There are many shortcomings in traditional installation of the breakwater wave board,such as short operating time during high tide,the difficulty of positioning,and the poor reinforcement effect of the components.This paper introduces an improved process for the installation and construction of the breakwater wave board of a yacht club project,i.e.installing steel plates on the pier of the breakwater and installing steel pendants on the top of the wave board,and connecting them during construction to achieve unsupported installation of the wave shield.This paper also elaborates the main construction procedures and carries out the force analysis of the wave baffle and breakwater. The results show that all parameters of this lifting method meet the installation requirements.This construction process may serve as reference for the installation of other unsupported components of the breakwater.
