摘要
深基坑支护在砂性土中采用SMW工法桩结合可回收加筋水泥土桩锚,除角撑外无内支撑,施工灵活,施工工作面开敞,挖土比较方便,施工方法简单,但须专业施工队伍施工,具有工期快,成本低等特点。以实际工程为例,该深基坑不设内支撑的成功应用,体现了安全、经济、适用、环保、节能、缩短工期等。为当前推广和倡导的绿色施工供同行参考。
It can reclaim the reinforced soil pile anchor when adopted SMW pile in deep foundation pit supporting under sandy soil conditions, which has no inner support except for the angle support and its construction is flexible, the construction work face is open, and also its excavation is more convenient; although the technical construction method of reclaim the reinforced soil pile anchor is simple, it need professional construction team, it has the characteristics of quick construction and low cost. This paper took practical engineering as an example, analyzed the successful application of the deep foundation pit without inner support mainly embodied safety, economy, application, environmental protection, energy conservation and shortening the construction period, which could be for the current promotion and advocacy of green construction for peer reference.
