Abstract

The invention belongs to the technical field of wind power generation tower drum and tower drum foundation monitoring, and discloses a fabricated concrete tower drum foundation monitoring method, which comprises the following steps of: arranging a soil pressure gauge at the bottom of a foundation bottom plate according to the orientations of four determined measuring points; at least one strain gauge measuring point is arranged in each measuring point direction on a plate top circumferential rib, a plate top radial rib, a plate bottom circumferential rib, a plate bottom radial rib, a circular truncated cone vertical rib and a bracket corner rib of the foundation bottom plate and in concrete around the foundation bottom plate; the strain gauge measuring points are grouped and then are connected with the signal acquisition device through the line concentration box in the corresponding measuring point direction; and after the foundation concrete is poured, the signal acquisition device performs data acquisition and monitors the measuring points of the strain gauges and the detection data of the soil pressure gauges. According to the invention, the internal force of the foundation slab, the corbel corner rib and the circular truncated cone vertical rib and the settlement amount of the foundation slab can be monitored, so that real-time health monitoring of the foundation is realized.

Description

technical field

[0001] The invention relates to the technical field of wind power generation tower and tower foundation monitoring, in particular to a method for monitoring the foundation of an assembled concrete tower. Background technique

[0002] Wind power projects are gradually developing towards low wind speed and high shear areas. The height of the wind turbine tower is gradually increased from below 100m to 120m, 140m or even higher. In the wind turbine tower above 100m, the traditional steel tower Due to the defects of light weight, small stiffness, small damping, and resonance caused by the frequency close to the working frequency of the fan, the advantages of the concrete tower have been further revealed, and the application has become more and more extensive.

[0003] Considering factors such as quality and construction period, concrete towers are generally assembled in the form of prefabricated tower tube sections in the factory, assembled section by section on ...
