【課題を解決するための手段】[Means to solve the problem]

この発明は、泥水チャンバー2の隔壁3に設けたマンロック4の先端側の開口 部5の内側周辺に、戸袋状のドアー収納室6を設け、このドアー収納室6から開 口部5を閉鎖する位置にかけて隔壁3面に沿ってスライド自在な内ドアー7を設 け、この内ドアー7の戸当たり面の周囲に内部が中空の弾性体からなるシール材 8を取付け、このシール材8にその中空部9の内部圧力を調整するためのエアー パイプ10を接続してなる泥水加圧シールド機におけるマンロックの内ドアー装 置を提案するものである。 This invention provides an opening on the tip side of the manlock 4 provided in the partition wall 3 of the muddy water chamber 2. A door pocket-shaped door storage chamber 6 is provided around the inside of the portion 5, and the door can be opened from this door storage chamber 6. An inner door 7 is provided that can freely slide along the partition wall 3 to a position where the mouth portion 5 is closed. A sealing material made of an elastic body with a hollow interior is installed around the door stop surface of the inner door 7. 8 is installed, and air is installed in this sealing material 8 to adjust the internal pressure of the hollow part 9. Inner door installation of Manlock in muddy water pressurized shield machine connected with pipe 10 This is a proposal for a new location.

【作用】[Effect]

内ドアー7の閉鎖時にはドアー収納室6から内ドアー7を引き出して開口部5 を閉鎖すると共に、エアーパイプ10を介してシール材8の中空部9内にエアー を圧送し、膨張したシール材8により開口部5の周囲を密閉する。 When the inner door 7 is closed, the inner door 7 is pulled out from the door storage chamber 6 and the opening 5 is closed. At the same time, air is introduced into the hollow part 9 of the sealing material 8 through the air pipe 10. is fed under pressure, and the periphery of the opening 5 is sealed by the expanded sealing material 8.

【0007】 また、シールドの立坑到達、地中接合時等においてマンロックの内ドアーを開 放する場合、エアーパイプ10を介してシール材8の中空部9内のエアーを抜き 、シール材8を収縮させて内ドアー7に作用する土砂などの圧力を緩め、この状 態で内ドアー7をドアー収納室6内にスライド移動して開口部5を開放する。[0007] In addition, the inner door of the manlock can be opened when the shield reaches the shaft or connects underground. When releasing the air, air in the hollow part 9 of the sealing material 8 is removed via the air pipe 10. , the sealing material 8 is contracted to relieve the pressure of dirt, etc. acting on the inner door 7, and this condition is In this state, the inner door 7 is slid into the door storage chamber 6 to open the opening 5.

【実施例】【Example】

泥水加圧シールド機1の泥水チャンバー2の隔壁3の外側にマンロック4が取 付けられ、このマンロック4の先端に対応した位置の隔壁3に設けた開口部5の 内側周辺に、戸袋状のドアー収納室6が設けられ、また隔壁3の内側には、ドア ー収納室6から開口部5を閉鎖する位置にかけて隔壁3面に沿ってスライド自在 な方形板状の内ドアー7が設けられている。 A manlock 4 is attached to the outside of the bulkhead 3 of the muddy water chamber 2 of the muddy water pressurization shield machine 1. The opening 5 provided in the partition wall 3 at a position corresponding to the tip of the manlock 4 A door pocket-shaped door storage chamber 6 is provided around the inside, and a door is provided inside the bulkhead 3. - Can be slid freely along the partition wall 3 from the storage chamber 6 to the position where the opening 5 is closed A rectangular plate-shaped inner door 7 is provided.

【0009】 内ドアー7は、その戸当たり面の周囲に内部が中空のゴム等の弾性体からなる シール材8が取付けられ、このシール材8にその中空部9の内部圧力を調整する ためのエアーパイプ10が接続され、バルブ11を介して中空部9内にエアーを 圧送するか、または内部エアーを排出することにより、中空部9内の圧力を調整 してシール材8を膨張収縮できるように構成されており、ドアーの閉鎖時におい てシール材8を膨張することによって内ドアー7の周囲を密閉することができ、 またドアー開放時においてシール材8を収縮させることによって内ドアー7に作 用する圧力を緩めることができる。[0009] The inner door 7 is made of an elastic body such as rubber that is hollow inside around the door stop surface. A sealing material 8 is attached, and this sealing material 8 adjusts the internal pressure of its hollow part 9. An air pipe 10 is connected to supply air into the hollow part 9 through a valve 11. Adjust the pressure inside the hollow part 9 by pumping or discharging internal air. The seal material 8 is configured to expand and contract when the door is closed. By expanding the sealing material 8, the area around the inner door 7 can be sealed. Also, by contracting the sealing material 8 when the door is opened, the inner door 7 is The pressure used can be relaxed.

【0010】 内ドアー7の側面には、ドアー収納室6内から開口部5の側縁にかけて設けた ガイドレール12上を転動するローラー13が取付けられている。0010 A hole is provided on the side of the inner door 7 from the inside of the door storage chamber 6 to the side edge of the opening 5. A roller 13 that rolls on a guide rail 12 is attached.

【0011】 ドアー収納室6の開口部の周縁及びガイドレール12の側縁部には内ドアー7 に圧着してシールするパッキン14,15が設けられ、内部への土砂などの侵入 を防止している。[0011] An inner door 7 is provided at the periphery of the opening of the door storage chamber 6 and the side edge of the guide rail 12. Packings 14 and 15 are provided that are crimped and sealed to prevent dirt, etc. from entering the interior. is prevented.

【0012】 隔壁3には、内ドアー7の閉鎖時にその先端部が位置する前方の部分にジャッ キ16が取付けられ、内ドアー7が土砂などにより強固に固着している場合に、 先端を強制的に押圧して固着を解除し、初期的に若干スライド移動させることに より、その後円滑にスライド移動できるようになっている。0012 The bulkhead 3 has a jack at the front part where the tip of the inner door 7 is located when it is closed. When the key 16 is installed and the inner door 7 is firmly fixed due to earth and sand, I decided to forcibly press the tip to release the fixation and initially make it slide slightly. This allows for smooth sliding movement afterwards.

【0013】 なお、マンロック4の後端には外ドアー17が設けられている。[0013] Note that an outer door 17 is provided at the rear end of the manlock 4.

【考案の効果】[Effect of the idea]

以上の通りこの考案によれば、内ドアーの閉鎖時にエアーパイプを介してシー ル材の中空部内にエアーを圧送して、膨張したシール材により開口部周囲を密閉 することができる。 As described above, according to this invention, when the inner door is closed, the air pipe is Air is forced into the hollow part of the material, and the expanded sealant seals the area around the opening. can do.

【0015】 また、シールドの立坑到達、地中接合時等においてマンロックの内ドアーを開 放する場合に、エアーパイプを介してシール材の中空部内のエアーを抜き、シー ル材を収縮させて内ドアーに作用する土砂などの圧力を緩め、この状態で内ドア ーをドアー収納室内に円滑にスライド移動して開口部を容易に開放することがで き、隔壁を解体することなく土砂撤去作業等の危険作業を確実に行うことができ る。[0015] In addition, the inner door of the manlock can be opened when the shield reaches the shaft or connects underground. When releasing the seal, remove the air from the hollow part of the seal material through the air pipe, and The material is contracted to relieve the pressure of dirt, etc. that acts on the inner door, and in this state the inner door is closed. The opening can be opened easily by sliding the door smoothly into the door storage chamber. This allows dangerous work such as earth removal work to be carried out reliably without dismantling the bulkhead. Ru.

【0016】 また、ドアーがスライド式であるため、チャンバー寸法を小さくとれる。[0016] Additionally, since the door is a sliding type, the chamber size can be kept small.
