Method for chemically improving lacustrine facies peat soil and application
The invention discloses a method for chemically improving lacustrine facies peat soil. The method comprises the following steps of: 1, mixing a chemical modifier into the lacustrine facies peat soil, uniformly stirring and compacting, and sealing to obtain a prefabricated part; and 2, maintaining the prefabricated part to obtain the chemically improved lacustrine facies peat soil. The invention further discloses an application of the method for improving the lacustrine facies peat soil on site; chemical modifier slurry is injected into the lacustrine facies peat soil within the on-site stirring depth range through a three-shaft deep stirring machine, and then two-time spraying and three-time stirring are conducted; starting from the components of the soil, the lacustrine-facies peat soil is reinforced by adopting a chemical improvement method; the cement reacts with organic matters in the lacustrine-facies peat soil to generate a reinforcing effect, and is coagulated and hardened to form a cement-soil framework, so that the strength of the soil body is improved; and meanwhile, hydration products are gradually lapped to form a stable network structure by controlling the water-cement ratio, so that the strength of the improved lacustrine facies peat soil is further improved; and the application of the invention improves the strength of the improved lacustrine facies peat soil.
本发明公开了一种化学改良湖相泥炭质土的方法，该方法包括：一、向湖相泥炭质土中掺入化学改良剂后搅匀压实，经密封闷料得到预制件；二、预制件养护得到化学改良后的湖相泥炭质土；本发明还公开了上述方法现场改良湖相泥炭质土的应用，采用三轴深搅机对现场搅拌深度范围内的湖相泥炭质土注入化学改良剂浆液，然后进行两喷三搅。本发明从土的成分入手，采用化学改良法加固湖相泥炭质土，通过水泥与湖相泥炭质土中的有机质反应产生加固作用，并凝结硬化构成水泥土骨架，提高了土体强度，同时通过控制水灰比使得水化产物逐渐搭接形成稳定的网络结构，进一步提高了改良后湖相泥炭质土的强度；本发明的应用提高了改良后湖相泥炭质土的强度。
