Sandy stratum slurry shield slurry regulation and control green admixture and preparation method thereof
The invention discloses a sandy stratum slurry shield slurry regulation and control green admixture and a preparation method thereof, and belongs to the field of slurry shield slurry regulation. The sandy stratum slurry shield slurry regulation and control green admixture comprises 40-70 parts of a green polymer material, 10-15 parts of an environment-friendly surfactant, 5-10 parts of a cellulose derivative, 2-5 parts of a mineral admixture, 2-3 parts of a pumping agent and 3-8 parts of a pH regulator. According to the additive, the viscosity of the slurry can be remarkably improved, safe and smooth implementation of construction is guaranteed, the improved slurry can form a stable mud film on a sandy stratum, the improvement effect is improved, and in addition, the components of the green additive for regulating and controlling the slurry are all green and pollution-free and can be gradually decomposed as time goes on.
本发明公开了一种砂性地层泥水盾构泥浆调控绿色外加剂及其制备方法，属于泥水盾构泥浆调节领域，所述砂性地层泥水盾构泥浆调控绿色外加剂包括绿色高分子材料40‑70份、环保型表面活性剂10‑15份、纤维素衍生物5‑10份、矿物掺合料2‑5份、泵送剂2‑3份以及pH调节剂3‑8份。本发明的外加剂可以显著增加泥浆的黏度，保障施工的安全顺利实施，改良后的泥浆可在砂性地层形成稳定泥膜，提高了改良效果，此外，本发明提供的泥浆调控绿色外加剂所构成组分都是绿色无污染的，可以随着时间推移逐渐分解。
