PURPOSE:To correct the uneven subsidence of a storing tank into a normal state by supplying compressed air into several compartments divided by partition walls under a storing tank and opened in bottoms. CONSTITUTION:There are shown a storing tank 1 installed in a soft ground 2 and a floating lid 3. Under the bottom of the storing tank 1, several compartments 4,5, and 6 divided by partition walls 7,8,9, and 10 respectively are provided. When the storing tank 1 is subsided unevenly, the subsidence is detected by the relation between scale beams 19 planted on a ground surface 2a and pointers 18 arranged upon the tank 1. Then, a compressed air supplying device 17 is driven to supply compressed air into compartments 4, 5, and 6 under the storing tank 1 unevenly subsided under the control of control valves 14, 15, and 16 for correcting the subsidence of the storing tank 1 into a normal state. |
