Roadbed curing auxiliary workpiece suitable for soft foundation soil and application of roadbed curing auxiliary workpiece
The invention relates to a roadbed solidification auxiliary workpiece suitable for soft foundation soil and application of the roadbed solidification auxiliary workpiece. Two parallel vertical formworks are arranged as unit pieces and are provided with splicing adapters respectively, and detachable supporting frames are arranged on the outer side faces of the vertical formworks; in the construction process, after the drainage cushion layer is laid, the number-adjustable vertical formworks and the number-adjustable supporting frames are installed, slurry with the high water content is injected, drainage is conducted after standing is conducted, solidification is conducted till the water content of the slurry is reduced to a target value, after solidification is completed, the vertical formworks are pulled up and recycled, filling of an embankment slope is conducted, and a complete roadbed is obtained. A mud pit does not need to be built, land is saved, and the pre-pressing period of the foundation can be effectively prolonged; the working procedures are few, control is easy, and the construction period and the project quality can be well balanced; compared with a rolling type solidified soil roadbed control method, the method is simple, the dehydration effect is good, the construction period is short, and the influence of weather factors is small; the vertical formwork is high in standardization degree, and the transportation cost is greatly reduced.
本发明涉及一种适用于软弱地基土的固化路基辅助工件及其应用，设置并列的2个竖向模板作为单元件、分别设置拼装适配件，在其外侧面设置可拆卸支撑架；施工中，铺设排水垫层后，安装可调数量的竖向模板和支撑架，注入高含水率的泥浆，静置后进行排水，直至泥浆的含水率降至目标值后进行固化，完成固化后将竖向模板上拔回收，进行路堤边坡的填筑，得到完整路基。本发明无需泥浆池的修建，节省用地，并且能有效增加地基的预压期；工序少，控制简单，能较好地平衡工期和工程质量的施工方法；相比碾压型固化土路基控制方法简单，脱水效果好，工期短，且受天气因素影响小；竖向模板标准化程度高，运输成本大幅降低。
