Description
Technical field
The invention belongs to building vibration isolation technique field, it relates to a kind of be arranged on the vibration isolation ditch below road.
Background technology
Vibration isolation ditch is a kind of common engineering method, in order to hinder or to change peripheral wave of oscillation to the propagation by shadow zone, thus reduces the ground vibration of shadow zone. The principle of vibration isolation ditch is based upon on the reflection of ripple, the basis of scattering. When the ripple in propagating runs into the separation surface of two kinds of different elastic mediums, part incident wave is reflected back the first medium, and another part wave loops is to, in the 2nd kind of medium, this is exactly reflection and the transmission phenomenon of elastic wave. Vibration isolation ditch can also change the frequency distribution of ripple, the energy of the dispersion main frequency range of ripple, is conducive to reducing the vibration effect of vibration. Owing to wave of oscillation is when underground runs into different media, between medium, difference is more big, and vibrometer ground roll more easily reflects and not easily passes dielectric interface. For stoping the propagation of surface-duided wave, it is possible to take the measure cutting off vibration route of transmission, namely take ditching form on stratum. It is empty in the vibration isolation ditch ditch of common buildings, i.e. not packing material, then cover plate is set at vibration isolation ditch top, such as the CN203531169U patent of Patent Office of the People's Republic of China's bulletin on April 9th, 2014, name is called that, from displacement every shake trench system, the ditch body inside of this structure of vibration isolation ditch is empty, above establishes cover plate, the heavy ability of cover plate, therefore the vibration isolation ditch of this structure can not be arranged on below road.
Summary of the invention
It is an object of the invention to solve vibration isolation ditch empty in tradition cannot load-bearing, problem below road cannot be arranged on, it is provided that a kind of vibration isolation ditch band below road being set and filling.

Vibration isolation water tank utilizes the wave of oscillation of the absorption of vibrations transmission of water body, eliminates wave of oscillation energy, damping vibration wave loops. Back and forth through the vibration damping hole on dividing plate when shaking about water body, utilize vibration damping hole that the retardance of water body is cut down rapidly vibration energy.
As preferably, the bottom of described vibration isolation water tank is placed on the bottom of ditch body, and vibration isolation tank top is no more than sandstone packing layer end face.
As there being choosing, described dividing plate is dull and stereotyped.
As other preferred, described dividing plate is waviness plate along ditch body direction, and two ends and the water tank sidewall of dividing plate are welded and fixed, can be freely movable between the upper and lower side of dividing plate and water tank wall. It is ripple struction between dividing plate two inboardend, and upper and lower sides is free side, it is possible to make dividing plate itself can absorb certain vibration energy, reduces the intensity of wave of oscillation.
As preferably, parallel in described vibration isolation water tank arranging multilayer insulating panel, the vibration damping hole site of adjacent separator shifts to install. The concussion position of water body between two dividing plate vibration damping holes interlocks, and forms complicated shearing action, can absorbing vibrational energy more effectively.
As preferably, described vibration isolation tank box top is provided with water-in, and water-in is connected with rainwater on road surface mouth. Rainwater is utilized to supplement the water in vibration isolation water tank.
As preferably, described vibration isolation water tank is along ditch body bearing of trend subsection setup. Vibration isolation water tank can be arranged in split, reduces difficulty of processing.
Vibration isolation ditch of the present invention adopts sandstone to fill, and makes vibration isolation ditch have weight capacity, it is possible to be arranged on below road; Sandstone packing layer arranges vibration isolation water tank, it is possible to effectively absorb the wave of oscillation of transmission, reduce the transmission of vibration isolation ditch both sides wave of oscillation further.
