Description

[Detailed description of the invention] <Industrial application field> This invention eliminates the need for the installation of gate pillars and management bridges for opening and closing the water shutoff doors provided on the gutter pipes. The present invention relates to a gutter-pipe gate which eliminates the danger associated with the operation in (1) and reduces the construction cost.

<Conventional technology and its problems> In a dike constructed in a river, a gutter pipe is buried so as to cross the dike. This gutter pipe is required for so-called drainage and water intake for guiding water outside the embankment (inside the river) to the inside of the embankment or for guiding water from the inside of the embankment to the outside of the embankment. If water is not to be taken, the gutter must be closed. In order to achieve this object, a conventional method generally employed is to arrange a door b which moves up and down at an opening outside the embankment (inside a river) of the gutter pipe a as shown in FIG. At the same time, it was necessary to install a gate post c for moving the door b up and down, and to bridge a walkable management bridge d over the gate post c from the top of the embankment. As described above, the cost required for installing the gate post c and the management bridge d is not only enormous per se, but also quite high, even though the danger prevention fence is arranged above the management bridge d and the gate post c. Since the work is performed at a location, the danger cannot be said to have been completely eliminated, and it is possible for anyone other than those involved (for example, children) to invade. I couldn't say.

<Means for Solving the Problems> In order to solve the above-mentioned problems, the gutter pipe gate according to the present invention provides the gutter pipe near one opening of a gutter pipe buried across a river embankment. A guide member formed in a substantially L-shape that reaches the bottom surface of the gutter pipe while being substantially parallel to the upper surface of the pipe is provided, and a movable door body is formed directly or indirectly on this guide member, and A gate is connected to a rear end portion of the door body to move the door body along the guide member, thereby opening and closing the gutter pipe, and a gate post and a management bridge for opening and closing the door body which have been conventionally required. This eliminates the need for installation of such equipment, eliminates the dangers associated with work on gate posts and management bridges, and reduces construction costs.

<Embodiment> Next, an embodiment of a gutter pipe gate according to the present invention will be described with reference to the drawings. 1 is a gutter pipe buried across the river embankment 2, and 3 is a gutter pipe 1 of this gutter pipe 1. A guide rail (guide member) formed so as to reach the bottom surface of the gutter tube 1 while being substantially parallel to the upper surface. Therefore, the guide rail 3 is formed in a substantially L-shape.
The guide rail 3 is disposed near one of the openings of the gutter tube 1.

Reference numeral 4 denotes a door formed in a square shape, and 5 denotes wheels arranged on both side edges of the door 4. When the wheels 5 are engaged with the guide rails 3, the door body 4 travels along the guide rails 3.
Alternatively, both sides of the door 4 may be directly engaged with the guide rail 3 without disposing the wheels 5 on the door 4. In any case, the door body 4 is indirectly engaged with the guide rail 3 via the wheels 5 and both side edges of the door body 4 are directly engaged with the guide rails 3.

Reference numeral 6 denotes a cylinder connected to the rear end of the door body 4 via a piston rod 7, and the cylinder 6 is fixed.

<Operation> When the cylinder 6 is actuated, the door body 4 is pressed or pulled by the rear end connected to the piston rod 7 by the piston rod 7, and the door body 4 moves along the guide rail 3. It moves back and forth and opens and closes the gutter tube 1.

In addition, if comprised as mentioned above, the door body 4 and the cylinder 6 etc. will exist in the river embankment 2, and the processing in the case where the maintenance of the door body 4 and / or the cylinder 6 etc. becomes necessary etc. arises. In order to solve the problem, a window 8 as shown in FIG. 1 is formed in the river embankment 2 at the upper portion where the door 4 and the cylinder 6 are located, and the window 8 is formed. It is preferable that a cover 9 is provided on 8.

<Effect of Invention> As described above, according to the gutter pipe gate according to the invention,
In the vicinity of one opening of the gutter tube buried so as to cross the river embankment, a substantially L-shaped guide member reaching the bottom surface of the gutter tube while being substantially parallel to the upper surface of the gutter tube is arranged,
A movable door body is formed directly or indirectly on this guide member, and a cylinder is connected to the rear end of the door body. Therefore, the gutter is moved by moving the door body along the guide member. Eliminate the danger of work on gateposts and management bridges by opening and closing pipes and eliminating the need for installation of gateposts and management bridges for opening and closing doors, which was conventionally required, and reduce construction costs. It has the effect of being able to do.
