The track of the high-speed railway is basically in a ballastless track form, and the development process of a CRTS I slab ballastless track, a CRTS II slab ballastless track and a CRTS III slab ballastless track is experienced from the first high-speed railway to the present, wherein the CRTS I slab ballastless track and the CRTS II slab ballastless track both adopt cement emulsified asphalt mortar adjusting layers, the CRTS III slab ballastless track is a high-speed railway track type self-compacting concrete adjusting layer adopting reinforcing bars, which is a completely independent knowledge product in China, and the track is greatly popularized and applied in the high-speed railway construction.

The CRTS III type plate ballastless track plate has good fluidity and obvious liquid characteristic when being poured due to the self-compacting concrete pouring, and has certain buoyancy according to the Archimedes' law, so that the buoyancy on the ballastless track plate in the self-compacting concrete pouring process needs to be offset by a withholding technology. In the prior art, a 14# channel steel welded steel plate is generally adopted as a cross beam, an M22 multiplied by 650 screw rod is adopted as a tension rod and fixed on the side surface of a base plate (pre-buried or directly drilled), and each track plate uses 5 pressing devices. Meanwhile, 4 dial indicators are required to be arranged at four corners of the track slab of the straight-line segment, a floating and sinking change value is measured, 2 dial indicators are arranged at the lower end of the curve segment, a lateral movement value is measured, and floating and lateral movement are required to be not more than 2 mm.

In the actual construction process, people often monitor each dial indicator, the filling process is guided, the recording is usually carried out before filling, the recording is carried out after filling is finished, at the moment, if the upper limit is exceeded, the recording cannot be made up, and only the lifting plate can be used for refilling, so that the waste of manpower and material resources can be caused.

In addition, in the process of pouring the self-compacting concrete, the self-compacting concrete is easy to fill the gap between the track slab and the base slab, namely, a cavity defect is generated; or obvious bubbles or slag inclusion exists, namely the self-compacting concrete is not compact; the self-compacting concrete and the track slab or the base slab are not closely attached, and gaps exist, namely, the gap defect is generated; in addition, the appearance of the self-compacting concrete is isolated, and the quality defects of exposed stones, exposed ribs, honeycomb gaps, sunken seams, large bubble accumulation areas, foam layers and the like can occur. These hidden quality defects are gradually exposed to diseases after operation, resulting in unevenness of the track or cracking of the track portion, which will cause operational risks, and the cost of repair is huge.
