図４で説明する。2. Description of the Related Art As a dam gate, as shown in FIG. 3, an opening 2a of a water channel 2 formed in a dam 1 is opened and closed by rotational displacement of a gate valve 4 having a skin plate 3. is there. At the periphery of the opening 2a,
An elastic seal member 5 that is slidably contacted with the skin plate 3 is provided to ensure water tightness when fully closed. The configuration of the sealing device 100 including the sealing material 5 will be described with reference to FIG.

下敷き板１３で保護されている。In FIG. 4, an elastic seal member 5 is made of a watertight rubber having a substantially convex cross section, and both shoulder portions 5a and 5b thereof are holding metal fittings 6 (6A and 6B) having shoulder fitting portions 6a and 6b and bolts. It is fixed to the dam 1 by 7 (7A, 7B). In the recessed portion 8 formed on the lower surface of the watertight rubber 5,
An elastic tube 11 into which pressure water W is supplied from a water pressure pump 9 (FIG. 3) through a pressure water supply pipe 10 is fitted in a built-in state, and this tube 11 is attached to a dam 1 by a bolt 12 (12A, 12B) and is protected by a rubber underlay plate 13 fixed thereto.

この部分のシールが達成される。In such a structure, when the pressure water W is supplied from the water pressure pump 9 through the pressure water supply pipe 10 into the elastic tube 11, the elastic tube 11 expands, so that the watertight rubber 5 is in a chain line state. Is expanded and deformed to the solid line. Therefore, the head portion 5c of the watertight rubber 5 comes into pressure contact with the skin plate 3 of the gate valve 4,
Sealing of this part is achieved.

When the skin plate 3 passes by, the head portion 5c of the watertight rubber 5 is pushed upward as shown in FIG. Watertight rubber 5 both shoulders 5
Although a and 5b are pressed by the taper of the shoulder fitting portions 6a and 6b of the pressing member 6, when the pressure of the pressure water W increases, the watertight rubber 5 may come out.

が図８のように引き摺り出されることもある。Further, when the gate valve 4 is moved downward, that is, in the closing direction, the pressure water W is drained to prevent the head 5c of the watertight rubber 5 from coming out, but the conditions such as temperature and water pressure change. When the gate valve 4 comes close to the watertight rubber 5 side due to the excessive pressure contact, if the gate valve 4 is lowered as it is, the head 5c of the watertight rubber 5 is rubbed by the skin plate 3 5c
May be pulled out as shown in FIG.

るおそれがある。On the other hand, until now, the designed water pressure of the watertight rubber 5 was at most 60 m head, but recently, it has been 14
A design water pressure as high as 0 m head has begun to be required for the watertight rubber 5, and unless the rigidity of the watertight rubber 5 is secured so as to satisfy this requirement, the watertight rubber 5 deforms abnormally due to water pressure and may cause water leakage, or a holding metal fitting. There is a risk of being hit by a shock and being damaged.

的とする。The present invention has been made in view of the above situation, and it is possible to prevent the watertight rubber from slipping out by the opening / closing operation of the gate valve, and there is a possibility that the watertight rubber may be abnormally deformed by high water pressure or the like to cause water leakage or damage. In other words, it is an object of the present invention to provide a gate sealing device capable of exhibiting a proper sealing property.

On the outer surface of the portion facing B, a metal steel plate, for example, a stainless steel plate 21 (2) is provided as a reinforcing plate having curved portions 21a near the base of the head 5c toward the shoulders 5a and 5b, respectively.
1A, 21B) are attached. A dowel 21b is attached to the inner surface of the stainless steel plate 21 so as to mechanically and firmly bond with the watertight rubber 5. 22
(22A, 22B) are notches formed at the inner lower edge of the holding metal fitting 6 corresponding to the curved portion 21a of the stainless steel plate 21. A wire steel wire 23 (23A, 23A) is formed along the longitudinal direction on both shoulders 5a, 5b of the watertight rubber 5.

If the pressure-tight water W is supplied to the inside of the water-container 1 and the water-tight rubber 5 is expanded and deformed, the head 5c of the water-tight rubber 5 is brought into close contact with the skin plate 3 of the valve gate 4 to obtain water-tightness.

れるおそれはない。Even when the watertight rubber 5 is expanded and deformed when the gate valve 4 is closed from the intermediate opening, the head portion 5c of the watertight rubber 5 is reinforced by the stainless steel plate 21, and the steel plate 21 is also reinforced. Since the bent portion 21a increases the rigidity of the gate valve 4 in the opening / closing direction, the skin plate 3 prevents the head portion 5c of the watertight rubber 5 from being largely deformed, so that the watertight rubber 5 is removed. Is effectively prevented. Further, even when the skin plate 3 is excessively pressed against the watertight rubber 5 due to a change in conditions such as temperature and water pressure, and the friction between the skin plate 3 and the watertight rubber 5 becomes strong, the watertight rubber 5 is pulled out. That's not it.

も防止される。Further, since the rigidity of the watertight rubber 5 is enhanced by the stainless steel plate 21, the watertight rubber 5 is not deformed abnormally even when the water pressure applied to the head 5c of the watertight rubber 5 is increased. Is suppressed and there is no risk of water leakage. In other words, it is possible to easily cope with a high design head in the water channel 2. Further, since the watertight rubber 5 is less likely to be deformed and hit the pressing fitting 6, the watertight rubber 5 is prevented from being damaged.

By embedding, the retaining of the watertight rubber 5 is further strengthened.

ができる。As described above, according to the present invention, on the outer surface of the portion of the elastic sealing member facing the pressing metal member on the head,
Since a reinforcing plate with a curved portion that bends toward the shoulder is provided near the base of the head, it is possible to prevent the elastic seal material from slipping out when the gate valve is opened and closed, and even when the water pressure is high. It is also possible to eliminate the possibility that the material is deformed abnormally to cause water leakage, or the pressing metal fitting is damaged.
