Abstract
The utility model discloses a double-block type rail bearing which is especially suitable for being used on high-speed railway ballastless rails. The double-block type rail bearing comprises two concrete blocks which are positioned at both ends of the rail bearing and are provided with smooth surfaces. The two concrete blocks are connected by a steel reinforcement truss. An insulating strip which is fixedly connected with each concrete block is arranged on the surface of each concrete block. The utility model has the characteristics of high smoothness, high durability and high reliability. Therefore, the structure can satisfy all technical requirements of increasing the speed of trains in China. Because a part of the steel reinforcement of the rail bearing is exposed, the steel reinforcement and the concrete of a road bed plate have strong binding power, and the insulating ability of a rail is good after secondary pouring. The rail structure of the utility model can meet the requirements that high-speed railways adopt steel rail communication. The double-block type rail bearing has simple production technique and high popularization and application value, and the utility model is scientific, reasonable, economical and practical. The technological achievement of the utility model has an advising function for railways in China to realize the international railway advanced stage and establishes a solid technology foundation for the technological development of ballastless rails in China.
Description
Technical field
The utility model relates to the high-speed rail technology field, specifically, relates to the double-block type sleeper that is applicable to that the high-speed railway ballastless track uses.
Background technology
At present, China railways generally adopts ballasted track, and ballasted track is lax gradually by railway roadbed repeatedly because of train, smooth-going degree variation, and maintenance activity is big, and needed workload of maintenance and time obstruction railway speed increase development.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 is in case reasons such as distortion trimming difficulty also only limit 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, overall perfusion formula solid concrete roabed and asphalt cemented ballast bed, the bridge.Since nineteen ninety-five, on Ministry of Railways 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) is laid the long sleeper buried-type ballastless track.
Technology contents
Goal of the invention of the present utility model is intended to overcome above-mentioned prior art defective, and a kind of double-block type sleeper brand-new, that be applicable to the use of high-speed railway ballastless track is provided.
Goal of the invention of the present utility model is achieved by the following technical programs: a kind of double-block type sleeper, this 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, be provided with the insulating trip of fixedlying connected on the concrete block surface with it.
Distance between the center of described two concrete blocks is a standard gauge.
The three-dimensional shape of described steel bar girder comprises the arbitrary shape that construction work allows.
The cross sectional shape of steel bar girder be triangle, garden shape, square, trapezoidal or polygonal any one.
Steel bar girder interior has reinforcing rib in the air.
Steel bar girder passes two concrete blocks from horizontal direction, and the lateral surface of two concrete blocks is exposed at its two ends.
Described insulating trip is the ambroin conduit of top seal, and the surface of insulating trip is parallel with the concrete block surface.
The utility model is compared with existing sleeper has following positive effect: 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, intimate no circuit maintenance activity, this structure has high ride, high-durability, high reliability characteristics, so can satisfy the each side technical requirements of China railways speed-raising; Particularly this sleeper reinforcing bar partly exposes, and can very strong adhesion stress be arranged with the railway roadbed board concrete behind final grouting, and makes its track insulation performance good, and track structure can satisfy high-speed railway and adopt the rail communicating requirement.It is simple that double-block type does not have quarrel sleeper production technology, and science, reasonable, economic, practical has the very high use value of applying.This sleeper 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.
