Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of the cheap of industrial gas oil that be used for, the tangible main equipment low frequency vibration isolation of effectiveness in vibration suppression facility.
For achieving the above object, the utility model is taked following technical scheme: a kind of main equipment low frequency vibration isolation facility, it is characterized in that: it comprises: center on a circle deep trouth that is provided with around the cushion cap ground of main equipment, the bottom of described deep trouth is provided with a circle plain concrete cushion layer; Described plain concrete cushion layer is provided with a vibration isolation medium, and described vibration isolation medium both sides are original soils of compacting; Described cushion cap ground and vibration isolation medium top are provided with concrete ground, around described vibration isolation medium arranged outside one circle asphalt mortar, bituminous mortar isolation strip are arranged in described concrete ground.
Described vibration isolation medium is the several layers extrusion molding benzene plate that cementing agent connects, the fissure of displacement is installed.
Described extrusion molding benzene plate is double-deck extrusion molding benzene plate, and the thickness of the described extrusion molding benzene of each layer plate is 150～250mm.
The height of described extrusion molding benzene plate is 2.5～3.5m.
The height of described extrusion molding benzene plate is 3m.
The wide of described plain concrete cushion layer is 300mm, and height is 50mm.
The utility model is owing to take above technical scheme, it has the following advantages: 1, the utility model is owing to be provided with deep trouth around the cushion cap ground of main equipment, and in deep trouth, be provided with the vibration isolation medium, therefore the vibration wave that sends when main equipment is when the cushion cap basis propagates into the vibration isolation medium, can make vibration wave obtain effective attenuation by the blocking effect of vibration isolation medium.2, the utility model has reduced the setting of large-scale vibration damping equipment, and the ground of vibration isolation deep trouth and main equipment can have been excavated simultaneously owing to do not need to take aboveground space, and it is simple relatively to construct, and cost also greatly reduces.3, the utility model can be determined the height of vibration isolation medium in the vibration isolation facility and the vibration isolation material that is adopted according to the vibration frequency and the needed noise reduction of main equipment, particularly select for use the polyphenyl material as the vibration isolation medium, therefore the propagation that can effectively completely cut off low-frequency noise, workable, effect is obvious.The utility model is cheap, and good stability can be widely used in industrial gas oil factory building and the place that needs to administer vibration noise.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1 and Figure 2, in equipment factory building 1, be placed with main equipment 2, around main equipment 2, be provided with vibration isolation facility 3.
The utility model vibration isolation facility 3 comprises a circle deep trouth 32 that is provided with around the cushion cap ground 31 of main equipment 2 on every side, and the bottom of deep trouth 32 is provided with a circle plain concrete cushion layer 33.Plain concrete cushion layer 33 is provided with a vibration isolation medium 34, and the both sides of vibration isolation medium 34 are original soils 35 of compacting.Cushion cap ground 31 and vibration isolation medium 34 tops are provided with concrete ground 36, in concrete ground 36, one circle slit is arranged around vibration isolation medium 34 arranged outside, filled bitumen mortar in the slit, form a circle asphalt mortar, bituminous mortar isolation strip 37, pitch isolation strip 37 keeps apart concrete ground 36 and concrete ground 4, has reduced the propagation of vibration through concrete ground 4.
In the foregoing description, vibration isolation medium 34 can adopt extrusion molding benzene plate, uses the fissure of displacement to install, and the employing cementing agent is connected between layer and the layer.Vibration isolation medium 34 also can be selected some other materials for use, such as rubber etc., also can reach similar effects.But because the polyphenyl material is cheap, good stability be embedded in underground very difficult generation physics, chemical change, and it is fairly simple to construct, and operability is stronger, therefore selects for use extrusion molding benzene plate as the utility model preferred embodiment.
In the foregoing description, vibration isolation medium 34 adopts double-deck extrusion molding benzene plate, the thickness range 150～250mm of each layer extrusion molding benzene plate.
In the foregoing description, vibration isolation medium 34 height can determine that the altitude range of extrusion molding benzene plate is 2.5～3.5m according to the vibration frequency and the needed noise reduction of main equipment 2.Through compute depth is that the extrusion molding benzene plate of 3.0m can reduce the noise propagated by vibration effectively about 5dB (A), but the application property that has engineering simultaneously.
In the foregoing description, plain concrete cushion layer 33 width are 300mm, highly are 50mm.
Method to set up of the present utility model is:
1) before main equipment 2 is not installed, the cushion cap ground 31 of design in the factory building 1 and the deep trouth 32 around the cushion cap ground 31 to be excavated together, cutting depth is to 31 end of cushion cap ground absolute altitude A.
2) manual amendment deep trouth 32 is to bottom land absolute altitude B.
3) compacting plain concrete cushion layer 33 in the deep trouth between 31 end of cushion cap ground absolute altitude A and 32 end of deep trouth absolute altitude B, concrete cushion 33 width are 300m, highly are 50m.
4) make to make cushion cap ground 31 to the high C of disjunction mark integrally with concrete.
5) fill vibration isolation medium 34 in the deep trouth 32 around the cushion cap ground 31, whole then backfill original soil 35 and compacting be the high C of disjunction mark extremely integrally.
6) integrally making concrete ground 36 above the high C of disjunction mark, and enclose the slit around vibration isolation medium 34 arranged outside one in concrete ground 36, filled bitumen mortar in the slit forms a circle asphalt mortar, bituminous mortar isolation strip 37.
Said method is to utilize vibration wave to run into the propagation medium of sudden change in communication process and the principle that reflects, the vibration wave that sends when main equipment 2 is when Es-region propagations is to vibration isolation medium 34 fundamentally, vibration wave is owing to the sudden change of propagation medium is divided into two parts, most of vibration wave is owing to the sudden change of propagation medium is reflected back, some reflects, the energy of vibration wave has obtained very high attenuation, thereby plays the effect that damped vibration is propagated.
The utility model does not exceed with embodiment, and all equivalent transformations that carries out according to the utility model principle all should not got rid of outside protection domain of the present utility model.
