Description
Technical field
The invention belongs to non-fragment orbit technical field, more particularly, to the prefabricated sleeper for vibration damping location it is board-like or
The wet of the board-like non-fragment orbit of pre-track connects formula assembly method.
Background technique
Non-fragment orbit refers to the track knot for replacing shot ballast bed using mass-type foundations such as concrete, asphalts
Structure.Non-fragment orbit avoids railway ballast splashing, ride comfort is good, and stability is good, long service life, durability compared with Ballast track
Good, maintenance work is few, is applied more and more.Plate-type ballastless track construction relate generally to track plates, asphalt mortar, bituminous mortar or
The structures such as self-compacting concrete filling layer, pedestal or supporting course, wherein pedestal or supporting course use concrete structure, are layed in bottom
Seat or the asphalt mortar, bituminous mortar on supporting course or self-compacting concrete filling layer are the structures of ballastless track structure adjustment and bearing power transmission
Layer.
Currently, China's plate-type ballastless track pattern mainly has III template of I plate-type of CRTS, II plate-type of CRTS and CRTS
Formula non-fragment orbit.I plate-type non-fragment orbit of CRTS is cell board, not vertical between plate and plate to connect, and does not set lateral block, is laid on existing
On the reinforced concrete footing with convex block machine poured, limited by convex block machine.In unit plate type ballastless track structure, it is laid with
Be between every piece of track plates after installation it is independent, shortcoming is, line road transport row for a period of time after, track plates and pitch
Mortar filled layer can be peeling-off, and the longitudinal end of track plates is also easy to produce warpage, this can undoubtedly give the stationarity of train operation, relax
The service life of adaptive and track structure adversely affects.Although presently, there are the scheme for being correspondingly improved connection type,
All in all it is still difficult to meet stress deformation and preparation process challenge between plate body, and current nothing can not be overcome
Tiny fragments of stone, coal, etc. track sketch plate excessively leads to problems such as the assembly of entire non-fragment orbit, maintenance difficult.
It uses longitudinal-connecting type to II plate-type fragment-free track slab of CRTS, and the company of indulging, passes through longitudinal essence between fragment-free track slab and plate
It pricks spiral and tensioning latch fitting forms vertical connection structure, be equipped with lateral block, I plate-type non-fragment orbit of CRTS can be overcome to exist
Segmental defect.Such as tensioning lock for longitudinal connection of ballastless track slab disclosed in patent document 201695285U, by from rail
It is longitudinally connected that the longitudinally projecting reinforcing bar of guidance tape is attached locking realization.But this linked vector graph is essentially identical to longitudinal direction and answers in advance
The mode of power reinforcing bar, connecting structure is complicated, constructs more loaded down with trivial details, and this is rigidly attached to the excessive situation of TEMPERATURE FORCE
Under, there are still the possibility of arch for track plates, this causes the stationarity in service life and train operation to track structure, comfort not
The influence of benefit.
To overcome drawbacks described above, presently, there are the technical solutions that two basic plate longitudinal ends are directly bolted, such as
Patent document CN 201495454U discloses a kind of high-speed railway plate type ballastless track longitudinal connecting structure comprising along route
The track plates being longitudinally laid with, the longitudinal end of track plates are arranged at intervals at least two groups pit and arc-shaped through-hole, arc-shaped through-hole
Both ends are communicated in pit with the longitudinal terminal surface of track plates respectively, are set to pit with the arch screw bolt in arc-shaped through-hole and are connected group
Part is longitudinally connected by adjacent two pieces of track plates.This connection structure, which can overcome, is rigidly attached to the excessive situation lower rail of TEMPERATURE FORCE
The problem of guidance tape arches up, but need to open up the pit of certain depth at plate body both ends in this scheme, then by a groove
On the one hand the bolt hole for opening up perforation connecting pin end additionally opens up pit on plate body and needs to increase process, it is difficult to increase manufacture
Degree and cost, in addition pit therein is in order to meet opening up for bolt hole and being connected and fixed for bolt, inner wall size and shape
With high requirement, so that manufacture difficulty increases；In particular, the setting of this pit causes rainwater, dirt etc. to deposit, and make
It is bolted and is corroded or is difficult to dismount reparation, to increase later maintenance maintenance difficulty.
To overcome drawbacks described above, disclosed in the patent document CN107190584A of applicant's earlier application a kind of for nothing
The assembled position limiting structure of tiny fragments of stone, coal, etc. track, wherein the non-fragment orbit of this assembled position limiting structure of the correspondence disclosed to drawbacks described above into
Targetedly Curve guide impeller is gone.Non-fragment orbit in the technical solution is on the one hand by using the basic plate of multiple various specifications
Flexible configuration and combination are carried out, can need to be assembled into various sizes of cell board according to scene, combining form more diversity, and
And prefabricated basic plate miniaturization, lightness, it is more convenient for manufacturing, stacks transport and assembled in situ, reduce existing Special-shaped Plates
Use；On the other hand it, which is used, is arranged the protrusion and recessed portion to match in the connecting pin of prefabricated basic plate, so as to form
Mortise structure simultaneously carries out fastening using arch screw bolt by the arch screw bolt hole that wherein opens up to anchor basic plate, may be implemented
First several basic plates of assembled non-fragment orbit of Prefabrication, then basic plate is assembled at the scene by certain size by attachment device
Cell board, so as to flexibly arrange in pairs or groups and combine formation length be suitable for scene needs cell board.The non-fragment orbit knot
Structure can make manufacture difficulty therein reduce, and rainwater dirt deposition is not present, and connector corrosion and dismounting difficulty reduce,
Later period repairs easy maintenance.
But the connection of the ballastless track structure each unit plate is realized by the lug boss and recessed portion to match, structure
Still complex, track plates needs are especially prefabricated, and above-mentioned bulge-structure makes protrusion in the middle part of entire raceway surface, in example
Be unsatisfactory for safe escape requirement in such as subway occasion, in addition, between each unit plate of track male-female engagement connection belong to it is mixed
The direct Hard link of concrete board, connection precision is poor, and there is no bufferings between each unit plate, so that whole to entire non-fragment orbit
Body precision is affected；On the other hand, the track plates limiting device of this non-fragment orbit uses special position limiting structure, wherein not
But it is prefabricated to locating part progress, and it will carry out aperture to the basic plate surface connecting with track plates, need specially to base
Plinth plate is designed and is transformed, and not only complex procedures project amount is big, and limit effect is not ideal enough.In particular, this track
Connection structure is arranged between each unit track plates in structure, and position limiting structure is that multiple connectors connect into after certain length again
Setting, i.e., connection structure is individually separated setting with position limiting structure and the two is not corresponded with track plate unit, connects and limits
Position is required to be separately provided and is designed and constructs respectively, and design process is more and project amount is larger, if increase with
The corresponding multiple position limiting structures of connection structure, then prefabricated and improvement project amount is big, if the limit component that setting is less, limit effect
Fruit not can guarantee.
