为充分利用工业废渣,降低滨海盐渍软基处治成本,提高处治效果,针对滨海盐渍软基不同于一般软基的特性,从物理改良和化学固化两个方面进行处治研究,研发了工业废渣双向钉形搅拌桩物理/化学联合处治滨海盐渍软基技术,同时阐述了施工工艺流程和质量控制。工程实践证明,工业废渣双向钉形搅拌桩处治滨海盐渍软基关键技术工艺先进,有利环保,具有良好的经济效益和社会效益,适用于滨海地区公路与城市道路盐渍软基加固处治与病害整治施工。
In order to make full use of industrial waste residue, reduce the treatment cost of coastal saline soft foundation and improve the treatment effect, aiming at the characteristics of coastal saline soft foundation different from the general soft foundation, from the physical improvement and chemical solidification two aspects of treatment research, developed industrial waste Two-way nail-shaped mixing pile physical / chemical treatment of coastal saline soft foundation technology, at the same time described the construction process and quality control. The engineering practice proves that the key technology of treating coastal saline soft foundation with industrial waste bi-directional nail-shaped mixing pile is advanced and environmentally friendly, and has good economic and social benefits. It is suitable for the treatment and disease treatment of roadbed and urban road in coastal area with salty soft soil reinforcement Remediation construction.
