1. There should be no high-voltage poles, underground pipelines, fixed machinery and equipment and permanent buildings in the affected area around open caisson sinking. Safety measures should be taken when necessary.
2. The air storage tank of the air compressor should be equipped with a safety valve, and the gas transmission pipe should be numbered. Professionals should be responsible for gas supply control. Divers should have filters when working, and the air inlet should be located where clean air can be obtained.
3. The height of open caisson should not make the center of gravity too high from the ground, the length should not exceed the short side or diameter of open caisson, and generally should not exceed 12m. Special circumstances allow heightening, but reliable calculation data should be available and necessary technical measures should be taken.
4. When the scaffold inside and outside the open caisson cannot sink with the open caisson, it should be separated from the open caisson template and steel bar. No facilities such as tic-tac-toe frames and escalators shall be fixed on the well wall to prevent the open caisson from being pulled down when it suddenly sinks.
5. Protective railings should be set around the top of open caisson. Construction facilities such as pumps and hydraulic machinery pipelines in the well should be firmly erected to prevent falling.
6. Before the open caisson sinks, the pull rod bolts and round nails on the borehole wall should be cut off. Especially when sinking without drainage, the obstacles and steel dowel in the well should be removed to prevent the diver's diving suit from being cut.
7, pumping bearing stow-wood, should have a unified command, regional, in order.
8, pumping bearing stow-wood and sinking, it is forbidden to personnel from the blade foot, bottom beam and partition wall.
9. When the open caisson has a large area and sinks without drainage, there should be holes for divers to pass through on the partition wall in the well.
10. The height of the waterproof enclosure wall of floating caisson above the water surface shall not be lower than 1m at any time.
