Preparation method of bentonite slurry for slurry shield fast-plugging sandy stratum
The invention discloses a preparation method of bentonite slurry for a slurry shield fast-plugging sandy stratum, and belongs to the technical field of bentonite slurry preparation, the preparation method of the bentonite slurry comprises the following steps: S1, preparing bentonite-based slurry; s2, measuring the filter loss of the bentonite-based slurry in the S1, judging whether the filter loss of the bentonite-based slurry meets a filter loss control standard or not, if so, determining that the bentonite-based slurry is qualified, and otherwise, entering S3; s3, floury soil is added into the bentonite-based slurry, whether the filter loss meets the filter loss control standard or not is judged, if yes, the bentonite slurry added with the floury soil is qualified, and if not, the step S4 is executed; s4, sand grains of different particle size sections are added into the bentonite-based slurry added with the silty soil, and multiple parts of bentonite-based slurry containing the sand grains of different particle size sections and the silty soil are obtained; s5, measuring the filter loss of the multiple parts of slurry prepared in the previous step, and finding out the slurry with the minimum filter loss; s6, obtaining a bentonite-based slurry ratio with lower filter loss; according to the method, field personnel can be effectively guided to prepare the slurry.
本发明公开了一种泥水盾构快塞砂性地层的膨润土泥浆配制方法，属于膨润土泥浆配制技术领域，膨润土泥浆配制方法包括S1、配置膨润土基浆；S2、测定S1中的膨润土基浆的滤失量，判断膨润土基浆的滤失量是否满足滤失量控制标准，如满足，则膨润土基浆合格，否则进入S3；S3、向膨润土基浆中添加粉土，判断滤失量是否满足滤失量控制标准，如满足，则添加粉土后的膨润土泥浆合格，否则进入S4；S4、分别向添加粉土后的膨润土基浆添加不同粒径段的砂粒，获得多份含不同粒径段的砂粒且含粉土的膨润土基浆；S5、测定上一步骤所制得的多份泥浆的滤失量，并找出滤失量最小的浆液；S6、得到滤失量更低的膨润土基浆配比；该方法有效的指导现场人员对泥浆的配制。
