The Construction Methods of the Stone Weirs: A. Prying
-
This construction method can be used for the stones which are covered or sedimented under the sea. It’s often used to clear up the remaining base of the stone weirs. At first, the repairmen will step on the nail puller by foot or soak themselves in the sea, thrust the nail puller into the gap between the stone and the silt, leverage and loose at the bottom of the large-sized stone which can’t be moved by manpower easily, flip the stone, then adjust a suitable angle for the stack up.
