Abstract
The utility model discloses a kind of low structure height precast track plate systems.Including rail, precast track plate, concrete bearing band or concrete buttress and track；Concrete bearing band or concrete buttress has been disposed below in precast track plate, so that precast track plate is limited on waterproof layer by the side constraint of concrete bearing band or concrete buttress；5~10 pairs of tracks are arranged on every piece of precast track plate, each pair of track along rail arranged for interval, the two sides side of precast track plate be equipped with it is horizontal for supporting, the bolt hole of accurate adjustment and lifting.The utility model had both had many advantages, such as that plate-type ballastless track speed of application was fast, later period adjustment is convenient, maintenance workload is few, common shield internal diameter is adapted to again, has the advantages that can adapt to common shield internal diameter small, the track engineering suitable for urban rail transit shield with pre-buried channel flow.
Description
Technical field
The utility model relates to belong to a kind of rail guidance tape system in track engineering field, more particularly, to a kind of low knot
Structure height precast track plate system.
Background technique
Since plate-type ballastless track has, speed of application is fast, appearance is neat and artistic, later period adjustment is convenient, maintenance work
Outstanding advantages of amount is few, in recent years more and more urban track traffics start using plate-type ballastless track.But due to board-like nothing
The road bed board of tiny fragments of stone, coal, etc. track is precast construction, poor to the adaptability of civil construction error.To ensure the smooth of plate-type ballastless track
Implement, usually requires to increase shield internal diameter using the urban track traffic of platy ballastless track structure, lead to the whole of rail traffic
Body cost relative increase is more.
Utility model content
In order to solve the problems, such as background technique, the utility model provides a kind of low structure height precast track plate
System.
The technical solution adopted in the utility model is:
The utility model includes rail, precast track plate, concrete bearing band or concrete buttress and track；Prefabricated rail
Concrete bearing band or concrete buttress has been disposed below in guidance tape, so that precast track plate passes through concrete bearing band or concrete
The side constraint of buttress is limited on waterproof layer；5~10 pairs of tracks are arranged on every piece of precast track plate, each pair of track is along steel
Rail arranged for interval, the two sides side of precast track plate be equipped with it is horizontal for supporting, the bolt hole of accurate adjustment and lifting.
The concrete buttress is mainly by being distributed in precast track plate two sides and along two of rail direction continuous laying
Concrete structure is constituted, and concrete structure is arranged in the bottom surface and side of precast track plate lower part.
The concrete bearing band is mainly by being distributed in precast track plate two sides and mixing along the two rows that rail direction is laid with
Xtah Crude Clay structure is constituted, and every row's concrete structure includes along the spaced apart concrete sub-block in rail direction, concrete sub-block arrangement
In the bottom surface and side of precast track plate lower part.
Every side side of the precast track plate is equipped with two groups of spaced apart bolts hole, and every group of bolt hole includes two
Parallel and near to the bolt hole of arrangement.
The concrete bearing band or concrete buttress are using normal concrete or fast solidifying, early strength concrete.
The rail is mounted on track by fastener.
The fastener is using elastic separated rail fastening.
The utility model is suitable for track engineering of the urban rail transit shield with pre-buried channel flow.
The beneficial effects of the utility model are:
The utility model had both had that plate-type ballastless track speed of application is fast, later period adjustment is convenient, maintenance workload is few
The advantages that, and common shield internal diameter is adapted to, have the advantages that can adapt to common shield internal diameter small, is suitable for city rail and hand over
Logical track engineering of the shield with pre-buried channel flow.

1. rail in figure, 2. fasteners, 3. precast track plates, 4. concrete bearing bands or concrete buttress, 5. tracks, 6.
Bolt hole.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, the utility model specific implementation includes rail 1, precast track plate 3, concrete bearing band or coagulation
Native buttress 4 and track 5；Concrete bearing band or concrete buttress 4 has been disposed below in precast track plate 3, so that pre-track
Plate 3 is limited on waterproof layer by the side constraint of concrete bearing band or concrete buttress 4；Cloth on every piece of precast track plate 3
5~10 pairs of tracks 5 are set, each pair of track 5 is equipped with horizontal use along 1 arranged for interval of rail, the two sides side of precast track plate 3
In the bolt hole 6 of bearing, accurate adjustment and lifting.Rail 1 is mounted on track 5 by fastener 2, and fastener 2 is using elasticity point
Open type fastener.
Precast track plate 3 long 3.5~6m, wide 2.2m, high 0.18~0.2m in specific implementation.
As shown in Fig. 2, concrete buttress is mainly by being distributed in 3 two sides of precast track plate and along 1 direction continuous laying of rail
Two concrete structures constitute, there are space between two concrete structures, concrete structure is arranged under precast track plate 3
The bottom surface and side in portion, so that precast track plate 3 is supported in above waterproof layer.
As shown in figure 3, concrete bearing band is mainly by being distributed in 3 two sides of precast track plate and along the laying of 1 direction of rail
Two rows of concrete structures are constituted, and there are space between two rows of concrete structures, every row's concrete structure includes between 1 direction of rail
Every the concrete sub-block of arrangement, concrete sub-block is arranged in the bottom surface and side of 3 lower part of precast track plate, so that precast track plate
3 are supported in above waterproof layer.
As shown in Figure 1, every side side of precast track plate 3 is equipped with two groups of spaced apart bolts hole, every group of bolt hole packet
Include two bolts hole 3 parallel and near to arrangement.The two sides side of precast track plate 3 be provided with altogether four groups for support, accurate adjustment and
The bolt hole of lifting.
The utility model limits precast track plate particular by using concrete bearing band or concrete buttress
And the effect of drainage channel is formed, it avoids and reinforced concrete footing or self-compacting concrete layer, energy is set after inverted arch backfill
