摘要
THC36型号高速液压夯实是对已完成的桥台、涵台、墙背回填在各项指标检测合格的情况下,进行补强的一种措施,按一定的间距密度进行液压夯实处理,提高台背的压实度,进一步消除因工后三背回填自然沉降而造成的公路运营过程中出现的桥涵跳车、墙背沉陷问题。
THC36 high speed hydraulic compaction is a kind of reinforcement measures, under the completion of the bridge abutment and culvert wall and backfill in passing the test indicators condition. Hydraulic tamping treatment according to certain spacing density, to improve back compaction, and to eliminate the bridge jumping and wall subsidence during highway operation process which caused by natural settlement after backfilling .
