Secondary grouting slurry for large-diameter shield in water-rich sand layer and seal plug thereof
The invention provides secondary grouting slurry for a large-diameter shield in a water-rich sand layer. The secondary grouting slurry for the large-diameter shield in the water-rich sand layer comprises common silicate cement, super-early strength sulfoaluminate cement and water. In the construction process of the secondary grouting slurry for the large-diameter shield in the water-rich sand layer, the labor investment is small, the construction process is simple and easy to operate, the durability is good, the control effect on upward movement of a segment is good, the construction cost is saved, the construction efficiency is improved, and the secondary grouting slurry is worthy of application and popularization in the water-rich sand layer.
本发明提出一种用于大直径盾构在富水砂层的二次注浆浆液，包括普通硅酸盐酸水泥、超早强硫铝酸盐水泥和水。本发明施工过程中投入人工少，简单易操作，耐久性好，且对管片上浮的控制效果更好，节省了施工成本，更提高了施工效率，值得在富水砂层中推广应用。
