Description

technical field [0001] The invention relates to a resonance device for vibrating and sinking a large steel cylinder, in particular to a resonance device for vibrating and sinking a large steel cylinder that can make the overall structure more stable through the cooperation of a vibrating beam and a connecting beam, and can meet the requirements for the axis transmission of the exciting force. resonance device. Background technique [0002] In recent years, with the development of offshore artificial islands and coastal seawall revetment projects, the rapid embankment and island formation construction technology has become increasingly mature by vibrating and sinking large steel cylinder structures, and the construction technology has broad application prospects. With the increase of steel cylinder structure size, the increase of vibration resistance makes the number of hammer groups involved in vibration increase correspondingly. In order to ensure the smooth sinking of the...

Problems solved by technology

However, with the increase in the number of hammer bodies participating in the vibration, there are many problems in the structural rigidity and the transmission efficiency of the exciting force in the traditional design scheme. The structural form puts forward more stringent requirements to ensure the stiffness of the hammer group and the overall safety of the structure when it vibrates synchronously at high frequencies; It is necessary to take into account that the amplitude achieved by its total mass can damage the foundation soil; (3) With the increase in the number of vibratory hammers, the arrangement position of the vibratory hammers on the resonant beam will directly determine whether the eccentric vibration of the hammer group as a whole occurs
