Abstract: Non-dispersible soil-cement for underwater reinforcement, and a construction method. Underwater natural sand or sand containing mud that is sucked up, water, an anti-dispersing agent, and an early strength agent are mixed and stirred to form non-dispersible soil-cement, and then the non-dispersible soil-cement is poured underwater by means of a pipe, or placed in geotextile bags and thrown underwater, to form a continuous underwater reinforcement surface. Raw materials are obtained locally, thereby reducing transportation costs and storage yard costs. Sand suction, stirring, and pouring or bag throwing can be performed on a dredging vessel on site, and the dredging vessel can continuously move for continuous construction; thus, the construction is convenient and quick. The soil-cement formed by stirring can be quickly consolidated due to the addition of the early strength agent, and is non-dispersible underwater due to the addition of the non-dispersing agent and thus can continuously react underwater to reach the desired strength at different ages. Finally, a permanent underwater protective layer is formed.
