某工程冲孔灌注桩充盈系数偏高原因分析及对策

Cause Analysis and Countermeasures for the High of Punch Filling Pile Filling Coefficient of the Engineering

冲孔灌注桩近年在广东等沿海地区高层建筑和桥梁基础中应用较广泛,但施工过程中常会遇到因混凝土充盈系数偏高而导致工程成本增加、利润降低的问题。文中分析某基础工程施工冲孔灌注桩混凝土充盈系数偏高的原因,探讨其解决对策,及其实施效果和经济、社会效益。

The technology of punch filling piles has more widely used in Guangdong and other coastal areas of high-rise buildings and bridge foundation in recent years.But in the process of construction often encountered due to concrete filling coefficient high and leading to increased costs,reduced profit problem.To solve this problem,in this paper,based on the analysis of the basic construction of punch filling piles in the course of concrete filling coefficient increases as the reason,to explore solutions to this problem,and measures the results achieved with the implementation of economic and social benefits.
