Embodiment 1
[0042] Example 1, a CRTS III type slab ballastless track self-compacting concrete pouring tool.
[0043] Such as figure 1 As shown, the CRTSⅢ plate type ballastless track self-compacting concrete pouring tool provided by the present invention includes a track plate 11, a base plate 12, a transfer bucket 2, a pouring funnel 7, a slurry retaining formwork 8, a three-dimensional fine adjuster 9, and a track plate press. Tightening device 10, track slab anti-skid device and slurry retaining formwork compacting device.
[0044] The base plate 12 is positioned at the lowermost floor, and it is reserved with two steel bars 10-5 (see image 3 ), and the two reserved steel bars 10-5 protrude from the two opposite outer sides of the base plate 12 respectively. The track plate 11 is laid on the top of the base plate 12 with a certain distance therebetween.
[0045] The transfer bucket 2 is a hollow cavity with upper and lower openings and a large top and a small bottom. The top of the...
Embodiment 2
[0056] Embodiment 2, a method for pouring self-compacting concrete for CRTS III slab ballastless track.
[0057] refer to Figure 1~Figure 3 , the method specifically includes the following steps:
[0058] Step a. Install the three-dimensional fine adjuster 9 on both sides of the track plate 11, and adjust the height, center line and front and rear position of the track plate 11 through the three-dimensional fine adjuster 9 to meet the preset requirements.
[0059] Before this step, the manufacture of the base plate 12 and the laying of the track plate 11 have been completed. When the base plate 12 is manufactured, two steel bars 10-5 are reserved inside, and the reserved two steel bars 10-5 protrude from the two opposite outer surfaces of the base plate 12 respectively. The track plate 11 is laid on the base plate 12 with a predetermined distance between them.
[0060] In this step, the three-dimensional fine adjuster 9 includes an elevation adjustment screw 9-1 and a hori...

Abstract
The invention provides a CRTS III type slab ballastless track self-compacting concrete casting tooling and method. The casting tooling comprises a base slab, a track slab, a transferring hopper, a casting funnel, a slurry blocking template, a three-dimensional fine regulator, a track slab pressing device, a track slab lateral sliding preventing device and a slurry blocking template pressing device. The middle casting mode is changed into the lateral surface casting, and the problems of casting efficiency and air exhaust in the CRTS III type slab ballastless track construction are solved. The track slab lateral sliding preventing device, the track slab pressing device and the slurry blocking template pressing device effectively solve the problems of upward floating, lateral sliding and slurry leakage of the track slab in the casting process, so the fine regulation and the casting construction of the CRTS III type slab ballastless track are more convenient and fast, and the casting quality is better. The construction process has the advantages that in the use process, the weight is light, the rigidity is high, the efficiency is high, the operation is simple and convenient, the work intensity is low, and the construction process can adapt to the construction of road segments such as bridges, tunnels and roadbeds.
Description
technical field [0001] The invention relates to a self-compacting concrete pouring method under a slab, in particular to a self-compacting concrete pouring tool and method for a CRTS III slab ballastless track. Background technique [0002] The CRTSⅢ slab ballastless track is a ballastless track with completely independent intellectual property rights developed and proposed on the basis of summarizing the research and application experience of my country's existing ballastless track. The main features of the CRTSⅢ slab ballastless track are: the filling layer material under the slab is changed to self-compacting concrete, and the original CA mortar used in the original Ⅰ and Ⅱ slab ballastless track is cancelled. [0003] The filling layer under the slab is located between the track slab and the base. It is an important structural component of the CRTSⅢ slab ballastless track, and plays a key role in connecting the upper and lower and transmitting the longitudinal, transvers...
