The invention provides a measuring device for the contact state of the inner wall of a steel pipe pile and core concrete of an offshore wind farm. The bottom of the steel pipe pile sinks to fresh rock, a core concrete reinforcement cage is arranged in the steel pipe pile after the steel pipe pile sinks, and the reinforcement cage and the inner wall of the steel pipe pile are spaced evenly so thata protective layer can be formed. The measuring device comprises a protective barrel which is fixed to the reinforcement cage. The end of the protective barrel is connected with a pressure transmission plate. One end face of the pressure transmission plate is right opposite to the inner wall of the steel pipe pile, and the other end face of the pressure transmission plate is provided with a protruding connection part. A pressure sensor is arranged in the connection part, and the connection part is located in the protective barrel. The invention further provides a measuring method for the contact state of the inner wall of the steel pipe pile and the core concrete of the offshore wind farm, and therefore the contact state of the steel pipe pile and the core concrete can be monitored. The measuring device is simple in structure and convenient to install and adjust, the pressure sensor is prevented from being affected in the casting construction process by arranging the protective barrel,and value precision is ensured.
Description
technical field [0001] The invention relates to the field of offshore wind farms, in particular to a measuring device and method for measuring the contact state between the inner wall of a steel pipe pile and core-filled concrete in an offshore wind farm. Background technique [0002] According to the construction site, wind farms can be divided into onshore and offshore. Compared with onshore wind farms, offshore wind farms have the advantages of high wind speed, long effective power generation time and no land occupation. my country's offshore wind farm construction is in its infancy and is about to usher in a stage of rapid development. The foundation design and construction of wind turbines is the key work in the construction of offshore wind farms, and it is also a key factor affecting the investment in offshore wind farms. Affected by ocean tides, waves, and currents, as well as special requirements during the installation and operation of wind turbines, the foundati...
