双排钢管桩结合复合土钉墙基坑支护施工技术

The construction technology of double steel pipe pile composite soil nailing wall foundation pit

针对工程中基坑开挖深度较深,距已有建筑物较近,基坑无法正常放坡的情况,提出了双排钢管桩结合复合土钉墙基坑支护施工技术,并阐述了该方法的施工技术要点,解决了工程建设中的疑难问题。

According to the situation of deeper foundation pit excavation depth,near to existing buildings,not normal slope of foundation pit in engineering,this paper proposed the construction technology of double steel pipe pile composite soil nailing wall foundation pit,and elaborated the construction technology key points of the method,solved the difficult problems in engineering construction.
