Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a diagonal gutter, and relates to a structure for preventing earth and sand from entering and accumulating in the door vertical guide section.

(Background of the idea) Diagonal culverts have the advantage of being able to be installed without excavating the slope, which saves construction costs, and there is no need to change the natural shape of the river.

However, diagonal gutters had the fatal drawback that dirt and sand could enter and accumulate in the guide section that guides the raising and lowering of the door body, making it impossible to raise and lower the gate body, so diagonal gutters were not generally adopted.
In reality, sluice gates were installed vertically.

(Summary of the invention) The present invention was made in view of the above circumstances, and the purpose of the invention is to prevent dirt from entering and accumulating in the guide part that guides the raising and lowering of the door body. To provide a diagonal gutter which can always be smoothly moved up and down.

To this end, the present invention has been developed by placing dirt removal plates on both sides of the upper surface of the door body and on the top of the upper plate of the guide part, ensuring a small gap that does not interfere with the raising and lowering of the door body. Both sides of the door body and both sides of the guide are designed to prevent dirt from entering the guide part unnecessarily as much as possible, and to quickly discharge the dirt that has slightly entered the guide part through the small gap. A large gap larger than the above-mentioned small gap is secured on the inner surface.

By configuring the diagonal gutter in this way, it is possible to prevent dirt from entering the guide part as much as possible, and also to allow the dirt that has slightly entered the guide part to slide down the large gap and exit the guide part from the opening at the lower end of the guide. It is designed to be discharged quickly by natural fall.

(Example) Hereinafter, an example of the present invention will be explained according to the drawings. Figure 1 is a cross-sectional view of a river, in which a diagonal gutter 1 according to the present invention is installed diagonally on an inclined slope. In addition, a water pipe 2 is buried in the embankment.

2 and 3 are a front view and a side sectional view of the diagonal gutter 1, and 3 is a door body, and the lower surface of both sides of the door body 3 is slid 5a by the operation of the hoisting machine 4. , 5b to slide up and down inside the door groove 6.

Further, a swash plate 7 for soil removal is attached to the upper part of the door body 3, and this swash plate 7 is connected to a pin rack 8.

This swash plate 7 is for scraping off earth and sand that accumulates in the door groove 6 when the door body 3 rises.

Guide parts 9aw9b are provided on both sides of the lower part of the door groove 6 to guide the raising and lowering of the door body 3.
A stopper 10 that defines the lowering limit of the door body 3 is protruded from the lower end openings 14a and 14b of the doors 9a and 9b.

On the upper inner surfaces of the upper plates 91a and 91b (see Fig. 4) of the guide parts 9a and 9b, there are plates 11 and 11 for removing dirt, which extend toward both sides of the upper surface of the door body 3 and are installed vertically to remove the dirt. A small gap t1 is ensured between the plate 11.11 and the upper surface of the door body 3.

The guide parts 9a, 9b have a U-shaped cross section, and on both sides of the upper surface of the door body 3, there are plates 12, 12 for removing dirt that extend toward the upper plates 91a, 91b of the guide parts 9a, 9b. The earth and sand remover is erected along the direction, and a small gap t2 is also secured between the plates 12, 12 and the upper plates 91a, 91b of the guide parts 9a, 9b.

The above-mentioned small gaps tl and t2 are secured so that the sliding friction when the door body 3 is raised and lowered is reduced, and the door body 3 can be smoothly raised and lowered.

In addition, there are rubber stoppers 13.13 on both sides of the bottom surface of the door body 3.
is provided.

Moreover, a large gap t3 larger than the above-mentioned small gaps tl and t2 is secured between both side surfaces of the door body 3 and the inner surfaces of the guide parts 9a and 9b.

Since the main diagonal gutter 1 has a structure as described above, the guide portion 9
Sediment intrusion into a and 9b is removed by plates 11, 11,
12, 12, the guide portions 9a, 9b
Almost no dirt enters inside.

However, it is unavoidable that a small amount of earth and sand will enter the guide parts 9a and 9b from the small gaps tLt2, which are provided to allow the door body 3 to move up and down smoothly. If they accumulate inside 9a and 9b, the movement of the door body 3 up and down will be hindered.

However, since this diagonal gutter 1 has a large gap t3 between the door body 3 and the guide part 9at9b, the dirt that has slightly entered into the guide part 9a * 9b will be removed as shown by arrow A in Figure 2. The lower end opening 14a slides down inside the large gap t3.

14b to the outside of the guide portions 9a, 9b by rapid natural fall.

(Effect of the invention) As explained above, in the diagonal gutter 1 according to the invention, the plates 11, 11, 12, 12 prevent the invasion of earth and sand into the guide parts 9a and 9b, and the small gap tl The structure is such that even the dirt that has entered slowly from t2 is quickly discharged by natural fall from the lower end openings 14a and 14b through the large gap t3, and the dirt accumulates in the guide parts 9a and 9b. This has the effect that the door body 3 can be raised and lowered smoothly at all times.
