Abstract

Provided is an offshore large-diameter single-pile sinking measurement method. The method includes the following steps of pile stabilizing platform positioning and elevation leveling; tower cylinder door direction measurement; single pile perpendicularity measurement; flange levelness measurement; single pile elevation measurement; and measurement acceptance. According to the offshore large-diameter single-pile sinking measurement method, the precision requirement in the steel pipe pile single pile foundation sinking process is improved, the steel pipe pile plane positioning, the pile body perpendicularity, the flange flatness and the tower drum door direction are accurately controlled, and the single pile construction design and standard requirements are met.

Description

technical field [0001] The invention relates to the technical field of offshore wind power engineering, in particular to a method for measuring large-diameter single piles at sea. Background technique [0002] Before sinking large-diameter single piles at sea, GPS is used to locate the plane coordinates of the pile-stabilizing platform. Offshore construction areas are mainly concentrated in deep-water areas on the continental shelf. The signals in these areas are poor, and signal delays or failures may occur when using GPS and other signal receiving measuring instruments. Due to problems such as receiving signals, it is impossible to adjust the plane position of the pile stabilization platform in real time. [0003] In addition, due to the large diameter of the single pile in offshore construction, the pile length reaches about 100m, and the pile weight is about 1600t. Before self-sinking, the jack is used to limit the position of the pile body, which will cause the vibratio...
