Premixed shield synchronous grouting material and preparation and application thereof
The invention relates to a premixed shield synchronous grouting material as well as preparation and application thereof. The premixed shield synchronous grouting material comprises the following components: cement, fly ash, fine sand, a rapid hardening agent, a water reducing agent, rubber powder, a water repellent, an expanding agent and water. The premixed shield synchronous grouting material provided by the invention has good cohesive force in a water-rich environment, is not easy to disperse, can maintain the stability and uniformity of the grouting material, prevents the grouting material from layering and bleeding in water, and ensures the quality and effect of the grouting material.
本发明涉及一种预拌盾构同步注浆料及其制备和应用，组分包括以水泥、粉煤灰、细砂、快硬剂、减水剂、胶粉、憎水剂、膨胀剂、水。本发明预拌盾构同步注浆料，在富水环境中具有良好的凝聚力，不易分散，能够保持注浆料的稳定性和均匀性，防止注浆料在水中发生分层和泌水，保证注浆料的质量和效果。
