Technical field:
The present invention relates to one have the tiny fragments of stone, coal, etc. floating vibration-damping ballast monomer and have the floating vibration-damping ballast of the tiny fragments of stone, coal, etc.
Background technology:
Rubble railway ballast has plurality of advantages in guarantee train traffic safety, thus still mainly adopts ballast bed at city underground rolling stock section this kind of track switch close quarters.At present, metro depot periphery soil and space are in be continually developed and actively uses, and self damping capacity ballast bed can not meet actual demand far away.In order to reduce the noise pollution that vibration produces, if directly adopt flexible anti-vibration fastener can produce larger derail potential safety hazard at track switch place on ballast bed, and for the more existing solid concrete roabed with better vibration isolation capability, they are higher to the fundamental importance of railway roadbed, are unsuitable for earth's surface weak soil.Therefore, be how the railway roadbed that the metro depot region that track switch is intensive provides a kind of anti-vibration performance excellent, make it can ensure the travel safety of train, ambient vibration can be suppressed again well just to become current study hotspot in the industry and emphasis.
Summary of the invention:
The invention provides one have the tiny fragments of stone, coal, etc. floating vibration-damping ballast monomer and have the floating vibration-damping ballast of the tiny fragments of stone, coal, etc., its reasonable in design, improves anti-vibration performance, decreases the noise pollution that vibration produces, solves problems of the prior art.
Of the present invention have the tiny fragments of stone, coal, etc. floating vibration-damping ballast monomer for solving the problems of the technologies described above adopted technical scheme to be: it comprises railway ballast basket, rubble railway ballast layer is provided with in railway ballast basket, be provided with base plate in railway ballast basket bottom, between railway ballast basket and base plate, be provided with the first isolation mounting.
Described first isolation mounting is the first vibration isolator.
The second isolation mounting is provided with between rubble railway ballast layer and railway ballast basket.
Described second isolation mounting comprises the enhancing pad being located at upper strata and the second vibration isolator being located at lower floor.
Described enhancing pad is made into integration with the second vibration isolator.
Described railway ballast basket is linear or herringbone or X-shaped.
Of the present invention have the floating vibration-damping ballast of the tiny fragments of stone, coal, etc. for solving the problems of the technologies described above adopted technical scheme to be: it comprise some sections of being arranged on continuously successively in the groove of railway roadbed basis end to end have the floating vibration-damping ballast monomer of the tiny fragments of stone, coal, etc., adjacent two are had between two railway ballast baskets in the floating vibration-damping ballast monomer of the tiny fragments of stone, coal, etc. and are connected by shear hinge.
Adjacent two have between two base plates in the floating vibration-damping ballast monomer of the tiny fragments of stone, coal, etc. by shear hinge be connected.
The second isolation mounting is provided with between the rubble railway ballast layer having the floating vibration-damping ballast monomer of the tiny fragments of stone, coal, etc. and railway ballast basket.
Described second isolation mounting comprises the enhancing pad being located at upper strata and the second vibration isolator being located at lower floor.
The present invention adopts such scheme, there are following three advantages: 1, for former ballast bed, each instantaneous railway roadbed basic stress only having less area, pressure is larger, namely each instantaneously only has minority rubble bearing and transmitting wheel weight, and railway ballast basket of the present invention can increase the lifting surface area on railway roadbed basis, improve the stressing conditions of the metro environment vibration belonging to Near-field Problems In Civil Engineering; 2, the rubble in railway ballast basket can be similar to as a whole participation energy-absorbing, and this is existing ballast bedly cannot to realize; 3, the present invention is generally laid on earth's surface, also can form mass-spring system between the soft soil in top layer and base plate, thus present invention achieves a kind of multistage vibrating isolation system.Therefore, ballast bed compared to existing, the present invention has better anti-vibration performance, reduces the noise pollution that vibration produces.
