Abstract
A railway of double block rail bearings includes a concrete base and a rail bed board fastened to the base. All joints of up and down steel frameworks in the rail bed board are insulated by insulation sleeve. The double block rail bearings are concreted into the rail bed board. Rails are fastened to the double block rail bearings by fasteners and in between the fasteners and the rail bearings has insulation buffering backing plate. The two concrete blocks to the two ends of the rail bearings are connected by steel frameworks, which are made by non-recycle placing of reinforcement and with insulation sleeve inside.
Description
Technical field
The present invention relates to a kind of novel track structure, be applicable to the double-blocked rail without ballast of high-speed railway (comprising Line for Passenger Transportation, passenger-cargo mixed transport line road and railway line for freight traffic), urban track traffic and inter-city rail transit.
Background technology
At present, China railways generally adopts ballasted track.Ballasted track has reached the limit (and railway roadbed is lax gradually) of supporting capacity under long-term high speed, heavy haul train load act on repeatedly, show ballast bed destruction is constantly aggravated, the smooth-going degree variation of track, the maintenance activity amount strengthens, available maintenance time is fewer and feweri, and this has seriously hindered railway and has developed to the direction of high speed, heavy duty.The domestic track structure that also has the examination shop to be close to no circuit maintenance activity, but because of the operating expenses height, speed of application is slow, and substructure in case distortion trimming difficulty etc. also only limits to some special locations.
The overseas high speed railway track structure mainly contains ballasted track and two kinds of basic patterns of ballastless track.Use for reference the experience of state's high speed railway track technical developments such as day, method, moral, the design speed per hour reaches the high-speed railway of 350km, adopts the ballastless track structure to have more superiority than ballasted track.Six kinds of ballastless track upper tracks of moral iron approved are used.In the 660km ballastless track of laying (containing the switch area of group more than 80), Rheda type track accounts for over half, and the Rheda2000 type track of up-to-date exploitation has dropped into commercial the application.
Domestic railway ballastless track research starts from the sixties in last century, and examination was once spread does not have the no tie of quarrel road structure on rest pad formula, short sleeper formula, whole placing formula solid concrete roabed and asphalt cemented ballast bed, the bridge.Since nineteen ninety-five, on portion scientific research project basis, successively lay the elastomeric bearing blocked rail without ballast in Qinling Tunnel; Long sleeper buried-type and plate-type slag-free orbit are laid in test on three grand bridges of Qinhuangdao Shenyang Special Passenger Line: Shahe grand bridge (straight line, long 692m) lays the long sleeper buried-type ballastless track, dog river grand bridge (straight line, long 741m) and stride two what highway grand bridges (curve, long 740m) laying plate-type slag-free orbit; Lay long sleeper buried-type and plate-type slag-free orbit in bosom, Chongqing line, Jiangxi respectively in two tunnels of dragon line.
Summary of the invention
Goal of the invention of the present invention is intended to overcome above-mentioned prior art defective, a kind of brand-new double-blocked rail without ballast structural shape is provided, and this double-blocked rail without ballast is applicable to high speed passenger dedicated railway even can satisfies the novel ballastless track of speed per hour for the operation of 350km/h bullet train.Require enough big track circuit transmission range characteristics of signals requirement at the rail impedance on the track structure of high speed passenger dedicated railway and railway roadbed impedance, provide a kind of under the rainstorm weather situation rail impedance and railway roadbed impedance all can satisfy the track structure of high speed passenger dedicated railway characteristics of signals demand.
Goal of the invention of the present invention realizes by implementing following technical proposals: a kind of double-blocked rail without ballast, it is characterized in that: comprise concrete bed and the road bed board that is fixed on the base, each node of levels steel mesh reinforcement all adopts the insulation sleeve mode to insulate in the road bed board, build the connection double-block type sleeper in the road bed board, rail is fixed on the double-block type sleeper by fastener, between fastener and sleeper, be provided with insulated buffer plate, wherein, double-block type sleeper comprises two concrete blocks that are positioned at the sleeper two ends, connect with steel bar girder between two concrete blocks, adopt no circulation reinforcement manner in the concrete block, be embedded with insulation sleeve in the concrete block.
In the road bed board, be provided with upper and lower layer steel mesh reinforcement, all adopt insulation sleeve to carry out insulated binding at reinforcing bar crossover node place.
The two ends of the steel bar girder of described double-block type sleeper pass two concrete blocks.Make the good integrity of bed board, help loading transfer on the track to ground.
The three-dimensional shape of the steel bar girder of described double-block type sleeper comprises the arbitrary shape that construction work allows.
The steel bar girder of described double-block type sleeper cross sectional shape be triangle, circle, square, trapezoidal or polygonal any one or its combination.
Be provided with reinforcing rib in the hollow of the steel bar girder of described double-block type sleeper, strengthen the intensity of truss.
The steel bar girder bottom layer of the reinforcing steel of described double-block type sleeper can be wrapped in the double-block type sleeper, perhaps exposes out.
The road bed board is established transverse expansion joint at a certain distance, fills with pitch.
At straight line or the less section of superrelation on curve, horizontal open roof is established on bed board surface, road, and in the bigger location of superrelation on curve, one-way slope is established on bed board surface, road.
Distance between the center of two concrete blocks is a standard gauge, is 1435mm.
The invention has the beneficial effects as follows: this double-block type does not have the quarrel sleeper and is applicable to that speed per hour is the 350km/h high speed passenger dedicated railway, be close to no circuit maintenance activity, have high ride, high-durability, high reliability characteristics, so this structure can satisfy the each side technical requirements that China railways develops to high speed, heavily loaded direction, particularly this sleeper reinforcing bar partly exposes, behind final grouting, can very strong adhesion stress be arranged with the railway roadbed board concrete, and the track insulation performance is good, and track structure can satisfy high-speed railway and adopt the requirement of track circuit transmission characteristics of signals; This ballastless track achievement is that China railways reaches the international railway advanced level and has directive function, for solid technical foundation has been established in China's ballastless track technical development.
Ballastless track is more favourable than ballasted track on mixed economy, and the life-span is 60 years.The maintenance cost of ballastless track is that 10% of quarrel is arranged, and this is the most outstanding advantage.The distortion of ballastless track is little, and stability, good endurance have been confirmed the high ride characteristics of track, have reached the purpose of few maintenance, demonstrate good capability and performance.
Generally speaking, double-blocked rail without ballast, science, reasonable, economic, practical has the very high use value of applying.This track technological achievement is that China railways reaches the international railway advanced level and has directive function, for solid technical foundation has been established in China's ballastless track technical development, is called " Chinese double-blocked rail without ballast (TBJZ) " on using.
