【摘要】:正BY12-VI型水中不分散注漿料:主要應用于突水的堵漏,使用時將1000 kg BY12-VI型加入到600 kg水中高速分散剪切乳化15 min,漿液細度小于0.05 mm,初始流動度25s、30 min流動度30 s,然后用壓漿泵將漿液壓進突水處,當漿體與水接觸時不易被水分散掉,隨著注漿壓力的加大,漿液逐漸把水擠退到半徑1~50m以外,水中7d抗壓強度大于5 MPa,28 d抗壓強度大于10 MPa,28 d抗?jié)B強度大于P12。BY12-IA型早凝早強高強注漿料:與BY12-VI型配合主要應用于突水的堵漏和搶修,使用時將1000 kg
[Abstract]:BY12-VI type non-dispersive grouting material in water: mainly used for water inrush plugging, In use, 1000 kg BY12-VI type was added to high speed dispersive shear emulsification of 1000 kg water for 15 min, slurry fineness less than 0. 05 mm, initial flowability 25 s, 30 min flow, 30 s. Then the slurry was hydraulic inrush into the water by pressure pump. When the slurry was in contact with water, it was not easy to get rid of water. With the increase of grouting pressure, the grouting fluid gradually pushes back the water beyond the radius of 1 ~ 50 m. Water 7 d compressive strength > 5 MPa,28 d compressive strength > 10 MPa,28 d impermeability strength is greater than P12.BY12-IA type early setting early strength high strength grouting material: combined with BY12-VI type is mainly used for water inrush plugging and urgent repair. 1000 kg is used when using.
