Description
Technical field
The utility model relates to a kind of orbital maintenance structure, and particularly a kind of plate-type ballastless track maintaining structure belongs to the railroad track field.
Background technology
At present, known high-speed railway plate type ballastless track ballast bed structure forms by three layers, is respectively track plates, CA mortar and base.Track in use is subject to the many factors such as wind, frost, rain, snow, earthquake, flood, Decline or rise of groundwater level, unsuitable distortion will occur in its plane curve and vertical curve, this variation will have a negative impact to the safety of structure after surpassing certain limit, such as, uneven settlement of foundation surpasses 30mm, the adjustment amount that exceeds fastener will have a negative impact to the train of high-speed cruising.Therefore, need to keep in repair the high speed railway track railway roadbed.The method that generally adopts in the industry is to install backing plate additional under fastener, but the adjusting range of backing plate is limited, can not satisfy in some cases the requirement of safe railway operation." ballastless track of high-speed railway line rule (the trying) " that the Ministry of Railways promulgates is with reference to some method for maintaining of Japanese plate-type ballastless track, when track structure occurs greater than the 30mm gap, the main resin material that adopts is repaired gap, but this material price is expensive, and maintenance cost is several times of newly-built expense, and, complicated construction technique, operation easier is also larger, therefore, implements difficulty larger.
The utility model content
A kind of plate-type ballastless track maintaining structure of the utility model discloses new technical scheme, between track plates and CA screed, add packing layer, specifically adopt packed fast solidifying mortar to add the maintenance technique of composite material isolation bed course, solved common maintenance and can not satisfy orbital motion needs and the larger problem of maintenance difficulty.
The utility model plate-type ballastless track maintaining structure comprises rail 1, fastener 2, track plates 3, maintenance packing layer 4, CA screed 5 and lifting body.Rail 1 is fixed on the track plates 3 by fastener 2, maintenance packing layer 4 is arranged on 5 of track plates 3 and CA screeds, lifting body comprises holds power parts 6, secure component 7 and lift-up device 8, hold power parts 6 and be fixedly connected with track plates 3 by secure component 7, lift-up device 8 upwards lifts track plates 3 by holding power parts 6.
The utility model plate-type ballastless track maintaining structure provides a kind of structure of track rapid-maintenance, compares existing scheme on maintenance time, cost and endurance quality, also has on workman's operation task environment all to make progress.
Description of drawings

Fig. 2 is the utility model Embodiment C RTS II plate-type non-fragment orbit maintaining structure schematic diagram.
In Fig. 1～2, the 1st, rail, the 2nd, fastener, the 3rd, track plates, the 4th, the maintenance packing layer, the 5th, CA screed, the 6th, hold the power parts, the 7th, secure component, the 8th, lift-up device, the 9th, chipping filler layer.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As illustrated in fig. 1 and 2, the CRTS I type of the utility model plate-type ballastless track maintaining structure and CRTS II plate-type non-fragment orbit maintaining structure schematic diagram.The plate-type ballastless track maintaining structure comprises rail 1, fastener 2, track plates 3, maintenance packing layer 4, CA screed 5 and lifting body.Rail 1 is fixed on the track plates 3 by fastener 2, and maintenance packing layer 4 is arranged on 5 of track plates 3 and CA screeds.Lifting body comprises holds power parts 6, secure component 7 and lift-up device 8, and holding that power parts 6 can adopt is the T-shape steel, and secure component 7 can be bolt or spiral pin, and lift-up device 8 can be jack.Hold power parts 6 and be fixedly connected with track plates 3 by secure component 7, secure component 7 can adopt internal and external threads to be fastenedly connected with track plates 3, and lift-up device 8 upwards lifts track plates 3 by holding power parts 6.
This programme has been introduced maintenance packing layer 4 and has been adopted lifting body that the structure of maintenance packing layer 4 is set, and has solved only to rely on and has installed the problem that backing plate can not reach maintenance requirement under the fastener additional.
The case back warp that damages at CRTS II plate-type non-fragment orbit 5 breakages of CA screed often occur, falls the phenomenon of piece, find through research, when roadbed generation differential settlement, track plates produces with the CA screed and separates, track plates and rail produced elastic deformation when train passed through, the CA screed is produced the beating compressive stress, thereby cause the generation of above-mentioned infringement.In order to address this problem, this programme arranges chipping filler layer 9 in CA screed 5, and chipping filler layer 9 is filled up the damaged part at CA screed 5, and the material of chipping filler layer 9 can be selected the general special material of the industry.
Rail system is being born heavy transport task, generally only of short duration idle period could occur at the sparse non-peak period of transport power, and this just requires the maintenance work of track to finish within these of short duration time periods.In order to satisfy this harsh requirement, the maintenance packing layer 4 of this programme can comprise the bag of fast hard mortar and the described fast hard mortar of splendid attire, is repairing position putting bag body first, and the fast hard mortar injection that then will stir is in it.The rate of set of fast hard mortar and the key that intensity is problem in this programme, therefore, the fast hard mortar of this programme preferably is comprised of 3 parts of 50 parts of ferrous aluminates, 80 parts of fine sands, 20 parts of mulseals, 14 parts in water and Admixtures, and described Admixture forms by accounting for mass percent 90% polycarboxylate water-reducer and 10% natrium nitrosum.Equally, not fragile in order to guarantee to keep in repair packing layer 4, the preferred nonwoven chemical fabric of the bag of this programme material.In the situation that rush repair, the maintenance packing layer 4 of this programme can also adopt plank, but the material of plank, size and thickness should reach certain standard, and this standard can specifically be determined as the case may be, usually the length of plank is not less than 1000mm, and width is not less than 150mm.
This programme plate-type ballastless track maintaining structure is not limited to the embodiment scope of disclosure, and the alternative that those skilled in the art make in conjunction with common practise according to this programme also belongs to the scope of this programme.
