7、、渗透性小的结石体；取材容易，配方简单，操作易于掌握；无环境污染，价格便宜等。水泥注浆适用于软粘土、粉土、新近沉积粘性土、砂土提高强度的加固和渗透系数大于10-2cm/s的土层的止水加固以及已建工程局部松软地基的加固。6.1.2．机具设备灌浆设备主要是压浆泵，其选用原则是：能满足灌浆压力的要求，一般为灌浆实际压力的1.2~1.5倍；应能满足岩土吸浆量的要求；压力稳定，能保证安全可靠地运转；机身轻便，结构简单，易于组装、拆卸、搬运。水泥压浆泵多用泥浆泵或砂浆泵代替。国产泥浆泵、砂浆泵类型较多，常用于灌浆的有BW-

8、250/50型、TBW-200/40型、TBW-250/40型、NSB-100/30型泥浆泵以及100/15（C-232）型砂浆泵等。配套机具有搅拌机、灌浆管、阀门、压力表等，此外还有钻孔机等机具设备。6.1.3．材料要求及配合比（1）水泥用强度等级32.5或42.5普通硅酸盐水泥；在特殊条件下亦可使用矿渣水泥、火山灰质水泥或抗硫酸盐水泥，要求新鲜无结块。（2）水用一般饮用淡水，但不应
