AI Technical Summary
In deep foundation pits and vertical ultra-deep caisson projects, underwater sediment is difficult to clean thoroughly, resulting in reduced concrete density and impermeability, and poor sealing effect. Traditional inorganic curing agents have slow curing speed and low strength in high moisture content environments, and organic materials are easily degraded underwater, making it difficult to achieve large-scale application of existing construction techniques.
The polymer material, which uses an alkali-activated system and multi-component modifiers, is solidified in situ underwater with sediment through a high-pressure jetting process to form a high-strength, impermeable sealing layer. The material design takes into account the reaction stability and mixing uniformity in high moisture content environments, and the supporting equipment is adapted to complex underwater terrain.
It enables rapid solidification of underwater sediment, forming a high-strength, well-integrated sealing layer, improving construction efficiency and project adaptability, reducing project costs, and the material is non-toxic and harmless, suitable for complex underwater working conditions.
