Description
Technical field
The utility model belongs to the vibration of rail traffic and field of noise control more particularly to one kind change in which can be convenient
The slab track ballast bed structure of vibration damping grade.
Background technique
In recent years, with the rapid development of China's rail traffic, rail traffic has gradually entered into our life.Track is handed over
Lead to while providing quick, safe trip to us, the vibration and noise problem generated is also serious to affect periphery
The quality of life of resident jeopardizes the safety of neighboring buildings, meanwhile, to the stability of rail traffic itself, safety and use the longevity
Life etc. also brings many adverse effects.Therefore, try to reduce track vibration and noise, improve the association of itself and nature and living environment
Tune relationship, become rail traffic can sustainable development key.It is found in practice, due to complex geologic conditions, Planning changes etc.
The case where reason causes the original vibration control measure of rail traffic to be unable to reach expected environmental impact assessment target happens occasionally, but existing each
Mounting condition, the outer dimension of kind railway roadbed damped products etc. are widely different, can not subtract conveniently by replacement damped products realization
Vibration means upgrade, and cannot change vibration damping rank as needed between the ballast bed structure of various difference vibration damping ranks, build again not
Only cost is huge, and construction period is very long, seriously affects operation, because these difficult presence, often result in and disturb residents
The case where cannot slowly being solved after problem, therefore caused many environmental protection and complained.
In addition, existing ballast bed of track, which generallys use, first pours substrate, then pours track plates or put prefabricated track again
The form of construction work of plate, on the one hand, in tunnel, under the conditions of working spaces are restricted on bridge etc., need repeatedly to transport stage by stage
Defeated various building materials, construction speed are slower；On the other hand, construction precision is influenced by live operator profile, construction quality
It is not easy to ensure, the exceeded phenomenon of construction error happens occasionally.
Utility model content
