行なわれていた。BACKGROUND ART In recent years, there has been an urgent need to remodel water gates such as crest gates in dams due to their aging and several revisions to standards. Conventionally, when modifying this crest game, it was difficult to lower the water level of the reservoir due to economic reasons due to the power generation stoppage. Therefore, when modifying the crest gate, a corner drop was inserted in the front of the gate body and the water level was lowered. Renovation work was being carried out in the state.

支保工４を設けたりしていた。 By the way, as shown in Figure 3, the door groove 1 for corner dropping is very close to the crest gate door stop 2, and when the concrete part is scraped to replace the door stop hardware, the water pressure acting on the corner dropping is may not be able to tolerate it. Therefore, in the past, the water level had to be lowered or a shoring 4 was installed behind the corner drop 3 as shown in Fig. 4.

から構成されている。Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Reference numeral 11 is a corner drop placed on the upstream side of the water gate of the waterway 12 to temporarily stop the water, and both ends can be inserted into and removed from the door grooves 14 formed on the side wall of the pier 13 forming the waterway 12. The spar-shaped corner cutter body 15 is removably fixed at both ends of the upstream side surface of the water channel 12 of the corner cutter body 15 via attachment members 16, and the other end is attached to the pier 13. It is bent so that it is in the front position of the upstream end face of
A bearing plate 17 that abuts the upstream end surface of the pier 13 at the other end is constituted by a pair of arm bodies 19, each of which is provided via a position adjustment jack 18. The corner drop main body 15 includes a pair of upper and lower main girders 20, 20', an auxiliary girder 21 that connects these main girders 20, 20' at a plurality of points, and the main girder 2.
It is comprised of a skin plate 22 stretched over the downstream side surfaces of 0 and 20', and watertight rubber 23 attached to the downstream side surfaces of both ends of the skin plate 23 to provide watertight sealing between the skin plate 22 and the door groove 14.
