Wall protection slurry in uplift pile construction and preparation method of wall protection slurry
The wall protection slurry in uplift pile construction is characterized by comprising the following components: sodium bentonite, tap water, carboxymethyl cellulose, barite powder, edible corn starch and sodium carbonate. The ratio of the components is as follows: 1000 parts of tap water, 10-100 parts of sodium bentonite, 0.1-0.6 part of carboxymethyl cellulose, 2.5-4 parts of sodium carbonate, 5-50 parts of 200-mesh barite powder and 2-30 parts of edible corn starch. The preparation method of the wall protection slurry comprises the following steps: S1, adding 1/3 of the tap water into a stirring barrel according to the mixing ratio, and starting a slurry making machine; s2, adding sodium bentonite, sodium carbonate, barite powder and edible corn starch while continuously adding water into a quantitative water tank of the pulping machine, and stirring; and S3, adding carboxymethyl cellulose, continuously stirring, stopping stirring, putting into a new pulp tank, and standing and puffing for use.
一种抗拔桩施工中的护壁泥浆，其特征在于：包括以下成分，钠基膨润土、自来水、羧甲基纤维素、重晶石粉、食用玉米淀粉和纯碱；各成分的配比为，自来水1000份，钠基膨润土10～100份，羧甲基纤维素0.1～0.6份，纯碱2.5～4份，200目重晶石粉5～50份，食用玉米淀粉2～30份。该护壁泥浆的制备方法包括以下步骤：S1.按上述配合比先将1/3的自来水加至搅拌筒后，启动制浆机；S2.向制浆机的定量水箱不断加水的同时，加入钠基膨润土、纯碱、重晶石粉、食用玉米淀粉，进行搅拌；S3.加入羧甲基纤维素继续搅拌即可停止搅拌放入新浆池中，待静置膨化后使用。
