Abstract
The invention discloses a kind of two groups of long sleeper buried-type crossover turnout railway roadbed casting methods, track switch section route to be poured is divided into branch-cut bridge section (5), lap segment (6), drop-over section (7) and reserved section (8) to both sides from branch-cut bridge, when pouring the railway roadbed of branch-cut bridge section (5), one group of placing installation (9) is respectively configured on two lines road, while being poured since the trouble point of every route to the extending direction of route.It is poured simultaneously using two concrete automobile delivery pumps, completion is poured in 4 hours, it is ensured that track geometry status；Crossover turnout Cha Qu forms four ballastless track beds and pours face parallel construction, and crossover turnout branches off after the completion of the construction of area's railway roadbed, and two working faces is divided to pour double-block type ballastless track lap segment railway roadbed.
Description
Technical field
The invention belongs to high speed railway track Construction Technology fields, and in particular to a kind of long sleeper buried-type high-speed crossover
Track switch trouble area's railway roadbed construction casting method.
Background technique
Track engineering technology is one of high-speed railway core building technology, and long sleeper buried-type high speed is applied without tiny fragments of stone, coal, etc. crossover turnout
Work technology is the construction Difficulties in high-speed railway rail engineering, and high speed mostly uses single group track switch to pour without tiny fragments of stone, coal, etc. crossover turnout at present.But
In long rail accurate adjustment and the static course of receiving, often discovery trouble area's track geometry status it is exceeded can not accurate adjustment, cause Cha Qu without the tiny fragments of stone, coal, etc.
Railway roadbed is done over again, therefore continuous, fast pouring guarantees that track geometry is particularly important to crossover turnout construction error is reduced.Example
The railroad switch construction method as disclosed in Chinese patent CN101215812B, railway roadbed casting method are from one end paragraph by paragraph pouring to another
One end, due to being that each crib pours one by one, it is exceeded to be easy to appear geometry state, needs to be responsible in casting process arrangement special messenger
It is checked, discovery deformation will stop pouring at once and measure inspection and reparation, even if not going wrong, pouring the time also exists
6-8 hours.
The high-speed crossover track switch trouble ballastless track bed side of pouring, area amount is big, fore-and-aft distance is long, it is short to pour the time: pouring total length
275m(wherein branches off section length 155m, both ends non-fragment orbit lap segment 120m), 335 sides measure in the side of pouring, it is desirable that have poured in 4 hours
At.
Summary of the invention
For the prior art, when carrying out track switch railway roadbed and pouring, existing construction efficiency is slow and to be easy to appear geometry state super
Target problem provides a kind of new pouring structure and method.
The technical scheme adopted by the invention is as follows:
A kind of long sleeper buried-type crossover turnout railway roadbed casting method, it is characterised in that: track switch section route to be poured is divided into branch-cut bridge
Section, lap segment, drop-over section and reserved section when pouring branch-cut bridge section, respectively configure one group of placing installation on two lines road, while from every
The trouble point beginning of route is poured to three extending directions of route.
Railway roadbed pours sequence are as follows: branch-cut bridge section-lap segment-reserves section-drop-over section.
Branch-cut bridge section is long sleeper buried-type high speed without tiny fragments of stone, coal, etc. crossover turnout, and lap segment, drop-over section and reserved section are double block type ballastless
Track.
It completes to pour within four hours.
After the completion of lap segment pours, repetition measurement track geometry analyzes shortwave ride comfort.
Repetition measurement is carried out using track geometry status measuring instrument, in the way of being spaced two sleepers and acquiring one group of data, i.e.,
The elevation and plane of the primary left and right rail of every three sleepers repetition measurement carry out shortwave analysis.
Beneficial effects of the present invention: first construct high-speed crossover track switch Cha Qu and trouble before, trouble after non-fragment orbit lap segment railway roadbed,
It constructs after reserving double-block type ballastless track at both ends: being solved with " reserved section double block type ballastless railway roadbed come drop-over branch off area's ballastless track bed "
The area Jue Cha track geometry status it is exceeded can not accurate adjustment the problem of, it is big using concrete automobile delivery pump radius, pour it is flexible excellent
Point solves the total logistics cost problem in long sleeper buried-type high-speed crossover track switch casting process.Utilize two concrete automobile delivery pumps
It is poured before solving two groups of long sleeper buried-type high-speed crossover track switches trouble area's railway roadbeds and trouble simultaneously, double-block type ballastless track long overlap after trouble
Section mass concrete is continuous, the short time interior problem for completing to pour.It has the advantage that
1. ensuring track geometry status: before guaranteeing trouble area's track geometry status and trouble, non-fragment orbit lap segment, reserved section after trouble
The effective drop-over of track geometry status；Completion is poured in 4h, prevents construction lofting accurate adjustment from measuring trouble area section of track track in place
Geometry state is exceeded because of the variation of environment temperature.2. crossover turnout trouble area's railway roadbed reinforcing bar can be effectively ensured in continuous placing railway roadbed
The longitudinal direction of concrete structure and vertical globality, continuity are effectively ensured construction quality and efficiently solve crossover turnout trouble area's railway roadbed
Total logistics cost in concreting process.3. railway roadbed concrete construction tissue is more orderly, railway roadbed concreting is flexible, pours
Speed is built fastly to guarantee continuous placing.
