this invention.   It is the enlarged view which put the dummy board in the water angle drop of this invention.
