Double-layer low-position vacuum-preloading consolidation device and soft soil foundation consolidation method
The invention belongs to the technical field of consolidation of soft soil foundations, and discloses a double-layer low-position vacuum-preloading consolidation device and a soft soil foundation consolidation method. The double-layer low-position vacuum-preloading consolidation device comprises an initial air pressure detection module, an air exhaust module, a vacuum degree detection module, a central control module, a blow-filling consolidation module, a soft soil consolidation module, a vacuum ballast module, a drainage module, a settlement monitoring module, a soil strength monitoring module, a pore water monitoring module, a curve drawing module, a data transmission module and a display module. According to the double-layer low-position vacuum-preloading consolidation device and the soft soil foundation consolidation method, the water pressure is used as the ballast through the ballast module, the water filling and discharging process is simple and easy to implement, the construction period can be shortened, environmental friendliness is realized, the construction noise is low, and a treated foundation can meet general engineering construction requirements; and blow-filling sand can be tampered and compacted to form a large-thickness and over-consolidated high-strength hard crust to ensure that a load adopted in the future has a good stress dispersion effect, so that post-construction settlement is unlikely to occur; and the drainage effect is good.
本发明属于软土地基加固技术领域，公开了一种双层低位真空预压加固装置及软土地基加固方法，所述双层低位真空预压加固装置包括：初始气压检测模块、抽气模块、真空度检测模块、中央控制模块、吹填加固模块、软土加固模块、真空压载模块、排水模块、沉降监测模块、土体强度监测模块、孔隙水监测模块、曲线绘制模块、数据传输模块、显示模块。本发明通过压载模块采用水压作为压载，充、泄水过程简单易行，可缩短施工周期、环保、产生的施工噪音小，处理后的地基满足一般工程建设的需要；通过排水模块可对吹填砂进行夯击密实形成大厚度超固结的高强度硬壳层，对未来的使用荷载具有良好的应力扩散效应，而使工后沉降难于产生；排水效果好。
