Wall protection slurry for cast-in-situ bored pile and preparation method of wall protection slurry
The invention relates to the field of wall protecting slurry, and particularly discloses wall protecting slurry for a cast-in-situ bored pile and a preparation method of the wall protecting slurry for the cast-in-situ bored pile. 54 to 60 parts of bentonite; 1.7 to 2.7 parts of sodium carbonate; 7 to 8.2 parts of mineral aggregate; 14 to 24.6 parts of a weighting agent; 0.13 to 0.4 part of a cementing agent; 2-23 parts of an impermeable auxiliary material; the impervious auxiliary material comprises the following raw materials: a porous loading agent, nitro potassium humate and a coating agent, and the weight ratio of the porous loading agent to the nitro potassium humate to the coating agent is (10-16): (4-5): 5. The preparation process comprises the following steps: S1, preparing the cementing agent; s2, preparing an anti-seepage auxiliary material, and uniformly mixing the anti-seepage auxiliary material with a cementing agent to obtain a filler; s4, uniformly stirring the bentonite, the mixing water, the sodium carbonate, the mineral aggregate, the weighting agent and the filler to obtain the wall protection slurry. The cast-in-situ bored pile has the effect of preventing surrounding soil from permeating into the cast-in-situ bored pile.
本申请涉及护壁泥浆领域，具体公开了一种钻孔灌注桩用护壁泥浆及制备方法，护壁泥浆包括以下重量份的原料：拌合水900份；膨润土54‑60份；纯碱1.7‑2.7份；矿料7‑8.2份；加重剂14‑24.6份；粘固剂0.13‑0.4份；抗渗辅料2‑23份；抗渗辅料的原料包括多孔负载剂、硝基腐殖酸钾和包覆剂，多孔负载剂、硝基腐殖酸钾和包覆剂的重量比为（10‑16）：（4‑5）：5。其制备工艺为：S1、制备粘固剂；S2、制备抗渗辅料，抗渗辅料与粘固剂混合均匀得到填料；S4、将膨润土、拌合水、纯碱、矿料、加重剂、填料搅拌均匀得到护壁泥浆。本申请具有阻挡周围土体向钻孔灌注桩内渗透的效果。
