武清商务区钻孔灌注桩施工成本管理及质量把控

Cost Management of Bored Grouting Pile Construction and the Quality Control

随着钻孔灌注桩技术的普及导致市场竞争的加剧,如何在把握好成桩质量的前提下控制好施工成本成为取得良好经济效益的关键。以武清商务区二期工程为例,对钻孔灌注桩施工成本管理及质量把控进行介绍。在成本管理方面,主要介绍了如何编制好成本计划和如何有效控制成本;在质量把控方面,主要介绍了与成本控制相关的钻头直径与桩径、桩顶的混凝土质量等的控制。

The popularization of bore grouting pile technology gives rise to more intensified market competition, how to con- trol the construction cost under the premise of good quality control is the key to achieve good economic benefits. With the case of the second phase project of Wuqing business district, the paper introduces the cost management and quality control in bored grouting pile construction. In cost management, how to prepare cost plan and effectively control the cost are de- scribed ; in quality control, the control on bit diameter and pile diameter related to cost control as well as the quality of con- crete at the top of pile are introduced.
