Composite curing agent and curing and vacuum dehydration combined in-situ curing method
The invention belongs to the technical field of foundation treatment in civil engineering and transportation engineering, and relates to a composite curing agent and a curing and vacuum dehydration combined in-situ curing method, and the composite curing agent for high-water-content sludge is prepared from sludge, cement and a retarder according to the following mass percent. The doping amount of the cement is 4-16% of the mass of the sludge, and the doping amount of the retarder is 0.05-0.2% of the mass of the cement. According to the method, vacuum dehydration is introduced into a high-water-content sludge solidification project for the first time, the retarder is added, the cement solidification effect is further improved, the economic benefit is high, the construction method is simple, and complex construction processes and many large equipment are not needed.
本发明属于土木工程和交通运输工程中地基处理的技术领域，涉及一种复合固化剂及固化联合真空脱水就地固化法，用于高含水率淤泥的复合固化剂由淤泥、水泥、缓凝剂按照下述质量百分比配置而成。水泥掺入量为淤泥质量的4‑16%，缓凝剂掺入量为水泥质量的0.05%‑0.2%。本发明首次将真空脱水引用到高含水率淤泥固化工程中，并加入缓凝剂进一步提升水泥固化的效果，经济效益高，施工方法简易，不需要复杂的施工工艺和很多大型设备。
