The invention relates to an environment-friendly high-strength solidified soil construction process. The construction process comprises the following steps: construction lofting, foundation pit digging, cement paving, dry mixing by a road mixer, initial pressing, diluting and spraying of an environment-friendly high-strength curing agent, re-mixing, re-pressing, slicking, rolling and curing. Or construction lofting, foundation pit digging, cement paving, cold regeneration equipment mixing, primary pressing, slicking, rolling and curing are conducted. In the construction process, the mixing ratio of the environment-friendly high-strength solidified soil is designed as follows: the ratio of the organic curing agent to the cement to the matrix soil is (0.01-0.05%): (2-15%): (85-98%), and the ratio of the inorganic curing agent to the matrix soil is (3-18%): (82-97%). According to the construction process, excellent physical and chemical properties and mechanical properties of the environment-friendly high-strength solidified soil after solidification can be guaranteed, the crushing effect of matrix soil blocks, the retarding effect of cement and the early strength effect of hydration of inorganic binding materials are improved, and the regrindability of the solidified soil is improved; meanwhile, construction difficulty and construction cost are reduced, and environmental pollution is reduced.
一种环保型高强固化土施工工艺，施工工艺流程为：施工放样→挖基坑→摊铺水泥→路拌机干拌→初压→稀释和喷洒环保型高强固化剂→再拌合→复压→刮平→碾压→养生；或为施工放样→挖基坑→摊铺水泥→冷再生设备拌合→初压→刮平→碾压→养生。上述施工工艺中环保型高强固化土配合比设计为：有机类固化剂:水泥:基质土＝(0.01％～0.05％):(2％～15％):(85％～98％),无机类固化剂:基质土＝(3％～18％):(82％～97％)。该施工工艺可保证环保型高强固化土固化后理化性能及力学性能优异，改善基质土块的破碎效果、水泥的缓凝效果及提高无机结合料水化的早强效果，提高固化土的可再碾压性；同时，降低施工难度和工程造价，减少环境污染。
