Description

Technical Field

[0001] The utility model relates to the technical field of wind power equipment construction, in particular to a device for checking the flatness of secondary grouting of a wind power foundation. Background Art

[0002] At present, with the continuous development of my country's wind power industry, the height of wind turbine towers is increasing, and the requirements for the flatness of the secondary grouting of the foundation of the mixed tower wind turbine are becoming more stringent. During the construction of the traditional flexible steel tower, the anchor plate of the wind turbine foundation is pre-adjusted to ensure that the flatness of the anchor plate is within 2mm, and then the secondary grouting is performed. However, since the foundation of the mixed tower wind turbine needs to be prestressed and stretched, there is no foundation anchor plate, so the secondary grouting needs to be performed directly, so that the secondary grouting in the grouting groove is level with the top surface of the foundation, and then the mixed tower is installed. This puts higher requirements on the flatness of the secondary grouting of the foundation of the mixed tower wind turbine.

[0003] In the prior art, there are two common ways to detect the flatness of the secondary grouting of the mixed tower fan foundation: 1. Manual observation, observing the surface of the fan foundation to ensure that there is no unevenness; 2. Multi-point pre-embedded steel bars, burying multiple steel bars in the grouting groove in advance, and using tools (such as: level and level ruler) to determine the height of the pre-embedded steel bars, which is the grouting height. However, direct manual observation will be inaccurate and can only be roughly checked. Using pre-embedded steel bars and then directly detecting with tools will be affected by the secondary grouting surface itself, resulting in inaccurate measurement, and the efficiency of both methods is too low.
