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: the transverse wave causes the horizontal swing of the building, which causes the damage of the building and has great destructive power. 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; the longitudinal wave makes the building produce jolt from top to bottom, because some buildings are long in the past, its vertical stability is relatively poor, when the vibration is great, can make the bottom increase very big dynamic load as load-carrying members' post in the twinkling of an eye, the dead weight on stack upper portion, when surpassing bottom post bearing capacity, thereby the bottom post can collapse and lead to destroying. 3. The building is affected by foundation soil disturbance generated by surrounding vibration sources and low-frequency and micro-vibration actions for a long time, and the building can generate permanent and irreversible fatigue damage, so that the safety of the building is obviously reduced, and various hidden dangers appear.

The common vibration isolation ditch comprises a filled vibration isolation ditch and a vibration isolation empty ditch, and related vibration isolation researchers indicate that the vibration isolation effect of the vibration isolation empty ditch is superior to that of the filled vibration isolation ditch and is the most effective path vibration isolation method, but the vibration isolation empty ditch has the defects of difficult structural support, difficult later maintenance and easy water seepage. Therefore, the method for reducing the influence of the surrounding vibration on the building through the vibration isolation empty trench has important economic significance and environmental protection significance. The invention aims to design a vibration isolation empty trench which is convenient and reliable in supporting structure, waterproof, seepage-proof and easy to maintain.
