蓟运河防潮闸始建于 1 973年 ,由于唐山地震影响 ,上部结构和闸基础受到了严重破坏。闸基础存在闸底板脱空、闸基渗流和闸基础灌注桩桩身混凝土质量差等质量问题 ,加上桩端与闸底板连接薄弱是影响防潮闸渗流稳定和整体稳定性的主要原因。
The Jixun River floodgate was built in 1973. Due to the Tangshan earthquake, the superstructure and sluice foundation were seriously damaged. The sluice foundation has the following problems: the sluice floor is not empty, the gate foundation seepage and the poor quality of the foundation piles with sluice foundation are poor quality. The weak connection between the pile end and sluice floor is the main reason that affects the seepage stability and overall stability of floodgate.
