従来、止水装置及びそのバッグは、先に本願考案者等が提案した特願平１−３ １６７７６号が存在する。 しかしながら、上記のようなバッグは以下に述べるような問題を有していた。 すなわち、図４は上記のようなバッグを示すもので、内側にゴムバッグ４２を 有し、外側に布バッグ４３を有する止水用バッグ４１の取付口部４４内にホ−ス ４５の流入口４６を臨ませ、取付口部４４の外周にクランプ４７を配設すると共 にホ−ス４５内にスリ−ブ４８を配設し、クランプ４７をスリ−ブ４８に圧締し て止水用バッグ４１をホ−ス４５に連結しており、使用時に収縮状態とした該止 水用バッグ４１を管路の管に取付した止水装置内から管に穿設したバッグ挿通用 孔を通して管内に配設すると、その際、大気圧と同圧な止水用バッグ４１内圧よ りも相当に高圧な管内圧により図示のように止水用バッグ内側のゴムバッグ４２ が図示のようにホ−ス４５の流入口４６内に押し込まれ、その際ゴムバッグ４２ の流入口の口縁４９に当接した部分が局部的に延伸されて損傷を受け、ひいては 止水用バッグ４１が気密性を失って使用に供し得なくなるという問題を有してい た。 Conventionally, Japanese Patent Application No. 1-316776 previously proposed by the present inventors has existed as a water stop device and its bag. However, the above bag has the following problems. That is, FIG. 4 shows such a bag as described above, in which a rubber bag 42 is provided on the inner side and a cloth bag 43 is provided on the outer side. 46, the clamp 47 is arranged on the outer periphery of the mounting opening 44, and the sleeve 48 is arranged in the hose 45. The clamp 47 is pressed against the sleeve 48 to stop water. The bag 41 is connected to the hose 45, and the water blocking bag 41, which is in a contracted state at the time of use, is inserted into the pipe from a water blocking device attached to the pipe of the pipeline through a bag insertion hole formed in the pipe. When installed, the rubber bag 42 inside the waterproof bag is hose as shown in the drawing due to the pipe internal pressure that is considerably higher than the internal pressure of the waterproof bag 41 that is the same as the atmospheric pressure. 45 is pushed into the inflow port 46 of the rubber bag 42. Abutting portions damaged is locally stretched to 9, it has a problem that eventually the waterproof bag 41 can not be put to use lost airtightness.

そこで本考案は、使用時に管路の管内に配設する際、管内圧によりゴムバッグ がホ−スの流入口内に押し込まれることを防止し、これによってゴムバッグの損 傷を防止する止水装置用バッグを提供し、もって上記従来技術の問題を解決しよ うとするものである。 Therefore, the present invention prevents the rubber bag from being pushed into the inlet of the hose by the internal pressure of the pipe when the pipe is installed in the pipe of the pipe during use, thereby preventing damage to the rubber bag. The present invention intends to solve the above-mentioned problems of the prior art by providing a bag for use.

すなわち、本願の第１の考案は、ゴムバッグ又は内側にゴムバッグを有する止 水用バッグにおいて、該止水用バッグの取付口部内に接続したホ−スの流入口を 前記ゴムバッグの厚さ以下の網目のネット状体で被覆したことを特徴とする止水 装置用バッグを要旨とするものであり、第２の考案はゴムバッグ又は内側にゴム バッグを有する止水用バッグにおいて、該止水用バッグの取付口部内に接続した ホ−スの流入口を前記ゴムバッグの厚さ以下の穴としたことを特徴とする止水装 置用バッグを要旨とするものである。 That is, the first invention of the present application is, in a waterproof bag having a rubber bag or an inner rubber bag, a hose inlet connected to an attachment opening portion of the waterproof bag having a thickness of the rubber bag. A gist of a bag for a waterproof device, which is characterized by being covered with a net-like body of the following mesh, and a second invention is a waterproof bag having a rubber bag or a rubber bag inside thereof. The gist of the bag for waterproofing device is characterized in that the inlet of the hose connected to the inside of the mounting opening of the water bag is a hole having a thickness equal to or less than the thickness of the rubber bag.

このようにした止水装置用バッグにあっては、止水使用に際し、収縮状態下に 管路の管内に配設すると、その際、大気圧と同圧な止水用バッグ内圧よりも相当 に高圧な管内圧により止水用バッグのゴムバッグがホ−スの流入口内に押し込ま れようとするが、該ホ−ス流入口に設けたゴムバッグの厚さ以下の網目のネット 状体又はゴムバッグの厚さ以下の穴が上記ゴムバッグを流入口内へ押し込むこと を防止する。 In such a waterproofing device bag, when the waterproofing device is installed in the pipe of the pipeline in a contracted state when the waterproofing is used, the pressure in the waterproofing bag at the same pressure as the atmospheric pressure is considerably higher than that. The high pressure inside the pipe tends to push the rubber bag of the water blocking bag into the inlet of the hose, but the net-like body or rubber of mesh size equal to or less than the thickness of the rubber bag provided at the inlet of the hose. Prevent holes below the thickness of the bag from pushing the rubber bag into the inlet.
【０００６】[0006]
次に本考案の実施例を図面に基づいて説明する。 図１、図２に示す実施例は、内側にゴムバッグ２を有し、外側に布バッグ３を 有する止水用バッグ１の取付口部４内にホ−ス５の流入口６を臨ませ、取付口部 ４の外周にクランプ７を配設すると共にホ−ス５内にスリ−ブ８を配設し、クラ ンプ７をスリ−ブ８に圧締して止水用バッグ１をホ−ス５に連結し、ホ−スの流 入口６をゴムバッグ２の厚さ９以下の網目１０〜１０のネット状体１１、例えば 網、布等のネット状体で被覆し、止水用バッグ１を軸線Ｘ−Ｘ方向に沿って畳ん だ収縮状態としている。 Next, an embodiment of the present invention will be described with reference to the drawings. In the embodiment shown in FIGS. 1 and 2, the water inlet 6 of the hose 5 is exposed to the inside of the attachment opening 4 of the waterproof bag 1 having the rubber bag 2 inside and the cloth bag 3 outside. A clamp 7 is provided on the outer periphery of the mounting opening 4, a sleeve 8 is provided in the hose 5, and the clamp 7 is pressed onto the sleeve 8 to fix the water blocking bag 1 to the hoses. -Connecting to the hose 5 and covering the inlet 6 of the hose with a net-like body 11 having meshes 10 to 10 having a thickness of 9 or less of the rubber bag 2, for example, a net-like body such as a net or cloth to stop water. The bag 1 is in a folded and contracted state along the axis XX.
【０００７】 このようにした本例の止水装置用バッグにあっては、止水使用に際し、上記収 縮状態下に管路の管内に配設すると、その際図１に示すように、大気圧と同圧な 止水用バッグ１の内圧よりも相当に高圧な上記管内圧によりゴムバッグ２がホ− スの流入口６内に押し込まれようとするが、該ホ−スの流入口６に設けたゴムバ ッグの厚さ９以下の網目１０〜１０のネット状体１１がゴムバッグ２を流入口６ 内へ押し込むことを防止する。この管内への配置後、ホ−ス５から空気又は流体 をゴムバッグ２内に送入して止水用バッグ１を膨張し、膨張した止水用バッグ１ で管内を閉鎖して止水する。In the water shut-off device bag of the present embodiment, when the water shut-off bag is used, when the water shut-off device bag is placed in the pipe of the pipe line under the above-mentioned constricted state, as shown in FIG. The rubber bag 2 tends to be pushed into the inlet 6 of the hose by the internal pressure of the pipe which is substantially higher than the internal pressure of the water blocking bag 1 having the same pressure as the atmospheric pressure. The net-like body 11 having meshes 10 to 10 having a thickness of 9 or less of the rubber bag provided in the above prevents the rubber bag 2 from being pushed into the inflow port 6. After the placement in the pipe, air or fluid is fed from the hose 5 into the rubber bag 2 to inflate the water blocking bag 1, and the inflated water blocking bag 1 closes the pipe to stop the water. .
【０００８】 次に図３に示す実施例は、前例同様、内側、外側にそれぞれゴムバッグ２２、 布バッグ２３を有する止水用バッグ２１の取付口部２４内にホ−ス２５の流入口 ２６を臨ませ、取付口部２４の外周にクランプ２７を配設すると共にホ−ス２５ 内にスリ−ブ２８を配設し、クランプ２７をスリ−ブ２８に圧締して止水用バッ グ２１をホ−ス２５に連結し、ホ−ス２５の流入口２６に臨ませたスリ−ブ２８ の端部をゴムバッグ２２の厚さ２９以下の穴３０となし、止水用バッグ２１を軸 線Ｘ−Ｘ方向に沿って畳んだ収縮状態としている。Next, in the embodiment shown in FIG. 3, similarly to the previous example, the inlet 26 of the hose 25 is provided in the mounting opening 24 of the water blocking bag 21 having the rubber bag 22 and the cloth bag 23 inside and outside respectively. , A clamp 27 is provided on the outer periphery of the mounting opening 24, and a sleeve 28 is provided in the hose 25, and the clamp 27 is pressed against the sleeve 28 to stop the water. 21 is connected to the hose 25, and the end of the sleeve 28 facing the inflow port 26 of the hose 25 is formed as a hole 30 having a thickness of 29 or less in the rubber bag 22 to form the waterproof bag 21. It is in a contracted state folded along the axis XX direction.
【０００９】 このようにした本例の止水装置用バッグにあっても、止水使用に際し、前例同 様に管内圧によりゴムバッグ２２がホ−スの流入口２６内に押し込まれようとす るが、該ホ−スの流入口２６に設けたゴムバッグの厚さ以下の穴３０がゴムバッ グ２２を流入口２６内へ押し込むことを防止し、前例同様にして管内を止水する 。Even in the case of the water shut-off device bag of this example, when the water shut-off is used, the rubber bag 22 tends to be pushed into the inlet 26 of the hose by the pipe internal pressure as in the previous example. However, the hole 30 having a thickness equal to or less than the thickness of the rubber bag provided at the inlet 26 of the hose prevents the rubber bag 22 from being pushed into the inlet 26, and the inside of the pipe is stopped in the same manner as in the previous example.
【００１０】 なお、これら実施例では、止水用バッグ１、２１としてそれぞれ、ゴムバッグ ２、２２の外側に布バッグ３、２３を有するものを示したが、本案は布バッグ３ 、２３を必ずしも必要とするものではなく、その場合止水用バッグとしてゴムバ ッグ２、２２を単体で用いる。In these examples, the water blocking bags 1 and 21 have the cloth bags 3 and 23 outside the rubber bags 2 and 22, respectively, but the present invention does not necessarily include the cloth bags 3 and 23. It is not necessary, and in that case, the rubber bags 2 and 22 are used alone as a waterproof bag.
【００１１】[0011]
以上説明したように、本考案の止水装置用バッグにおいては、使用時に管路の 管内に配設する際、管内圧によりゴムバッグがホ−スの流入口内に押し込まれよ うとするが、その際流入口に設けたゴムバッグの厚さ以下の網目のネット状体又 は穴が上記ゴムバッグを流入口内へ押し込むことを防止し、これによってゴムバ ッグの損傷を防止することができる。 As described above, in the waterstop bag of the present invention, when the bag is placed in the pipe of the pipeline during use, the rubber bag tends to be pushed into the inlet of the hose by the internal pressure of the pipe. It is possible to prevent the net-like body or the holes having a thickness equal to or less than the thickness of the rubber bag provided at the inlet from pushing the rubber bag into the inlet, thereby preventing damage to the rubber bag.
