PURPOSE: To enhance workability by forming a cylindrical body with upright reinforcements, ring reinforcements and expand metals and installing the cylindri cal body around a temporary vertical collecting metals basin and filling up rubble stones in there. ;CONSTITUTION: Six upright reinforcements and three ring reinforcements are welded so as to constitute a skeleton. Expand metals 4 are welded with the whole surface inside the skeleton, thereby forming a cylindrical body 1. The cylindrical body 1 is installed around a temporary vertical collecting manhole 5. Rubble stones 8 are filled up in a space between the vertical collecting manhole 5 and the cylindrical body 1 by using a back hoe 7. This construction makes it possible to reduce onsite construction work dramatically and enhance the construction speed of the temporary vertical collecting basin.;COPYRIGHT: (C)1995,JPO
