微型钢管桩+喷锚支护方法在某项目基坑支护的应用

Application of the Method of Adding Micro Steel Tube Pile to Anchorage and Chotcrete Support in Foundation Pit Support of a Project

通过工程实例,介绍微型钢管桩加喷锚支护在场地狭窄条件下的使用,既保证了基坑的安全,又缩短了工期,取得了较好的经济效益,更重要的是解决了由于场地狭窄,大型机械设备无法施工的难题,在同类型基坑中值得推广应用。

Though there are several support schemes, when either the construction site is narrow or the shallow foundation pit is near the buildings around, the best method to choose is adding micro steel tube pile to anchorage and chotcrete support. The utilization of this method applied in narrow site is introduced based on example project, which not only assure the safety of foundation pit, reduce the time, but also obtain the good economic efficiency, and what＇ s more, it solves the problem that large-scale mechanical device is unable to work in so narrow site with the other foundation pit support methods, so the method is worth popularizing in same kind of foundation pit.
