Abstract

PURPOSE:To raise the safeness of rising and falling actions by a method in which a wire rope-housing groove opened from upstream to downstream side along at least one side wall of waterway, a gate is pivotally supported on the waterway bed, and the upstream path of the side wall is made into a circular arc form. CONSTITUTION:The lower end of a rising and falling gate 4 is pivotally supported on the bed 1' of a waterway 1, and a falling dam is formed between both-side walls 2. A gate-side slide plate 9 which is produced in factory in advance is erected on the extended face of the side 2' and concrete is placed from the upper end opening of a downward sloped plate 10' to form a wire rope-housing groove 3. The wire rope-fitting tool 5 of the gate 4 is set on the outside of the plate 9 and connected to a wire rope 7 set in the groove 3, and the upper edge 8 of the plate 9 is made into a circular arc form along the rising and falling arc line of the fitting tool 5 and the groove 3 is opened toward the downstream side. The falling-down of the gate 4 can thus be safely made by housing the rope 7 in the groove 3.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a wire-type lodging weir for a waterway and a method for constructing the same.

``Prior art'' In order to prevent debris flowing down a waterway from adhering to the wire for operating the wire weir, the wire and wire attachment shaft or rope wheel are stored in side wall storage chamber C. It has been developed (Special Publication No. 2-4723). However, the side wall penetration part is formed with an arc-shaped opening that allows rotation of the penetration shaft, and is equipped with a dust inflow prevention cover consisting of an arc-shaped long plate that moves with the door body to open and close the arc-shaped opening. It is provided. However, such a device has a complicated structure, and when the door is raised, the arc-shaped inflow prevention cover is exposed in the air, and the arc-shaped opening remains open, so if foreign matter enters the lobe car storage member through the opening, Since it is not discharged, there is a concern that the door body will not be completely collapsed in the event of a flood, which may lead to a lack of safety, and the storage member is arc-shaped and precisely aligned on the circumference around the pivot axis of the door body. It took skill to build.

"Problems to be Solved by the Invention" The present invention provides a wire-type lodging weir that has a simple structure, does not require precision, has high safety in raising and lowering operations without the risk of debris being caught in the wire lobe, and is easy to construct. The purpose is to

"Means for Solving the Problems" In order to achieve the above object, the present invention forms a wire rope accommodation groove along at least one side wall of the waterway that opens from above the side wall to the downstream side, and the inner side of the side wall. A gate body is pivotally supported on the waterway floor, a wire rope fixture provided on the upper edge of the gate body is placed outside the side wall, and the fixture and a hoisting machine provided on the side wall are connected. The upper edge of the side wall is formed in an arc shape along the undulating arc line of the upper edge of the door body, and the groove is opened to the downstream side. The wire type (f1) lowered weir according to the invention, which is formed by the side wall or the sliding plate on the side of the door body, wherein the bottom surface of the wire rope storage groove is a downwardly inclined surface facing the downstream side. A notched concave surface is formed on the side surface of the wire type lodging weir waterway according to the second invention, and a wire rope accommodation groove is formed between the concave surface and a door body side sliding plate disposed on an extension surface of the side surface, The wire according to the second or third invention, characterized in that a downwardly inclined plate is arranged inside the groove, and concrete is poured between the concave surface and the sliding plate at the lower part of the inclined plate. It is constructed using the type lodging weir construction method.

``Function'' Therefore, the door body 4 is raised as shown in FIG. 1 to maintain the water level 12 on the upstream side, and the garbage is flushed downstream beyond the door body 4. However, the wire rope 7 that pulls the door body 4 rearward in an upright state is inside the storage groove 3, and the overflow prevention plate 8' of the door side sliding plate 9 prevents debris from falling onto the wire rope 7. There is no risk of getting caught. When the hoisting machine 6 is operated to unwind the wire rope 7, the door body 4 falls down downstream centering on the pivot part, but at this time, even if garbage enters the storage groove 3 together with overflow water. The garbage flows out downstream of the folding door body 4 from the downstream opening of the groove 3. The bottom surface of this accommodation groove 3 is the waterway bed 1
Since the downwardly inclined surface 1o faces 1o, the garbage flowing down within the space 3 is pushed away by the flowing water and is quickly discharged.

The door body side sliding plate 9 is manufactured in advance at a factory, and is erected on the extended surface of the side surface 2', and concrete is poured from the upper end opening of the downwardly inclined plate 10' to form a wire rope storage groove. 3 is formed.

"Embodiment" A stage 13 with a lower downstream side is formed in the water channel 1, and the lower end of the door body 4 which can be raised and lowered is pivotally supported by a plurality of bearings on the downstream water channel floor 1' of the stage 13, and both side walls 2.2 A lodging weir is formed in between.

A wire rope accommodation groove 3 is formed along at least one side wall 2 and opens downstream I1) from above the side wall 2. The housing groove 3 is provided downstream from the step 13, and the side wall 2 is formed by a metal door side sliding contact plate 9 having an inner surface on an extension of the upstream side surface 2' of the step 13. The housing groove 3 is formed by forming a cut concave surface 1) on the side surface 2' of the water channel 1, and forming between the concave surface 1) and the sliding contact plate 9 on the extended surface of the side surface 2'. The upstream side of the plate 9 is connected to the upstream side 2' and to the water bottle. A wire rope fixture 5 provided on the upper edge of the door body 4 is placed on the outside of the sliding contact plate 9 (on the housing groove 3 side), and a wire rope fixture 5 provided on the upper surface of the side wall 2 is connected to the wire rope fixture 5 on the upper surface of the side wall 2. The winding drum 6' is connected to the winding drum 6' by a wire rope 7 disposed within the housing groove 3. The upper edge 8 of the sliding contact plate 9 is formed into an arc shape along the undulating arc line of the fixture 5, and the groove 3 is opened to the downstream side.

The bottom surface of the receiving groove 3 is formed by a downwardly inclined surface 10 facing downstream, and the lower end of the inclined surface 10 is brought into contact with the channel bed 1'. This inclined surface 10 connects the lower end of the downwardly inclined plate 10' interposed between the concave surface 1) and the sliding contact plate 9 to the waterway bed.
It is formed by placing concrete between the concave surface 1) and the sliding contact plate 9 at the lower part of the inclined plate 10'. 8' in the figure is a rectangular portion connected to the upper end of the arcuate upper edge 8 of the sliding contact plate 9, which serves as a stopper for the mounting bracket 5 and an overflow prevention plate 14 when the door body is erected.
．． 15 is an anchor for the sliding contact plate 9, 16 is a watertight device provided on both sides of the door body 4, and 12' is an overflow water level.

"Effects of the Invention" Since the present invention is configured as described above, the wire rope 7 for operating the folding door body 4 is housed in the groove 3, so there is no risk of garbage getting caught in the groove 3. The overflow water from the door body 4 will discharge the garbage that has entered into the groove 3 downstream, and there is no risk of it accumulating in the groove 3, and the downward slope 10 will increase the flow rate and the accumulated garbage in the groove 3 will be discharged. Ru. Therefore, not only can the door body 4 be folded down safely, but also the structure and construction can be simplified.
