桥下回填砂填筑施工管理措施研究

Research on Management Measures for Backfilling Sand Filling Construction under Bridges

在桥梁工程中,为了保护桥墩和增强桥体的稳定性,需要在桥下进行回填砂填筑。回填砂是一种轻质、透水性较好的施工材料,可以有效减少桥体自重,保护桥墩,防止水流冲刷和侵蚀。在回填砂填筑过程中,需要选择合适的砂料,并进行充分搅拌和压实,以确保填筑质量。文章结合实际案例,分析了桥下回填砂填筑施工顺序,探讨了桥下回填砂填筑施工管理措施,以供参考和借鉴。

In bridge engineering,in order to protect the bridge piers and enhance the stability of the bridge body,it is necessary to conduct backfilling sand filling under the bridge.Backfilling sand is a kind of construction material with light weight and good permeability,which can effectively reduce the weight of the bridge,protect the bridge pier,and prevent water scour and erosion.In the process of backfilling sand filling,it is necessary to select appropriate sand materials,and fully stir and compact them to ensure the filling quality.Based on the actual case,this paper analyzes the construction sequence of backfilling sand filling under the bridge,and discusses the management measures of backfilling sand filling construction under the bridge for reference.
