【摘要】：正BY12-VI型水中不分散注浆料:主要应用于突水的堵漏,使用时将1000 kg BY12-VI型加入到600 kg水中高速分散剪切乳化15 min,浆液细度小于0.05 mm,初始流动度25s、30 min流动度30 s,然后用压浆泵将浆液压进突水处,当浆体与水接触时不易被水分散掉,随着注浆压力的加大,浆液逐渐把水挤退到半径1~50m以外,水中7d抗压强度大于5 MPa,28 d抗压强度大于10 MPa,28 d抗渗强度大于P12。BY12-IA型早凝早强高强注浆料:与BY12-VI型配合主要应用于突水的堵漏和抢修,使用时将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.
