扭王字块安装智能引导系统的施工应用

Construction application of intelligent guidance system for accropode block installation

目前扭王字块水下可视化安装主要采用水下摄像机或声呐成像的方法进行,该方法对水域能见度要求高或传感器成本高,且难以实现关键参数的定量化控制。通过对扭王字块吊装工艺及验收要求进行分析,采用在履带吊、扭王字块等物体上加装传感器及空间点位计算程序设计等方式,研发出一套扭王字块安装智能引导系统。在防波堤工程施工现场开展典型段验证工作,实现了防波堤全断面的扭王字块可视化安装,使得高潮位下仍可进行扭王字块吊装,增加了施工作业窗口,有效提高了施工速度。

At present,the underwater visual installation of accropode block is mainly carried out by underwater camera or sonar imaging method,which requires high visibility of the underwater environment or high cost of the sensor,and it is difficult to achieve quantitative control of key parameters.Based on the analysis of the construction process and acceptance requirements of the accropode block,the intelligent guidance system for the installation of the accropode block is developed by installing sensors on the objects such as the crawler crane and the accropode block and building the calculation program of spatial points.The verification work is carried out on site by the typical section in the breakwater construction field,and the visual installation of accropode block in the whole section of the breakwater is realized.The system permits the installation work of the accropode block in the high water level condition,increases the construction period and improves the efficiency of construction work.
