Description
Technical field
The present invention relates to the standby anti-stone structure that emergency work construction on a kind of river is commonly used, especially a kind of slag core concrete
Composite construction belongs to the technical field of dyke building for anti-stone and preparation method.
Background technology
Standby anti-stone is at flood control engineering vulnerable spots and river control works and a number of building stones of near zone deposit, is used
To meet emergency flood fighting urgent need.Investigation shows that the speedily carry out rescue work rate of wandering away of middle stone of the Yellow River is about 20~30%, the standby anti-Shi Shoushi of tradition
Work condition and material limitation, buttress shore protection root stone can not meet anti-impact requirement, easily be wandered away under current scour, make dam bank stable
Property is substantially reduced.With the progress of society, people are to rapid rescue and to improve the requirement speedily carried out rescue work in terms of effect more and more high.Often
Year the Yellow River jackstone amount used of speedily carrying out rescue work is tens ten thousand steres, because stone material is non-renewable resources, standby anti-stone used in emergency flood fighting
Procurement price rise year by year, it is higher as standby anti-stone cost from stone material, while also resulting in the wasting of resources.Therefore, the more than ten years
Lithotome is replaced to be developed the artificial stone material of many types, is mainly had:It is standby anti-that Yellow River mud sinters artificial stone material
Stone, is formed by a firing using ceramic production technology；Yellow River mud rolls standby anti-stone, and the non-autoclaved and unburned massive material for preparing is robbed for flood control
Danger；The unburned Yellow River mud of vibration moulding binder materials utilizes binder materials and activity excitant manufacturing artificial stone material for anti-stone；Sea
Bank wave resistance quadrangular pyramid concrete bodies, using concrete for making for anti-stone substitute.But these products exist production process it is complicated,
Cost is high, the shortcomings of be difficult to large-scale production, and abrasion resistance, freeze-thaw resistance of some products etc. have some problems, thus very
Difficult popularization and application.
Slag is the solid waste given off in steel manufacture process, and China discharges about 14,000,000 tons of slag every year,
And the steel slag utilization rate of China is only 22% or so, slag is largely stacked, not only waste of resource but also pollution environment.Due to slag
Quality is hard closely knit, and hole is few, and compression strength is high, with certain gelling, therefore can be raw material from slag, on the one hand
The intensity requirement of standby anti-stone can be reached, on the other hand slag can be comprehensively utilized again, the wasting of resources is reduced and environment is dirty
Dye.
