Description
Technical field
The utility model is related to railroad track technologies, are adjusted more particularly, to a kind of fill-type for railroad track technology
Backing plate.
Background technology
Embedded tracks system is widely applied in urban track traffic, this is because this rail system has
It is easy for installation, and do not need rail clip and fix.CDM is one of embedded tracks system, and advantage is based on a kind of exclusive
Design, i.e. " cladding rail ", rail are completely encapsulated in a kind of prefabricated elastomer, the shape of the intact adaptation track of this elasticity physical efficiency
Shape, and with proper stiffness.After cladding rail is installed to concrete road bed track groove, this system can provide track all
The support in direction, and can reach stringent support requirement in vertical and side, while it can also reduce the influence to environment,
Have the effect of vibration and noise reducing and improve to insulate, reduces the harm of stray electrical current.It is built-in concrete additionally, due to cladding rail
It in the track groove of railway roadbed, need not be fixed using rail clip, track is continuously supported, and is also beneficial to inhibit Rail Surface wave
The generation and development of mill.
In the operational process of rail system, rail head is since wheel-rail friction will produce abrasion, while depression of ground etc. is all
The position of track can be made to change, in order to keep the even running and safety of vehicle, set when the deviation of orbital position reaches
When counting the limit, it is necessary to make adjusting to track.If it is using the fixed track of rail clip system, usually contacting piece system
The parts of system are adjusted, and such as replace or increase railway rail pad.But for embedded tracks, rail is regardless of whether there is packet
Material is covered, can all have solid filling material between track or cladding rail and track slot, therefore track is integrally only hung out into track slot
It can just be adjusted, this mode is time-consuming and sometimes unpractiaca.
Chinese patent CN 200910073186.2 discloses a kind of construction method, which includes the state of track
Adjustment, the injection installation of bag, being stirred of resin material, the injection of resin and post-processing, are stirred with potting resin
Afterwards, by enhancing perfusion to injection bag, being solidified into the insoluble fibre reinforced plastics backing plate not melted, to realize the nothing to track
Grade is turned up.But the patent is not referred to laterally adjusting in orbit adjusting, is not referred to yet and can repeatedly be adjusted to track
When the used method repeatedly filled, this just to be difficult to carry out multiple accurate adjustment in the maintenance to track.
Invention content
The purpose of this utility model be exactly in order to overcome the problems of the above-mentioned prior art and provide it is a kind of it is simple in structure,
It is quick for installation, convenient that the three-dimensional fill-type adjusting backing plate repeatedly adjusted can be achieved.
The purpose of this utility model can be achieved through the following technical solutions：
The utility model devises a kind of fill-type that achievable solid is repeatedly adjusted and adjusts backing plate, the backing plate with it is embedded
The clad of cladding rail is installed along in track and track groove.Backing plate includes that filling injection bag and side adjust filler material two
Part is separately positioned on the outer bottom and lateral surface of the clad of embedded cladding rail.It is injected in filling and injects filling in bag
Material adjusts filler material thickness to adjust the position of embedded cladding rail by the injection rate and side that control filler.
Further, filling injection bag is the single or multiple forms stacked, and injection is equipped in one end of filling injection bag
End, the other end, which is equipped with, emits outlet, the injection end and emits outlet bottom and is fixed on filling injection bag that (position is in filling and notes
Enter the middle part of bag), and above the clad that the lateral surface of the clad extends to.
Further, multiple fillings stacked, which inject the injection end of bags and emit outlet, is arranged in order, it is not possible to the shape stacked
Formula arranges.
Further, the injection end of filling injection bag is pipe shape with outlet is emitted, and length is more than embedded cladding steel
The height of rail, width are more than 5mm.Since embedded cladding rail is to be fixed on-railway roadbed track by way of concreting
Including slot, when the length of filling injection bag is more than 2m, then needs to increase injection end and emit the quantity of outlet；In injection end and emerge
It holds and places spacer bar in hose, to ensure to have enough mortar Injection Spaces, the length of the spacer bar and embedded cladding rail
Highly consistent, thickness 5-10mm, material is rubber, metal or composite material.Before starting injection filling mortar, interval should be taken out
Item.
Further, filling injection bag fabric is nylon composite polyethylene material, and one layer of reinforcing core material is arranged in inside,
Nylon composite polyethylene material heat resisting temperature is more than 110 DEG C, and tensile strength is more than 10MPa, and inside strengthens core material and uses glass fibers
Tie up cloth material or with material more than same performance.
Further, filling injection bag direction along ng a path arrangement, to ensure the precision of orbital position adjusting, length limit
It is made as 1-10m, the outer bottom of width and the clad of embedded cladding rail is same wide.
Further, in construction, filling injection bag is fixed by the way of binder, thin-film material package or binding strap
On embedded cladding rail, or at the construction field (site) or installation is fixed in embedded cladding rail production site.It is filled out
When filling, the filler injected in filling injection bag is CA mortars or resin material.
While embedded rail foot placement fill-type adjusts backing plate, side adjusts filler material and is filled in embedded packet
It covers between the lateral surface of rail clad and railway roadbed track groove, the lateral position of rail is adjusted with this.Side adjusts filler material
Material be hydroelasticity material, solidification after with it is embedded cladding rail clad physical characteristic similar in, can be with steel
It combines closely between rail clad and railway roadbed track groove.In addition, the bottom end that side adjusts filler material is provided with reserved cavity, to prevent
It is only cut to during construction concrete road bed.
Compared with prior art, rail need not be hung out when the utility model is adjusted, can be laterally adjusted and is repeatedly adjusted
Section will not adjust backing plate to fill-type and have an impact when replacing new-track.
The utility model is solving the problems, such as that embedded tracks are difficult to be adjusted.By being placed in advance outside cladding rail
The mortar filling bag of the multilayer fill-type backing plate of bottom surface and the adjusting filler material of side reach the purpose of adjustable track position.Work as rail
Road in operation abrasion the subsidence of foundations or it is other due to deviate initially set position when, it is necessary to by track adjusting arrive
Preset position, to ensure road-ability and safety.Using the utility model, preset mortar filling bag is given to inject sand first
The vertical position of adjustable track is starched, lateral position is further adjusted to reach accurate adjusting by the adjusting filler material of side.
Multilayer injects the design of bag, may be implemented repeatedly to be adjusted during the projected life of track, has simple in structure, installation soon
Feature prompt, easy to adjust.
