摘要:

随着城市轨道交通的快速发展,盾构渣土的高效处置已成为制约隧道工程可持续发展的关键问题。利用盾构渣土制备壁后注浆材料,不仅可实现渣土的就地资源化利用,显著降低注浆成本,也符合国家对于建筑固废“减量化、资源化、无害化”的政策导向。本文系统阐述了盾构渣土的来源、分类及现场减量化处理工艺,重点综述了利用盾构渣土制备壁后注浆材料的研究进展与工程应用情况。研究表明,经分级处理后,渣土中的粗颗粒可替代细骨料提供骨架支撑,细颗粒具备替代膨润土的潜力;通过优化固化剂体系、调控粒径分布与水固比,可有效提升渣土利用率,改善浆液的流动性、稳定性和抗压强度。工程实践表明,渣土基注浆材料在控制沉降、管片上浮和防渗等方面表现良好,但仍面临渣土成分差异大、缺乏标准规范及长期性能数据不足等挑战,未来需加强标准化与耐久性研究。

Abstract:

With the rapid development of urban rail transit, the efficient disposal of shield muck has become a key issue restricting the sustainable development of tunnel projects. Using shield muck to prepare backfill grouting materials can not only achieve the on-site resource utilization of muck, significantly reduce the grouting cost, but also conform to the national policy orientation of "reduction, resource utilization and harmless treatment" for construction solid waste. This paper systematically expounds the source, classification and on-site reduction treatment technology of shield muck, and focuses on summarizing the research progress and engineering application of using shield muck to prepare backfill grouting materials. The research shows that after classification treatment, the coarse particles in the muck can replace fine aggregates to provide skeleton support, and the fine particles have the potential to replace bentonite. By optimizing the curing agent system, regulating the particle size distribution and water-solid ratio, the utilization rate of muck can be effectively improved, and the fluidity, stability and compressive strength of the slurry can be improved. Engineering practice shows that the muck-based grouting materials perform well in terms of settlement control, segment floating and anti-seepage. However, they still face challenges such as large differences in muck composition, lack of standard specifications and insufficient long-term performance data. In the future, research on standardization and durability needs to be strengthened.
