Background technology
Urban Bridge construction and railway are very easy to the trip of urban population as the urban rapid railway traffic, have improved the mobility that people choose a job at home, are beneficial to the environmental protection in city.But city railway has also brought negative effect such as aspects such as noise, vibration, electromagnetic radiation, views to urban environment, and is wherein outstanding to the influence of environment along the line with noise and vibration.For the city beam build, rail transit noise and vibration isolation aspect, in the design stage, at first should predict the situation of exceeding standard of vibration and noise along the line according to the environmental impact assessment report, implement design scheme then piecemeal.In the circuit working design stage, adopt the vibration and noise reducing measure of economical rationality and technical feasibility, guarantee behind line clear, to obtain the favorable damping noise reduction.And at present, the Vibration Absorption Designing aspect of Urban Bridge structure also exists tangible deficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of and can gives the obviously steel spring floating slab railway roadbed of improvement to existing Urban Bridge, rail transit noise and vibration.
The purpose of this utility model is achieved through the following technical solutions.
The steel spring floating slab railway roadbed comprises: road surface or track, and concrete road bed, steel spring vibration isolator, foundation structure, slipmat and leveling steel plate.The steel spring vibration isolator comprises: metal coil spring, damper and casing.
The steel spring floating slab railway roadbed is between the foundation structure of the concrete road bed and bottom on top, at a certain distance to embed or the arrangement of side is equipped with the steel spring vibration isolator.Be provided with the leveling steel plate between steel spring vibration isolator and the foundation structure, road surface pavement or track on concrete road bed.The steel spring vibration isolator comprises upper and lower casing, is provided with metal coil spring and damper between upper and lower casing.
Steel spring floating slab railway roadbed of the present utility model is as the main vibration reducing measure and the setting of Urban Bridge construction and railway, and its damping element has three dimensional elasticity, and the displacement of horizontal direction is little, and stability is high, need not additional stopping means, and is simple in structure.The fatigue life of steel spring is long, can reach 50 years, and spring is easy to check and change.Utilize this structure can adjust owing to the foundation structure sedimentation height change that causes easily and quickly.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model steel spring floating slab railway roadbed;
Fig. 2 is the structural representation of steel spring vibration isolator.
Among the figure: 1, road surface or track, 2, concrete road bed, 3, the steel spring vibration isolator, 4, foundation structure, 5, slipmat, 6, metal coil spring, 7, damper, 8, casing, 9, the leveling steel plate.
The specific embodiment
With reference to Fig. 1, Fig. 2, the steel spring floating slab railway roadbed, top is concrete road bed 2, concrete road bed 2 top road surface pavement or track 1; The bottom is a foundation structure 4.Concrete road bed 2 and foundation structure 4 between, at a certain distance with embedded or side-mounted arrangement, steel spring vibration isolator 3 is installed.Be provided with leveling steel plate 9 between steel spring vibration isolator 3 and the foundation structure 4.Steel spring vibration isolator 3 comprises upper and lower casing 8, establishes metal coil spring 6 and damper 7 between upper and lower casing 8.When using steel spring vibration isolator 3 in the steel spring floating slab railway roadbed, concrete road bed 2 and steel spring vibration isolator 3 on the skidding 5 of setting up defences between the contact surface of casing; The skidding 5 of between steel spring vibration isolator 3 lower boxes surfaces and the leveling steel plate 9 that is connected, setting up defences; The skidding 5 of between the contact surface of leveling steel plate 9 and it and foundation structure 4, setting up defences.
The job practices of steel spring floating slab railway roadbed: aspect is set up track 1 earlier from top to bottom, reaches acceptance criteria to the height of track 1, level, gauge etc., pours into solid concrete roabed then.The construction of steel spring floating slab railway roadbed should reserve the slit of floating when being in suspended state between plate and runway structure roof when frame rail.Before the cast railway roadbed concrete, should lay isolated film, to isolate railway roadbed concrete and structural concrete.In prefabricated vibration isolator case, place vibration isolator, through to float firm and hard execute jacking after, discharge the jack of jacking, make vibration isolator stressed, rail level rises to design rail level absolute altitude.
The steel spring floating slab railway roadbed is that the concrete road bed board with certain mass and rigidity is floated on the steel spring vibration isolator, constitutes quality-spring-vibrating isolation system.The design principles of plate vibrating isolation system of floating is, excited frequency in the time of should making the structural natural frequencies of the plate of floating avoid the railcar operation, and make the plate rigid body intrinsic frequency of floating, especially vertical intrinsic frequency try one's best far below excited frequency the vibration isolating effect that can obtain.For same excited frequency, the intrinsic frequency of the plate system of floating is low more, and vibration isolating effect is good more.
Metal coil spring is selected quality material for use and is adopted advanced processing technology to be made; Damper is made up of moving component and standing part (damping case), and efficient visous damping agent is housed in the damping case, when moving component moves in damping agent, will produce one opposite with the direction of motion, but the damping force that is directly proportional with the movement velocity size; Casing is welded by steel plate, and it forms a whole spring and damper.
In the steel spring vibration isolator viscous damping is arranged, make steel spring have three dimensional elasticity, and lateral stiffness can independent design, can design very high lateral stability, each that has increased system be to stability and safety, and can suppress and absorb solid-borne sound.
The key step of implementing is as follows:
1, lays barrier film at runway structure end face, with isolation float board concrete and structure end face concrete;
2, frame rail, and adjust track height, level, gauge etc. and reach acceptance criteria;
3, place prefabricated vibration isolator supported box, shuttering, tie up reinforcing bar, place the shearing bar, and the position of adjusting supported box and shearing bar;
4, fluid concrete, reach intensity after, can begin jacking;
5, float after the plate jacking all reaches certain altitude, place vibration isolator and put in place, place leveling steel plate and slipmat;
6, again since an end, unload cushion block and extract cushion block out with jack earlier, fall jack then after rise, the weight of the plate of floating is fallen on the vibration isolator;
7, treat that all plate weight of floating is fallen on the vibration isolator after, the plate of floating is in floating state;
8, measure and the local height of adjusting the plate of floating to design height, the accurate adjustment rail level.
