Wall protection slurry for underground scour prevention wall, preparation method and application
The invention belongs to the technical field of building construction materials, and discloses wall protection slurry for an underground scour-proof wall, a preparation method and application. Raw materials of the wall protecting slurry for the underground impingement wall comprise bentonite, carboxymethyl cellulose, sodium carbonate, sodium silicate, nanometer aluminum oxide and modified polytetrafluoroethylene fibers, and the modified polytetrafluoroethylene fibers are prepared through reaction of polytetrafluoroethylene fibers, MPTMS and butyl acrylate. All indexes of the wall protection slurry for the underground scour prevention wall can meet the requirements of circulating slurry indexes, the wall protection slurry can be well suitable for construction of the underground scour prevention wall of a stratum with much sand and gravel distribution, low compactness and high porosity, the slurry wall protection and collapse prevention effects are good, and the stability of a groove wall is good.
本申请属于建筑施工材料技术领域，本申请公开了一种地下防冲墙用护壁泥浆、制备方法及应用。本申请中的地下防冲墙用护壁泥浆的原料包括膨润土、羧甲基纤维素、纯碱、硅酸钠、纳米氧化铝和改性聚四氟乙烯纤维，其中，改性聚四氟乙烯纤维由聚四氟乙烯纤维和MPTMS、丙烯酸丁酯反应制得。本申请中制得的地下防冲墙用护壁泥浆的各项指标均可以满足循环泥浆指标的要求，能够很好地适用于砂和砾石分布多且密实性低、孔隙率高的地层的地下防冲墙施工，泥浆护壁和防塌效果较好，槽壁稳定性良好。
