This invention relates to the field of caisson bottom sealing construction technology, and discloses a dynamic sealing sludge and water inrush sealing system for caissons. The system integrates a bottom sealing template assembly, a dynamic sealing baffle, a novel quick-setting sealing grout injection assembly, a drainage and pressure relief assembly, a fixing and anchoring assembly, and an anti-sludge isolation assembly. The bottom sealing operation is completed through an integrated process of layered sealing, immediate curing, and simultaneous bottom sealing. During construction, the base is first cleaned and the components are installed; after the dynamic sealing baffle is deployed, it is hydraulically attached to the base plate and the water inrush point is detected; then, quick-setting grout is injected into the leakage area in a targeted manner, and drainage and pressure relief are simultaneously activated to regulate the pressure; after the grout has quickly set, the baffle is retained as a permanent water-stopping structure; finally, underwater concrete is continuously injected through a pre-set pipeline, and an anti-sludge isolation layer is set to ensure the density of the concrete. This system simultaneously achieves rapid water inrush sealing, dynamic pressure balance, and high-quality bottom sealing, solving the problems of poor sealing time, poor process connection, and difficulty in controlling the quality of underwater concrete in traditional processes.
