Research on Management Measures for Backfilling Sand Filling Construction under Bridges
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.
