Ring；The normal use of precision instrument is impacted；Building inherently safe is impacted.Vibration reducing measure is broadly divided at present
Three classes：Vibration source vibration damping, path vibration isolation, building passive vibration isolation.Vibration source vibration damping takes measures on train and track, by train
Operation causes vibration to reduce；Path vibration isolation is to arrange vibration isolation measure on the path of Vibration propagation, prevents the propagation of vibration wave；Build
Build thing passive vibration isolation to isolate sensitive target with corresponding isolation mounting, to reduce the interference of vibration.Path vibration isolation is on ground
Ferrum vibration damping field plays a significant role, in particular for the existing building vibration exceeding the standard problem around existing subway line, road
Footpath vibration isolation almost becomes primary selection.
Vibration isolation Vibration Isolation by Piles in Rows is a kind of important component part of path vibration isolation, and common vibration isolation campshed adopts a row or multi-row
Concrete-pile is arranged between vibration source and sensitivity building, to reach vibration isolating effect.Existing common vibration isolation campshed be primarily present with
Lower several respects shortcoming：
(1) horizontal layout in stake footpath, pilespacing and campshed of traditional shock-isolating pile made of fine etc. does not have to calculate the vibration isolation bandgap frequency of itself,
Random arrangement, causes traditional Vibration Isolation by Piles in Rows DeGrain, and difficult up to expection, cost performance is relatively low；
(2) traditional shock-isolating pile made of fine is designed without considering the characteristic frequency of Subway Vibration vibration source, it is impossible to special according to the frequency of vibration source
Property carries out the design of vibration isolation campshed, causes to give full play to the vibration isolating effect of measure.
Utility model content
For weak point present in the problems referred to above, this utility model provides a kind of periodicity vibration isolation campshed, alleviates ground
Ferrum train operation causes Adjacent Buildings to vibrate excessive or even exceeded problem, solves traditional vibration isolation campshed and designs unreasonable, difficult
To reach the problem of expected vibration isolation target.
For achieving the above object, this utility model provides a kind of periodicity vibration isolation campshed, including at least three row vibration isolation campsheds,
Often arrange vibration isolation campshed and be all disposed with multiple shock-isolating pile made of fine, all shock-isolating pile made of fine are arranged according to the quincuncial pile form of equilateral triangle.
Further improve as this utility model, when vibration source is underground vibration source, the depth of the shock-isolating pile made of fine is not less than vibration source
Depth.
Further improve as this utility model, the span of the shock-isolating pile made of fine is than f=r/a, wherein, r for shock-isolating pile made of fine half
