Abstract:
According to the variable degrees of settlement of the local high roadbed and the back of bridge and culvert in Hengshui track division of Beijing-Jiulong, static pressure grouting and gravity grouting consolidation were selectively used for about 5000 running meters in these 2 years. By the train operation limitation of rail allowance to the level undulating, most high roadbed grouting volume is normal, but there are part insufficient grouting. It is often seen that the grouting effects are good in the back of bridge and culvert, supporting cone and some frequent subsiding high roadbed with large amount of grouting, which solves subsequent settlement; while the technical process still should be studied for those high roadbed with small amount grouting to treat settlement.
