Title: Wavebreaking method
Inventor: WATARAI HIDEAKI
IPC: E02B3/06
Filed: 1986-10-06
Abstract: PURPOSE:To save the cost of construction work as well as maintain natural landscope by a method in which a flexible curtain is almost horizontally positioned in sea, and waves resulting from phase difference to be occurred on the bank side of the curtain is collided with waves from the offing to brake the waves. CONSTITUTION:A breakwater structure consists of a sheet of horizontal tent 1 made of a flexible material such as rubber and positioned to be always sunk in the sea in an almost horizontal state and struts 2 made of a rigid material such as metal to hold the peripheral and several positions of the tent 1 almost horizontally in water. The depth of the tent 1 is determined from the wavelength and permeation rate of incoming waves and the struts 2 are set into the seabed as needed. Waves 3 resulting from the phase difference to be occurred on the bank side collide with waves coming from the offing to dump the their energy, resulting in the breakage of waves.
