Method and device for measuring verticality of offshore wind power steel pile

Abstract

The invention provides a method and device for measuring the verticality of an offshore wind power steel pile. The device comprises a double-shaft clinometer, a first data transfer radio and an error feedback device used for calculating, displaying and storing verticality and radial height difference signals of the wind power steel pile according to measured data of the double-shaft clinometer. The double-shaft clinometer is arranged on one plane of a pile hammer through a first shock absorber, the plane is parallel to the piling plane of the pile hammer, the first data transfer radio is arranged on the pile hammer through a second shock absorber, and the first data transfer radio and the error feedback device carry out data exchange through a wireless transmitting antenna. According to the method and device for measuring the verticality of the offshore wind power steel pile, the verticality of the wind powder steel pile can be really monitored in the whole process, piling efficiency is improved, and a reliable numerical value basis is provided for adjustment of the verticality of the wind power steel pile.

Description

technical field [0001] The invention relates to the technical field of offshore piling, in particular to a device and method for measuring the verticality of offshore wind power steel piles. Background technique [0002] At present, according to the requirements for piling construction of offshore wind power steel piles, it is necessary to control the verticality (slope) of a single pile within three thousandths. [0003] The conventional measurement method is to use theodolite to observe the edge of the pile to determine the degree of inclination of the pile in a certain direction. This measurement method needs to set up at least two instruments to observe in two directions perpendicular to each other at the same time. Its disadvantages are obvious: 1. The whole process of piling cannot be observed during the piling process, and the hammer can only be observed before and after a certain period of piling. ; 2. Because only the edge of the pile can be observed, it is limited...

AI Technical Summary

Problems solved by technology

Although this method can realize the whole process of measurement, there are still disadvantages: 1. The cost is high, and the installation and debugging are difficult; 2. The variable diameter section cannot be accurately measured; 3. Because the roundness of the whole pile is not uniform, the measurement error cannot be measured Avoid; 4. Since the instrument needs to be installed at a certain distance in the vertical direction, if the elevation of the pile top is lower than the elevation of the uppermost instrument, it cannot be measured
