B, the perfusing hole of mixer and cement asphalt mortar are injected a bag inlet firmly be connected, open the perfusing hole by-pass valve control, cement asphalt mortar injects cement asphalt mortar and injects in the bag, the cement asphalt mortar height reaches more than the 70mm in the perfusing hole of cement asphalt mortar injection bag opposite side, and after closely connected at the bottom of the plate, perfusion finishes;
The perfusion of c, cement asphalt mortar finish reach 0.1MPa through 24 hours and intensity after, in time remove carrying bolt.In order to reach better technique effect, the present invention can also have following feature:
Every block of track plate is poured into by the fill orifice of a side.
The cement injection asphalt mortar, bituminous mortar should carry out under 5～25 ℃ environment temperature.
Cement asphalt mortar if be placed in the surge tank, must keep 10～30 rev/mins mixing speed after mixing and stirring.
In longitudinal gradient and curve area, should be from low side inlet cement injection asphalt mortar, bituminous mortar, and cement asphalt mortar injects bag and be fixed on the footing foundation with the footing foundation contact surface, prevent that cement asphalt mortar from injecting that bag slides or displacement.
Cement asphalt mortar should once pour into and finish under every block of track plate.
After described carrying bolt is removed,, make it be beneficial to draining by designing requirement finishing cement asphalt mortar layer edge.
Paste the section of rubber spacer in track plate bottom, the thickness range of cement asphalt mortar layer is 30～100mm; The thickness range of other section cement asphalt mortar layers at the bottom of the track plate is 40～100mm.
Described track plate or slab track plate, or frame rail plate.
Described carrying bolt is installed on the lifting nut of track plate.
Need to prove: cement asphalt mortar is commonly called the CA mortar on engineering.
The invention has the beneficial effects as follows: can be so that track plate and footing foundation tightly engage, and have and adjust and the buffering effect, make track have certain elasticity simultaneously, thereby can strengthen the application life of track.
