Summary:The novel open caisson bottom sealing concrete water stop construction method comprises the following steps that S1, an annular groove is formed in the bottom of the inner wall face of an open caisson, a rubber air bag in an uninflated state is pre-arranged in the annular groove, and the rubber air bag is in an annular shape matched with the annular groove; s2, after the open caisson sinks to the designed elevation, bottom sealing concrete is poured at the bottom of the open caisson, and the annular groove is located in the pouring depth range of the bottom sealing concrete; and S3, after the bottom sealing concrete is cured to reach the required strength, the rubber air bag is inflated through an air bag inflation pipeline till the gap between the bottom sealing concrete and the inner wall face of the open caisson is filled with the rubber air bag. The open caisson bottom sealing concrete water stop structure has the advantages that compared with a traditional open caisson bottom sealing concrete constructio
