本発明は、タンクの部分水張り耐圧試験方法に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pressure test method for partially filling a tank with water.
タンクの一部に対して規定水圧テストを必要とする場合
、従来はタンク全体に規定水位まで水を張ることKよっ
て、規定水位の水圧試験を行っていた。When a specified water pressure test is required for a part of a tank, conventionally the water pressure test at the specified water level has been carried out by filling the entire tank with water up to the specified water level.
従来のこの方法では、水俣耐圧試験の対象となる部分が
僅少な場合でも、タンク全体に規定水位まで水張シを行
うために多量の水を必要とし、更に水張シ、水抜き、排
水処理等に多くの設備、労力、時間を必要とした。With this conventional method, even if the area subject to the Minamata pressure test is small, a large amount of water is required to fill the entire tank with water to the specified water level, and additional steps are required for filling, draining, and wastewater treatment. etc. required a lot of equipment, labor, and time.
本発明はこのような問題点を解決するためになされたも
ので、部分水張ボックスをタンクに取付け、ついで部分
水張ボックスに取付けられた水頭圧加圧装置を操作して
部分水張ボックス内の圧力を規定水頭圧に加圧するよう
にしたタンクの部分水張)耐圧試験方法を提供する。The present invention has been made to solve these problems, and involves attaching a partially water-filled box to a tank, and then operating a water head pressurizing device attached to the partially water-filled box to increase pressure inside the partially water-filled box. 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.
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
た後、部分水張シボックスに備えられた水頭圧加圧装置
を操作して部分水張シボックス内の圧力を規定圧力とす
れば、タンク全体に規定圧力まで水張りしたときと同じ
水圧を試験箇所に与えることが出来る。After attaching the partial water filling box to the test location on the tank body, operate the water head pressurization device provided on the partial water filling box to bring the pressure inside the partial water filling box to the specified pressure. , it is possible to apply the same water pressure to the test location as when the entire tank is filled with water to the specified pressure.

し、4は規定水俣水位を示すものである。Further, a partial Minamata box 6 is attached to the inside of the tank 1 surrounding the opening of the nozzle 1a to form a watertight compartment 5. 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.
図に示されるように水俣耐圧試験範囲2に対し、規定水
俣水位4の水圧をかけて試験をする場合は、先ず部分水
俣ボックス6をタンク1の側壁の内側の水俣耐圧試験範
囲2を囲むように取付け、ついで第1パルプ7を閉じる
。この後部分水張りボックスろ内の水密区画5に注水す
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.
次に、フレキシブルホース6内に水を満した後、ホース
6の頭部6aをタンク1の規定水俣水位4の位置まで吊
り上げれば、水密区画5の圧力は規定水俣水位4と同じ
圧力となるから、前記水俣耐圧試験範囲2に対して、規
定水俣水位4に水を張ったと同じ条件が与えられる。Next, after filling the flexible hose 6 with water, if the head 6a of the hose 6 is lifted up to the specified Minamata water level 4 of the tank 1, the pressure in the watertight compartment 5 will be the same as the specified Minamata water level 4. Therefore, the same conditions as when water is filled at the specified Minamata water level 4 are given to the Minamata pressure test range 2.
尚本実施例はタンク1のノズル1&と第1パルプ7を試
験範囲2にとり入れであるが、本発明はこれに限るもの

様の効果がある。In this embodiment, the nozzle 1& of the tank 1 and the first pulp 7 are included in the test range 2, but the present invention is not limited to this, and the same effect is obtained wherever the partial Minamata box 3 is attached. Needless to say. Further, the method of applying water pressure to the watertight compartment 5 is not limited to the flexible hose 6, and the same effect can be obtained by using a pressure gauge adding pressure device.
本発明によれば、部分水俣ボックス内の水圧力を自由に
変化させることが出来ることによシ、タンクの一部の水
圧テストのため、大量の水の張り込み、排水等の作業を
削減することが可能となシ、工期及び工費の減少に大き
な効果がある。According to the present invention, since the water pressure in the partial Minamata box can be freely changed, it is possible to reduce the work of filling a large amount of water, draining water, etc. in order to test the water pressure of a part of the tank. This has a great effect on reducing construction time and construction costs.
