Device and method for reinforcing calcareous sand foundation through CO2
The invention provides a device and method for reinforcing a calcareous sand foundation through CO2, and belongs to the technical field of civil engineering foundation treatment. The device for reinforcing the calcareous sand foundation through the CO2 comprises a CO2 gas supply device and an aeration pipeline, wherein the CO2 gas supply device is communicated with the aeration pipeline through a gas outlet; the to-be-reinforced calcareous sand foundation comprises a calcareous sand stratum, a coral gravel permeable cushion layer and a natural stratum, the coral gravel permeable cushion layer is arranged above the natural stratum, and the calcareous sand stratum is arranged above the coral gravel permeable cushion layer; the aeration pipeline is arranged in the interlayer of the coral gravel permeable cushion layer, a plurality of aeration micropores are formed in the aeration pipeline, and the average pore size of the aeration micropores ranges from 0.3 mm to 0.6 mm. The method for reinforcing the calcareous sand foundation through the CO2 is achieved based on the device for reinforcing the calcareous sand foundation through the CO2. And macroscopically, a cementing effect is generated on a calcareous sand stratum, and the overall strength and the liquefaction resistance of a calcareous sand foundation are improved.
本发明提供一种CO2加固钙质砂地基的装置及方法，属于土木工程地基处理技术领域。该CO2加固钙质砂地基的装置包括CO2气体供应装置和曝气管线，CO2气体供应装置通过出气口与曝气管线连通；待加固钙质砂地基包括钙质砂地层、珊瑚碎石透水垫层和天然地层，珊瑚碎石透水垫层设置于天然地层的上方，钙质砂地层设置于珊瑚碎石透水垫层的上方；曝气管线设置于珊瑚碎石透水垫层的夹层内，曝气管线上设有多个曝气微孔，曝气微孔的平均孔径取值范围为0.3‑0.6mm。该CO2加固钙质砂地基的方法基于该CO2加固钙质砂地基的装置而实现。其在宏观上对钙质砂地层产生胶结作用，提高了钙质砂地基的整体强度和抗液化性能。
