Specific embodiment
The utility model feature and other correlated characteristics are described in further detail by embodiment below in conjunction with accompanying drawing,
In order to the understanding of technical staff of the same trade：
As Figure 1-4,1-15 is marked to be expressed as in figure：Precast track plate 1, track 2, self-compacting concrete layer
3rd, intermediate isolating layer 4, substrate 5, limited impression 6, elastic insert 7, gate reinforcing bar 8, lateral ditch 9, exhaust and peep hole 10, filling
Orifice 11, drainage terminal 12, lifting sleeve pipe 13, reinforced mesh 14, expansion joint 15.
Embodiment：As shown in figure 1, urban track traffic Prefabricated slab type track includes the He of precast track plate 1 in the present embodiment
Substrate 5, precast track plate 1 is erected on substrate 5.Track 2, track 2 are fixedly installed on the surface of precast track plate 1
It is non-shoulder track, its rail support groove non-shoulder for being used to constrain rail fastening is more suitable for the fastener of railway traffic engineering.
As shown in figure 1, be provided between precast track plate 1 and substrate 5 self-compacting concrete layer 3, precast track plate 1 with
Self-compacting concrete layer 3 pours integral.As shown in Fig. 2 offered on precast track plate 1 fill orifice 11 and positioned at its two
The exhaust of side and peep hole 10, wherein fill orifice 11 are used for the perfusion of self-compacting concrete layer 3, and are vented and the side of peep hole 10 1
Face is used to discharge the air between precast track plate 1 and substrate 5, it is to avoid air is caused in remaining in self-compacting concrete layer 3
Defect, on the other hand pours situation, it is to avoid concreting amount is not enough for observing self-compacting concrete layer 3.
