布袋注浆桩施工工艺及造价指标分析

Injection pile construction technology and cost index analysis thereof

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。

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.
