号）。2. Description of the Related Art Damping is used for repairing, painting,
When performing maintenance, inspection, and work such as replacing watertight rubber,
It is used as a temporary gate to shut off water on the storage side.
Usually, it is a rectangular oblong block that can withstand water pressure. Actually, the droppings are piled up in water to construct a temporary gate, and then the water between the temporary gate and the main gate is drained to perform the maintenance and inspection work. In the case of wood or concrete dropping, wood chips were sometimes filled with water to stop water, but in recent years high precision steel dropping has begun to be used, and packing must be used to stop water. Has become indispensable. Conventionally, as this watertight packing, there is known a watertight rubber packing having a rectangular cross section laid on all or a part of the periphery of an upper surface or a lower surface of a rectangular corner drop. In laying the waterproof packing, it is also widely practiced to form a step edge or to provide a fitting groove (Japanese Utility Model Laid-Open No. 58-59832, Japanese Utility Model Laid-Open No. 60-91619).
issue). There are also various known mechanisms that attach separate door stops to both ends of the corner drop and attach watertight rubber to the door stop to maintain the watertightness between the corner drop and the dam guide groove. No. 63-86134, Shokai 63-2332
No. 6). On the other hand, the watertightness of the dropper is not enough with packing alone, and it is important to stack many droppers in the correct position, but in order to facilitate this loading work, the side or top of the dropper is required. Hooks have also been used (see 63-86134).

った。However, when the packing is formed on the peripheral portion of the upper surface or the lower surface of the corner dropping member,
When dropping is piled up in water, for example, the water in the area surrounded by the packing on the top surface loses a place to escape, and is compressed by the top dropping and becomes high pressure, destroying the packing or removing the top and bottom corners. Adsorption becomes poor, the upper corner drop slips and is not loaded at the correct position, and as a result, watertightness deteriorates. Conversely, if the stacking is performed at the correct position and the packing functions, the portion surrounded by the packing becomes negative pressure, and it is difficult to separate the packing at the time of disassembly. On the other hand, the door stop is provided with a considerably large gap between the door stop and the inner wall of the guide groove for facilitating taking in and out of the corner drop.
Therefore, simply providing a watertight packing at the door stop as in the past, as long as there is water remaining between the main gate and the temporary gate due to the corner drop, the water pressure from the storage side is not applied to the corner drop, Swinging or tilting, there is a gap between the packing and the dam guide groove,
Not only could not obtain sufficient watertightness, but also the danger was high.

る。In this case, in order to increase the pressure resistance of the corner drop, it is desirable to form the water weir portion thicker than the contact portion of both doors. An elastic body such as neoprene rubber is used for packing.However, when the fitting groove is provided and fitted in the fitting groove rather than being laid directly on the upper surface or lower surface of the water dam, the watertightness may be deteriorated due to deformation. And it is not easily deteriorated with time and is stable for a long time. A fitting groove extension is provided from the peripheral fitting groove to the gate side wall surface, and the packing extension is fitted to prevent leakage of water coming around the side end. It is better for the packing to have a substantially circular cross section than a square cross section. In order to facilitate the work of loading a corner drop with a crane or the like, it is preferable to embed a hanging tool on the upper surface of the water weir so as not to protrude from the surface. Further, if a grip is provided at an arbitrary position on the side wall surface of the gate of the water weir so as to form a trap when loaded, inspection and maintenance work after temporary installation is easy. Further, in order to maintain the watertightness of the door stop, a plate-like packing may be attached to the gate side wall surface of each door stop so as to extend from the side end. The packing extending portion is provided so as to be in contact with the plate-like packing to further ensure watertightness.
