布袋注浆桩施工工艺及造价指标分析

根据布袋注浆桩施工情况，结合现场施工记录和收集的资料，对布袋注浆桩从施工工艺流程的设计到成孔设备的选择，从振动沉管机成孔施工步骤到注浆中注浆管及布袋绑扎、下放、拌制浆液及注浆都作了详细的分析。并根据人员组织、材料消耗和主要施工机械设备的消耗，对布袋注浆桩施工技术的造价成本指标进行了分析。

Injection pile construction technology and cost index analysis thereof

According to the situation of injection pile construction and combined with the field construction log and data collected,this article makes a detailed analysis of those from the design of construction technological process of injection piles to the choice of hole forming equipment;and from the hole forming construction procedures of vibration tube sinking machine to the tying and lowering of the injecting pipe and geo-textile bags,grout mixing and injection grouting.Based on the personnel organization,material consumption and the consumption of main construction machinery,an analysis is also performed of the injection pile cost index.
