Description
Technical field
The present invention relates to hydraulic engineering technologies, prepare flood control using shale Extra-fine sand more particularly, to a kind of for the side of anti-stone
Method.
Background technique
The silt that the Yellow River is carried along into the Bohai Sea is above tens million of tons every year, yellow with the substantial increase of middle and upper reaches water
River part silt particle is deposited again in middle and lower reaches riverbed, and the silt particle of these siltations is based on shale Extra-fine sand, and also known as the Yellow River is in soil.
The flood control of the Yellow River middle and lower reaches will lay in a large amount of building stones every year.Since many locations of middle and lower reaches are located in Plain,
Away from stone pit kilometers up to a hundred, so long range freight charges reinforce the policy of environmental protection plus country, the flood control is set to be in for the price of anti-building stones
The gesture to rise steadily.If can on the spot with the preparation flood control of the Yellow River shale Extra-fine sand for anti-building stones, on the one hand can slow down under
The siltation for swimming riverbed, can substantially reduce flood control on the other hand for the price of anti-building stones, play the role of killing two birds with one stone.
Summary of the invention
The purpose of the present invention is to provide a kind of using the preparation flood control of shale Extra-fine sand for the method for anti-stone, and this method is simple
Easy, energy conservation and environmental protection has good economic benefit and social benefit.
To achieve the above object, the present invention can take following technical proposals:
It is of the present invention using shale Extra-fine sand preparation flood control for anti-stone method, be added in shale Extra-fine sand it is a certain amount of
Calcined clay, slag powders, flyash and sodium silicate, add water and stir uniformly and be squeezed into standby anti-stone briquet, warp after being aged 2 hours
Standby anti-stone finished product is obtained after maintenance；Wherein the shale Extra-fine sand and calcined clay, slag powders, the quality of flyash and sodium silicate
Per distribution ratio are as follows: shale Extra-fine sand 60% ~ 70%, calcined clay 10% ~ 15%, slag powders 5% ~ 10%, flyash 5% ~ 10%, sodium silicate
3%~5%；Additional water is the 13%-15% of material total amount.
The shale Extra-fine sand is the deposit of lower reaches of river；Main component is based on quartz, content >=90%, shale
Ingredient is clay, content < 5%.
The calcined clay is that clay (cohesive soil gathered materials on the spot, loess or silt) is calcined through 750 ~ 800 DEG C, so
Afterwards grinding at 150-200 mesh powder.
The slag powders be powder of the blast-furnace cinder through fineness 300-400 mesh made of grinding, main component be calcium oxide,
Silica and aluminium oxide, wherein calcium oxide content be 35% ~ 40%, silica content be 30% ~ 35%, alumina content be 10% ~
15%, also containing a small amount of magnesia, iron oxide etc..
The flyash is flying dust caused by coal burning, and main component is silica and aluminium oxide, wherein silica
Content is generally 45% ~ 50%, and alumina content is generally 30% ~ 35%, secondly also contains a small amount of calcium oxide and iron oxide.
The sodium silicate is the solid powder of modulus 2.0.
The external adding water uses tap water or free of contamination natural water, and water temperature is 30 ~ 50 DEG C, if water temperature is too low, flower bulb
Alkali is not easy to melt, and water temperature is too high, easily scald operator, causes industrial accident.
Standby anti-stone shape and volume size prepared by the present invention can be adjusted according to actual needs.After tested, finished product
Standby anti-stone uniaxial compressive strength can substitute building stones as flood control and use for anti-stone in 25MPa or more.
The advantage of the invention is that it is glutinous to add a small amount of calcining using the shale Extra-fine sand that the Yellow River middle and lower reaches are deposited as major ingredient
Soil, slag powders, flyash and sodium silicate preparation flood control are for anti-stone, and raw material is easy to get, and preparation method is simple, and slag powders and flyash are
The waste material of iron and steel enterprise and coal-burning utilities, waste utilization, energy conservation and environmental protection；The standby anti-stone monolithic quality of preparation is larger, is suitble to machinery
The problem of change is speedily carried out rescue work, and very good solution root stone is wandered away；It needs to cut into a mountain fried stone with the standby anti-stone of tradition, and by long-distance transport from adopting
The method that the transport of stone field comes is compared, and greatly reduces transportation cost and flood control cost, while the conjunction to shale Extra-fine sand on the spot
Reason utilizes the siltation for slowing down middle and lower reaches riverbed again.
