Description
Technical field
This utility model is related to coal receiving bunker, more particularly, to a kind of Novel underground unload coal groove structure arrangement, particularly to one kind
Novel reinforced concrete underground box automobile coal receiving bunker structural arrangement form.
Background technology
Coal receiving bunker is a kind of structures of conveying coal and other particulate species mineral, applies wide especially in thermal power plant
General, due to the growing tension of thermal power plant fire coal demand and ecological requirements, coal receiving bunker is as closed series connection transhipment coal body system
In first term, it is generally characterized by located underground, and typically at ten meters about, width changes buried depth from several meters to more than ten meters, length
From tens meters to 100 meters, it is applicable to the modes such as automobile is unloaded coal and train is unloaded coal, closure is good, transports coal ability
By force, thermal power plant plays important role, be also one of higher structures of cost in power plant.
Traditional coal receiving bunker is generally box underground structure, and coal bunker, from top downward, stretches out Liang Laizhi from side-walls
The pressure of support coal bunker, side soil pressure mainly kept out by side wall, and middle standing pillar is simultaneously chosen platform from post and unloaded coal, but with unloading
The increasing of coal trench depth, the increasing of side wall root institute's bending moment and shearing, sidewall thickness also increases therewith, and bring is coal receiving bunker
Overall cost increases, and difficulty of construction increases, and globality is general, and the structure to coal receiving bunker and cost-effectiveness requirement are required for carrying out excellent
Change.
Utility model content
In order to solve in existing coal receiving bunker arrangement, economic performance is poor, and concrete usage amount is big, and difficulty of construction is big, and structure is overall
The problems such as performance is general, provide a kind of Novel underground unload coal groove structure arrangement.
This utility model employs the following technical solutions：
A kind of underground track hoppers, the coal receiving bunker body constituting including the relative side wall of base plate and two, the opposite face of two side walls
On be symmetrical arranged two coal bunkers, two coal bunkers are pyramidal structure wide at the top and narrow at the bottom, and coal bunker bottom level chooses formation platform, two
There is between platform through hole, coal receiving bunker body top setting top straining beam.
The platform of described two coal bunkers is oppositely arranged.
Described coal bunker, side wall, base plate are the reinforced concrete structure pouring molding.
Described base plate external both sides Kuan Chu side wall.
Described coal receiving bunker body width is 6m ~ 15m.
Described top cross-bar is no less than one, in the setting of coal receiving bunker body head clearance.
Angle between described coal bunker and horizontal plane is 50 ° ~ 70 °.
A kind of underground track hoppers according to claim 1 it is characterised in that：Described platform（4）The part chosen is not
More than 2m.
The underground track hoppers structure arrangement amount of unloading coal of the present utility model is big, and integral arrangement stress is more reasonable, stability
Good, save concrete material, the promoting the use of of the demand of the low condition of difficulty of construction, more conducively underground track hoppers.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of prior art.
Specific embodiment
The utility model proposes a kind of new underground track hoppers, including 1, two side walls 2 of base plate and two coal bunkers 3, coal
Bucket 3, side wall 2, base plate 1 may be selected to pour the reinforced concrete structure of molding.Two side walls 2 are oppositely arranged on base plate 1, two
Coal bunker 3 is separately positioned on the opposite face of two side walls 2, and two coal bunkers 3 are set to pyramidal structure wide at the top and narrow at the bottom, taper coal bunker
3 bottom level extends and forms platform 4, has through hole, coal receiving bunker body top setting top straining beam 5, top between two platforms 4
Straining beam 5 number is indefinite, is disposed on coal receiving bunker body top as needed.The platform 4 of two coal bunkers 3 is oppositely arranged, be easy to into
Row transhipment coal.
Base plate 1 both sides external wide go out side wall 2, that is, bottom base plate width be wider than coal receiving bunker body width.Coal receiving bunker body width one
As be set to 6m ~ 15m.Base plate 1 is to bear superstructure load and moment of flexure that sidewall earth pressure transmits and shearing, base plate 1 thickness
Determined according to geological conditions, between generally 600mm～1500mm, both sides can slightly wider go out coal receiving bunker 1m, main mesh
Also for increasing base plate bearing capacity and offsetting the moment of flexure that side wall conduct, base plate 1 bottom method for processing foundation regards to be had
Body situation determines to change using subsoil to fill out or carry out piling process.
Side wall 2 main purpose is conduction superstructure vertical force and side soil pressure, rises and form a connecting link in total
Effect link coal bunker 3 and base plate 1, side wall 2 thickness determines according to coal receiving bunker buried depth and width, generally 500mm～1000mm.
Coal bunker part 3 main purpose is to unload coal, and topples over, from top, the coal getting off and slides to platform, Ran Houtong by coal bunker
Cross feeder coal is gone to belt and be transported to elsewhere.Side wall 2 and coal bunker part 3 are connected by this utility model, middle
Do not set beam to support, transferring platform 4 is extended to directly down by coal bunker 3, coal bunker 3 is generally 50～70 degree with horizontal plane angle
Between, for reducing concrete usage amount, typically encorbelmenting in coal bunker bottom, has space between coal bunker 3 bottom and side wall 2.
Platform 4 be coal bunker 3 horizontal-extending choose part, platform 4 physical dimension is typically changed to 200mm from 500mm, put down
Platform typically connects lower belt by feeder, and platform 4 is chosen width and is generally no greater than 2m.
The purpose of setting top straining beam 5 is to allow structure more monolithic stability, and also to carrying the conduction of coal double-edged fine-toothed comb
The load coming, straining beam 5 spacing is generally 6m, and straining beam 5 span and sectional dimension need to according to coal receiving bunker width adjustment, span one
As be not more than 15m, wide × High variation is between 300mm × 900mm～500mm × 1500mm.
Coal receiving bunker body can arrange staircase to enter bottom maintenance in end, can arrange vent at middle or two ends and protect
Card air circulation, vent size determines according to coal receiving bunker size, generally 1m × 1m about, simultaneously for meeting fire prevention and illuminating
Demand, can install fire protection pipeline, the device such as arrangement cable testing bridge in coal receiving bunker.
This utility model underground track hoppers structure arranges beautiful design, more meets structural mechanics mechanical characteristic, especially in coal
Bucket 3 and side wall 2 are inclined upwardly position, and it is more reasonable using space inside soil pressure mode suffered by outside, coal receiving bunker to change, and reinforcing bar mixes
Solidifying soil usage amount about reduces 5%～10% than the coal receiving bunker of ability of unloading coal on an equal basis, accordingly overall civil engineering cost reduce 5%～
10%, and globality is more preferably, eliminates middle standing pillar, and construction is convenient, also decreases the construction period simultaneously, reduces overall
Investment.
Above-described is only preferred implementation of the present utility model it is noted that for those skilled in the art
For, under the premise of without departing from this utility model general idea, some changes and improvements can also be made, these also should be considered as
Protection domain of the present utility model.
