SCAFFOLD TO BE ERECTED INSIDE TANK AND RECOVERY OF DEAD STOCK THEREIN

摘要

PURPOSE: To enhance the workability and shorten the construction period, by inserting working scaffolds from a manhole at the top cover to take out the inside contents of the tank and inspect them and also clean the inside of tank. ;CONSTITUTION: One end of a step 3 is rotatably attached to an axis at the lower part of a post 1 and unified with the post 1 along the post 1 when inserting in a tank and further, after it has been inserted, it is kept horizontal to serve as a scaffold. The deadstock in the tank is discharged to the outside by use of a suction hose 22. In this time, the suction hose 22 is extended into the tank through the manhole at the top cover and placed on the step 3. In this way, the pulverulent dead stock in the tank can be safely and efficiently recovered.;COPYRIGHT: (C)1994,JPO&Japio
