Embodiment Construction

[0008] The method of destroying abandoned structures by using resonance at the same frequency first measures the natural frequency of the abandoned structures, and then installs multiple vibration sources around the abandoned structures. The measuring instrument is used to measure, and the measurement accuracy of the natural frequency is improved by the audio frequency method; the frequency of the driving force sent by the vibration source through the frequency synthesizer; the natural frequency is the horizontal natural frequency or the longitudinal natural frequency, and people can adopt the horizontal vibration or longitudinal vibration according to different environments. method to destroy the structure.

[0009] The method of using the same frequency resonance to destroy abandoned structures can be known in university physics, A=F / m*root (wo^2-w^2)+4*w^2*p^2, wo and w It is the natural frequency and the frequency of the driving force. When they are equal, the amplitude A ...

Abstract

The invention discloses a method for destroying a disused structure, in particular a method for destroying a disused structure by using same-frequency resonance. The method for destroying a disused structure by using same-frequency resonance is characterized by comprising the following steps of: measuring the natural frequency of a disused structure first and then installing multiple vibration sources around the disused structure, wherein the natural frequencies of the vibration sources are the same as that of the disused structure. Natural frequencies are measured by a natural frequency-measuring instrument; the natural frequency measuring accuracy is improved by employing an audio frequency method; the vibration sources send out a driving force frequency by a frequency synthesizer; and the natural frequency can be a transverse natural frequency or a longitudinal natural frequency. According to the invention, by using the vibration sources with the same natural frequencies as that of the structure, the structure is destroyed due to resonance; the energy resource, manpower and material resource are saved, the work efficiency is high and great convenience is brought to a user.

Description

(1) Technical field [0001] The invention relates to a method for destroying abandoned structures, in particular to a method for destroying abandoned structures by using resonance at the same frequency. (2) Background technology [0002] The current method of dismantling structures is to use machines to dismantle them bit by bit, and dismantling a structure can take as little as a few weeks or as much as a few months, which wastes manpower, material resources, and too much time. The same-frequency resonance method has been widely used in the fields of acoustics, machinery, chemical industry, analytical instruments, radio and electronics, medicine, geo-environmental engineering and economics, military affairs, teaching, and disaster and accident prevention and control. In the middle of the 18th century, a group of soldiers passed by on a 102-meter-long bridge in Angers, France. When they crossed the bridge with orderly steps under the command of the commander, the bridge sudde...
