Shield synchronous grouting slurry
The invention discloses shield synchronous grouting slurry which comprises the following components in percentage by weight: 60%-90% of shield muck, 5%-20% of a cementing material, 0.01%-1% of a curing agent, 1%-10% of an accelerator, 0.01%-1% of a water reducing agent and the balance of water, and the mixing ratio of the shield muck is 60%-90%, the mixing ratio of the cementing material is 5%-20%, the mixing ratio of the curing agent is 0.01%-1%, the mixing ratio of the accelerator is 1%-10%, and the mixing ratio of the water reducing agent is 0.01%-1%. The mixing proportion of the water is 20%-60%. According to the shield synchronous grouting slurry composition mixing proportion, shield muck of a composite stratum is solidified, so that the shield muck meets the shield synchronous grouting requirement, the shield muck is adopted to a large extent, muck outward transportation is reduced, the construction cost is reduced, and environmental pollution is avoided.
本发明公开了一种盾构同步注浆浆液，组成包括盾构渣土、胶凝材料、固化剂、速凝剂、减水剂及水，盾构渣土的配合比为60％‑90％，胶凝材料的配合比为5％‑20％，固化剂的配合比为0.01％‑1％，速凝剂的配合比为1％‑10％，减水剂的配合比为0.01％‑1％，水的配合比为20％‑60％。本发明提供一种盾构同步注浆浆液组成配合比，针对复合地层的盾构渣土进行固化，使盾构渣土满足盾构同步注浆需求，并较大限度地采用盾构渣土，减少渣土外运，降低施工成本，避免环境污染。
