▎ 摘　　要

NOVELTY - New-type grouting material with stratum comprises GO-FA synergistic effect modified cement grouting material, where GO is oxidation graphene FA is fly ash, where the proportion is 0.15 pts. wt. oxide graphene, 400 pts. wt. cement, 100 pts. wt. fly ash, 5-8 pts. wt. accelerating agent, and 400 pts. wt. water, preparing new grouting material, firstly mix the cement, fly ash, and accelerating agent uniformly to obtain material A, then uniformly mix the graphene solution and water to obtain solution B, at last fully and uniformly stirring the solution B and material A, pouring the new grouting slurry to the rich water crushing belt formation through the grouting pump. USE - Grouting material with stratum for breaking the fractured zone rich in water (claimed). ADVANTAGE - The material has high fluidity, low water separation rate, controllable coagulation time, high calculus body strength, good anti-seepage performance, non-toxic, low-carbon green, simple operation, low-carbon green, and has high performance of water-rich crushing fracture zone grouting reinforcing and anti-seepage material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing new type grouting material with stratum for breaking the fractured zone rich in water, proportioning 0.15 pts. wt. oxide graphene, 400 pts. wt. cement, 100 pts. wt. fly ash, 5-8 pts. wt. accelerating agent, and 400 pts. wt. water, weighing the proportion material, firstly mixing and stirring the powdered cement and fly ash, continuously stirring for more than 2 minutes to obtain the uniformly mixed powder material A, then mixing 0.15 pts. wt. graphite oxide solution, and 400 pts. wt. water by ultrasonic wave, ultrasonically dispersing for not less than 5 minutes, uniformly mixing the oxidized graphene solution with water to obtain solution B, mixing and stirring the powder material A and solution B, firstly slowly stirring for 2 minutes, stirring speed is 140 r/minutes, quickly stirring for 3 minutes, stirring speed is 285 r/minutes, making it fully and uniformly mixing, making the oxidation graphene the solution and the gelled material is more contact, promoting the quick hydration reaction of the slurry, injecting the prepared grouting slurry into the rich water crushing belt stratum by the grouting pump.
