Above-mentioned cement uses portland cement and/or Portland cement.
The fineness modulus of above-mentioned sand is 2~4；Apparent density is 2550~2650g/m3；Sand rate containing powder is 13~15%.
The grain composition of above-mentioned stone is 2.5~26mm；Apparent density is 2550~2580Kg/m2。
Above-mentioned additive uses water-reducing agent, flocculant, swelling agent or plastic-viscous admixture.
A kind of construction method being poured rock-fill concrete using above-mentioned underwater self-compaction concrete, is included the following steps：
One, barricade skeleton is built by laying bricks or stones around job location using enrockment；
Two, it is that template is arranged in the required storehouse surface for pouring rock-fill concrete again；
Three, underwater self-compaction concrete is poured in template, is conducted oneself with dignity using underwater self-compaction concrete and is flowed, is filled up completely The construction of rock-fill concrete is completed in enrockment gap.
In the step of above-mentioned steps three are flowed using underwater self-compaction concrete dead weight, accelerated under water from close using vibrator The flowing of real concrete.
Above-mentioned enrockment uses one or more compound in rubble, block stone, rubble ashlar or cobble；And the grain size of enrockment is not Less than 30cm.
A kind of preparation method of above-mentioned underwater self-compaction concrete, includes the following steps：
One, stone, sand, cement, flyash are put into blender in proportion, stir 15s；
Two, it is uniformly introduced in blender after mixing water and additive, after stirring 10min, you can be made.Compared to existing Technology, advantage of the invention is that：
A kind of underwater self-compaction concrete provided by the invention, compared with traditional underwater self-compaction concrete, Neng Gou Under the premise of the underwater self-compaction concrete for preparing equal quality, reduce the dosage of cement, stone and additive, using mixing greatly Flyash is measured, is realized while reducing cement consumption, reducing the construction cost of raw material, and can ensure that underwater self-compaction is mixed High fluidity of the solidifying soil not less than the underwater construction of C20 strength marks.
The construction method that rock-fill concrete is poured using the underwater self-compaction concrete of the present invention, using enrockment in construction ground It builds barricade skeleton around point by laying bricks or stones, then template is set for the required storehouse surface for pouring rock-fill concrete, poured in template under water from close Real concrete is conducted oneself with dignity using underwater self-compaction concrete and is flowed, is filled up completely enrockment gap, will not be washed away, formed it is complete, Closely knit, bonding well, meets intensity, the rock-fill concrete of anti-permeability performance requirement eliminates elder generation compared with traditional construction method It builds cofferdam and carries out the process that drainage of foundation pit creates dry work again, simplify construction procedure, improve construction efficiency and cost.
In addition, the art of this patent is very flexible, can also in conjunction with rock-fill concrete casting craft, using big gauge block stone, into One step reduce underwater concreting amount, reduce engineering comprehensive cost while, also make full use of block stone absorb heat the characteristics of, can The heat that hydrated reaction of cement is released is absorbed, the later stage is greatly reduced and the possibility of thermal cracking occurs, greatly increase construction Efficiency and save construction cost.
In addition, the construction method for pouring rock-fill concrete using the underwater self-compaction concrete of the present invention carries out power station side Slope underwater foundation pours, and hydropower station unit can not be shut down, and after concreting without longitudinal joint, concrete disclosure satisfy that C20 intensity is wanted It asks, the build in cofferdam can be effectively reduced, while reaching C20 underwater self-compaction concretes and C20 self-compacting concretes waterborne Performance requirement accelerates construction progress, and reduces construction investment and electric quantity loss.
