Document Type and Number:
Japanese Patent JP2524212
Kind Code:
B2
Abstract:
PURPOSE:To supply dissolved oxygen to sea water within a revetment to enhance cleaning function by a method wherein numerous bottomless box-type air chamber units each provided with an opening on the front face and an exhaust tube on the upper face are overlaid and installed in the sea while air is supplied to the lowermost unit. CONSTITUTION:Numerous bottomless box-type air chamber units 1 having an opening 3 on the front face with an exhaust tube protruding downward from the upper face are overlaid in the sea and fixed by a connecting rod 6. Then with an air supply tube connected to the lowermost air chamber unit 1, air is supplied. The units 1 respective stages are formed with an air chamber 8 while air is flowed upward sequentially so that waves are suppressed as well as a contact area between the air and the sea water is increased thereby supplying sufficient dissolved oxygen to the sea water. It is thus possible to realize a wave shelter revetment for enhancing cleaning function of the sea water.
