Description
Technical Field
[0001] The invention relates to the technical field of vibration isolation grooves, in particular to a sandwich multi-layer assembled vibration isolation groove. Background Art
[0002] With the continuous development and progress of human society, the problems caused by vibration are becoming more and more widespread and increasing in number. The vibrations generated by our production and life affect our lives all the time, and even threaten many buildings in my country with extremely high cultural and historical value and great humanistic significance. In particular, the vibrations caused by building or road construction and traffic vibrations. Vibration waves are vibrations that spread from the vibration source to all directions, referring to elastic waves that radiate from the vibration source to all directions. According to the propagation mode, they can be divided into three types: longitudinal waves (P waves), transverse waves (S waves) (both longitudinal waves and transverse waves are body waves) and surface waves (L waves).
[0003] Research has found that vibration damage to buildings is mainly manifested in the following three aspects:
[0004] 1. Transverse waves cause buildings to sway horizontally, resulting in damage to the buildings, and are very destructive. It is equivalent to applying a horizontal force to the building back and forth repeatedly. When the size and deformation caused exceed the limit of the building beam structure to resist vibration, the entire building will tilt or topple, resulting in damage;
[0005] 2. Longitudinal waves cause buildings to shake up and down. As some buildings are very old, their vertical stability is poor. When the vibration is large, the columns on the bottom floor, which serve as the load-bearing structure, will instantly increase the dynamic load. Combined with the deadweight of the upper part, when the load-bearing capacity of the columns on the bottom floor is exceeded, the columns on the bottom floor will collapse and cause damage.
[0006] 3. Buildings are subjected to long-term disturbances in the foundation soil caused by surrounding vibration sources and the effects of low-frequency and micro-vibrations. The buildings will suffer permanent and irreversible fatigue damage, resulting in a significant decrease in building safety and the appearance of various diseases.
[0007] The vibration isolation measure of the vibration isolation trench is to set up a vibration isolation barrier on the path of vibration wave propagation to destroy the propagation path of the vibration wave, causing the loss of vibration wave energy, so as to reduce or even eliminate the impact of vibration waves on the protected buildings.
[0008] The current barrier vibration isolation is mainly divided into two categories, namely continuous vibration isolation barriers and non-continuous barriers. The continuous vibration isolation barrier is represented by the vibration isolation trench. When it comes to artificial vibration sources with high vibration frequencies and ground motions, a properly designed vibration isolation trench can achieve good vibration isolation effects. However, for some vibration sources with low vibration frequencies, their wavelengths are generally longer. If an empty trench is selected as a vibration isolation barrier, the empty trench needs to be very deep. This requirement is very difficult to operate in actual construction. If a continuous wall is selected as a vibration isolation barrier, a very large amount of work will be generated, which greatly increases the construction cost, especially when the geological conditions at the construction site are very poor, the construction difficulty and cost will be greatly increased.
[0009] The vibration isolation trench in the prior art is usually a vibration isolation trench of a certain depth, and the vibration isolation trench is only a single-layer vibration isolation trench in the hierarchical structure. Therefore, it can only slightly weaken the vibration wave and cannot produce further vibration isolation effect on the vibration wave, which is very likely to cause certain impacts on the building.
