Abstract
The invention discloses a kind of I type double block type ballastless railway roadbed concrete construction curing means of CRTS-, including the geotextiles and plastic film on railway roadbed concrete, setting maintenance water pipe (8) between geotextiles and plastic film, there is row's aperture in maintenance water pipe (8), maintenance water pipe (8) is connected with water supply device.After the completion of gravity line is laid with, the Landfill covering plastic film on I type double block type ballastless railway roadbed concrete surface of CRTS-.Gravity line forms the closed wet environment suitable for I type double block type ballastless railway roadbed concrete curing of CRTS- by the continual flowing water of tap hole in plastic film, while achieving the purpose that control plastic film inner concrete temperature.
Description
Technical field
The invention belongs to technical field of construction equipment, and in particular to a kind of railway roadbed concrete construction curing means.
Background technique
Mountain area mostly uses I type double-block type ballastless track system of CRTS- at present, since sleeper is C60 precast concrete, railway roadbed
C40 high performance concrete, in addition there are also edge insulator iso-stress centrostigmas, so railway roadbed cracking has become I type double-block type pair of CRTS-
The unavoidable common quality defect of block type ballastless track structure.
Especially I type double block type ballastless railway roadbed of roadbed section CRTS- due to day and night temperature it is big, railway roadbed concrete summer is round the clock most
The big temperature difference is up to 40 degree, and after pouring ballastless track bed concrete, due to the effect of expanding with heat and contract with cold repeatedly, in 2 months, ballastless track bed is mixed
Solidifying soil can generate a large amount of face crack: mainly from sleeper crack at edge；Crack down from roadbed, crackle present it is big, under
Small phenomenon.
Therefore I type double block type ballastless railway roadbed construction and maintenance of CRTS- becomes the important means of anti-railway roadbed concrete cracking, existing
Common practice is to set up special maintenance teams and groups, and ceaselessly sprinkling maintenance carries out moisturizing, temperature control, splits to reduce ballastless track bed concrete
Line；It was verified that maintenance is well-done, the crackle of ballastless track bed 80% can be reduced.And there is sprinkling and mend the uniform, time in nourishment
Unstable problem.
Summary of the invention
Technical problem solved by the present invention is being provided aiming at the problem that current railway roadbed concrete curing is using artificial sprinkling
A kind of curing means of automation.
The technical scheme adopted by the invention is as follows:
A kind of I type double block type ballastless railway roadbed concrete construction curing means of CRTS-, including the geotextiles and modeling on railway roadbed concrete
Expect film, setting maintenance water pipe between geotextiles and plastic film, conserving has row's aperture on water pipe, maintenance water pipe and the dress that supplies water
Set connection.
Water supply device water pumper, water inlet water pipe, high-level water storage case, Cistern valve and retort stand, high-level water storage case are mounted on
On retort stand, water pumper is connected by water inlet water pipe, maintenance water pipe is connected by Cistern valve.
A set of curing means is arranged at interval of 25-35m along route longitudinal direction, is mounted between two lines road, each high position
Water tank connects two maintenance water pipes.
Ground 1.6-2 meters of high-level water storage case distance from bottom.
It protects on water pipe and one apopore is set every 20-30cm, shield water pipe one end blocks, and one end connects Cistern valve.
Beneficial effects of the present invention: spray tube is clipped between geotextiles and plastic film, moisture diffusion can be made to obtain more
Block more evenly, continual and steady water supply may be implemented by water supply device, keep concrete humidity, and it is mixed to effectively increase road bed board
Coagulate the cracking resistance of soil.
Detailed description of the invention
Fig. 1 is the schematic diagram of apparatus of the present invention；
In Fig. 1,1- high-level water storage case, 2- is intake water pipe, and 3- Cistern valve, the right line of 4- poured a section ballastless track bed outer edge, 5-
Left line line midline, 6- retort stand, the right line line midline of 7-, 8- conserve water pipe, and the left line of 9- does not pour a section ballastless track bed inner edge,
The right line of 10- has poured a section ballastless track bed inner edge, 11- water pumper.
Specific embodiment
Install and use step
1) high water tank 1 is installed: using plastic cistern, volume 1m3, water tank bottom is away from ground 1.8m, bottom installation Cistern valve
3, to control water flow size, high water tank 1 is mounted among two lines road.
2) add water into high water tank 1: high water tank 1 connects water pumper by water inlet water pipe 2, starts at water source and draws water
Machine 11 supplies water into high water tank 1, fills it up with water tank.
3) paving geotextiles cover the ballastless track bed poured: after ballastless track bed concrete final set, form removal, and ballastless track bed
Concrete covers geotechnological cloth bag and wraps up in.
4) water pipe 8 is conserved on geotextiles upper berth: maintenance water pipe 8 is spread along ballastless track bed face transverse direction absolute altitude highest point, along maintenance
The tap hole of 3mm is arranged at interval of 25cm on gravity line for water pipe 8, and is higher by concrete surface, and gravity flow spray tube one end blocks, separately
One end is connected to Cistern valve 3.
5) paving plastic film covers: the paving plastic film covering in geotextiles and gravity flow spray tube, plastic film are thick
0.2mm；Plastic film side is clamped with clip, and the plastic film that bottom reserves one fixed width more is pushed down with small sandbag, prevents wind
Blow film open.
6) gravity line is conserved from jet flow: maintenance water pipe 8 connects with 1 bottom Cistern valve 3 of high water tank, opens Cistern valve
3, it passes water through tap hole free jet and goes out, keep concrete face moist, maintenance 14 days or more；It (supplies water by adjusting water flow size
Valve) and the aperture of discharge orifice adjust effective maintenance faces of dropper two sides, until water flow covers all concrete surfaces.
One maintenance unit is set at interval of 30m along route is longitudinal, in maintenance processes, send special messenger's tour, it is found that water flow is unsmooth or water tank
Anhydrous situation should exclude in time；If it find that concrete local surfaces have dry phenomenon don't be nervous, also need to look at this time
Whether the presence of fog is had on film, because the presence of fog, which has been proven that inside film, has had enough humidity, and
And it is greater than 95%；The care environments under curing membrane are inspected periodically, if it find that there is water shortage, timely feed-tank adds water；Film
The phenomenon that if there is being opened by wind, covering is fixed again.
7) step 1) -6 is repeated), until completing entire ballastless track bed construction.
