Caisson shaft sinking
WebShaft mining or shaft sinking is the action of excavating a mine shaft from the top down, where there is initially no access to the bottom.

WebThe caisson sinking method is one way to construct underground concrete structures, such as bridge piers, intake structures, pump houses and dumper pits, in soils with a high water table. In this method, a caisson is constructed on the unexcavated site, with the caisson comprising only the walls of the final structure. WebA caisson is sunk by self-weight, concrete or water ballast placed on top, or by hydraulic jacks. The leading edge (or cutting shoe) of the caisson is sloped out at a sharp angle to aid sinking in a vertical manner; it is usually made of steel.
