WATER CONTROL GATE AND ACTUATOR FOR THE SAME

Title:

WATER CONTROL GATE AND ACTUATOR FOR THE SAME

Document Type and Number:

Japanese Patent JP2011017247

Kind Code:

A

Abstract:

To provide an alternative to an existing water control gate for a low dam height at a low cost, which can be easily transported and installed, and does not need a heated contact plate at work in winter.

A manufacturing operating device and a method are improved for the water-control gate 24, a related expansion actuator 203, and a related seal. The design of an air joint is improved, the stress of an expanded bladder is eliminated, and the strength of an expansion-type bladder is reinforced. The sliding friction related to a water gate is mitigated, and the manufacturing of a contact seal, other water-storage seals, and a gate panel 24 are improved. Then water-storage structure coping with traffic and the improved operating efficiency of a water gate panel system are provided, and a manufacturing technology of nappe aeration, a hinge, and the bladder are improved.
