锚定搅拌桩基坑支护的应用

将土层锚杆直接锚定在强度相对较低的“薄型”搅拌极墙上,锚下用槽钢作为受压铁件与搅拌极相接触。该支护工艺打破了以往搅拌极只设计成重力式厚挡墙及作为与灌注极配合作为挡水帷幕的传统做法,节省了工作量,做到安全度高、造价低、噪音小、无污染、施工占有场地窄,可造用于闹市区或有邻近建筑的基坑支护旅工。

Application of Anchored Agitation Pile to Foundation Pit Bracing

The anchor rod is anchored directly on the agitation pile wall of "thin type" with relatively low strength and channel bar is used under the anchor to contact with the agitation pile. This bracing process is different with the traditional method of using the agitation pile only as thick bulkhead together with the cast-inplace pile. Quantity of work is saved by this method, with high safety and low cost,low noise, no pollution. It fits for foundation pit bracing in urban district as a li-mited site will be enough for its construction.
