300 MW海上风电机基础结构垂直度监测方法
|
摘要
垂直度监测是海上风电单桩基础结构施工的一项重要内容,施工企业在垂直度监测中普遍通过停工并使用全站仪进行监测,这极大地影响了施工效率。文章依托国华东台300 MW海上风电项目,采用液压冲击锤间接测量法监测桩体的垂直度,与采用全站仪垂直度测量的监测结果相比,采用液压冲击锤间接测量法监测信息效率高、精度符合要求。
Verticality monitoring is an important part of the construction of offshore wind power single pile foundation structure. Construction enterprises generally use stoppage total station monitoring in verticality monitoring, which affects construction efficiency. This paper relies on Guohua Dongtai 300 MW offshore wind power project and uses hydraulic impact hammer. The indirect measurement method is used to obtain the verticality of the pile. The monitoring results of the total station verticality measurement are used for comparison. The results show that the monitoring method has high monitoring efficiency and accuracy, and is applicable widely.
