Description
Technical field
This utility model relates to a kind of gravelly soil core-wall material preparation facilities for earth-rock works, belongs to Hydraulic and Hydro-Power Engineering field.
Background technology
Along with the Devoting Major Efforts To Developing of China's western part hydroelectric resources, the construction of high earth-rock works is on the increase, domestic construction or plan to build into
A collection of 200～the high earth and rockfill dam of 300m level, its core-wall material demand often reaches hundreds of all places.
It is said that in general, seepage prevention of core wall body does not require nothing more than has preferable barrier properties, and should have higher shear resistance.But,
According to the domestic complete 300m level high earth and rockfill dam construction built and plan to build and reconnoitre analysis in detail, natural impermeable soil material source is difficult to meet rule
Model requirement, needs the mode using admixture gravel to be modified, forms gravelly soil, to improve its shear resistance.
At present, earth-rock works precordial distress blends " tiling is vertical adopts " arrangement and method for construction that general employing is traditional, its main technique stream
Cheng Wei: stock ground exploitation → earth material and building stones transport to blend facade in layering tiling in field → blendings field → blend field exploit blending →
The upper dam of admixture transport.
Traditional tiling Li Caifa construction also exists that automatization level is low, production efficiency is low, quality stability is poor, floor space
Greatly, high cost problem big by weather influences such as rainfalls；Additionally, the hydroelectric project of China's construction is located in high waterway between mountains mostly
Canyon, construction site is narrow, uses the vertical mode of adopting of tiling to carry out blending and certainly will be limited by field, affects engineering construction progress.
High earth and rockfill dam gravelly soil core-wall material quantities is big, and core-wall material blends and needs efficient and stable blending technique badly, to guarantee engineering construction
Construction speed and the permanent operation of dam body.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of structural manufacturing process to be simple and convenient to operate, use with low cost
In the gravelly soil core-wall material preparation facilities of earth-rock works, to solve that existing blending mode construction technology is loaded down with trivial details, with high costs, to execute
The difficult problems such as work lack of space, to improve blending ability, to reduce blending cost.
The gravelly soil core-wall material for earth-rock works is the technical scheme is that by solving above-mentioned technical problem this utility model
Preparation facilities, including the multiple hoppers being arranged in series, is connected by batch mixing belt between adjacent two hoppers, batch mixing belt
Feed end coordinate be located at below the discharging opening of hopper, discharge end coordinate be located at after the charging aperture of a hopper, being subject to foremost
The charging aperture cooperation of hopper is provided with gravel feed belt, earth material feed belt.
Further: hopper is taper.
Further: the inclination angle of hopper sidewall is 50 °～60 °.
Further: hopper discharging opening at the width of side, batch mixing belt width direction, for batch mixing belt width 0.55～
0.65 times.
Further: the discharge end of gravel feed belt, the discharge end of earth material feed belt are located at same vertical plane.
Further: the discharging opening cooperation of the hopper of least significant end is provided with outfeed belt.
Further: outfeed belt cooperation is provided with water replanishing device.
The beneficial effects of the utility model are: during enforcement, simultaneously toward hopper charging aperture conveying gravel material foremost and earth material,
Transferred by multiple hoppers, a plurality of batch mixing belt again, earth material and gravel material during free-falling by hopper sidewall
Counteracting force, changes running orbit, and meanwhile, between earth material and gravel material, internal friction angle is different, therefore makes two kinds in motor process
Material constantly collides with each other, blends, and after the blending of multiple hoppers, reaches the purpose blended.This apparatus structure letter
Single, easy to operate, with low cost, convenient enforcement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Labelling in figure: 1-hopper, 2-batch mixing belt, 3-gravel feed belt, 4-earth material feed belt, 5-outfeed belt.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, this utility model includes the multiple hoppers 1 being arranged in series, by mixed between adjacent two hoppers 1
Material belt 2 connects, and the feed end cooperation of batch mixing belt 2 is located at below the discharging opening of hopper 1, discharge end cooperation is located at rear one
The charging aperture of hopper 1, the charging aperture cooperation of hopper 1 foremost is provided with gravel feed belt 3, earth material feed belt 4.
Hopper 1 quantity and corresponding batch mixing belt 2 quantity should determine according to scene test, and hopper 1 quantity is generally 3 or 4.
Hopper 1 is preferably taper, it addition, the inclination angle of hopper 1 sidewall is preferably 50 °～60 °.Under so can facilitating
Material, thus prevent putty, blend effect preferable simultaneously.
For avoiding material to trickle down, it is preferable that hopper 1 discharging opening width in batch mixing belt 2 width side, for batch mixing
0.55～0.65 times of belt 2 width.
Preferably, the discharge end of gravel feed belt 3, the discharge end of earth material feed belt 4 are located at same vertical plane, and i.e. two
Person overlaps in vertical direction, is beneficial to soil stone mixing.It addition, gravel feed belt 3, earth material feed belt 4 are preferably disposed to
The same side of hopper 1 charging aperture.
Deliver to destination for convenience of the material after blending, outfeed belt can be equipped with at the discharging opening of the hopper 1 of least significant end
5, it addition, also water replanishing device can be equipped with at outfeed belt 5, the moisture content of the material after regulating blending.Certainly, also
Can use other transloading equipment, the material after blending is transported to store up field watering and shelving.
