（実 施 例）
第１図は本発明に係るテスト方法の一実施例を示す概略
説明図であり、第２図は、本発明のテスト方法の一例を
示すフローチャート図である。(Embodiment) FIG. 1 is a schematic explanatory diagram showing an embodiment of the test method according to the present invention, and FIG. 2 is a flowchart diagram showing an example of the test method of the present invention.
同図において、壁１００と床スラブ１０１ａ。In the figure, a wall 100 and a floor slab 101a.
１０１ｂとで囲まれた部分の排水管がテスト対象部であ
る。The part of the drain pipe surrounded by 101b is the part to be tested.
先ず、テスト対象部の排水立管１内に２つの封鎖器３ａ
、３ｂを挿入し、上下に配置された両封鎖器３ａ、３ｂ
間に排水立管１の横走り枝管２への分岐部１ｂが位置す
るようにする。First, two sealers 3a are installed in the drainage standpipe 1 of the part to be tested.
, 3b are inserted, and both sealers 3a and 3b are placed above and below.
A branching part 1b of the drainage standpipe 1 to the horizontal branch pipe 2 is located in between.
そして、本例では、図示するように、２つの封鎖器３ａ
、３ｂを紐状物（ここでは鎖）１０で連結した二連式封
鎖器を用いている。この鎖１０は排水立管１の上部開口
部１ｂまで延び、この開口部１ｂで鎖１０を操作するこ
とにより２つの封鎖器３ａ及び３ｂ間の距離を長短調節
できるように構成されている。In this example, as shown in the figure, two sealers 3a
, 3b connected by a string-like object (here, a chain) 10 is used. This chain 10 extends to the upper opening 1b of the drain standpipe 1, and is configured such that by operating the chain 10 at this opening 1b, the distance between the two blockers 3a and 3b can be adjusted to be longer or shorter.
さらに封鎖器３ａ、３ｂは、排水立管１外上方に配設さ
れた水圧測定用ゲージｌｌａ付の水ポンプ１１に連繋さ
れており、その水ポンプ１１から所定の圧力（４〜５
ｋｇ ／ ｃｄ ）の水を封鎖器３ａ。Further, the blockers 3a and 3b are connected to a water pump 11 equipped with a water pressure measuring gauge lla disposed outside and above the drainpipe 1, and from the water pump 11 a predetermined pressure (4 to 5
kg/cd) water blocker 3a.
３ｂに注入することによりその胴部を膨出させ、これに
より胴部が排水立管１の内壁に密着し、封鎖される構造
のものを用いている（ステップ１０１〜１０５）。3b is injected into the drain pipe 1 to inflate its body, thereby causing the body to come into close contact with the inner wall of the drain standpipe 1 and seal it (steps 101 to 105).
次いで、横走り枝管２に設けられている各分岐管４ａ、
４ｂの開口部を閉塞する。Next, each branch pipe 4a provided in the horizontally running branch pipe 2,
4b is closed.
本例では、分岐管４ａはユニットバスの排水口１１に接
続されおり、市販の閉塞治具では密閉できないため、こ
の排水口１１を粘土５ａで閉塞する。また、分岐管４ｂ
を市販の閉塞治具５ｂで閉塞する。この閉塞治具５ｂは
、例えばボルトナツト等を締めることにより胴部が膨出
し、分岐管４ｂの内壁に密着する構成のものを用いる。In this example, the branch pipe 4a is connected to the drain port 11 of the unit bath, and since it cannot be sealed with a commercially available closing jig, the drain port 11 is closed with clay 5a. In addition, branch pipe 4b
is closed using a commercially available closing jig 5b. This closing jig 5b has a body that bulges out by tightening a bolt/nut, for example, and comes into close contact with the inner wall of the branch pipe 4b.
更に、分岐管４Ｃにアダプター１２を取付け、このアダ
プター１２にエアー圧測定用ゲージ１３を介してエアー
ポンプ１４を接続する（ステップ１０６．１０７）。Further, an adapter 12 is attached to the branch pipe 4C, and an air pump 14 is connected to the adapter 12 via an air pressure measuring gauge 13 (steps 106 and 107).
次に、エアーポンプ１４の運転を開始し、封鎖器３ａ、
３ｂ間の排水立管１．横走り枝管２１分岐管４ａ−４ｃ
内をエアー圧３００〜５００ ｍｎ Ａｑ５本例では５
００ｍｍＡｑにする（ステップ１０８）。ここで、エア
ー圧を上記範囲に設定するのは以下の理由からなる。Next, the operation of the air pump 14 is started, and the blocker 3a,
Drain standpipe between 3b1. Horizontal branch pipe 21 branch pipe 4a-4c
Air pressure 300 to 500 mn Aq5 in this example
00 mmAq (step 108). Here, the reason why the air pressure is set within the above range is as follows.
すなわち、次工程で具体的な漏洩箇所を知るため塗布す
る漏洩検知液として石鹸液を使用するが、上記のエアー
圧が余り低すぎると、石鹸液膜の表面張力が大きすぎて
、石鹸液膜が発泡することはない。逆に、余り高すぎる
と、例えば８００〜１０００１００Ｏでは石鹸液膜の表
面張力がこの圧力に耐えることができず、石鹸液膜は瞬
時に破壊し、エアーは外気へ漏れてしまい、石鹸液膜の
発泡を確認することができない。In other words, soap liquid is used as a leak detection liquid to be applied in the next process to determine the specific leakage location, but if the air pressure mentioned above is too low, the surface tension of the soap liquid film will be too high and the soap liquid film will will not foam. On the other hand, if the temperature is too high, e.g. 800-1000100O, the surface tension of the soap film will not be able to withstand this pressure, and the soap film will instantly break and air will leak into the outside air, causing the soap film to deteriorate. Foaming cannot be confirmed.
従って、この場合は、エアー圧を３００〜５００ｍｍＡ
ｑ、好ましくは４００〜５００ｍｍＡｑとすることが肝
要である。Therefore, in this case, the air pressure should be set to 300 to 500 mmA.
q, preferably 400 to 500 mmAq.
この後、１５分間で、排水立管１．横走り枝管２、各分
岐管４ａ〜４Ｃ及びこれらの管の接続部に漏洩検知液（
本例では石鹸液）をかけ、石鹸液膜の発泡部１７の有無

となく、漏洩エアーを受は入れて膨らむ（発泡する）。After this, for 15 minutes, drain standpipe 1. Leak detection liquid (
In this example, a soap solution) is poured on the soap solution film, and the presence or absence of foamed portions 17 in the soap solution film is checked, and whether or not the above-mentioned air pressure decreases is checked (steps 109 to 113). At this time, if a leak exists, the air supplied from the air pump 14 will leak outward from the leak, and the leaked air will cause the leak detection liquid coating film applied to the leak to spread outward. to strengthen Then, the coating film absorbs the leaked air and expands (foams) without breaking due to its surface tension.
従って、この膨らみ部（発泡部）を探せば、漏洩部を容
易に検知することができる。Therefore, by looking for this bulging part (foaming part), the leakage part can be easily detected.
なお、上記のように検査時間を１５分としたのは、発泡
に要する時間に加え、上記発泡部を確実に確認するため
の検査時間をも考慮したものであり、少なくとも５分は
必要である。The reason for setting the inspection time to 15 minutes as mentioned above is to take into account the time required for foaming as well as the inspection time to reliably confirm the foamed area, so at least 5 minutes is necessary. .

However, if the surface tension is larger (smaller) than the soap liquid film, it may be changed as necessary. If the surface tension is larger (lower) than the soap liquid film, the pressure L-r may be higher (lower) than the air pressure shown in -. 4. If the pressure is too low, air leakage may occur, so a higher air pressure is required.
また、以上の実施例は、屋内↑１］水管を対象に（−１
