SLUICE GATE - TERATA HIROSHI

Title:

SLUICE GATE

Document Type and Number:

WIPO Patent Application WO/2018/037437

Kind Code:

A1

Abstract:

Provided are a tank placement, a double cross-section restraint, a side roller block, a retractable reaction roller, a retractable bottom water stop, a reaction shaft, a retractable side water stop, a door groove insertion step, and a stress reduction cross-section restraint in order to achieve an emerging-type retractable sluice gate that uses a cost-effective torsional structure. The tank placement allows a door body being operated to open and close while submerged. The double cross-section restraint allows coping with pressure from a storm tide and pressure from a tidal current that are significantly different conditions. The side roller block, the retractable reaction roller, and the retractable bottom water stop resolve spatial interference that occurs with opening and closing during construction and during maintenance management. A cross-section restraint point that receives a large load can be provided in a narrow spot in a housing space by providing a compact reaction shaft. Damage to a rubber side water stop is prevented with the retractable side water stop and door groove insertion step. The storm tide pressure torsional moment due to the stress reduction cross-section constraint is reduced by half by utilizing the door body buoyancy.
