【Brief description of the drawings】
Fig. 1 is the utility model structural representation,
Fig. 2 is the utility model top view.
【Specific embodiment】
The utility model is described in further detail with implementation method below in conjunction with the accompanying drawings.
Fig. 1 is referred to, the precast slab ballast bed includes square precast slab 1, is formed at the precast concrete
5, two intervals of injected hole at the center of plate 1 are located at the spacing hole of the both sides of the injected hole 5, are symmetrically set in two spacing holes two
The track 6 of side and it is stacked at the cushion blocking 2 of the bottom of the precast slab 1.
The injected hole 5 can irrigate self-compacting concrete in prefabricated board installs application process by it, to realize railway roadbed
The leveling of plate.
The cushion blocking 2 is microvoid polyurethane cushion blocking；The precast slab 1 is taken with microvoid polyurethane cushion blocking
Prefabrication process is compound or the later stage is compound, forms the prefabricated road bed board with effectiveness in vibration suppression.
The width of the precast slab 1 is symmetrically arranged on two with some pre-buried boom hoistings 3；Specifically, described
The quantity of pre-buried boom hoisting 3 is four groups, and every group includes two bolts hole.The boom hoisting is used for the transhipment of prefabricated board,
The jacking in maintenance process is changed in leveling support and railway roadbed that later stage prefabricated board is installed.
The track 6 includes a square protruding and some mounting holes for installing track in the projection,
The track 6 can carry out (1mm is grading) adjustment according to the sweep demand of circuit, can meet various circuit radius need
Ask.
The spacing hole is for square through hole and its inwall covers limiting buffer pad 4, the moulding by casting of the precast slab 1
When default limiting buffer pad 4, can form effective spacing after the casting complete of precast slab 1, it is described spacing at two
Cushion pad 4, plays the horizontal and vertical position-limiting action of road bed board, while providing suitable lateral stiffness.
The inside of the precast slab 1 is located at some reinforcing bars；The track 6 is matched with fastener system, and described is held
Rail platform 6 can manufacture the variable prefabricated board in lateral attitude by die adjustment, to adapt to the demand of route curve change.
The construction method of the utility model precast slab ballast bed, comprises the following steps：
1st, road bed board prefabricated mould prepares, steel reinforcement cage welds colligation, track plate prefabrication and pours
2nd, cushion blocking and road bed board are compound, and cushion blocking and road bed board is (cementing) compound
3rd, the storage of cushion blocking prefabricated board, transport
