Description

Sandwich multilayer assembled vibration isolation trench

Technical Field

The utility model relates to a building shock insulation technical field, in particular to press from both sides core multilayer assembled vibration isolation ditch.

Background

Along with the continuous development and progress of human society, the problems caused by vibration are more and more extensive, the quantity of the vibration generated in production and living of people is increased day by day, the life of people is influenced constantly, and a plurality of buildings with extremely high cultural historical value and great humanistic significance in China are threatened. Particularly, vibration caused by building or road construction and traffic vibration is vibration which is propagated from a vibration source to four places, and is elastic wave radiated to the periphery from the vibration source. The wave propagation method can be divided into three types, namely longitudinal waves (P waves), transverse waves (S waves) (both the longitudinal waves and the transverse waves belong to body waves) and surface waves (L waves).

The damage of the vibration to the building is found in the following three points: 1. the transverse waves cause horizontal swing of the building, so that the building is damaged, and the destructive power is high. The method is equivalent to applying repeated action force in the horizontal direction to a house building, and when the magnitude and the caused deformation exceed the limit of the vibration resistance of a building beam structure, the whole building can be inclined or toppled to cause damage; 2. the longitudinal waves enable the building to bump up and down, and because some buildings are long in age and have poor vertical stability, when the vibration is large, the bottom layer can be used as a pillar of a bearing structure to increase a large dynamic load instantly, the self weight of the upper part is superposed, and when the bearing capacity of the bottom layer pillar is exceeded, the bottom layer pillar can collapse, so that the damage is caused; 3. the buildings are affected by foundation soil disturbance generated by surrounding vibration sources and low-frequency and micro-vibration actions for a long time, and the buildings can generate permanent and irreversible fatigue damage, so that the safety of the buildings is obviously reduced, and various diseases occur.

The vibration isolation measure of the vibration isolation trench is that a vibration isolation barrier is arranged on a propagation path of vibration waves to damage the propagation path of the vibration waves, so that the loss of the energy of the vibration waves is caused, and the purpose of reducing or even eliminating the influence of the vibration waves on a protected building is achieved.

Current barrier vibration isolation is largely divided into two broad categories, namely continuous vibration isolation barriers and discontinuous barriers. The continuous vibration isolation barrier is typically represented by a vibration isolation trench, when an artificial vibration source with higher vibration frequency and earthquake vibration are performed, the properly designed vibration isolation trench can play a good vibration isolation effect, but part of vibration sources with lower vibration frequency have generally longer wavelength, if the hollow trench is selected as the vibration isolation barrier, the hollow trench is required to have great depth, the requirement has great operation difficulty in actual construction, if a continuous wall is selected as the vibration isolation barrier, a very large engineering quantity can be generated, the construction cost is greatly improved, and particularly, when the geological conditions of a construction site are very poor, the construction difficulty and the construction cost can be greatly improved.

The vibration isolation trench in engineering is usually a vibration isolation trench with a certain depth, and the vibration isolation trench has the following defects: the vibration isolation groove is only a vibration isolation groove with a layer of a hierarchical structure, only can initially weaken the vibration waves and cannot perform further vibration isolation effect on the vibration waves, and therefore the influence on surrounding buildings is influenced.
