Underwater measurement method for steel pipe pile of jacket foundation by adopting pile-first method
The invention discloses an underwater measurement method for a first pile method jacket foundation steel pipe pile. The underwater measurement method comprises the steps that firstly, four measurement tool frames are manufactured; secondly, four measuring tool frames with long base line beacons are hoisted to the top faces of the four steel pipe piles; 3, each long baseline beacon carries out tracking measurement on the other three long baseline beacons to obtain the distance between piles; 4, mounting and fixing pressure sensors on the measuring tool frames on the first pile, holding and moving the pressure sensors by a diver, and placing the pressure sensors on each measuring tool frame for 1-2 minutes; fifthly, the difference value between data collected by the movable pressure sensor and data collected by the fixed pressure sensor is calculated, and the pile top height difference is obtained; step 6, measuring the gradient of the steel pipe pile by using a built-in attitude sensor of the long baseline beacon; and 7, according to the pile top height difference of the four steel pipe piles, the gradients of the pile top planes of the four steel pipe piles are calculated. According to the invention, the state of the sunk steel pipe pile can be measured with high precision.
本发明公开了一种先桩法导管架基础钢管桩的水下测量方法，包括：步骤一，制作四个测量工装架；步骤二，将四个带有长基线信标的测量工装架吊装到四根钢管桩的顶面上；步骤三，每个长基线信标均对其余三个长基线信标进行跟踪测量，得到桩间距离；步骤四，在1号桩上的测量工装架上安装固定压力传感器，潜水员手持移动压力传感器在每个测量工装架上放置1～2分钟；步骤五，计算移动压力传感器采集的数据与固定压力传感器采集的数据之间的差值，即得到桩顶高差；步骤六，利用长基线信标内置的姿态传感器测量钢管桩的倾斜度；步骤七，根据四根钢管桩的桩顶高差，计算四根钢管桩的桩顶平面的倾斜度。本发明能对沉桩后的钢管桩的状态进行高精度测量。
