Comprehensive foundation treatment method for reinforcing silt soft soil
The invention discloses a comprehensive foundation treatment method for reinforcing silt soft soil, and relates to the technical field of geotechnical engineering foundation reinforcement treatment. A double-layer foundation treatment mode is adopted, and the method comprises the specific treatment steps that (1) a stirring pile machine is adopted to drill into a silt soft soil layer in the mode of being perpendicular to the ground, cement or cement paste is sprayed into the silt soft soil while drilling is conducted, and the sprayed cement or cement paste and the silt soft soil in drilled holes are fully stirred; then the cement and the silt soft soil mixture are subjected to a series of physical and chemical reactions to be gradually hardened, the vertical cement soil mixing piles are formed after the mixture is hardened, the piling operation is repeated, and therefore the cement soil mixing pile reinforcing layer with the multiple cement soil mixing piles evenly distributed on the silt soft soil is obtained; the height of the cement soil mixing pile is consistent with the thickness of the silt soft soil; wherein the cement or the cement paste is sprayed into the silt soft soil according to the proportion that the cement doping amount accounts for 12-20% of the weight of the silt soft soil; and (2) performing layered compaction on the cement-soil mixing pile reinforcing layer to form a broken stone hardcore.
本发明公开了一种加固淤泥软土的综合地基处理方法，涉及岩土工程地基加固处理技术领域。本发明采用双层地基处理方式，具体处理步骤为：(1)先采用搅拌桩机械垂直地面钻入淤泥软土层，边钻边将水泥或水泥浆喷入淤泥软土中，并将喷入的水泥或水泥浆和钻孔内的淤泥软土进行充分搅拌，而后使水泥和淤泥软土搅拌物发生一系列物理化学反应逐渐硬化，搅拌物硬结后形成垂直的水泥土搅拌桩，重复该打桩操作，从而得到若干根水泥土搅拌桩均布于淤泥软土的水泥土搅拌桩加固层，所述水泥土搅拌桩的高度与淤泥软土的厚度一致；其中，水泥或水泥浆按照水泥掺入量占淤泥软土重量12～20％的配比喷入淤泥软土；(2)在水泥土搅拌桩加固层上分层压实形成碎石垫层。
