Soil pressure shield argillaceous muck composite curing agent and curing method thereof
The invention aims to provide an earth pressure shield argillaceous muck composite curing agent and a curing method thereof, and belongs to the technical field of large municipal construction project shield muck treatment. The composite curing agent is composed of a curing agent and an activating agent, and the mass fraction of the muck is 100%, the mass fraction of the curing agent is 1.0%-5.0%, and the mass fraction of the activating agent is 1.2%-6%; and the curing agent comprises the following components in percentage by mass: 46.2%-57% of a consolidation agent, 14.3%-23.1% of a coagulation accelerator and 28.6%-30.8% of a reinforcing agent. The invention mainly solves the technical problems of high curing agent dosage, high cost, long curing time and high alkalinity of dried soil leachate in the existing shield muck curing treatment technology.
本发明的目的在于提供一种土压盾构泥质渣土复合固化药剂及其固化方法，属于大型市政建设工程盾构渣土处理技术领域。复合固化药剂由固化药剂和激活剂组成，渣土、固化药剂和激活剂的质量分数依次为100%、1.0%~5.0%、1.2%~6%；固化药剂的组份及质量分数为固结剂46.2%~57%，促凝剂14.3%~23.1%，增强剂28.6%~30.8%。本发明主要解决了现有盾构渣土固化处理技术存在的固化剂用量大、成本高、固化时间长及干化土浸出液碱度高的技术问题。
