透空式防波堤下挡浪板无支撑安装施工技术

Installation technology of wave shield of air-permeable breakwater under unsupported condition

传统的防波堤下挡浪板安装过程存在诸多不足,主要表现为赶潮水作业时间短、定位难度大、构件加固效果不佳等。介绍某游艇会工程防波堤下挡浪板安装施工的改进工艺:在防波堤墩台预埋工字钢固定点,并在挡浪板顶部预制钢挂件,施工过程中将工字钢固定点与挡浪板钢挂件连接,实现挡浪板的无支撑安装。同时,对主要施工工序进行阐述,并对下挡浪板的安装施工进行受力分析。结果表明该吊装方式的工字钢受力强度、剪应力强度、刚度以及墩台抗压情况均满足安装要求。该施工工艺可为今后防波堤无支撑构件的安装提供参考。

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.
