Description
Technical field
The present invention relates to railway bed repair system and method, particularly high-speed railway subgrade repair system and method.
Background technology
Through high speed railway construction for many years, China has built up worldwide largest High-speed Railway Network.High-speed railway generally adopts plate-type ballastless track, and it is a kind of by a kind of novel track structure that between in-situ cement concrete supporting bed on roadbed, cement emulsified asphalt mortar layer, precast concrete rail plate, plate, connector, rail and fastener etc. partly form.Compare with traditional Ballast track, because non-fragment orbit has been cancelled sleeper and railway roadbed, adopt the direct supporting rail of precast rc slab, thereby have the following advantages: stability, ride comfort are good; Building height is low, from heavy and light, can reduce bridge second phase load and reduce tunnel clearance; Track deformation is slow, good endurance; Maintenance cost is low.
Yet for ensureing train high speed, safety, even running, high ferro requires high to the ride comfort of track.When track irregularity degree exceeds design standard, can greatly reduce ride comfort, when serious, even jeopardize traffic safety.Under the condition of running at high speed, the track irregularity causing due to subgrade settlement also can cause huge wheel-rail force and impact force, can accelerate railway ballast fragmentation, make ballast bed subgrade produce differential settlement, also may cause rail, wheel, axle fracture, cause derailment accident.
And China is vast in territory, complex geologic conditions is changeable, high ferro circuit passes through the junior geologic zones such as weak soil, loess, karst in a large number, and subgrade settlement phenomenon is very general.For the subgrade settlement that may occur, on high ferro non-fragment orbit, preset the steel fastener for adjustable track distortion, when subgrade settlement causes the vertical linear variation of track, can make rail top face return to design elevation by adjusting fastener, but its maximum adjustment amount 15mm only.When subgrade settlement surpasses 15mm, rely on merely the adjusting of fastener to recover track linear just helpless.
In fact, domestic many high ferro line clears are after the operation several years, and sedimentation has appearred in the roadbed of part circuit, causes upper track plated construction to be sunk thereupon, and in order to keep rail level absolute altitude, the means that can only install by unclamping at present backing plate after fastener additional solve temporarily.But for the serious section of some sedimentation (surpassing 10cm), the adjusting range of fastener has reached the limit, still cannot meet the requirement of present situation track level measuring.In light of this situation, in order to ensure traffic safety, speed limit measure is had to take in indivedual sections, has had a strong impact on the riding quality of circuit.
Just under this background, how to solve track plates lifting and make it restore to this problem of present situation track level measuring and become day by day urgent, only have the sinking of fundamentally eliminating track plates, could cancel early speed limit, make high-speed railway along healthy and stable future development.High-speed railway circle has carried out a large amount of research and experiment for this problem.
As Chinese patent application discloses the method for maintaining of a kind of I plate-type non-fragment orbit being disclosed for No. 103132398A, the method comprises: step 1: first utilize jack lifting track plates, to place organic Mortar Plates between track plates and cement asphalt mortar layer, and the organic Mortar Plates periphery between track plates and cement asphalt mortar layer seals by weather strip, between weather strip and organic Mortar Plates, form space; Step 2: inject organic mortar in the weather strip between track plates and cement asphalt mortar layer; Step 3: after organic mortar solidifies, remove weather strip and carry out fastening to track plates.Yet the method for maintaining of this I plate-type non-fragment orbit has following shortcoming and defect: (1), according to the difference of form of structure, high-speed rail plate can be divided into CRTS-I type, II type and III type, between the track plates of some template and bed plate, there is screed to separate, some does not have, for the template that has separation lifting track plates separately, that does not separate cannot realize independent lifting track plates; (2), independent lifting track plates, the screed between padded track plates and bed plate, easily backfill leakiness, produces new gap layer, this can cause adverse effect to the ride comfort of high ferro circuit; (3), directly utilize the independent lifting track plates of jack, do not disclose/suggestion adopts any auxiliary or protective device/measure, and this will force track plates to produce stress deformation, even damaged; (4) how, do not disclose/suggestion applies lifting power to avoid track plates distortion/breakage.
And for example Chinese patent application discloses a kind of non-fragment orbit railway bridge pipeline connector relative settlement adjusting device disclosing for No. 103233400A, comprising: hydraulic lifting device, is embedded in embankment body top along circuit bearing of trend interval; Concrete bearing layer, builds in embankment body top; Track plates, is arranged at concrete bearing layer top; Grouting Pipe, inserts concrete bearing layer bottom along circuit bearing of trend interval.It utilizes the jacking effect of hydraulic lifting device, raise concrete bearing layer and track plates height to meet rail smooth requirement, cement mortar filling and injecting slurry is carried out in the space staying after utilizing Grouting Pipe to the lifting of concrete bearing layer, thereby concrete bearing layer is played to supporting role.Yet this non-fragment orbit railway bridge pipeline connector relative settlement adjusting device has following shortcoming and defect: (1), need permanent bury underground in advance a large amount of hydraulic lifting device and Grouting Pipe, this will significantly increase high ferro construction cost undoubtedly, and the high ferro not also being suitable for after building up is safeguarded simultaneously; (2), lifting only limits to the blank area of bridge and roadbed, scale and the purposes of lifting are less; (3), after high ferro is built up for many years, when needs carry out sedimentation adjustment, cannot guarantee that buried underground hydraulic lifting device and Grouting Pipe all can also normally work, if any one hydraulic lifting device wherein or Grouting Pipe are damaged, the package unit of burying underground all will be scrapped, and this will cause the huge wasting of resources undoubtedly; (4), do not disclose/suggestion adopts any auxiliary or protective device/measure when lifting, and this will force concrete bearing layer to produce stress deformation, even damaged; (5) how, do not disclose/suggestion applies lifting power to avoid the distortion/breakage of concrete bearing layer.
Therefore, provide a kind of existing high-speed railway subgrade sedimentation repair system with actual operation to become urgent problem in the industry.
