基于价值流图的高速公路路面施工管理

摘要

To improve the reliability and stability of the pavement construction process,this research implemented improvements based on the value stream map(VSM). Firstly,through the field data collection,this research drew the current-state map of the pavement construction. We diagnosed incompact construction process,unstable production rhythm,construction delay and quality defect via analyzing the current-state map. Aiming at above problems,this research proposed five improvement measures from three aspects:construction team,process flow and project site. Comparing with the future-state map of the pavement construction,the schedule,quality and occupational health and safety(OHS)of the pavement construction process has significantly increased. This research of pavement construction management based on VSM provides case studying reference and theory support for the lean construction.%为提高高速公路路面施工流程的可靠性和稳定性，基于价值流图进行施工管理改进。通过收集现场数据，绘制路面施工的现状价值流图。分析发现施工过程中存在工序不紧凑、生产节拍不稳定、工期拖延和质量缺陷等施工管理问题。针对这些问题，从施工团队、工序流程和项目现场三方面提出了改进措施。通过与路面施工未来价值流图的对比，精益改进的实施使公路路面施工流程在工期、质量和职业健康安全指标上得到显著提升，为公路项目的精益管理提供了实际案例借鉴和理论方法支持。
