Monitoring method and monitoring system for underwater grouting construction process of offshore wind power jacket
The invention discloses an offshore wind power jacket underwater grouting construction process monitoring method and a monitoring system, a plurality of temperature sensors connected with a data processing device are arranged in a vertical array in an annular space, needing to be grouted, of a jacket foundation, and grouting is carried out on the annular space between a foundation pipe pile and an insertion leg from a bottom grouting opening of the jacket; in the process that slurry rises along the annular space, the temperature sensors are used for monitoring and analyzing the temperature in the annular space in real time, the arrival position and the rising speed of the grouting material are determined according to the time when the temperature gradient suddenly becomes large, and when the temperature gradient monitored by the top temperature sensor suddenly becomes large, the grouting material is sent to the annular space. And judging that the annular space is filled with the slurry, and stopping grouting. The provided method and monitoring system can accurately monitor the ascending condition of the grouting material, stop grouting construction in time when the grouting material is full, avoid waste of the grouting material, facilitate on-site arrangement and construction, and are suitable for underwater grouting engineering of the offshore wind power jacket.
本发明公开了一种海上风电导管架水下灌浆施工进程监测方法及监测系统，在导管架基础需灌浆的环形空间中，沿竖向阵列布设与数据处理装置连接的多个温度传感器，由导管架的底部灌浆口向基础管桩与插腿之间的环形空间灌浆，在浆料沿着所述环形空间上升过程中，通过各所述温度传感器对环形空间内部温度实时监测及分析，由温度梯度突然变大的时间确定灌浆料到达位置和上升速度，当顶部温度传感器监测到的温度梯度突然变大时，判断环形空间的浆料灌满，停止灌浆。所提供的方法及监测系统能够准确监测灌浆料上升状况，在灌满时及时停止灌浆施工，避免浆料浪费，便于现场布置施工，适合于海上风电导管架水下灌浆工程。
