Soft foundation reinforcement treatment method
The invention discloses a soft foundation reinforcement treatment method, which relates to the technical field of soft foundation reinforcement, and specifically comprises the following steps: S100, preparing a slurry layer; s200, soil pretreatment is carried out; s300, laying a mud base layer; s400, a reinforcing layer is laid, specifically, next to the step S300, the portland cement prepared in the step S100 is laid on the surface layer of the mud base layer, the laying thickness ranges from 20 cm to 30 cm, and vibration tamping is conducted through a cement vibration rod; s500, erecting a drainage layer; s501, a foundation pile is erected; and S600, laying a slurry top layer. According to the soft foundation reinforcement treatment method, CaO can rapidly react with water to generate Ca (OH) 2 so as to neutralize redundant water in slurry, the generated Ca (OH) 2 has a promoting effect on a hydration reaction of cement mortar and can improve the strength and hardening speed of the cement mortar, and due to the addition of CaO, the effect of a water reducing agent in the cement mortar can be enhanced, so that the strength and hardening speed of the cement mortar are improved. The water-cement ratio of the mortar is effectively reduced, and a better use prospect is brought.
本发明公开了一种软基加固处理方法，涉及软基加固技术领域，具体包括如下步骤：S100、泥浆层制备；S200、土壤预处理；S300、泥浆基层铺覆；S400、加固层铺覆：紧接上述步骤S300，将步骤S100中制备的硅酸盐水泥铺设于泥浆基层的表层，铺设厚度为20ˉ30cm，并通过水泥震动棒震动夯实；S500、排水层架设；S501、基桩架设；S600、泥浆顶层铺覆。本发明所述的一种软基加固处理方法，CaO可以与水迅速反应生成Ca(OH)2，以此中和泥浆中多余的水分，并且生成后的Ca(OH)2对水泥砂浆的水化反应有促进作用，可以提高水泥砂浆的强度和硬化速度，并且因CaO的加入，可以增强水泥砂浆中减水剂的作用，以有效降低砂浆的水灰比，带来更好的使用前景。
