Roadbed filler for treating tunnel excavation waste salinized loess based on curing agent and preparation method of roadbed filler
The invention discloses a roadbed filler for treating tunnel excavation waste salinized loess based on a curing agent and a preparation method of the roadbed filler, and belongs to the technical field of comprehensive utilization of tunnel spoil, the roadbed filler comprises tunnel waste residues, the curing agent and water, the curing agent comprises 23-27 parts of magnesium slag, 3-5 parts of fly ash, 1-3 parts of an exciting agent, 6-8 parts of a reinforcing agent and 3-5 parts of an adsorbent, and the curing agent comprises a curing agent and a curing agent. The adsorbent is magnesium aluminum carbonate hydrotalcite. According to the method, high-content sulfate radicals in the tunnel waste residues are fully utilized, hydrated magnesium aluminosilicate and hydrated calcium aluminosilicate gel are generated by a curing agent in the curing process, and the hydrated magnesium aluminosilicate, the hydrated calcium aluminosilicate and cations in magnesium aluminum carbonate hydrotalcite are subjected to ion exchange and synergistic reaction to form a stable phase; the mechanical property and the environmental stability of the solidified soil are effectively improved.
本发明公开了一种基于固化剂处理隧道开挖废弃盐渍化黄土的路床填料及其制备方法，属于隧道弃土综合利用技术领域，其中所述路基填料包括隧道废渣、固化剂和水，所述固化剂包括镁渣23～27份，粉煤灰3～5份，激发剂1～3份，增强剂6～8份，吸附剂3～5份，所述吸附剂为碳酸镁铝水滑石。本发明充分利用隧道废渣中的高含量硫酸根，在固化过程中，固化剂生成了水化硅铝酸镁和水化硅铝酸钙凝胶，水化硅铝酸镁和水化硅铝酸钙与碳酸镁铝水滑石中的阳离子发生离子交换和协同反应，形成稳定相，有效提高固化土的力学性能和环境稳定性。
