建筑地基基础下深埋式防空洞的处理

Treatment Technology of Deep Buried Air-raid Shelter Under Building Foundation

以常德碧桂园 十里公园项目A地块为工程实例,阐述建筑地基基础下部深埋式防空洞处理关键技术。介绍了灌注桩长螺旋桩机全护筒成孔施工技术及单柱承台独立施工技术在防空洞处理中的操作方法。实践证明,采用以上技术对深埋式防空洞进行处理是合理、适用的,既能保证质量,又能节省费用。

Taking the plot A of Chan gde Country Garde n Shili Park project as an example, the key tech no logy of deep buried air-raid shelter treatment under the building foundation is expounded. The hole forming construction technology of the full pile casing of the long screw pile driver of the cast-in-place pile and the operation method of the independent con structi on tech no logy of the single pile cap in the air-raid shelter treatme nt are in troduced. The practice proves that the above tech no logy is reasonable and applicable to deal with the deep buried air defe nse tunnel, which can not only ensure the quality, but also save the cost.
