Problems solved by technology

[0003] The purpose of the present invention is to provide a method for manufacturing turnout plates for slab-type ballastless track, which solves the problems that the surface of the turnout plate and the turnout between the bearing platforms of traditional ballastless turnout plates are poorly matched, and the size of the transverse bearing platform does not meet the needs of high-speed rails. , and also solve the problems of poor accuracy of traditional concrete track slab dimensions, poor smoothness, heavy maintenance workload, slow construction speed, poor integrity, poor safety, and inability to adapt to the production of fixed pedestals

Embodiment Construction

[0040] Such as figure 1 , figure 2 , image 3 As shown, the slab type ballastless track turnout plate system includes No. 18 crossing line turnout plate, No. 18 opening line turnout plate, No. 50 turnout plate, and No. 42 turnout plate. A slab type ballastless track turnout slab, the slab body 1 is a reinforced concrete structure, the edge of the slab body 1 has pre-embedded ribs 6 and pre-embedded hoisting parts 7, and the concrete is covered with a reinforcement mesh 5, the warp and weft of the reinforcement mesh 5 The intersections of steel bars are bound and connected by insulating cable ties 8. The thickness of the board body 1 is 240 mm, and a horizontal rail bearing platform 2 with a width of 300 mm and a longitudinal spacing of 600 mm is arranged on it. The surface of the rail bearing platform 2 is horizontal; The surface of the turnout plate is provided with 0.5% lateral drainage slope and transverse pre-crack 3 with a depth of 40mm, and there are positioning holes...

Abstract

The invention provides a plate type ballastless track turnout plate and a manufacture method thereof. The method comprise the steps of: providing a model for manufacturing the plate type ballastless track turnout plate; accurately measuring a track bearing plane of a template; blanking reinforcing steel bar for the model; assembling a reinforcement fabric sheet on a reinforcing steel bar bound jig frame and hoisting the jig frame assembled with the reinforcement fabric sheet into the model; arranging embedded bars inside the model; pouring concrete for the model; carrying out steam curing on the plate type ballastless track turnout plate; accurately drilling the plate type ballastless track turnout plate; arranging fasteners on the plate type ballastless track turnout plate; and storing a finished product of the plate type ballastless track turnout plate. The plate type ballastless track turnout plate is integrated with the characteristics of high stability, low maintenance work load and good plate type integrity of a ballastless track, has outstanding dimensional accuracy and high smoothness, and benefits the reduction of impact force and friction force generated during the running of railway lines for passenger traffic and the improvement of the running stability of a train.

Description

technical field [0001] The invention relates to a concrete track slab of a passenger dedicated line and a manufacturing method thereof. Background technique [0002] Due to the various types and complex shapes of turnout slabs required for passenger dedicated lines, the traditional concrete track slabs and their manufacturing methods have defects such as poor accuracy of dimensions, heavy maintenance workload, and poor integrity, which cannot meet the needs of passenger dedicated lines and urban rail transit. The high ride comfort of the passenger-dedicated line cannot be guaranteed, and the impact and friction of the passenger-dedicated trains during operation are relatively large, which affects the stability of the train operation. Contents of the invention [0003] The purpose of the present invention is to provide a method for manufacturing turnout plates for slab-type ballastless track, which solves the problems that the surface of the turnout plate and the turnout be...
