Abstract
【解決手段】地上に設置される筐体2と、筐体2内から下方に垂設されて地下のゲートGに連結し、上端側のねじ部3aを介した送りねじ機構5によって上下動するねじ棒3と、ねじ棒3の下端側の軸胴部3b周りを気密するパッキン4と、を備えた開閉機1において、パッキン4を筐体2の内部に位置させる気密構造とした。
【選択図】 図1
Description
(1)水路内の水を考慮しての作業となるので作業効率が悪く、充分な安全対策が必要となる
(2)上向きの作業になるので作業がしづらい
(3)梯子等の足場を用意する必要がある
(4)パッキンや付随する固定具等を水路内に落とすおそれがある
1 開閉機
2 筐体
3 ねじ棒
3a ねじ部
4 パッキン
5 送りねじ機構
7 点検窓
8 軸受部材
