HC工法组合桩在软土地区基坑支护中的应用

Application of HC Construction Combined Piles in Foundation Pit Support in Soft Soil Area

HC工法组合桩是一种新型组合式型钢基坑支挡结构,具有高强度、高刚度和良好的抗侧倾能力。以浙江省台州市某工程项目为工程背景,介绍了HC工法组合桩在软土地区基坑支护中的应用,阐述了基坑支护设计、施工方法及要点,并分析了基坑监测数据。工程实践表明,HC工法组合桩在软土地区基坑支护中应用效果优良,可提供稳定支撑结构且对周边环境及地下管线的影响较小。

HC construction combined pile is a new type of combined steel retaining structure for foundation pit,which has high strength,high stffness and good anti-roll ability.Based on a project in Taizhou,Zhejiang Province,the application of HC construction combined pile in foundation pit support in soft soil area is introduced.The foundation pit support design,construction methods and key points are expounded.And the monitoring data of foundation pit is analyzed.It is showed in the engineering practice that HC construction combined pile can be excellently applied to the foundation pit support in soft soil area,which provides stable support structure and has litle influence on the surrounding environment and underground pipeline.
