Problems solved by technology

Because China’s railway signal transmission is carried out through steel rails, the rails are installed on the track slab, and the track slab is laid on the line, the electromagnetic induction generated by the steel mesh inside the track slab will have a greater impact on the rail transmission signal, resulting in shortened signal transmission distance and increased costs. Therefore, in order not to affect the signal transmission of the rails, the steel mesh inside the track slab must have good insulation properties

Embodiment 1

[0011] like figure 1 As shown in the figure, a method for insulating tie-up of reinforcing mesh of track slab is used to bind longitudinal reinforcing bar 2 and horizontal reinforcing bar 3 nodes of reinforcing mesh inside the track slab with insulating binding wire 1, and there is insulation between the longitudinal reinforcing bar 2 and horizontal reinforcing bar 3 nodes. Pad 4, insulation binding wire 1 is a plastic binding wire.

Embodiment 2

[0013] like figure 1 As shown in the figure, a method for insulating tie-up of reinforcing mesh of track slab is used to bind longitudinal reinforcing bar 2 and horizontal reinforcing bar 3 nodes of reinforcing mesh inside the track slab with insulating binding wire 1, and there is insulation between the longitudinal reinforcing bar 2 and horizontal reinforcing bar 3 nodes. Pad 4, insulating binding wire 1 is epoxy resin insulating coated iron wire.

Abstract

The invention discloses an insulating strapping of the track plate bar mat. It binds the longitudinal and the cross direction bar using the insulating binding line. The insulating pad is set between the nodes of the bar. The bar net bond by the method has the good insulating property, so it meets the demand of the track circuit technology.

Description

technical field [0001] The invention relates to a steel bar binding method, in particular to a built-in steel bar binding method for laying a track slab of a ballastless track. Background technique [0002] With the development of society, high-speed railway transportation has become the common goal pursued by all countries in the world. In order to meet the requirements of high stability, high durability and comfort of high-speed railways, it is necessary to adopt and develop ballastless tracks with less maintenance. Since the signal transmission of China Railway is carried out through the steel rail, the steel rail is installed on the track slab, and the track slab is laid on the line. The electromagnetic induction generated by the steel mesh inside the track slab will have a greater impact on the rail transmission signal, resulting in shortened signal transmission distance and increased cost. Therefore, in order not to affect the signal transmission of the rail, the stee...
