深基坑微型桩与预应力锚索腰梁组合支护技术

Technology of Combined Support of Micropile and Prestressed Anchor Rope Beam in Deep Foundation Pit

结合新郑泥河新城深基坑支护工程,介绍该组合支护设计施工参数,施工工艺流程,以及此支护技术在泥河新城深基坑复杂室外管网环境下的使用,同时研究在此组合技术下如何降低对基坑施工范围内管线及建筑物监测数据的影响。

This article combines the deep foundation pit support project of Nihe New City in Xinzheng,introduces the design and construction parameters,construction process flow of the combined support,and the use of this support technology in the complex outdoor pipe network environment of deep foundation pit in Nihe New City.Study how to reduce the impact on the monitoring data of pipelines and structures within the scope of foundation pit construction under this combined technology.
