    TECHNICAL PART
    This invention relates to an open caisson structure and construction.
    BACKGROUND
    The open caisson construction is a technology for creating a deep foundation or an underground structure. The open caisson construction is done by making a reinforced concrete caisson on the ground or in an excavation and excavating the earth inside the caisson layer by layer after the concrete strength has reached a certain level. With the soil surface getting deeper and deeper in the course of the excavation, the caisson overcomes the frictional resistance on the side surfaces and the reaction on the cutting edges by its own weight or by other measures, so that it gradually subsides until it reaches the design height, and then the Soil sealing construction carried out.
    The open caisson structure has the following advantages: Allows building at great depth (up to over 50 meters) in a narrow building area with minimal impact on the environment; Applicability in regions with complex geological and hydrological conditions; Avoid the use of complicated machines; and reducing the amount of soil that needs to be dug, transported and backfilled compared to large-scale excavation.
