摘要
南京地铁小行车辆基地在软土地基处理中 ,根据工程地质条件 ,将原设计的粉喷桩及时调整为深搅桩 ,既保证了施工质量 ,又节省了大量资金。该工程实践表明 ,在工程施工中 ,根据施工条件与施工效果 ,及时调整施工方案是十分重要和必要的。
According to the engineering geological condition, original powder-jetting piles because of frequent mechanical accidents, the design depth is difficult to be obtained, deep stirring piles are adjusted in time during the treatment of soft foundations in Xiaohang section of Nanjing subway. With a special deep blender, a solidated material of cement and the soft ground are fully mixed to form deep stirring pile with high intensity under the physical and chemical reactions. Then, the adjustment ensures quality and saves on a large funds for the cnstruction. The fact shows that it is very important to adjust the project of construction in time in accordance with the situation of construction and geological conditions.
