Description

Assembled ballastless track structure for vibration damping location

Technical field

The utility model belongs to non-fragment orbit technical field, more particularly, to the assembled sleeper for vibration damping location Board-like or track platy ballastless track structure.

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 plate-type of I plate-type of CRTS, II plate-type of CRTS and CRTS 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 cast-in-place The reinforced concrete footing with convex block machine on, limited by convex block machine.In unit plate type ballastless track structure, it is laid with peace Be between every piece of track plates after dress it is independent, shortcoming is, line road transport row for a period of time after, track plates and tar sand Starch filled layer can peeling-off, the longitudinal end of track plates is also easy to produce warpage, this undoubtedly can to train operation stationarity, comfortably The service life of property and track structure adversely affects.Although total presently, there are the scheme for being correspondingly improved connection type It is still difficult to meet stress deformation and preparation process challenge between plate body from the point of view of body, and can not overcome at present without the 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 position-limit mechanism that setting is less, limit effect Fruit not can guarantee.
