Abstract
The utility model relates to a gangue road bed construction equipment. The gangue is the solid waste that coal mining process and coal washing in -process discharged, not only piles up the occupation of land, but also can spontaneous combustion contaminated air or arouse the conflagration, regard the gangue as road bed construction equipment's important material, and the home belongs to the originating at present. The utility model discloses the constitution includes: coal cash making layer (8), coal cash making layer include under the road bed and to handle layer (6), the road bed handle down a layer top making and have 2 layers gangue layer (1), 2 layers the gangue layer between the making have interval soil layer (4), gangue layer upper portion making have grave mound layer (2), the skin on coal cash making layer the soil property layer (3) of borduring has. The utility model is used for gangue road bed construction equipment.
Description
Technical field:
This utility model relates to a kind of gangue subgrade construction device.
Background technology:
Gangue is the solid waste of discharge during coal mining process and coal washing, not only piles up occupation of land, and can also spontaneous combustion contaminated air or cause fire, using gangue as the important materials of subgrade construction device, current state planted agent belongs to pioneering.Gangue is the mixture of carbonaceous, shale and arenaceous shale, has low heating value.Carbon containing
20%
~
30%
Some contains humic acid, and China has accumulated gangue about over the years
1000Mt
, and continue to every year discharge about
100Mt
Not only pile up occupation of land, and can also spontaneous combustion contaminated air or cause fire, this product using gangue as roadbed filling, make it turn waste into wealth, take full advantage of efficient resource, filling roadbed with coal gangues, both save occupation of land, reduce again engineering cost, utilize filling roadbed with coal gangues, decrease the gangue pollution to environment, beneficially environmental protection.
Utility model content:
The purpose of this utility model is to provide a kind of gangue subgrade construction device
Above-mentioned purpose is realized by following technical scheme:
A kind of gangue subgrade construction device, its composition includes: bastard coal making layer, and described bastard coal making layer includes processing under roadbed layer, and processing making above layer under described roadbed has
2
Layer bastard coal rock layers,
2
Between bastard coal rock layers described in Ceng, making has interval soil layer, described bastard coal rock layers top making to have grave mound layer, the outer layer of described bastard coal making layer to have soil property edging layer.
Described gangue subgrade construction device,
2
It is respectively arranged with sluicing french drain bottom bastard coal rock layers both sides described in Ceng, processes layer two bottom sides under described roadbed and be conveniently provided with gutter.
Beneficial effect:
1.
Of the present utility model is a kind of gangue subgrade construction device, bastard coal rock layers, soil property edging layer, interval soil layer, grave mound layer is mainly utilized effectively to carry out interlayer combination and can ensure that the total quality of roadbed, gangue is made to turn waste into wealth, take full advantage of efficient resource, filling roadbed with coal gangues, both save occupation of land, reduce again engineering cost, utilize filling roadbed with coal gangues, decrease the gangue pollution to environment, beneficially environmental protection.

:
According to embodiment
2
Described gangue subgrade construction device, the construction method of described gangue subgrade construction device, first it is to carry out roadbed treatment according to drawing, prepares lower floor's scope of operation；Carrying out gangue layer after processing layer making under roadbed, carry out soil property edging layer after bastard coal rock layers making, soil property edging layer completes laggard between-line spacing soil layer, and interval soil layer carries out gangue making layer after completing, and described gangue making layer completes laggard walking along the street base grave mound layer；Specific construction is as follows:
1
Bastard coal rock layers is constructed
1.1
Gangue transports:
Gangue uses the vehicle transport in irony compartment, if the temperature of gangue is too high, cooling of should sprinkling water, and application tarpaulin in compartment hides；
1.2
Grid cloth:
On ready sub-layer, the area gridding that can pave according to each car material, unload a car material in each grid, accomplish that quota is got the raw materials ready；
1.3
Bull-dozer paves, slightly puts down:
Pave gangue and carry out the most levelling, with manually picking except big particle diameter bastard coal stone and foreign material with bull-dozer；
1.4
Watering for the first time:
The water content of the gangue according to test and optimum moisture content, calculate required watering amount, spills water rate control at optimum moisture content for the first time
60%
；
1.5
First pressing:
All penetrate into when road roller is not glued in gangue and surface in watering for the first time and start to roll, use net weight to be not less than
20t
Road roller static pressure one time, the speed controlling of road roller exists
2~3km/h
, use net weight to be not less than
20t
Vibrated roller roll, use the big amplitude of low frequency and the little amplitude of altofrequency alternately to roll, rolling speed is
3~4km/h
, make gangue the most broken, reconfigure；
1.6
Second time watering:
At gangue surface uniform sprinkling, spill water rate control and exceeding gangue optimum moisture content
0
—
2
Percentage point；
1.7
Multiple pressure and final pressure:
Sprinkling water until second time and be fully infiltrated in gangue and when surface does not glues road roller, start multiple pressure, multiple pressure uses low frequency large-amplitude vibration to roll, and road roller speed controlling exists
3.5~4.5km/h
, multiple pressure
4
After Bian, carry out compactness inspection.Static pressure one time after qualified；
1.8
Maintenance:
After roller-compaction, often to sprinkle water in surface, keeps moistening, until constructing to next level.
. bound edge soil: bound edge soil grooving, fills width hanging wire grooving inside bound edge according to gangue.
. wall is constructed: construct according to normal roadbed filling.
. bastard coal rock layers is constructed: repeat
1
Operation.
. roadbed sealing: carry out roadbed sealing according to design.
