1) The utility model intercepts the floatage on the water surface within a certain area, thus being convenient for implementing refloatation and removal.

2) The floatage state and Load rule of the buoy is analyzed. The causes are found of the buoy submersing in seawater, the alarm light signal ghosting and the buoy cable breaking off.

3) This machine is used to intercept and automatically clear the particle floatage and suspended substances in the sewage during the municipal and industrial sewage treatment.

4) In general, we often take anti-lift pile foundation to counteract the adverse effect of ground water floatage to building in sub-ground engineering.

5) The resistance to float relates to the attributes and conditions of the ground water, the pressure and floatage of water, the change of water level and the sudden supplement of water.

6) An application of three dimensional photoelastic stress analysis in a dam with drains for floatage at the Three Gorges Project is described.
