黄泛区旋挖钻混凝土灌注桩基施工技术

Construction Technology of Cast-in-place Pile Foundation for Rotary Drilling in Yellow

桩基进行施工常出现沉渣过厚,泥浆护壁过厚,使桩基的承载力达不到设计的要求生,使工程的施工质量受到影响。通过对新建郑州至周口至阜阳的铁路工程进行分析,着重介绍旋挖钻混凝土灌注桩基的施工技术的应用。

In the construction of pile foundation, the sediment is too thick and the mud wall is too thick, so that the bearing capacity of the pile foundation can not meet the design requirements. The construction quality of the project is affected. In this paper,through the analysis of the new railway project from Zhengzhou to Zhoukou to Fuyang, the application of the construction technology of the pouring pile concrete pouring pile foundation is introduced emphatically.
