ABSTRACT

Underwater construction works as observed by the engineers and designers are considered as the most difficult work. Caissons are sunk through ground or water to exclude water and semi-fluid material during the process of excavation of foundations and which subsequently becomes an integral part of the substructure. In this paper, a brief description of the open caisson is done which is constructed using under water techniques. tremie method for concrete placement is discussed. The general description of open caisson in detail, its technical aspects, improvement in new techniques and also its advantages and disadvantages are discussed. The aim of this paper is to focus on small aspects included in under water construction through caisson which are highly cost consuming structures, to give a better and stable foundation for carrying heavy and dynamic load underwater concrete.

Keywords: self-consolidating concrete, flow ability, viscosity enhancement, washout resistant
