Description
Technical field
It is obstructed the utility model relates to a kind of layering and administers railway cutting route frost damage prevention structure, belong to railway construction neck
Domain.
Background technique
The track freeze injury of railway cutting location is one of the Common Diseases of severe cold area railroad track, and tunnel, viaduct are inferior
The rail track at place is cutting location, and route geographical location is low herein, and basic water content is big, and therefore, ballast bed of track freezes swollen
Swollen is a kind of inevitable natural phenomena.Freeze injury can not only accelerate the dirty and ballast of railway roadbed to fall into the development of slot, but also can promote
Make roadbed that other diseases occur, influences the stability of roadbed, meanwhile, freeze injury can also be such that the operating condition of track deteriorates, especially
It is replaced as frequently as backing plate, substantially reduce sleeper and is coupled the service life of fastener.
The presence of freeze injury not only increases the labour of track maintenance and repair, increases operation expenditure, and can make route matter
Amount decline；Serious freeze injury, or even jeopardize traffic safety.
Summary of the invention
It is obstructed the technical problem to be solved by the present invention is to provide a kind of layering and administers railway cutting route frost damage prevention knot
Structure, which carries out barrier aqueous vapor to rail layer, ballast covering and base course respectively, the mode of separated layer handling carry out it is subtle
Regulation and accurate adjustment in the case where reaching without heavy construction construction, solve route because of irregularity caused by freeze injury, guarantee
The operation of train safety and steady.
In order to solve the above problem, the specific technical solution of the utility model is as follows: a kind of layering barrier improvement railway cutting
Route frost damage prevention structure is equipped with draining system including roadbed, railway roadbed, sleeper, rail and the cutting slope protection of roadbed two sides in roadbed
System, the high both ends in the middle part of drainage system are low, and clinker insulating layer is arranged in the top of drainage system both ends lowest part；It is protected in cutting
The two sides on slope are equipped with slope drainage ditch, cover straw plaited insulating layer above slope drainage ditch.
Belt is set between railway roadbed and sleeper and adjusts module, guarantees two sides rail in same plane.
Rubber cushion plate is set between sleeper and rail, and rubber cushion plate mating connection tightening means for height-adjusting guarantees two sides rail same
Plane.
Layering barrier administers railway cutting route frost damage prevention structure and uses the row that high both ends are low among base course setting
Water system, it is ensured that winter drainage system it is good, guidance aqueous vapor to roadbed two sides disperse, reduce subgrade moisture content, roadbed side slope
Drainage equipment dredging is reinforced, and then devises slag layer and straw plaited frost retarding layer to pumping equipment, roadbed is administered from fundamental factor
Freeze injury.
Module is adjusted in ballast covering setting belt, guarantees the stability of ballast covering, reduces the modification degree of track.
The structure of rubber cushion plate is used in rail layer, not only mitigates freeze injury, but also guarantees that two rails are horizontal.
Layering barrier is administered railway cutting route frost damage prevention structure and is had the advantage that
(1) make filler with full combustion, the light uniform clinker of ventilative fritter, the aqueous vapor of preferable drainage base course, and
Winter is cold-proof；
(2) straw plaited insulating layer is low in cost, the recyclable multiplexing of annual winter；
(3) railway roadbed belt adjustment layer freely can be turned up or reduce orbit altitude, and straight line, curve are applicable in, strong operability；
(4) layering barrier administers railway freeze injury technology and is not required to engineering construction, and directly carrying out ongoing operations can preferably control
Manage the route freeze injury in the engineering constructions difficulty locations such as tunnel, viaduct；
(5) railway cuts off traffic influence caused by avoiding because of engineering construction.
Detailed description of the invention
Fig. 1 is the schematic diagram that railway cutting route frost damage prevention structure is administered in layering barrier.
Specific embodiment
As shown in Figure 1, railway cutting route frost damage prevention structure, including roadbed 1, railway roadbed 2, sleeper are administered in a kind of layering barrier
3, the cutting slope protection 5 of rail 4 and roadbed two sides, roadbed is selected to be filled out by full combustion, the light uniform clinker of ventilative fritter
Material, light and ventilation, and there is preferable heat-insulating and cold effect, drainage system 6, the middle part of drainage system 6 are equipped in roadbed 1
High both ends are low, and clinker insulating layer 7 is arranged in the top of 6 both ends lowest part of drainage system；Side is equipped in the two sides of cutting slope protection 5
Slope gutter 8, covering straw plaited insulating layer 9 plays good surface layer drainage system anti-frost protection above slope drainage ditch 13, guarantees
Mountain spring water is in winter smoothly trickle downwards by the time, reduces base course water content, to achieve the purpose that mitigate route freeze injury.
Belt adjustment layer 10 is set between railway roadbed 2 and sleeper 3, and selecting specification is 200 millimeters × 400 millimeters, 10 millimeters
Or 20 millimeters thick ledger line belt, guarantee two sides rail 4 in same plane.
Rubber cushion plate 11 is set between sleeper 3 and rail 4, and 11 mating connection tightening means for height-adjusting 12 of rubber cushion plate is detained using being turned up
Part is renovated with the method that pillow upper padding plate combines, and is encased inside the rubber cushion plate no more than 20 millimeters, guarantees two sides rail 4 same
Plane.
The implementation for administering railway freeze injury technology is obstructed by layering, roadbed insulating layer can effectively prevent roadbed from freezing 50 millis
Rice；It rests the head on lower belt and adjusts 30 millimeters of module adjusting track height；Rubber cushion plate cooperates 20 milli of tightening means for height-adjusting adjusting track height
Rice.This technology is always turned up 100 millimeters, can effectively solve the route freeze injury in the inferior limitation location of tunnel, viaduct, avoids frequently more
The construction of lane-change bed.
The advantages of railway cutting route frost damage prevention structure is administered in the layering barrier of the application:
(1) by separated layer handling, achieve the purpose that rail track ride comfort, avoid replacement roadbed, railway roadbed engineering, save
Huge engineering cost；
(2) roadbed lower part gutter clinker insulating layer once fills completion, and ballast covering and rail layer can pass through ordinary maintenance
Operation is completed, construction is simple；
(3) personnel and equipment breakdown when engineering construction are avoided, reduces and goes because administering freeze injury route not in time
Vehicle accident, method operation is simple, and risk factor is few, is suitble to popularize in an all-round way in freeze injury location.
