Shield backfill grouting slurry and preparation method thereof
The invention relates to the technical field of shield grouting, in particular to shield wall post-grouting slurry and a preparation method thereof.The shield wall post-grouting slurry comprises water and the following components in percentage by weight: 8-10% of a curing agent, 8-12% of Portland cement and 78-84% of silty clay, and the weight of the water is 90-95% of the total weight of the curing agent, the Portland cement and the silty clay. The raw materials of the shield wall post-grouting slurry are all fine powder, the groutability is ensured while the strength is ensured, and the silty clay plays a role of a framework and ensures the groutability of the slurry. According to the shield wall post-grouting slurry, the groutability in the transportation process is guaranteed, the high fluidity before grouting is guaranteed, the strength can be instantly increased after the slurry is injected, and meanwhile the problem that the quality of a wall post-grouting project is affected due to the fact that ordinary slurry is poor in waterproof performance in the prior art is solved.
本发明涉及盾构注浆技术领域，具体涉及一种盾构壁后注浆浆液及其制备方法，盾构壁后注浆浆液，包括水和如下重量百分比的各组分：固化剂8～10%、硅酸盐水泥8～12%和粉质黏土78～84%，水的重量是固化剂、硅酸盐水泥和粉质黏土总重量的90％～95％。本发明中的盾构壁后注浆浆液原材料均为细粉状，保证强度的同时保证了可注性，其中，粉质黏土起到骨架作用，并保证浆液的可注性。本发明中的盾构壁后注浆浆液保证了运输过程中的可注性，保证了注浆之前的高流动性，浆液注入后强度可瞬间上升，同时解决了现有技术中的普通浆液防水性能差的问题，影响壁后注浆工程质量。
