Sinking apparatus for sinking concrete shaft
A sinking apparatus for sinking a concrete shaft includes a water tank, a valve assembly, a communication pipe, and a pumping device. The water tank is disposed on an upper surrounding edge of the concrete shaft, and has a water outlet port. The valve assembly includes a valve gate which is operable to open and close the water outlet port. The pumping device is disposed to permit water inside a central hollow portion of the concrete shaft to be pumped into a water accommodation space of the water tank through the communication pipe.
