Abstract

PURPOSE:To reduce the term and the cost of construction, by a method wherein a partial water filling box is mounted on a tank and the head pressurizing device mounted on the partial water filling box is subsequently operated to raise the pressure in the partial water filling box to prescribed head pressure. CONSTITUTION:When a test is performed by applying the water pressure of a prescribed water filling level 4 to a water filling pressure resistance testing range 2, a partial water filling box 3 is mounted to the side wall of a tank 1 at first so as to surround the water filling pressure resistance testing range 2 inside the side wall of the tank 1 and a first valve 7 is closed subsequently. Thereafter, it water is injected in the watertight section 5 in the partial water filling box 3, the distribution of water to the water filling pressure resistance testing range 2 becomes perfect. Next, if a flexible hose 6 is filled with water and the head part 6a of the hose 6 is hung up to the position of the prescribed water filling level of the tank 1, the pressure of the watertight section 5 becomes the same as that of the prescribed water filling level 4. Therefore, the same condition as that water is allowed to fill the tank 1 up to the prescribed water filling level 4 is applied to the water filling pressure resistance testing range 2. As mentioned above, work for the filling of a large quantity of water and the drainage thereof for the purpose of the partial water pressure test of the tank is reduced and the reduction in the term of and the cost of construction is attained.

To provide a pressure test method (partial filling of a tank) in which the pressure of the tank is increased to a specified head pressure.

〔作用〕[Effect]

部分水張シボックスをタンク本体の試験箇所に取シつけ

A flexible hose 6 is provided from the partial Minamata box 6, and a cylindrical head 6a is provided at the tip. In addition, the broken line 2 in the figure shows the Minamata pressure test range, and the broken line 4 shows the specified Minamata water level.

次にこの作用を説明する。Next, this effect will be explained.

れば、水俣耐圧試験範囲２に対する配水は完全となる。As shown in the figure, when testing the Minamata pressure test range 2 by applying the water pressure of the specified Minamata water level 4, first place the partial Minamata box 6 so that it surrounds the Minamata pressure test range 2 inside the side wall of the tank 1. and then close the first pulp 7. By injecting water into the watertight section 5 in the rear partially water-filled box filtration, water distribution to the Minamata pressure test range 2 is complete.
