2371号公報参照）。(Prior Art and its Problems) A conventional overpressure prevention device of this type will be described in use in an undulating weir made of an air-inflatable flexible membrane. In addition, for flexible membrane undulating weirs, a flexible membrane (e.g., rubber-coated cloth) envelope (bag-like body) forming the weir body is attached to at least the river bed in the direction across the river, and communicates with the inside of the envelope. A fluid, such as air or water, as an expansion medium is sent through an inlet/exhaust (water) pipe to cause the enclosure to expand and stand up, and the fluid is discharged from the inside of the envelope to cause the enclosure to contract and fall down (for example, Japanese Patent Publication No. 11702/1973).

る。 As shown in Fig. 1, in the conventional method, a weir overpressure prevention pipe 2 is placed in one water seal pipe 3, and the pressure exceeding the height of the pipe in the water is undulated by a water-inflatable flexible membrane. When added to the envelope 1 forming the weir body of the weir, the water seal pipe 3
Air 11 is blown out from the tip of the overpressure prevention pipe 2 at the bottom to prevent overpressure from being applied to the weir.

となれば大変な労力となる。 The above device consists of only one water-sealing tube, and is constructed of a high internal pressure weir (considering the future enlargement of weirs).
(Weir internal pressures of 5 mAq to 10 mAg occur frequently), the height of the water seal pipe becomes high, and the operation room must be dug deep as shown in Figure 2, or the operation room building 12
It is necessary to increase the height of the structure, which is uneconomical.
In addition, manually filling the water seal tube with water at a height of 5 to 10 meters becomes a huge effort.

That is, the overpressure prevention device of the present invention uses a plurality of water seal tubes, and the water seal tubes are connected by a communicating pipe extending from the top cover of the previous water seal tube to the bottom of the next adjacent water seal tube, and the first water seal tube connected In the sealing tube, the pipe coming out of the pressure vessel is led to the bottom of the water sealing tube, and the final water sealing tube does not require a top cover.When the pressure in the pressure vessel becomes abnormally high, the gas inside the vessel is connected and all the water is removed. It is characterized by being discharged into the atmosphere through a sealed tube.

部位を示し、その他１０は給水パイプ、１４は水
封管への給水パイプを示している。 The basic mechanism of the overpressure prevention device for a gas pressure vessel of the present invention is a water seal tube for overpressure prevention using an undulating weir made of an air-inflatable flexible membrane. That is, the device of the present invention is one in which a plurality of water seal tubes 3', 3'', etc. are connected by a water seal tube communication pipe 9, as shown in FIG. Other water seal pipes other than this one require a top cover.In Figure 3, the same symbols as in Figures 1 and 2 indicate the same parts, 10 is a water supply pipe, and 14 is a water seal. Shows the water supply pipe to the pipe.
この装置の作動は給気時の送風機７の止めわす
れ等により起るもので以下のとおりである。 The operation of this device occurs due to failure of the blower 7 to stop during air supply, and is as follows.

外は閉じられているものである。(1) The internal pressure of the envelope 1 that forms the weir increases, and approx.
When the pressure exceeds H 2 mAq, air is discharged from the tip of the overpressure prevention pipe 2 to the first water seal tube 3', increasing the pressure in the water seal communication pipe 9. Note that the water supply valve 10 is closed except when water is supplied to the water seal tube 3.

(In Figure 3, this is the final water seal tube.) Air is exhausted from the bottom. This prevents abnormally high pressure from building up inside the weir.

計の水柱圧分の過圧防止装置となる。 Considering the air pressure at each position at this time, air layer above water seal pipe 9, first water seal pipe 3', H 2 mAq Overpressure prevention pipe 2, forming weir body Enveloping internal pressure 2×H 2 mAq. Note that H 2 is the height of the overpressure prevention pipe and the water seal pipe communication pipe submerged in the water of each water seal pipe. In other words, when water seal tubes are connected via a water seal communication pipe, the overpressure will be equal to the water column pressure of the sum of the heights of the overpressure prevention pipe submerged in water and the water seal communication pipe of the two water seal tubes. Acts as a prevention device.

置となる。 Although Figure 3 shows the case of two water seal tubes, the case of three or more water seal tubes can be considered in the same way as the case of two water seal tubes, and if the connected water seal tubes are submerged in water. This is an overpressure prevention device for the water column pressure equal to the total height of the pipe.

Because of this low water-sealing tube, there is no need to dig into the operation room or raise the height of the operation room building, making it economical. Furthermore, it is easy to supply water to the water seal tube.
