Environment-friendly land making method for layered reinforcement of engineering muck and soft soil foundation
The invention discloses an environment-friendly land making method for layered reinforcement of engineering muck and a soft soil foundation. The land making method comprises the following steps of performing vacuum preloading reinforcement treatment on the engineering muck, and performing shallow reinforcement construction on the surface layer of the engineering muck by adopting a reinforcing agent. According to the method, a whole surface solidification layer can be formed by solidifying an integral solidification material of the surface soil body, integral plate-shaped pressing can be conducted on the soil body during vacuum preloading treatment in the later period, the sealing performance and the pressure borne by a vacuum preloading area below the soil body are improved, water in a solidification material solidification area can be discharged downwards through a pumping and discharging system, and the vacuum preloading pumping drainage effect is improved, and due to the fact that the pressure of the soil body is gradually decreased from top to bottom to the depth of the soil body after the soil body bears the pressure, the reinforcing method can form a whole reinforcing layer with large bearing capacity on the surface layer, the whole reinforcing layer can disperse the pressure to a larger area, the possible sinking amplitude is reduced, and a multi-composite bearing capacity can be obtained by matching with a vacuum preloading pumping area below.
本发明公开了一种分层加固工程渣土和软土地基的环保造地方法，对工程渣土进行真空预压加固处理，在工程渣土表层采用加固剂进行浅层加固施工。上述方法能够通过在表层土体的整体式固化料固化形成整块的表面固化层，后期进行真空预压处理时能够对土体进行整体式板状下压，提升密封性和下方真空预压区域承受的压力，有利于将固化料固化区的水分向下通过抽排系统排出，且提升真空预压抽排效果。由于土体在承压后压力自上而下向土体深处逐渐递减，本发明的加固方法能够在表层形成整块且大承载力的加固层，整块的加固层能够将压力向更大面积分散，降低可能下沉的幅度，配合下方的真空预压抽排区域能够获得多重复合式的承载力。
